Since lighting and daytime operations account for a major share of this common area power consumption, common area solar for societies is one of the most effective ways to significantly reduce these costs. We’re not making this up. The numbers speak for themselves!

• Well-designed rooftop solar for apartment complexes can reduce common-area electricity costs by 50-60%.
• In societies with sufficient rooftop space and a larger system, the reduction can even reach 90%.

That happens because most of the common area loads, such as lifts, pumps, corridor lights, parking lights, and clubhouse ACs, consume electricity during the day, which naturally aligns with peak solar power generation hours.

This blog walks you through what can run on solar in a housing society’s common areas, how much solar for apartment complexes costs, the subsidies available, the benefits of using solar electricity for common areas, and how the savings are distributed to each flat.

Services that Can Run on Solar for Common Areas in Housing Societies

Almost every electrical load in your society’s common areas can be powered by solar energy. The ones that generate the most savings on your common-area electricity bills are those that run during daylight hours. That’s primarily because daytime is the time when your solar plant is generating power at its peak efficiency.

Here’s a snapshot of the most relevant services in a common area that can be powered through solar electricity for maximum savings on CAM bills.

• Solar power for water pumps: Most societies operate their pumps on a scheduled cycle during the day to fill overhead tanks. You can easily align those cycles with peak solar generation hours. Different societies use different types of solar pumps for apartments depending on their layout. Sump pumps lift water from underground tanks, booster pumps maintain pressure in tall buildings, and STP pumps handle sewage treatment. No matter the type of solar water pump used, they can all be shifted to solar.
• Solar power for lifts and elevators: An on-grid solar system can cover daytime consumption for your lifts and significantly reduce the common-area electricity bill. During power cuts and at night, you’ll need a solar lift backup. In areas with prolonged power cuts, a hybrid solar system with battery backup might make sense. In areas with a stable grid and very rare outages, a diesel generator makes more sense for solar lift backup.
• Solar lighting for apartments and common areas: Clubhouse lights, gym lights, corridor and staircase lights, and basement lights can all be powered through solar energy. Daytime lighting in basements and indoor common areas gets fully offset by solar, and the savings continue around the clock when your plant is connected via net metering.
• Security and surveillance in corridors and basements: CCTV systems, access control, intercom panels, and basement ventilation fans run continuously. These are low-wattage but high-uptime loads, and solar combined with net metering covers them efficiently.
• Parking lot lighting: Lighting in covered parking and basement parking runs during the day and evening. Your solar generation during the day offsets this consumption directly.
• Clubhouse and gym air conditioning: AC is one of the heaviest electrical loads in any society, and clubhouse and gym ACs run during daytime and early evening hours when occupancy is highest. That makes them a strong load to plan your solar capacity around.
• Street lighting and landscaping: Garden lights, pathway lights, and perimeter lighting run mostly at night, which means they get powered through net metering credits you’ve earned during the day rather than directly from solar generation.

Why Are Common Areas the Perfect Starting Point for Solar?

While there are options for individual apartments to offset their personal flat bills through solar by opting for virtual net metering, common areas are still the best starting point for any society to go solar. Need a reason to believe that? Let’s give you four.

1. Load timing works in your favor: Common-area loads run heavily during daylight hours. Pumps fill tanks during the day, lifts move residents in and out, basements stay lit, and clubhouse ACs run when the gym and lounge are in use. Solar generates power during the same hours. So, the match between generation and consumption is naturally strong. Less power is wasted or exported, and more of each unit you generate is used directly.
2. Single ownership simplifies billing and approvals: Your society’s common-area meter is a single connection to a single DISCOM, with a single bill. The RWA or managing committee runs one billing cycle and receives one set of DISCOM approvals, rather than dealing with hundreds of individual flat-level meters. The AGM still needs to vote in favor of solar for the project to go ahead, but the technical and billing sides remain simple because there’s only one meter and one connection involved.
3. Shared benefit drives consensus: Every rupee saved on the common area bill stays within the society. The managing committee decides how to use these savings. Some societies pass them through as lower maintenance charges, while others redirect the money into the CORPUS fund for repairs, painting, or future upgrades.
4. Asset clarity removes disputes: The rooftop is already a common asset owned collectively by all society members. Installing solar there doesn’t require carving up individual ownership or arguing over which flat the panels belong to. The society owns the rooftop and the plant, and the savings belong to everyone.

How Much Solar Does Your Society Need? 

Every housing society has a different power footprint. The right solar capacity depends on how many lifts you run, how many lights stay on through the night, whether you have water pumps running during the day, and how much rooftop area you have available.

For instance, a 60-flat society with two lifts and a clubhouse will need far less than a 60-flat society running a swimming pool filter and a sewage treatment plant. This is why you start with an energy audit of all common-area meters before sizing anything.

The audit provides the actual monthly consumption, which becomes the foundation for every decision that follows.

Here’s an indicative sizing guide to give you an idea:

DISCLAIMER: Treat the figures in this table as an indicative range and a starting point, not a final recommendation. Actual solar capacity needed varies based on the usable rooftop or open space you have after accounting for shading, the sunlight your city receives across seasons, your sanctioned load, and the net metering caps your state DISCOM enforces. Future additions, such as EV charging points or new amenities, also matter, since it is wiser to size for tomorrow than only for today. For an accurate number, get a site assessment from a qualified installer who can review your audit data, inspect your rooftop, and account for local regulations.

What are the Different Solar Solutions for RWAs?

Once your society decides to install rooftop solar, the next decision is how the generated electricity will be measured, billed, and credited. India has three main models for housing societies, and the right one depends on how your electrical metering is set up and on what your state DISCOM allows.

• Net metering for housing societies: This is the most common model, in which the solar plant connects to your common-area meter. Any excess generation gets exported to the grid, and your society receives credit for those units on the next bill.
• Group net metering for housing societies: In this model, a single solar plant generates electricity that gets credited across multiple meters within the same society. This works well when your society has separate meters for different blocks or different common-area circuits.
• Virtual net metering (VNM) for apartments: VNM works when the solar plant is installed at a separate location, usually on DISCOM premises. Flat owners who sign up for the plant get credits on their individual electricity bills based on the share of solar capacity they had agreed to. This works well for societies where rooftop space is limited or unavailable.

Types of Solar Systems Best for Housing Societies

There are three main types of solar systems to choose from. One is an on-grid rooftop solar system, which is connected to the grid. Second is an off-grid solar system that’s connected to a battery bank, not the grid. And third is a hybrid solar system, which is connected to the grid as well as a battery bank.

Wondering which one your society should choose? Let’s find out.

• When is an on-grid solar system better? If your society has a stable grid supply and any backup needs are already handled by diesel generators, on-grid is the recommended choice. The plant connects directly to the grid through your common-area meter, generates during the day, offsets daytime consumption, and exports the excess to earn net metering credits. Since there’s no battery, the upfront cost is the lowest of the three options, and the payback is the fastest.
• When is an off-grid solar system better? If your society faces frequent power outages and very high electricity fluctuations, and has no diesel generator backup at all, then off-grid with battery storage makes sense. The plant runs independently of the grid, and the battery handles any periods of outages when solar generation is low. This is uncommon in most urban housing societies and more relevant in semi-rural locations or areas with unreliable grid supply.
• When is a hybrid solar system better? A hybrid solar system combines solar generation with battery storage and grid connectivity. The catch is that battery energy storage systems (BESS) are very expensive, which is why hybrids are not generally recommended for societies. However, if your society specifically wants solar backup so that loads continue running on solar during a power cut, then a hybrid system can be considered.

A Practical Checklist Before Installing Apartment Solar Panels

Before your society finalizes a common-area solar installation, the managing committee must put in place the necessary legal and approval requirements. The technical feasibility step is crucial for running checks such as shadow analysis, structural assessment, and inverter placement.

• AGM approval: A formal resolution covering project scope, budget, financing model, and vendor selection authority.
• Builder NOC: Required if the society hasn’t been formed or terrace ownership hasn’t been transferred from the builder.
• Terrace and society documentation: Roof rights, society registration certificate, PAN, and the last 6 months of common-area electricity bills.
• DISCOM net metering authorization: Signed authority for the vendor to file the net metering application on your society’s behalf.

Step-by-Step Guide: Evaluating and Implementing RWA Common Area Solar

Once the legal items are in place, implementation moves through a series of phases.

• Load analysis: Share 6 months of common-area bills with your vendor to set the right system size.
• Space optimization: Vendor conducts a rooftop survey and structural inspection, and finalizes the system design.
• Legal and DISCOM approvals: AGM resolution, DISCOM net metering filing, and PM Surya Ghar Muft Bijli Yojana subsidy registration.

How Much Does it Cost to Install Common Area Solar for Societies?

To give you a ballpark range, the cost to install common area solar for societies can range from ~Rs. 60,000* per kW and ~Rs. 65,000* per kW without a subsidy.

*Please note prices are subject to change without any prior notice. The above prices are as of 22nd May 2026. The cost to install common area solar for societies varies and depends on multiple factors such as your DISCOM charges, city, solar system size, site conditions, project specifications, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc.

Most societies, however, can install rooftop solar at lower rates than this, thanks to the government subsidy, which we explain in the section below.

