• Earlier, polycrystalline solar panels were a more popular choice for residential installation since they were more affordable. But now, new technology solar panels – bifacial and mono PERC – are widely used.
• Many new higher-performing materials have been discovered – perovskite, heterojunction and tandem solar cells.

You must know all the specifics about the latest technology in solar panels because the system you install today will last for at least 25 years. 

Here’s a compilation of two new technology solar panels that homeowners should be aware of.   

Latest Technology in Solar Energy: The Most Practical Panel Types for Residential Installation 

1. Bifacial Solar Panels

Traditional solar panels collect direct sunlight from one side only. However, bifacial solar panels have solar cells on both sides. 

The upper layer absorbs direct sunlight. The bottom layer absorbs the sunlight that the top layer reflects. Bifacial solar panels generate more electricity than their predecessors since they can capture and convert more sunlight.  

Here’s why this matters: 

• Increased energy yield: Bifacial panels have shown up to 30% more energy production than traditional solar panels in labs. The current practical output is up to 22%. With more research underway, the efficiency of bifacial panels will only increase. 
• Versatile installation: Bifacial solar panels are ideal for you if your rooftop has a high-reflective surface or you live in areas where it snows a lot.
• Longevity: Bifacial panels often come with more durable construction and extended warranties. Their degradation rate is just 0.45% to 0.55% per year. 

2. PERC (Passivated Emitter and Rear Cell) Solar Cells

PERC technology adds a passivated layer of solar cells on the rear side, a massive upgrade from traditional panels. Including an added layer improves the efficiency of the solar panel, as it can capture sunlight from the rear side as well. The latest innovation in PERC technology is the MonoPERC solar panels. 

This innovation matters because of the following reasons. 

• Boosted efficiency: By capturing light that would otherwise be wasted, PERC cells significantly increase the energy output of solar panels. In Mono PERC panels, this efficiency shoots up to 25%.
• Better performance in low-light conditions: These cells perform exceptionally well in low-light conditions, making them versatile across various climates.
• Reduced costs over time: The initial investment might be slightly higher than old technology panels, but the increased efficiency means quicker payback times and long-term savings.

Future Technology to Keep an Eye on

Technology constantly evolves. Here’s a snapshot of the future and whether it’s worthwhile to hold up your installation until the trends fully explode! 

1. Perovskite Solar Cells

Perovskite cells, which break records with efficiencies over 30% in the lab, are considered the solar industry’s future. They offer the flexibility to be used on surfaces where silicon can’t be used.  

However, perovskite is still in its early development stages. While it might be ready for large-scale installations within a decade, the mass adoption of perovskite solar cells for the residential sector is still a pipeline dream, primarily because of their high cost. 

2. Transparent Solar Panels

Transparent solar technology integrates into windows and glass surfaces, turning buildings into power generators without blocking the view. Although thin-film panels are great options for commercial installations, they are not viable for mass residential solar installations in India.

They might see a future in commercial offices because of the following reasons. 

• Architectural freedom: They blend seamlessly with modern design, offering energy solutions without aesthetic compromises
• Increased surface area: Every glass surface becomes a chance to generate power, vastly expanding solar energy’s reach

3. Heterojunction Solar Cells

Heterojunction technology (HJT) combines the best of two worlds — crystalline silicon and amorphous silicon layers — to create solar cells with enhanced efficiency.

HJT cells achieve higher efficiency rates by enhancing the absorption of sunlight and reducing electron recombination, pushing the boundaries of solar power productivity. 

In fact, these cells also perform exceptionally well under high temperatures since they have a higher temperature coefficient.

4. Tandem Solar Cells

Tandem solar cells layer two different types of photovoltaic materials — such as silicon and perovskites — to capture a broader spectrum of sunlight and thereby convert more light into electricity. 

By harnessing light across different wavelengths more effectively, tandem cells break through the theoretical efficiency limits of single-material solar cells.

As research progresses, tandem technology is expected to become more affordable and scalable, making ultra-high-efficiency solar panels the standard.