Is There Any Subsidy For Installing Solar for Common Areas in Housing Societies?

Yes, Group Housing Societies (GHS) and Resident Welfare Associations (RWAs) can claim a subsidy under the PM Surya Ghar Muft Bijli Yojana. If eligible, you can get a subsidy of Rs. 18,000 per kW, up to 500 kW, for grid-tied or on-grid solar plants installed for common facilities. This includes loads like lifts, pumps, lighting, and EV charging.

Here’s a snapshot of the cost to install common area solar for societies both with and without a subsidy:

*Please note that these prices are subject to change: The above-listed cost to install rooftop solar for common areas in societies for on-grid solar systems is indicative as of 22nd May 2026. The final cost of solar panel systems for housing societies depends on your DISCOM charges, city, solar system size, site conditions, project specifications, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc.

How Much Money Can Solar for Apartment Complexes Save Per Flat?

The simplest way to think about per-flat savings is to break down your maintenance bill itself. In most housing societies, ~40% of the monthly maintenance charge you pay goes towards CAM electricity costs.

• Let’s assume that you’re paying Rs. 100 in monthly maintenance.
• Around Rs. 40 of that Rs. 100 is going towards the common area electricity bill.
• If a properly sized solar plant offsets the bulk of this CAM electricity cost, that Rs. 40 will be saved.
• Your total maintenance bill could come down to ~Rs. 60.

To make things even simpler, here’s a snapshot of housing societies where Shree Rudra Power Systems installed rooftop solar systems, along with the savings they have generated to date.

What are the Different Financing Options to Install Solar for Apartment Complexes?

There are two main options for financing solar for apartment complexes, and they differ based on who owns the plant, when the savings begin, and how the money flows. The right choice between these two models, CAPEX or OPEX/RESCO, depends on whether your society has the upfront capital available and how soon residents want to see the savings.

• CAPEX financing model: Your society funds the plant upfront through the CORPUS funds. As soon as the plant is commissioned and goes live, 80-90% savings start appearing on the common-area electricity bill. Since the society owns the asset from day one, the benefit reaches residents from month one itself.
• OPEX or RESCO: A third-party installs and owns the plant. So, your society doesn’t pay upfront. However, true savings only kick in after the plant ownership is transferred to your society at the end of the contract, which could be 5-15 years. When your society does not own the plant, you purchase solar electricity from the current plant owner at pre-decided rates that are cheaper than what you pay for grid power.

You can read more about these financing schemes in our blog on CAPEX vs RESCO Solar Financing: Which One Should You Choose?

What are the Benefits of Using Solar Electricity for Common Areas?

Using solar electricity for common areas in a housing society has multiple financial and environmental advantages that every RWA and flat owner must know.

• Lower CAM bills every month: This is the most direct and most visible benefit. Your common-area electricity bill drops significantly, the savings flow into the CAM account, and every resident sees a lower maintenance charge each month. Over a 25-year plant life, the cumulative savings are substantial.
• Protection from future tariff hikes: Electricity tariffs in India increase by 3-6% every year. A society on grid power has no control over these hikes and absorbs them fully through its CAM bill. With solar, you generate a large share of your own electricity and stay insulated from these future increases.
• A green, low-carbon society: A common area solar plant offsets a measurable amount of CO2 emissions every year. For societies that care about their environmental footprint, this is a tangible step. For instance, if your society installs a 100 kW solar system today, this will be equivalent to planting 3,920 trees. Speaking about carbon offset, a 100 kW solar system will offset ~26 lakh kg of carbon dioxide over its 25-year lifespan.
• A property value boost: Properties in societies with rooftop solar are attractive to buyers and tenants who pay attention to running costs. Lower maintenance charges and a green building tag both contribute to better resale and rental value over time.

Conclusion

Installing common area solar is the most practical, lowest-friction, and highest-impact entry point for any housing society looking to cut costs and go green. The loads are predictable, the daytime generation matches daytime consumption, the rooftop is already a common asset, and the savings stay within the society.

The managing committee can choose to pass savings to residents through lower CAM charges or redirect them into the CORPUS fund for repairs, upgrades, and future needs. Either way, the benefit from solar for apartment complexes belongs to all residents collectively.

FAQs

Do solar panels make rooftop space unusable?

Not at all. Modern mounting solutions include elevated structures in which the panels sit above the terrace surface, leaving the space below usable. Your society can still use the terrace for gatherings, functions, walking areas, or even a terrace garden. A site survey will confirm what’s possible for your specific rooftop.

Can solar power run lifts during a power cut?

If it’s an on-grid solar system, then no. On-grid solar cannot run lifts during a power cut because it’s designed to shut down when the grid goes off. This is a safety feature known as anti-islanding, which is implemented to protect line workers. To keep lifts running during outages, your society can either use a diesel generator for backup, which is what most societies do, or install a hybrid solar system with battery storage if the power cuts are prolonged and very frequent.

Will solar fully replace the common area electricity bill?

Well-designed solar for common areas in societies can lower the common area electricity bills by up to 90%.

What approvals does an RWA need before installing solar for common areas?

Your society needs an AGM approval authorizing the installation. Also, terrace roof rights need to be clear, which usually means your society has formally taken over the building from the builder, and the rooftop is in the society’s name. DISCOM approval for net metering is also required for an on-grid system.

How much solar capacity does a housing society need to cover common area loads? 

The solar capacity a housing society needs depends on its actual common area electricity consumption, including lifts, water pumps, lighting, clubhouses, and other shared facilities. As a broad guideline, small societies (up to 50 flats) may need up to 20 kW, medium societies (50-150 flats) may require 10-50 kW, while larger societies often need 100 kW or more. An energy audit of the common-area meter is the best way to determine the appropriate system size for your society.

Is AGM approval mandatory before a housing society installs solar for common areas? 

Yes, an AGM approval is mandatory. The rooftop is a common asset owned collectively by all residents, and any installation on it requires a formal resolution from the society. Without this approval, the installation doesn’t have a legal basis and your society cannot enter into a contract with an EPC partner.

The post Common Area Solar for Societies: Lighting, Pumps and Lifts on Solar appeared first on Rooftop Solar for your home and more | Shree Rudra Power Systems.

Although rooftop solar for apartment buildings can be installed, an individual flat owner cannot install rooftop solar for personal use unless every flat owner and society collectively allow it. Still, hundreds of societies across Mumbai, Pune, Bengaluru, Delhi and many other cities have gone solar and cut their common-area bills by more than 50-60%.

Whether or not you can get the best solar panels for apartments in your society depends on various factors, such as roof rights, RWA approval, DISCOM clearance, the right apartment solar system and metering model, a shadow-free roof area, and a cost-sharing plan.

This guide takes you through all the technical and legal checks that every RWA must know to secure permission to install solar panels for apartments.

Can Apartments Install Rooftop Solar in India?

Yes, apartments can install rooftop solar in India, and a growing number of housing societies are doing it every month.

The most common way to have solar power for apartments is to install a single shared rooftop plant that powers common-area loads such as lifts, water pumps, basement ventilation, corridor lighting, and clubhouse equipment.

Individual flats can also receive credits through virtual net metering (VNM), in which a single shared community solar plant feeds multiple meters in a pre-agreed ratio.

The only thing that is not legally feasible is a single resident installing a private system on the shared terrace without the society’s consent. The terrace is common property, and any rooftop project requires formal approval from every flat owner in the society before the DISCOM application can proceed.

Why Is Solar Adoption in Apartment Buildings More Complex Than in Independent Homes?

Independent homeowners decide whether to go solar on their own. On the contrary, an apartment society must align multiple parties before a shared solar system can be installed.

These are the biggest reasons why it’s so complex to get permission to install apartment rooftop solar in a housing society:

• Shared rooftop ownership: The terrace is a common area held for all flat owners, not the private property of the top-floor flat. No single flat owner can lawfully install an apartment solar system on the common terrace for their own use unless every other flat owner in the society permits it.
• Multiple electricity meters: A society has a common-area meter for lifts, pumps, and lighting, as well as a separate meter for every flat. The metering model chosen at the start of the project determines how generated solar power is allocated and who saves (and how much) on their bill.
• Collective decision-making: A society needs an AGM approval for the scope, budget, financing model, and vendor selection criteria to go solar. In a newly handed-over building where the society has not yet been formed, authority usually lies with the builder. In such cases, a written NOC from the builder is required.
• DISCOM and state policy differences: Net metering, group net metering, and virtual net metering rules for housing societies vary by state and have been changing through 2025 and 2026. Maharashtra, for instance, now formally permits virtual net metering for multi-storied buildings within the same DISCOM area under the MERC 2024 amendment. Karnataka has issued a KERC order allowing apartment associations to use rooftop and elevated structures to install solar. Simply put, the state rule decides what is possible before any technical work begins.

What Must Be Checked for Technical Feasibility Before Installing Solar Panels for Apartments?

The purpose of a technical feasibility check is to confirm whether your building can safely install the solar system your society has in mind and to identify any constraints that could reshape the design before money is committed. Skipping it tends to surface as a problem later, either during installation or after commissioning.

The technical feasibility check falls within the scope of the EPC vendor/installation company your society shortlists, and a good vendor will share the findings transparently with the managing committee before preparing a final quotation.

Here are the different technical feasibility checks your society should expect.