5. Thin Film Solar Cells

Characterized by their lightweight, flexible design, Thin Film solar cells can be applied to various surfaces, making solar installation more versatile than ever.

Their flexibility opens up new applications for solar power, from portable electronics to unconventional building integrations. Generally cheaper to manufacture than silicon-based cells, they offer a cost-effective solution for large-scale installations.

6. Floating Solar Farms

Solar takes to the water with floating solar farms. Installed on lakes and reservoirs, they’re a smart solution to land use challenges.

Here’s why this technology has become the talk of the town:

• Cooling effect: Water beneath the panels keeps them cool, boosting efficiency. This naturally reduces the chances of panels being affected when the mercury soars
• Water conservation: They reduce evaporation from water bodies, conserving precious resources

7. AI-Optimized Energy Systems

Integrating Artificial Intelligence with solar systems will make solar power systems more intelligent and efficient. Here’s how:

• AI algorithms can forecast energy production and demand, ensuring optimal energy distribution
• Real-time monitoring will help in predicting maintenance needs, reducing downtime and costs
• AI will enhance the ability of solar systems to integrate smoothly with the grid, balancing supply and demand effectively.

However – should you wait for these technologies to fully emerge before you install solar at home? The answer is no. 

These technologies are still in their very initial phases. Their evolution and manifestation could take a decade. Considering how swiftly electricity tariffs are increasing, there’s no better time than now to install solar panels and benefit from them.  

Top 4 Benefits of Adopting New Technology for Solar Energy 

1. Advanced materials and designs, such as PERC and bifacial panels, push the efficiency envelope. Higher efficiency translates to more electricity, which significantly cuts down the electricity bills 
2. The initial investment in solar technology is offset quicker, thanks to the new technology of solar panels that have a higher efficiency rate
3. By harnessing renewable energy from the sun, solar systems decrease carbon emissions, directly combating climate change
4. The solar industry’s growth spurs economic development, driving demand for jobs in manufacturing, installation, maintenance, and research and development

But do you know a considerable amount of power is lost in this transferring process?

Yes, you hear us right. 

What’s more notable is that these losses lead to the heating up of the transformer, which affects its efficiency. Therefore, it becomes important to calculate transformer losses to keep its efficiency under check.

Now you must be thinking, what are transformer losses, and why do they occur?

Don’t worry, we have got you covered!

In this blog, you will learn all the important aspects that relate to how you can calculate transformer losses. 

So, let’s dive in!

What is the Function of a Transformer?

Before we start with transformer losses, let’s understand how a transformer works.

You may have seen compact structures around your house in the electric power grid. These structures constantly convert high voltage power into low voltage to meet the requirements of different residential or commercial spaces.

It is important because most power grids supply 220 kV or 440 kV across different power stations. Such a high-power electric current can cause potential harm to various electronic devices. Therefore, transformers are used to step down the electric voltage for safe power consumption.

What are Transformer Losses?

To calculate transformer losses, it is vital to understand what these losses are.

As mentioned above, a transformer has no moving parts. There is no mechanical loss during the power distribution process. As a result, it has extremely high efficiency, above 90%. 

Then what is transformer loss?

The answer lies in the loss caused by load difference that occurs due to differences in the input and output voltage, which increases the temperature within the transformer structure.

When you calculate transformer losses, you will learn that these losses are categorised as core losses and copper losses. These losses are similar to other DC devices, except for zero mechanical loss.

4 Types of Transformer Losses

Now that you know the meaning of transformer losses, let’s explore another factor that is crucial to calculate transformer losses. Broadly, there are four types of transformer losses. These are explained below:

#1. Resistive Loss

In simple terms, this loss is known as copper loss, which is the result of the resistance of copper wire that is used for winding. This loss occurs because higher load frequency makes the electron move towards the outer surface of the conducting wire. The electrical fluctuations reduce the size of copper wire and increase resistive loss.

#2. Eddy Current Loss

Power loss in a transformer that is caused by currents created in the metal components is known as eddy current loss. Any conductor that is exposed to a moving magnetic field experiences induced voltage and current.  

#3. Hysteresis Loss

This loss occurs in a transformer due to remaining magnetism in the structure even when the magnetising force is removed. Magnetic parts are small sections of materials that act together when a magnetic force is applied. Due to this force, all the magnetic parts are realigned. The realignment process consumes power, which is used to calculate transformer losses. 

In simple terms, the movement of magnetic particles creates heat in the transformer, leading to hysteresis loss. 

#4. Flux Loss

When some of the flux lines from the primary can not pass through the core and to the secondary, a transformer gets flux loss, which results in a loss of electric current. 

There are two basic explanations for why flux lines move via the atmosphere rather than the core. These are:

• The iron core gets saturated, which prevents it from accepting any more flux lines. As a result, the lines of flux go through the air without being interrupted.
• Second, in the unsaturated area, the air and core normally have a reluctance ratio of 10,000:1. Accordingly, there is 1 line of flux via the air for every 10,000 lines of flux through the core. 

What is Transformer Efficiency?

Transformer efficiency is known as the ratio of its output to the input. To know the effects of voltage fluctuation when you calculate transformer losses, its efficiency is considered.

Generally, the efficiency is expressed in percentage. Moreover, the following formula is broadly applied for calculating the transformer’s efficiency:

= PoutPin

Here,

• represents the efficiency of the transformer.
• Pout is the transformer’s output power in watts.
• The Pin is the transformer’s input power in watts.

Can you Determine the Efficiency of a Transformer?

Now the question arises if it is possible to know the exact efficiency value once you calculate transformer losses.

To get the answer to this question, let’s consider the following situation.

A conventional transformer’s efficiency ranges from 96% to 99% and is generally very high. So, it is quite challenging to accurately measure the output and input of a transformer to assess its efficiency.

The main variance between output and input and output readings of machines is so negligible that a 15% range of instrument error will result in an error within the transformer wastes.

Conclusion 

The transformer helps in the even distribution of power from the electric grid. Due to their static structure, there is hardly any damage to their mechanics. However, the fluctuation and difference in output and input voltage results in some loss. Therefore, to get its maximum benefit, it is important to calculate transformer losses. 

FAQs

1. How many types of transformer losses are there?

Transformer losses are broadly categorised into the following four types:

• Flux loss
• Hysteresis loss
• Eddy current loss
• Resistive loss

2. What is the efficiency range of conventional transformers?

Generally, the efficiency of a conventional transformer ranges between 96% to 99%.

3. What is the most common reason for transformer loss?

The difference between input and output voltage creates heat in the transformer structure. This is the primary reason for transformer loss.

To make an informed decision to install a solar system for factory, you should pay careful attention to the information provided in this article. Dive in and explore the benefits of installing a solar power system for factory like never before. 

Advantages of a solar powered factory

1. Saving energy

Electricity expenditure is a source of major concern for every commercial establishment. 

Power costs depend on the factory’s size and usage of grid electricity. However, by installing a solar system for factory, you not only bring down your energy costs but become an energy producer as well. 

Solar modules reduce electricity bills substantially. By exporting surplus energy generated by your solar plant factory, you bring a great benefit to the grid through net metering facilitation. This is particularly beneficial to industrial premises and factories where electricity usage may not be continuous or uniform. 

2. Reduction of carbon footprint

The normal electricity used by us all, factories included, is generated from non-renewable resources such as fossil fuels and coal. This has an enormous impact on the carbon footprint and contributes vastly to all kinds of pollution and global warming. 

Thus, a solar system for factory would not only help with reducing electricity bills but also gives you a chance to positively contribute to the environment. Your solar powered factory ensures a smart alternative to carbon emissions; thus, encouraging the usage and production of cleaner and greener energy.

Did you know that the iceberg A-76A that’s one piece of what used to be the largest glacier in Antarctica is on the verge of melting as well? 

Global warming due to carbon emissions is a serious demon that the world needs to fight without a delay. And installing a solar power system for factory is a great step towards the cause. 