#1. Shadow-free Rooftop Area Analysis

The engineering and design team of the vendor handles the rooftop inspection. This step identifies the actual usable shadow-free area on the roof. Societies with ample shadow-free space can opt for cheaper Mono-PERC bifacial panels, while societies with limited space benefit more from higher-efficiency TOPCon panels.

Here is how the shadow analysis is carried out:

• A 3D model of the terrace and surroundings is prepared, including adjacent towers, trees, and taller structures.
• A sun path simulation is performed across all seasons to identify zones that remain shadow-free.
• On-roof shadow sources are considered, including water tanks, lift machine rooms, stair-heads, parapets, and antennas.
• Adjacent buildings and tall trees are mapped for shifting shadow patterns.
• A map of usable, shadow-free zones is created rather than the total roof area.

#2. Roof Strength and Structural Safety Analysis

This technical feasibility step determines whether the system your society has in mind can actually be installed on the terrace, or whether the size must be reduced to a load the slab can safely carry for the next 25 years.

Here is how the structural assessment is carried out:

• The building architecture review is done, including slab type, structural layout, and existing load paths.
• Building age and slab condition are considered, with a full audit for very old buildings.
• Existing loads on the terrace are considered, including water tanks, antennas, and any prior installations.
• System weight is distributed across the slab to avoid unsafe load concentration at a single spot.
• Wind load assessment is done based on the building’s height and the local wind zone.

#3. Inverter and Electrical Room Planning

The project management team of the vendor handles inverter placement. The decision has a direct impact on both cost and long-term performance. The further the inverter is kept from the society’s main electrical panel, the longer the cable runs, and the more power is lost as heat in transmission.

A well-chosen inverter location lowers both upfront cabling cost and lifetime generation losses.

Here is how the inverter location is decided:

• The society layout is studied end-to-end to map all cable routing options.
• The closest proximity to the main electrical panel is chosen for lower transmission losses.
• Ventilation and security are important, as inverters generate heat and require a protected, accessible space.
• Common areas chosen for the inverter include a ground-floor electrical room or a dedicated terrace room.

#4. Analysis of Electrical Infrastructure Inside the Building

This check, if overlooked until installation day, can cause unprecedented delays. Older buildings with aging wiring or undersized distribution boards may require an electrical upgrade before solar can be installed safely.

Here is what the electrical infrastructure check covers:

• The main electrical panel and distribution boards are inspected for condition and capacity.
• Dedicated AC and DC cabling routes are planned from the rooftop to the main panel.
• Protection equipment must be in place, including MCBs, isolators, and surge protection devices.
• Cable routing is planned to meet fire safety norms and conduit standards.
• An electrical audit may also be recommended for older buildings before solar is integrated.

Legal and Approval Requirements for Apartment Rooftop Solar

The purpose of the legal and approval work is to give your society the formal authority to use the terrace, install the system, and connect it to the grid. Most stalled society projects have issues such as missing documents and pending approvals.

The legal work is owned by the managing committee, with the vendor handling the DISCOM-side filings.

Here are the legal and regulatory requirements your society needs to plan for:

• RWA or apartment association approval: The AGM resolution is the main document for the entire project. It must cover the project scope, system size, budget, and source of funds, solar financing model. and even the vendor selection criteria. A signed copy of the resolution is needed at multiple later stages. Therefore, the AGM has to be planned carefully rather than rushed.
• Builder or developer NOC: In newly handed-over societies and pre-conveyance buildings, the builder still controls the terrace until the common area is formally transferred. In such cases, a written NOC from the builder serves in place of a society resolution.
• Common-area usage rights: A single flat owner cannot install panels on the shared terrace unless every other flat owner approves, as the terrace is common property of all members. Society-owned shared solar systems are the standard route for most apartments to go solar easily.
• DISCOM approval: This is the one universally required external permit, without which a grid-tied PV system cannot be lawfully operated. The DISCOM’s feasibility approval checks whether the local transformer can handle solar export. The DISCOM officials conduct the inspection, after which a bidirectional meter is installed, and the commissioning certificate is issued to the society.
• Fire, safety, and building compliance: A grid-tied solar system has to meet specific safety standards covering cable routing, conduit specifications, emergency access on the terrace, walkway clearance around arrays, system earthing, lightning protection at the highest point of the building, and inverter isolation. These are usually checked during the DISCOM inspection before commissioning.

Which is the Best Apartment Solar Model for Your Housing Society?

The metering model your society chooses decides who actually gets the savings from solar and on which bill. Pick the wrong one, and residents may wonder why their personal bills haven’t changed even though the rooftop is generating power.

Here are four options. The right one depends on your society’s meter structure, available rooftop area, and your state’s net metering rules.

• Society rooftop solar for common loads: Solar energy for apartments is generated by a single plant on the rooftop, which feeds power directly into the society’s common-area meter. The generated power offsets the bill for lifts, pumps, lobby lighting, and other shared utilities. The savings appear as lower monthly maintenance charges for each resident.
• Group net metering (GNM): This shared solar system model is useful when your society has multiple electricity connections. For example, one meter per wing, or for separate amenities such as the clubhouse and security cabin. Surplus generated on one connection is credited to the other connections owned by the society. Thus, a single solar plant can offset multiple society bills.
• Virtual net metering (VNM): One shared plant, mostly on the DISCOM premises, generates solar energy for apartments that have agreed to the model. The credits are split across individual flat meters in a ratio agreed by the society and recorded with the DISCOM. Every flat saves directly on its own electricity bill. This model works well when the society wants residents to benefit personally rather than only through lower maintenance charges.
• Individual rooftop allocation: A portion of the terrace is allocated to specific flat owners who fund and own their own systems, connected to their individual meters. This is the least common of all apartment solar solutions because obtaining permission from the entire society to use the terrace for personal use is rare.

Step-by-Step Process for Solar Installation for Apartments

Here’s a snapshot of the end-to-end steps that usually go into solar installation for apartments in India:

• Step 1 – Get your AGM approval for rooftop solar installation: The resolution must cover scope, budget, financing model, vendor criteria, and signing authority.
• Step 2 – Shortlist two or three vendors: Check registered vendors on the PM Surya Ghar Muft Bijli Yojana National portal for how many installations the vendor has completed in your area.
• Step 3 – Share your Common Area Maintenance (CAM) bills with the chosen vendor: This lets the vendor predict your society’s consumption pattern and propose a system size that matches the actual load profile rather than the roof area.
• Step 4 – The vendors conduct a detailed engineering visit: Rooftop marking and on-site video recording are performed to develop the 3D design of the system. This visit is where shading, structural feasibility, and inverter placement get assessed in person.
• Step 5 – The design team prepares the system design: Shadows from on-roof structures and adjacent buildings are factored in, the solar array layout is fixed, and cable routing is finalized.
• Step 6 – Each vendor presents the proposal: Structure type, inverter and panel brands, wiring approach, PM Surya Ghar Muft Bijli Yojana subsidy process, and a detailed quotation are all covered.
• Step 7 – Society representatives visit a reference installation: A site visit to one of the vendor’s older installations, ideally 18 to 24 months old, is the best way to see how a system actually performs and is maintained over time.
• Step 8 – Select your vendor accordingly: Picking the vendor with the lowest quote isn’t the smartest strategy. Instead, prepare an RFQ (Request for Quotation) and score each vendor on a few clear parameters – brand’s experience and how many installations they have done in your area, the solar technology they are offering, the financing options they bring, whether or not they offer a savings guarantee, the warranty/guarantee they offer for solar components, and the price they’re offering.
• Step 9 – Installation happens within ~45-60 days: The mounting structure is installed, panels are placed, and the meter connection is made, but the system is not yet live on the grid.
• Step 10 – Liaisoning team contacts the DISCOM: The team collects the documents required for the subsidy application from your society. This phase usually takes about 2 months.
• Step 11 – Subsidy disbursal: Disbursal of the PM Surya Ghar subsidy takes 2-6 months after the system goes live, depending on state processing.

Documentation Required for Apartment Rooftop Solar Installation

Here are the common documents that are required for apartment rooftop solar installation:

• Common-area electricity bill for at least the last 6 months.
• Occupancy certificate confirming the society is registered and fit for occupancy.
• Terrace roof rights documentation.
• PAN card of the housing society.
• AGM resolution copy and society registration certificate.
• Builder NOC where the society is not yet formed.

Technical Checklist Before Signing a Solar Vendor Contract

Use this checklist during the proposal review. A vendor who cannot answer any of these is a vendor to drop.