3. Tax benefits

By moving towards a solar system for factory, you open your business up for the various tax benefits the government provides. It is a significant yet unfamiliar advantage of using solar systems for commercial purposes.

For instance, in normal circumstances, you receive only a 5% depreciation against the cost of your asset. However, by installing a solar system for factory on the roof of your commercial establishment, you increase this accelerated depreciation to 40% against the cost of your asset.

The Indian government actively promotes solar systems for factory and other industrial infrastructure through tax reliefs. Needless to say, your business could save a tonne of money through these tax cuts.

4. Energy independence

By the installation of a solar system for factory, your business establishment becomes energy-independent. It means, your dependency on the grid reduces sharply. 

Instead, your factory will be its own energy supplier. In fact, the tables can be turned, and you may be able to supply the power company with surplus energy. You are now an electricity generator as opposed to your earlier position of being an electricity consumer.

Through this one-time investment, your factory can shrug off all dependency on power companies that can sometimes be unreliable and erratic in their services. 

Moreover, power interruptions due to natural and other causes are all too common and can wreak havoc in a large business establishment such as a factory.

The cost of installing a solar system for factory can be more than compensated by the enormous reduction in overhead costs by way of eliminating commercial power dependency. 

The salient fact here is that a solar power plant for factory guarantees an uninterrupted power supply characterised by low maintenance and zero carbon emission.

Conclusion

This article has touched on the most common benefits of utilising a solar system for factory. You can further exploit these benefits by making the right choice of a solar system for factory. 

It can be done by choosing a system based on your particular requirements that would yield maximum efficiency and power generation to your solar powered factory. 

Additionally, a solar system can ensure that your business flourishes due to a significantly greater return on investment.

In conclusion, we urge you to channel the generous power of the sun to enjoy consistent electricity generation, uninterrupted work operations, tax cuts, selling of your surplus power, and the satisfaction of making Mother Earth cleaner and greener.

FAQs

1. Does the Indian government provide tax relief for installing solar systems on your business infrastructure?

Yes, the Indian government provides tax cuts to solar-powered assets.

2. What percentage of depreciation do you get for installing solar system for factory?

You would receive a 40% accelerated depreciation against the cost of installing a solar system, as opposed to the 5% depreciation under normal circumstances.

3. How long does a solar power plant last? 

Generally, solar panels can withstand snow, hail, and wind and are extremely durable. The different components of a solar power system for factories could require some replacement after a certain period of time. 

Still, solar panels are entirely sufficient in providing electricity for approximately 25.  Even after 25 years, their working efficiency remains at about 70%. 

4. Why is solar energy important for industries?

Industrial establishments such as factories are great consumers of electricity. When this energy is of the conventional, non-renewable kind, the factories are also huge carbon emitters. 

Thus, switching to highly sustainable greener energy choices such as solar systems can create an enormous positive impact on the environment. 

Furthermore, solar systems allow industries to have higher returns on investments.

An assessment of the sizing of solar panels can also assist with a better installation, which in turn improves performance and efficiency. Sizing the solar panels can sometimes be tricky. We have outlined below a thorough 7-step process that can guide you through the business of identifying the right size of panel that meets your every requirement.

6-Step Guide to the sizing of solar panels

1. Selecting the PV module

When selecting a PV module, some factors to be considered are technology, cost, availability, warranty, efficiency, and service support. 

The technology is of two types: mono or poly panels. Poly panels are generally more affordable than mono panels. People, thus, often choose poly panels, especially when space availability is not an issue. 

On the other hand, with an efficiency of 19-20% mono panels perform better than poly panels which have an efficiency of 16-17%. If there’s a shortage of shadow-free space on your rooftop, then mono panels are the way to go. 

The selection of PV modules also depends on availability. Did you know that even if the panel is assembled in India, the PV cells required to make that panel come from China? Hence, keep the availability factor in mind when choosing a solar panel for your home. 

2. Calculating the number of modules

The number of modules can be easily calculated in the following manner:

Say you have a module of 350 Wp and you want to set up a 10 KW solar system, here’s what you need to do: Divide the capacity of the solar system (in watts) by the capacity of the module. 