• Panel wattage and warranty: Confirm both the product warranty and the 25-year performance warranty.
• Inverter warranty: Standard cover plus extended cover, since the inverter is the most important solar component.
• ALMM and DCR compliance: Panels must be on the approved lists, since non-compliant modules do not qualify for the PM Surya Ghar subsidy.
• Mounting structure material: Verify the galvanization grade and base plate thickness. For instance, Shree Rudra Power Systems’s Windopro mount has an 80-micron HDGI (hot-dipped galvanized iron) coating. Even with a 3-micron yearly erosion rate, the structural integrity stays intact for 25+ years.
• Wind-load design: Confirmed for the building’s specific height and local wind zone.
• Waterproofing responsibility: Confirm who seals penetrations and whether HILTI airtight sealing is used to fill drilling gaps to prevent water seepage.
• Earthing and lightning protection: A lightning arrester should be placed at the highest point of the building, with proper system earthing.
• Generation estimate: Annual kWh, the performance ratio guarantee, and the shortfall remedy should be written into the contract.
• AMC terms: Cleaning frequency, fault response time, and the remedy if generation drops below the guarantee should be specified.
• Monitoring dashboard: Real-time generation visibility with alerts and historical reporting should be provided.
• Net metering support: Vendor files and follows up on the DISCOM application end-to-end.
• Subsidy support: The vendor must handle the PM Surya Ghar application, documentation, and disbursal follow-up.
• Post-installation documentation: Test certificates, warranty cards, and the commissioning certificate should be handed over after installation.

Legal Checklist for RWAs and Apartment Associations

The legal side has its own checklist. The committee owns most of it, and the vendor only supports.

• Society registration documents: The registration certificate should be ready before the DISCOM application is filed.
• Committee resolution: A resolution approving the project, the budget, and the signing authority should be formally recorded.
• Member consent or AGM approval: A written record of the meeting at which the project was approved should be prepared and shared with all residents, and the meeting must have had sufficient members present for the decision to be valid.
• Terrace usage authorization: The resolution should specifically authorize the use of the common terrace for the solar installation.
• Common meter details: Sanctioned load, account number, and the last 6 months of bills should be provided to the vendor.
• Vendor agreement: A signed contract should cover the scope of work, payment terms, warranties, and liability allocation.
• Payment approval: The committee meeting record should clearly state which members are authorised to sign cheques or approve bank transfers for the solar project.
• DISCOM application authorization: A signed authorization should allow the vendor to file the net metering application on the society’s behalf.
• Subsidy application documents: The society PAN, a cancelled cheque, and bank details matching the registered society name should be ready.
• Maintenance responsibility: The contract should specify who is responsible for cleaning, AMC, and post-warranty service, and at what cost.
• Insurance clause: The contract should state whether the system is insured, who pays the premium, and what is covered.
• Asset ownership clause: Under a RESCO financing arrangement, the transfer terms and asset condition at handover should be written into the contract.

What are the Benefits of Installing Solar Panels in Apartments in India?

Installing solar panels in apartments helps housing societies cut recurring electricity costs, use their shared rooftop more productively, and give residents a long-term energy solution. Since common-area electricity covers lifts, pumps, corridor lights, clubhouse equipment, and other shared facilities, even one well-sized rooftop solar system can create a good amount of savings for the entire society.

• Lower common-area electricity bills: Solar can offset power used by lifts, pumps, lobby lights, basement ventilation, and other shared loads.
• Reduced maintenance charges: When the society’s common electricity bill drops, residents can benefit through lower monthly maintenance costs.
• Direct savings for flats through VNM: In states that allow virtual net metering, solar credits can be split across individual flat meters.
• Better use of shared rooftop space: The common terrace can become a productive asset instead of staying unused.
• Protection from rising tariffs: Solar helps societies depend less on grid electricity, which reduces the impact of future power price hikes.
• Cleaner energy for the community: Apartment solar systems reduce dependence on conventional electricity and support greener living.
• Long-term financial value: A properly designed PV system can generate savings for 25 years or more with regular maintenance.
• Savings can fund society upgrades: The money saved on electricity can be used for improvements such as CCTV, gym equipment, play areas, or building repairs.

Conclusion

The technical and legal sides of solar for apartment buildings move on parallel tracks. A project gets commissioned on time only when both are complete.

• The technical work covers shadow-free area, structural safety, inverter placement, and electrical checks inside the building.
• The legal work covers AGM approval, builder NOC for terraces that have not yet been transferred, DISCOM clearance, and a metering model that complies with the state’s current rules.

FAQs

Is solar worth it for apartment buildings in India?

Yes, rooftop solar for apartment buildings is a highly beneficial investment. Electricity is around 40% of a society’s recurring expenses. A rooftop system can easily offset common-area consumption, and the savings can either reduce monthly maintenance costs or fund upgrades such as CCTV, a gym, or a play area. Returns are usually 3 to 10 times higher than investing the same money in a fixed deposit.

Can an individual flat owner install solar on the shared terrace?

This is not possible without the consent of every flat owner in the society. The terrace is common property held in common by all members. The most common route to go solar for a society is a society-owned shared solar system that either generates power for common areas or a common solar system in the DISCOM premises that allocates credits to flats through virtual net metering, where the state permits it.

Can apartment solar reduce individual electricity bills?

Yes, this is possible through virtual net metering (VNM). Under a VNM arrangement, one shared solar system generates credits that are allocated across individual flat meters in a ratio agreed by the society and recorded with the DISCOM. As a result, each flat sees a direct saving on its own bill. Where only net metering is available, the savings show up in lower society maintenance charges instead.

Do I need society or RWA approval to install solar on the terrace?

Yes, this is mandatory. An AGM or committee resolution is required before any DISCOM application can be filed. The resolution must approve the scope, budget, financing model, vendor selection criteria, and signing authority. In societies that are not yet formed or are pre-conveyance, a written NOC from the builder takes the place of the resolution.

The hardest question for businesses is which solar business model to choose, because the solar investment model you adopt today determines who owns the asset, who bears the risk, and how much you actually save over 25 years.

Currently, there are two dominant solar business models in India:

• CAPEX solar model: Here, your business buys and owns the plant from day one.
• RESCO model: Here, a third party owns the plant and sells you the power.

Simply put, the difference between RESCO vs CAPEX is plant ownership. Under CAPEX, you own the asset and keep all the savings. Under RESCO, you own nothing and pay a fixed per-unit rate that is lower than your grid tariff.

Neither solar investment model wins automatically for every business profile.

• The CAPEX solar model is better for businesses with lots of capital or loan access that want asset ownership, accelerated depreciation benefits, and the lowest cost over the full plant life.
• The RESCO model suits businesses that want negligible upfront investment and no maintenance responsibility in exchange for not owning the system from day 1 and committing to a long PPA.

This guide takes you through the full scope of RESCO vs CAPEX solar models for financing commercial solar panel systems, including their cost-to-benefit ratios, pros and cons, and the factors to consider when choosing the model that fits your business needs and cash profile.

What Is the CAPEX Solar Model?

Under the CAPEX solar model, your business pays for the solar plant and owns it. The money comes from either your own funds or a solar loan. From the day the plant is commissioned, every unit it generates belongs to you.

Simply put, in the CAPEX solar model, you spend once, maintain the asset, and it keeps producing value for years after it has paid for itself.

Key Features of the CAPEX Solar Model 

Here’s a snapshot of the key features of the CAPEX solar business model in India:

• Upfront investment: You fund the full project cost at the start, either directly or through financing, and the plant is yours from commissioning.
• Business owns the asset: The rooftop solar system is your asset throughout its operational life of 25 years.
• Higher long-term savings: Once the payback period ends, the electricity is close to free, except for routine upkeep.
• Eligible for accelerated depreciation benefits: Because you own the asset, your business can claim up to 40% accelerated depreciation, which improves the return further.
• Full control over vendor, equipment, and maintenance: You pick the EPC partner, the inverter and panel brands, and how the plant is serviced. Therefore, the quality stays in your hands.

Cost-to-Benefit Ratio from CAPEX Solar Model

To give you a feel for the lifetime savings and payback from the CAPEX solar investment model, here are actual numbers from a 100 kW commercial rooftop solar plant. The example is a mid-sized commercial unit in a Maharashtra or Gujarat industrial zone, and the figures below show what ownership earns over the plant’s life.

• Solar system size: 100 kW
• Rooftop space required: ~9,000 to 10,000 sq. ft.
• Monthly electricity consumption: 14,000 to 16,000 units
• Grid tariff: Rs. 10.5 per unit
• Annual solar generation: ~1.45 lakh units
• Plant life: 25 years

Here is the full cost and benefit picture for this plant under the CAPEX solar model:

DISCLAIMER: The figures mentioned above are illustrative estimates for a 100 kW commercial rooftop solar system. Actual costs, tariffs, and savings vary with location, city, system size, system technology, vendor pricing, and prevailing policy, etc.

As you can see from the table above, the plant pays for itself in ~3.1 years, which gives a practical payback range of 3 to 4 years. Even after you account for yearly solar panel degradation and an inverter replacement around Year 12 to 15, the long-term returns stay very strong.

How Can a CAPEX Solar Loan Help?

Many businesses walk away from the CAPEX solar model because they assume it means writing a single large cheque on day one. That assumption is outdated. Most commercial rooftop solar projects today are financed through banks and NBFCs, which changes the math completely.

Under a solar loan structure, the ownership and control stay with you while the capital pressure eases.

• The business owns the solar plant: Financing does not change ownership, so depreciation and full savings still belong to you.
• The lender finances 70% to 90% of the project cost: You bring in only a small share of the total upfront.
• Repayment happens through EMIs over 3 to 7 years: The cost is spread over the years rather than charged in a lump sum.
• Monthly electricity savings often offset a large part of the EMI: The plant helps pay for itself while you are still repaying the loan.

Here is how that looks for the same 100 kW project from above:

DISCLAIMER: For the monthly electricity savings, we have considered the 100 kW plant generating ~12,000 units a month and a grid tariff of Rs. 10.5 per unit, which works out to ~Rs. 1.25 lakh saved every month. For the monthly EMI, we have assumed a Rs. 35 lakh loan over 5 years at the kind of interest rates commercial solar loans usually carry. Your actual savings and EMI will change with the interest rate, loan tenure, real generation, and state tariff. So, treat these as indicative numbers only.

As you can see from the table above, even during the loan period, the business generates positive monthly cash flow, since the Rs. 1.25 lakh in savings covers the Rs. 80,000 EMI while still leaving savings. After the loan is repaid, the solar power becomes far cheaper for the remaining 2 decades of the plant’s life.

What Is the RESCO Model (OPEX-PPA) in Solar Rooftop Business? 

Under the RESCO model, also known as the OPEX solar model, you do not buy the plant. A third-party developer installs and owns the solar system and sells your business the electricity the plant produces at an agreed rate, well below your grid tariff.

Since you have to sign a long-term power purchase agreement (PPA) with the third-party installing the plant, this model is also known as the solar PPA model. The PPA runs for 5 to 25 years, depending on the terms, and during that period, you pay for the solar electricity units you consume.

The investor behind the plant is either an HNI or a financing partner seeking stable, long-term returns.

Key Features of the RESCO Solar Model 

Here’s a snapshot of the key features of the RESCO/OPEX solar model in India:

• Low upfront investment: The business usually has to make a deposit of 10%. As a result, your out-of-pocket capital investment stays minimal.
• Third-party ownership of the solar asset: The developer owns the plant for the duration of the solar PPA model.
• Pay-per-unit electricity pricing: You pay only for the solar power you actually consume, billed per unit. A close cousin to this is the solar lease model, where you pay a fixed monthly amount rather than per unit generated. However, it should not be confused with RESCO, as the two are different.
• Long-term solar PPA agreement: After the PPA term ends, the plant is usually transferred to the customer, though this depends on the contract and is not guaranteed in every case.
• Operations and maintenance handled by the RESCO investor: Servicing, monitoring, and repairs are the developer’s responsibility.
• Predictable electricity costs: Your solar tariff is fixed and below grid rates, which protects you from rising power prices.
• Lower financial and operational risk: With no large assets to fund or maintain, the developer bears the capital risk and maintenance costs, not your business.

Cost-to-Benefit Ratio from the RESCO Model

To show the RESCO numbers fairly, we have used the same 100 kW plant details as used for the CAPEX example. The plant, consumption, and generation stay identical. What changes is that the developer owns the system, and the business pays a fixed PPA tariff instead of funding anything.

• Solar system size: 100 kW (developer-owned)
• Annual solar generation: ~1.45 lakh units
• Existing grid tariff: Rs. 10.5 per unit
• RESCO solar tariff: Rs. 6.8 per unit
• PPA term: 20 to 25 years

Here is the cost and benefit picture for the business under the RESCO model.

DISCLAIMER: For the annual savings, we have considered a RESCO solar tariff of Rs. 6.8 per unit against a grid tariff of Rs. 10.5 per unit, which gives a saving of Rs. 3.7 on every unit. Applied to the same 100 kW plant generating around 1.45 lakh units a year, that comes to ~Rs. 5.4 lakh saved annually. Your actual savings, however, will change with the PPA tariff your developer offers, any yearly tariff escalation in the contract, the system size, and your state grid rate. So, treat the figures in the table as indicative only.

The savings start in the first month in the RESCO model, but they remain capped by the PPA rate for the full contract term. That’s the real trade-off for paying nothing up front. There is no large outlay to recover, so the small deposit is earned back within 1 to 3 years.

RESCO vs CAPEX: Quick Comparison Table 

Now, let’s compare RESCO and CAPEX models side-by-side for clarity. To give a fair evaluation, we have used the same numbers from a 100 kW commercial solar system, which has been used unanimously throughout this blog.

Benefits of CAPEX Solar Model for Businesses

CAPEX solar model wins on what ownership earns you over the full life of the plant rather than what it costs on day one. Here are the main advantages of this solar business model that you must know.

• Maximum savings after payback: Once the 3 to 4 year payback ends, the savings you make each year are pure gain for the remaining 2 decades.
• Ownership of a 25-year asset: The plant stays an owned asset on your books for its full life.
• Protection from rising grid tariffs: Every unit the plant generates for you shields you from the annual grid tariff hikes.
• Tax benefits such as accelerated depreciation: Eligible businesses can claim accelerated depreciation of up to 40% on the asset, thereby lowering taxable income and shortening the effective payback period.
• Better control over plant quality and vendor selection: You choose the solar components and the vendor. Therefore, generation and reliability stay in your control.

Limitations of the CAPEX Solar Model for Businesses 

Ownership comes with responsibilities that not every business is set up to carry. These are the real disadvantages of the CAPEX solar model.

• High upfront investment: Even with financing, you commit capital and a repayment obligation that a leaner business may not want.
• O&M responsibility: Cleaning, monitoring, and repairs are the plant owner’s responsibility, which can be handled in-house or through a managed contract.
• Longer internal approval cycle: A capital purchase of this size requires board or management sign-off, which slows the decision-making process.

Benefits of the RESCO Model for Businesses 

The RESCO model wins on speed, affordability, and simplicity. You get solar savings without funding or running anything. Here are the key advantages of the RESCO model that you must know.

• Minimal upfront investment: A small security deposit of just 10% of the entire project cost.
• Immediate electricity bill savings: You save money on power as the solar electricity you purchase in a solar PPA model is at rates lower than the grid tariffs.
• O&M handled by the investor: Maintenance, monitoring, and plant performance guarantee are the developer’s headaches in the RESCO model.
• Better for multi-site or capital-light businesses: Companies operating in multiple locations can go solar without tying up significant capital at each site.
• Predictable solar tariff through the PPA: Your per-unit rate is locked for the contract term, which makes budgeting straightforward while grid rates keep climbing.

Limitations of the RESCO Solar Investment Model for Businesses 

Here’s a snapshot of the main disadvantages of the solar PPA model:

• Lower lifetime savings than CAPEX: You never reach the near-free power that the CAPEX solar business model delivers after payback.
• Long-term PPA commitment: You are tied to the developer for years, which limits flexibility if your plans change.
• Exit clauses can be restrictive: Leaving the contract early or relocating can trigger penalties that are easy to miss at signing.
• Contract terms matter as much as the tariff: A low per-unit rate looks great on paper, but it means little if the contract raises that rate every year or makes leaving early expensive. The escalation clause, buyout terms, and exit conditions decide your real savings in the RESCO model.

Which Model Gives Better Long-Term Savings: CAPEX or RESCO? 

Over the full 25-year lifespan of the solar system, CAPEX gives higher total savings, and the gap is wide. In the example we’ve used in this blog, the CAPEX model saves ~Rs. 3.2 to 3.8 crore across the 25-year lifespan of a 100 kW solar system because you keep every unit generated after the payback period.

RESCO, on the other hand, saves a steady but smaller amount each year, capped by the PPA tariff, since the developer takes a margin for owning and running the plant.

Simply put, RESCO wins on early cash flow while CAPEX wins on lifetime value.

Which Model Is Better for MSMEs? 

For MSMEs, the answer depends on capital and tax position.

• When to choose CAPEX: An MSME that is profitable, owns its premises, and can access a solar loan does best with CAPEX, since the accelerated depreciation and full savings strengthen the balance sheet.
• When to choose RESCO: An MSME that is short on capital, operates from rented premises, or wants zero operational involvement fits the RESCO model better, because it gets immediate savings without locking up funds the business might already be short on.

Which Model Is Better for Large Commercial and Industrial Businesses? 

Large C&I businesses with capital and high daytime load usually prefer CAPEX for the depreciation benefit and the lowest long-term cost per unit. However, a business that wants to preserve capital for its core operations, or one expanding across multiple sites, tends to lean toward RESCO to keep solar off the balance sheet while still cutting power bills from day one.

Important Things Businesses Should Check Before Choosing the CAPEX Solar Model

Here’s a practical checklist to consider before you choose the CAPEX solar investment model:

• Total upfront investment required: Confirm the full project cost and how much you fund directly vs through a loan.
• Expected payback period: For a well-sized commercial rooftop solar system, this is between 3 and 4 years.
• Roof condition and available space: The roof must take the structural load and offer the area the system needs, ~9,000 to 10,000 sq. ft. for a 100 kW plant.
• Solar system quality and EPC vendor selection: Generation over 25 years depends heavily on component quality and a reliable solar partner.
• Operations and maintenance costs: Budget for cleaning, monitoring, and an eventual inverter replacement to keep the ownership math realistic.

Important Things Businesses Should Check Before Choosing the RESCO Model

Here’s a checklist of what you should consider when planning to go ahead with the RESCO solar business model:

• Contract duration and lock-in period: Know exactly how long you are committed and what flexibility, if any, you retain.
• Electricity tariff and annual price escalation: Check the starting rate and any yearly escalation, since a rising tariff erodes your savings over time.
• Expected payback period: Because your share is only a small deposit, the payback period is short, i.e., 1 to 3 years.
• Maintenance and downtime responsibility: Ensure the PPA clearly assigns O&M responsibilities to the developer throughout the PPA’s tenure.
• Exit or early termination penalties: Understand the cost of leaving early or relocating before you sign, not after.
• Ownership terms after the agreement ends: Confirm whether the plant transfers to you at the end of the term and on what terms, as this varies by contract.

Conclusion

You cannot simply pick RESCO vs CAPEX based on a single factor. The solar investment model you choose must align with your business’s cash flow and whether you prefer higher savings over time or a lower upfront investment.

CAPEX solar model offers the highest lifetime savings. The RESCO model, on the other hand, is a great option for businesses that value cash flow, flexibility, and a hands-off setup with immediate savings and no upfront burden.

Whichever solar investment model you choose, the plant still has to be designed and installed well. Thus, picking a strong EPC or RESCO partner matters as much as picking the model.

If you are still weighing the two, work through this quick decision path.

• Do you own your premises? If not, RESCO is usually the practical choice, or you negotiate with your landlord for a CAPEX setup.
• If so, do you have capital or access to loans? If yes, go with CAPEX for maximum ownership and savings.
• If yes to premises but no to capital? RESCO lets you go solar now and save from month one without funding the plant.

FAQs

Which is cheaper: RESCO or CAPEX? 

CAPEX solar model is cheaper over the full project lifecycle because the business owns the asset and keeps all the savings after a short payback period of 3-4 years. RESCO, on the other hand, costs less upfront but more over the long run, since the developer’s margin is built into the tariff.

Which model gives better ROI? 

The CAPEX solar model tends to offer a better long-term ROI, thanks to ownership, full savings, and depreciation benefits that you will receive. RESCO, on the other hand, offers faster short-term cash flow benefits because savings begin immediately with almost no investment.

Can businesses claim depreciation under RESCO?

No. Under the RESCO model, the developer owns the asset. Therefore, the depreciation benefit stays with the developer rather than your business.

Does RESCO affect my balance sheet?

Usually, it does not, because you do not buy/own the solar system. The payments are treated as an operating expense. This off-balance-sheet treatment is one of the main reasons capital-light businesses prefer the RESCO financing model.

Who is responsible if panels underperform under RESCO?

The RESCO developer is responsible for the performance under the PPA. Even maintenance falls under the developer’s scope throughout the PPA.

Can I switch from RESCO to CAPEX later? 

Some agreements allow a buyout after a few years, which lets you have the plant ownership. Whether this is possible, and at what price, depends entirely on how the contract is structured. Therefore, always check the buyout clause before signing.

Is RESCO the same as OPEX? 

Yes, RESCO and OPEX are the same solar investment models, and are used interchangeably in the Indian solar industry.

What is the difference between RESCO and solar PPA? 

A solar PPA is the agreement used within the RESCO model. In other words, RESCO describes who owns and runs the plant, and the PPA (power purchase agreement) is the agreement that sets your tariff, term, and exit terms.

The Process of Applying for Subsidies for Housing Societies

To avail of the benefits of the PM Surya Ghar Muft Bijli Yojana, follow these steps.

1. Registration and Application

Access the official website of the PM Surya Ghar Muft Bijli Yojana. Provide the necessary details on the portal to create an account for your housing society.

Fill out the rooftop solar panel installation application form, specifying the desired capacity and other relevant information. Then, submit the required documents, including proof of identity, address, electricity bill, and roof ownership certificate.

2. Installation and Commissioning

Once the electricity distribution company (DISCOM) approves the feasibility of the solar installation, choose a registered solar vendor like Shree Rudra Power Systems to install the solar system. Apply for net metering to exchange excess electricity with the grid. Undergo a final inspection by the DISCOM to obtain a commissioning certificate.

3. Claiming the Subsidy

Submit your bank account details and a cancelled cheque using the portal. The subsidy amount will be credited to your bank account within the stipulated timeframe by the government.

Documents and Eligibility for Solar Financing

Arranging financing for solar installation for a society is often a concern due to various factors. Fortunately, there are several flexible and affordable financing options available that make switching to solar energy more accessible without putting undue strain on the Society’s budget.

Financing through Society’s Corpus

Eligibility: Sufficient funds are available in society’s accounts.

What it includes:

Corpus financing involves using the society’s existing funds to finance the solar installation. This could include money from the society’s reserves, sinking funds, or other pooled resources.

How to get it:

The first step is to obtain approval from the society’s members during the AGM (Annual General Meeting). The managing committee must pass a formal resolution authorising the use of society funds for the solar project. Once approved, funds can be allocated from the society’s reserves or sinking fund, ensuring the project is financially supported without external borrowing.

OD Facility from the bank

Eligibility: Good credit history, sufficient cash flow, and collateral (if required).

What it includes:

The OD facility is a great option if the society has a good relationship with the bank and can offer an overdraft loan at a lower interest rate.

How to get it:

Typically, banks require a strong credit history, financial documents, a viable project proposal, and society’s income-expenditure report to assess the economic health and creditworthiness of the society. The society will need to discuss terms such as the overdraft limit and interest rates with the bank.

Shree Rudra Power Systems Financing

Eligibility: Meet basic eligibility criteria set by Shree Rudra Power Systems and be registered under PM Surya Ghar Muft Bijli Yojana.

What it includes:

When you opt for Shree Rudra Power Systems, our Zero Investment Plan makes the process simple and affordable. With flexible EMI options ranging from 6 to 60 months, you can choose a plan that aligns with your budget and financial planning.

How to get it:

In Shree Rudra Power Systems, your initial down payment is reimbursed through the government subsidy, meaning you start with zero out-of-pocket costs. We design your monthly EMIs to match the savings on your electricity bills, ensuring that you are paying nothing extra. Your electricity bill savings offset the EMI payments for a seamless transition.

Before choosing the right financing option, you must get approval from your housing society’s Annual General Meeting (AGM) for installing solar. 

Once you have a reasonable estimate of the level of support from the members, here’s how you can manage achieving the necessary approvals effectively.

Tips to Achieve Approval from the AGM to Install Solar

1. Secure Approval from the AGM

Before the AGM, gauge members’ interest in a solar project to build support. Present a clear proposal at the meeting, detailing costs, benefits, and environmental impact. Address potential objections and highlight long-term gains to gain approval.

2. Form a Solar Committee

Create a committee with members skilled in finance, engineering, and project management. Their role includes researching solar options, liaising with vendors, managing the budget, and overseeing the project.

3. Request Quotations (RFQ)

Issue an RFQ outlining project requirements, system size, timeline, warranty, and maintenance. Evaluate bids based on cost, vendor experience, and product quality.

4. Hire a Solar Advisor

Engage a reputable solar advisor, such as those from Shree Rudra Power Systems, to ensure proper design and implementation. They will serve as liaisons and streamline decision-making.

5. Educate Society Members

Run awareness campaigns to showcase the benefits of solar energy, including cost savings and environmental impact. Use brochures, Q&As, and success stories from other societies to build enthusiasm and keep members informed.

FAQs

Q1. How long does it take to install solar for housing societies?

Ans. Installation of solar systems for housing societies typically takes 12-20 weeks. This includes:

– Planning and approval: 2-4 weeks for site assessment and approvals.

– Installation: 4-6 weeks to fit the system.

– Inspection and commissioning: 4-6 weeks for final checks and activation.

Factors affecting the timeline:

– System size: Larger installations take longer.

– Installation complexity: Roof type and structural issues can delay progress.

– Approval delays: Waiting for permissions and inspections can add time.

Q2. When will the housing society get the solar subsidy?

Ans. The timeline for receiving this subsidy varies, depending on the approval process by the government authorities and their disbursal cycle. You can check your subsidy status through the national portal for rooftop solar.

Q3. How can the housing society apply for solar financing with Shree Rudra Power Systems?

Ans. The criteria to qualify and apply for solar financing with Shree Rudra Power Systems are as follows.

The eligibility criteria for Shree Rudra Power Systems financing include the following:

Documents required include the following:

• PAN CARD of society – Self attested
• KYC of signing authority ( Any 2 Member) – Self attested
• Registration documents – Self-attested
• List of members – Self-attested
• Contact details of signing authority
• Last 12 months’ bank statement
• The last 3 months’ electricity bill
• Last 2 years audited financials
• Quotation

Loan approvals are fast, often within 2-3 days. EMIs commence after the loan is approved.

Q4. When will the breakeven point reach for housing societies?

Ans.  The breakeven point for housing societies investing in solar energy depends on the price per unit charged by the electricity board. 

Formula:

Breakeven Point (years) = Net Cost of Solar Project/Annual Savings

Where:

• Net Cost of Solar Project = The total cost after subsidy.
• Annual Savings = Annual Energy Production (in units) × Rate per Unit of Electricity

Example Calculation:

For a 100 kW system with an average cost of ₹60,000 per kW:

• Net Cost of Solar Project (cost – subsidy) = ₹60,00,000 – ₹18,00,000 = ₹42,00,000
• Rate per Unit of Electricity = ₹10 per unit
• Annual Energy Production = (from the previous example, 100 kW system) ≈100×1400=1,40,000 units/year

Steps:

1. Calculate Annual Savings:
   Annual Savings = 1,40,000×10 = ₹14,00,000
2. Calculate Breakeven Point:
   Breakeven Point (years) = 60,00,000 / 14,00,000 ≈ 4.2 years

This means the housing society would recover the solar installation cost in about 4.2 years from saving on electricity bills.

Q5. What is the maximum subsidy a housing society can avail through PM Surya Ghar Muft Bijli Yojana?

Ans. Housing societies can receive a government subsidy of ₹18,000 per kilowatt, up to ₹90 lakh for a maximum of 500 kilowatts, under the National portal for rooftop solar subsidy.

Q6. Is solar maintenance necessary for housing societies?

Ans. Yes, regular solar maintenance is crucial for optimal performance. Panels can collect dust, debris, and other residues that reduce efficiency.

For example, at Prestige South Ridge in Bangalore, our ongoing maintenance of their 268 kW solar system has consistently exceeded generation targets, resulting in a 10% increase in savings for residents.

Scheduled maintenance, including cleaning and inspections, prevents performance issues, extends the system’s lifespan, and ensures continued energy savings.

Solar Subsidy for Housing Societies in India

While the PM Surya Ghar Muft Bijli Yojana scheme offers significant subsidies to individual homeowners, it also provides substantial financial support to housing societies aiming to adopt solar energy on a larger scale.

Housing societies can benefit from a subsidy of ₹18,000 per kW, applicable for installations up to 500 kW. This applies to all Indian states. This subsidy can reduce the overall cost by up to ₹90 lakhs, making it a game-changer for communities looking to transition to solar power. 

By embracing this opportunity, housing societies can drastically cut their electricity costs, with many expected to achieve full savings within a few years of installation.

Steps to Apply for Solar Subsidy for Housing Society

Applying for the solar subsidy under the PM Surya Ghar Muft Bijli Yojana is straightforward. However, you must partner with a reliable solar vendor, like Shree Rudra Power Systems who can guide your housing society through every step. If you’re a society member eager to see your CHS go solar, choosing the right vendor can make all the difference, ensuring a smooth and successful application. 

Here’s a step-by-step guide to help you navigate the process.

Step 1: Visit the national portal for rooftop solar – PM Surya Ghar Muft Bijli Yojana website. Click on the ‘Apply for Rooftop Solar’ button on the left-hand side of the homepage.

Step 2: Proceed to the ‘Registration’ section. You should select your state, district, and electricity distribution company (DISCOM). Enter your customer account number and click ‘Next’ to continue.

Step 3: Enter your mobile number and email address. Once you’ve entered these details, click ‘Proceed’.

Step 4: Fill out the ‘Apply for Rooftop Solar Installation’ form with the required details. This will include personal information, details about your property, and your electricity connection. Then, upload the necessary documents and click the ‘Final Submission’ button to submit your application.

Step 5: After submitting your application, you will need to wait for feasibility clearance from your DISCOM. This stage is important as it determines whether your house is eligible for solar installation. Once approved, you can proceed with the installation process.

Step 6: With the feasibility approval ready, you can commence solar installation. 

Step 7: After installing the solar plant, submit the plant details through the portal and apply for a net meter. This meter will measure the electricity generated and consumed, allowing you to receive credits for any excess power sent back to the grid.

Step 8: After installing the net meter, your DISCOM will conduct an inspection. Following a successful inspection, they will create a commissioning certificate from the portal, verifying that your solar system is functioning.

Step 9: After getting the commissioning certificate, return to the PM Surya Ghar Muft Bijli Yojana webpage and submit your bank account information and a cancelled cheque. The subsidy will be credited to your bank account within the stipulated timeframe by the government.

How Long Does It Take to Process the Subsidy for Housing Societies?

After filing the subsidy application, the local DISCOM or equivalent agency will typically review and accept it within 2-4 weeks. The subsidy amount is transferred into the society’s bank account within a few weeks after project completion (the step after commissioning).

Since the recent Lok Sabha elections, the government has streamlined the subsidy disbursement process to prevent delays, with faster approvals and digital processing. Depending on local administrative efficiency, most housing societies get subsidies within 2-3 months of applying.

Process for Installing Rooftop Solar for Housing Society

Installing a solar power system is a multi-step process that can vary significantly depending on the vendor. While many local vendors offer basic, non-engineered services, Shree Rudra Power Systems takes a comprehensive and meticulous approach to ensure your solar installation works for the long run. 

Here’s how our process stands apart:

1. Initial consultation and site assessment 

We discuss your energy needs, budget, and other relevant factors. Following this, our solar expert assesses your roof’s orientation, shading, and structural integrity to determine the optimal setup for maximum energy production. Your electricity bills will be analysed to determine the optimal solar system size.

2. Design and planning

Basis the site assessment, the vendor will develop a personalised design for your solar power system. This design includes the layout of the solar panels, the placement of the inverter, the mounting structures, and the connection to your existing electrical system. 

Once you have approved the design and plan, we will prepare the required documentation for the next phase.

3. Approval process

Before starting the installation, we will help you get the necessary permissions from the local government, such as building permits and electrical inspections. The DISCOM will examine the proposal to make sure it meets the rules and then issue the necessary permits. 

We will also help you complete the subsidy application and get the feasibility approval.

4. Installation and commissioning

Usually, the installation consists of putting the solar panels on your roof, installing the inverter, and tying the system to your electric grid. The whole procedure will take less than 8 hours with Shree Rudra Power Systems, unlike other local vendors who will take a few days to finish. 

The system is completely tested to guarantee it runs as intended when the installation is finished. Commissioning marks the last phase when the DISCOM checks the system and produces a commissioning certificate verifying that the system is ready for use.

5. Post-installation support

We offer post-installation assistance through 360-degree maintenance to guarantee your solar power system runs as it should after commissioning. This maintenance includes resolving technical issues, system performance monitoring, and solar panel deep cleaning.

Tips to Achieve Approval from the AGM to Install Solar

One of the most important steps in installing solar power is getting approval from your housing society’s Annual General Meeting (AGM). 

A pro tip: Before the AGM, you can informally gauge the society member’s interest and support for a solar project. 

Once you have a reasonable estimate of the level of support from the members, here’s how you can manage achieving the necessary approvals effectively.

1. Get In-Principle Approval and a Tentative Budget from the AGM

Draft a clear proposal emphasising the approximate cost of going solar including expected installation, maintenance, and other relevant costs, the benefits of solar energy, potential financial savings, and environmental effects. 

A well-prepared plan that addresses possible objections and emphasises long-term benefits will likely get AGM approval.

2. Form a Solar Committee

Build a specialised committee with various talents and interests, including finance, engineering, and project management. The committee’s responsibilities include:

• Studying the available solar options
• Communicating with vendors
• Managing the budget
• Supervising the project from start to finish

Having a dedicated team guarantees that the project is well-coordinated and that decisions are made for the benefit of society.

3. Float a Request for Quotation (RFQ) for Vendor Selection

The RFQ should explicitly state the project requirements, estimated system size, installation timetable, warranty, and maintenance services. While evaluating the quotations, consider cost, vendor experience, product quality, and after-sales service.

4. Hire a Solar Advisor

The right solar advisor will ensure your society’s project is designed and implemented correctly. They will be a valuable liaison between the Solar Committee, and society members, addressing concerns and making decisions more efficiently. Reputed solar vendors like Shree Rudra Power Systems will act as solar advisors to help you through the process.

3. Educate Society Members About Solar

Organise awareness campaigns to inform society members about long-term cost savings, enhanced property value, and the ecological impact of solar energy. Share success experiences from other societies that have implemented solar energy. 

To get everyone on the same page and excited about the project, hand out informative brochures, host Q&As, and keep everyone updated on the progress of this endeavour.

Q3. When will the breakeven point reach for housing societies?

Ans.  The breakeven point for housing societies investing in solar energy depends on the price per unit charged by the electricity board. 

Formula:

Breakeven Point (years) = Net Cost of Solar Project/Annual Savings

Where:

• Net Cost of Solar Project = The total cost after subsidy.
• Annual Savings = Annual Energy Production (in units) × Rate per Unit of Electricity

Example Calculation:

For a 100 kW system with an average cost of ₹60,000 per kW:

• Net Cost of Solar Project = ₹60,00,000 – ₹18,00,000 = ₹42,00,000
• Rate per Unit of Electricity = ₹10 per unit
• Annual Energy Production = (from the previous example, 100 kW system) ≈100×1400=1,40,000 units/year

Steps:

1. Calculate Annual Savings:
   Annual Savings = 1,40,000×10 = ₹14,00,000
2. Calculate Breakeven Point:
   Breakeven Point (years) = 60,00,000 / 14,00,000 ≈ 4.2 years

This means the housing society would recover the solar installation cost in about 4.2 years from saving on electricity bills.

Q4. What is the maximum subsidy a housing society can avail through PM Surya Ghar Muft Bijli Yojana?

Ans. Housing societies can receive a government subsidy of ₹18,000 per kilowatt, up to ₹90 lakh for a maximum of 500 kilowatts, under the National portal for rooftop solar subsidy.

Q5. Is solar maintenance necessary for housing societies?

Ans. Yes, solar maintenance is necessary to ensure optimal performance of the solar power systems. Over time, panels can accumulate dust, debris, bird droppings, and other residues that can significantly decrease their effectiveness. 

One of our housing society projects, Prestige South Ridge in Bangalore, has diligently maintained their 268 kW solar plant with our comprehensive maintenance services. The result? This solar system has consistently exceeded its committed generation targets month after month, delivering an impressive 10% solar savings to the residents.

Scheduled maintenance, including cleaning and inspections, can prevent these issues, prolong the solar system’s lifespan, and ensure that the system continues to provide substantial energy savings for society.

Many housing societies, like yours, often grapple with exorbitant power costs that increase maintenance bills, thus distressing residents. But here’s some exciting news: housing societies are taking a bold step by switching to solar energy, and the results are astounding!

With government subsidies like PM Surya Ghar Muft Bijli Yojana, adopting solar is becoming a lucrative and smart choice. Thus, housing societies can upgrade their energy requirements while contributing to a greener future.

If you are a committee or RWA member and you’re thinking about going solar, this article covers–

• A few essential factors to consider before your society goes solar 
• The approximate cost of solar for an RWA or Management Committee 
• The available financing options 
• How you can choose the best solar solution with the right solar vendor for your housing society

The Price of Solar For Housing Societies: Factors to Consider

1. Electricity Consumption

Evaluating the society’s electricity consumption determines the feasibility and size of the solar system required. Collect electricity bills from the past year to analyse energy demand peaks and how much could be offset by solar energy. 

For example, if your average electricity consumption for the year is 1,40,000 units, the solar system size you would require–

1 kW solar = ~1400 units

Solar system size = electricity consumption/units generated per kW
= 1,40,000/1,400 
= 100 kW

2. Open Roof Space

Your roof should have enough open space to accommodate the solar panels without any form of shadow falling on the panels. Ideally, the system will face south and be angled at 10° to maximise sunlight exposure. Ensure no obstructions like trees, neighbouring buildings, TV dishes, or more, cast shadows on the panels.

Typically, a 1kW solar takes approximately 80 sq. ft. of roof space. For a 100 kW solar system, you need about 8000 sq. ft.

3. Sanctioned Load

The sanctioned load is the maximum amount of electrical power that a housing society can use from the grid, as determined by the electricity board. Verify your sanctioned load and ensure that your solar panel installation’s size does not exceed this approved limit. 

If your intended solar panel installation exceeds the sanctioned load, consider requesting an increase from the electricity board.

The Price Range of a Solar System for Housing Societies

The cost of a solar system depends on the capacity required to meet your society’s energy needs. It also varies based on the type and brand of solar panels chosen. However, one thing remains consistent: the subsidy across India is set at ₹18,000 per kW (up to ₹90 Lac).

Let’s look at an example to understand the costs better:

Project Capacity (DC): 100 kW  
Number of Panels Required: 185*  
Cost per kW: ₹45,000 – ₹65,000  

^{*For a 100 kW system using Mono-PERC bifacial solar panels: (100 kW / 0.54 (the wattage capacity per module for MonoPERC half-cut bifacial panels))}

Project Cost (Without Subsidy):  

Calculating at an average of ₹60,000 per kW:  
100 kW * ₹60,000 = ₹60,00,000  

Subsidy:  
₹18,000 per kW * 100 kW = ₹18,00,000

Total Project Cost (After Subsidy):  
₹60,00,000 – ₹18,00,000 = ₹42,00,000

This is a rough estimate to help you understand what to expect when planning your society’s switch to solar. 

The final price may vary depending on the panel brand/type and other variables chosen, but the savings and environmental benefits are clear!

Financing Options for Housing Societies

Financing can often be a major concern for housing societies for multiple reasons. Fortunately, several flexible and affordable finance options are available to help make the switch to solar more accessible without straining the Society’s budgets. 

1. Through Corpus

If the society has a healthy reserve, it can dedicate a portion of the amount to the solar initiative, eliminating the necessity for outside loans. The decrease in electricity costs will help restore the fund over time. With strategic budgeting and careful resource allocation, society can still address maintenance and emergency needs without exhausting its reserve funds.

2. Through OD Facility from the Bank

The OD facility is a great option if the society has a good relationship with the bank and can offer an overdraft loan at a lower interest rate. Typically, banks require a strong credit history, financial documents, and a viable project proposal. The society will need to discuss terms such as the overdraft limit and interest rates with the bank.

3. OPEX Financing

This financing type is a way to access solar energy without a large upfront investment. Your choicest solar vendor will design, construct, engineer, procure, monitor, maintain and own the solar system on your roof. 

It also involves signing a Power Purchase Agreement (PPA) where you will pay a monthly electricity bill to the solar system vendor, which is often cheaper than the regular DISCOM rates per unit.

4. Through 0 Investment Plan with Shree Rudra Power Systems

When you choose to go solar with Shree Rudra Power Systems, our Zero Investment Plan makes the process simple and affordable.

Here’s how it works:

1. Zero Initial Investment: The down payment you pay is reimbursed through the government subsidy, so you start with no out-of-pocket costs.

2. Easy EMIs: Your monthly EMIs are designed to match your electricity bill savings, so you’re essentially paying nothing extra.

3. Flexible Payment Terms: We offer flexible EMI options from 6 to 60 months, allowing you to pick a plan that fits your budget.

With our plan, you’ll see savings from day one, making your solar investment practically cost-free. It’s the smart, hassle-free way to go solar!

Choosing the Right Solar for Your Housing Society

When choosing a solar provider for your housing society, evaluate these factors for a smooth installation process and long-term satisfaction. 

1. Gauge Their Expertise

• Visit the company’s previous installations

Visit the locations where the company has already set up solar systems, ideally those comparable in size to your housing society. How are the installations performing? What is their overall condition, and how do they fit into the existing setup? 

Talk with residents or management to gather direct insights about their experiences.

• Check Google ratings and customer reviews

Check out reviews on Google, social media, and various review sites to assess customers’ satisfaction. Ask the company for testimonials or case studies highlighting successful projects and feedback from those society members.

• Assess their experience in handling housing society projects

How many housing society projects has the company successfully finished? Assess the technical qualifications of their team—look for relevant certifications, training, and proficiency in managing intricate installations.

2. Seek a Solar Partner with the right After-Sales/Maintenance capabilities

Regular maintenance keeps your housing society’s solar system running smoothly and maximises its lifespan. Just like your cars and AC units need routine servicing to avoid costly repairs, your solar system requires the same level of attention. 

Without proper upkeep, you risk facing unexpected breakdowns, reduced efficiency, and significant drops in energy production—issues that can disrupt the entire society and lead to higher expenses.

To protect your investment, choose a vendor that provides prompt support to quickly address any problems, minimise downtime, and ensure continuous energy generation. 

Look for:

• Comprehensive coverage: The maintenance service must include regular inspections, cleaning, repairs, and monitoring of system performance
• Response time: Confirm that the service agreement outlines the expected response times for resolving problems.
• Warranty and guarantees: Review the warranty conditions related to the solar panels and the quality of installation work.

3. Ensure Their Structures are Cyclone-proof

Are the mounting systems engineered to endure severe weather events like strong winds, intense rainfall, and storms? Are the components corrosion-resistant and durable to ensure longevity? Verify that the structures comply with applicable national and international safety and durability standards.

Here’s an example of a solar installation not built to withstand severe weather.

4. Check the Solar Partner’s Financial Strength and Payment Terms

Check the company’s financial health to ensure it can complete the project and provide ongoing support. Seek stability indicators, like a solid track record in the industry and positive feedback from suppliers and clients. 

Make sure to outline the payment terms clearly – initial payments, milestones, and final settlement. Check if the company offers flexible payment options, such as financing plans or phased payments based on project completion.

5. Ask for a Detailed Quotation

Key elements that should be included in a quotation from the ideal solar vendor include–

• System design: Comprehensive design details, specifying the quantity and kind of panels, inverters, and other necessary elements.  
• Cost breakdown: A clear breakdown of solar panel installation costs, including equipment, installation, maintenance, and additional fees.
• Timeline: A timeline outlining the entire project duration from installation to commissioning.
• Warranties and guarantees: Details of warranties for the panels, inverters, and installation workmanship.

Get multiple quotations and compare them based on the cost of solar panel installation, quality, services offered, and terms. Consider the overall value rather than just the lowest price. The cheapest option may not always provide the best long-term value.

   Annual Savings = 1,40,000×10 = ₹14,00,000
2. Calculate Breakeven Point:
   Breakeven Point (years) = 60,00,000 / 14,00,000 ≈ 4.2 years

This means the housing society would recover the solar installation cost in about 4.2 years from saving on electricity bills.

Q4. What is the maximum subsidy a housing society can avail itself of through PM Surya Ghar Muft Bijli Yojana?

Ans. Housing societies can receive a government subsidy of ₹18,000 per kilowatt, up to ₹90 lakh for a maximum of 500 kilowatts.

Q5. Is solar maintenance necessary for housing societies?

Ans. Yes, solar maintenance is necessary to ensure optimal performance of the solar power systems. Over time, panels can accumulate dust, debris, bird droppings and other residues that can significantly decrease their effectiveness. 

Scheduled maintenance with cleaning and inspections can prevent these issues, prolong the solar system’s lifespan, and ensure that the system continues to provide substantial energy savings for society.