In this case, the total number of modules = 10,000 / 350 = 28 

The requirement is, thus, 28 modules in the sizing of solar panels in this case. 

3. Selecting an inverter

The inverter selection follows the same process involved in selecting the module. As with the module, you can choose an inverter based on cost, efficiency, availability, technology, service support, and warranty. For inverters, there are two technologies available – string and micro. 

String inverters have a direct connection to the grid and are commonly used for commercial and residential purposes. Microinverters, on the other hand, are smaller and costlier than string inverters. But their cost is justified in terms of efficiency.

You can select the inverter that best suits your home’s needs.

Calculation of the number of inverters 

Assuming that the selected inverter is 2500 Wp and the total required wattage is 10,000 watts (10 kW), then, the total number of inverters required would be 10,000 / 2,500 = 4

Hence, in this case, For the sizing of solar panels for your residence, you would need four inverters.  

4. Calculating the string size

The string size of inverters can be calculated using software; however, there is some information that you will need beforehand. This information includes the Voc of the PV module, Mppt range of the inverter, Vmp of the PV module, and Vmax range of the inverter. 

Once you gather this info, it is simply a matter of using the appropriate software to determine the string size you will need for the sizing of solar panels for your house.

5. Selecting the mounting structure

The mounting structure has to be selected based on some factors, such as the type of roof structure, snow/wind load, type or tilt of mounting, type of environment, structure material, and cost. 

• Mounting structures are of different kinds and classes, such as fixed tilt, flush mount, ballasted solar structure, single-axis tracking, and east-west racking. 
• Also, when choosing the mounting structure, it is necessary to focus on the tilt. Generally, the ideal installation method is such that the panels should stay near-perpendicular to the sun between peak sunshine (between 11 AM to 2 PM). 

6. Simulation

The last step of assessing the appropriate sizing of solar panels is simulation. Simulation software assists engineers in improving the design of your solar system, particularly concerning shadow analysis.

Conclusion

The aforementioned 6 steps offer a clear idea about the calculations required to assess the sizing of solar panels for your home. The calculations will, of course, vary on a case-to-case basis. However, the main aim remains the same: sizing of solar panels in such a way that all your power requirements can be met with electricity from solar.

FAQs 

Q. How do PV panels work? 

Now that you know all about the sizing of solar panels, it’s also relevant that you understand their basic functioning. 

It’s simple.

Solar panels absorb sunlight between 9 AM to 4 PM and convert it into direct current (DC). This DC electricity passes through an inverter to be converted into usable AC electricity. Surplus energy is transferred to the grid in the case of an on-grid solar system. 

Q. How do you select a PV module?

PV modules are of two types- poly and mono, of which the former is more affordable, bulkier, and less efficient but readily available than the latter. Thus, you will have to decide which PV module fits your particular needs.

Q. What are mono and poly solar panels? 

Mono or poly panels are both PV panels that are used to convert sunlight into electricity. However, how they are manufactured is different. 

Monocrystalline solar panels are made with one single crystal of silicon; hence, their efficiency is on the higher side (19-20%).

On the other hand, polycrystalline solar panels, also knoware made up of multiple crystals of silicon. Which is why they’re also known as multi-crystalline panels. Their efficiency is about 16-17%, that’s lower than that of mono panels.  

Q. How are modules distributed amongst the inverters in a solar system during the sizing of solar panels?

This can be done through a simple calculation. Divide the number of modules by the number of inverters in your system. Voila! You have the number of modules required per inverter during the sizing of solar panels. 

This calculation is just a guide. During the actual installation process, you may have to vary the numbers for practical reasons.

Q. What is the maintenance cost of solar panels? 

Solar panels are not high-maintenance products. The AMC contract will always cover basic maintenance requirements as long as you’ve purchased a tier-1 module from the right brand. The premium-quality modules have a life of a minimum of 25 years.

What are the components of a solar conversion kit?

The solar conversion kit has two parts: a PV panel and a solar converter. The PV panel, or photovoltaic panel or solar panel, is put on the rooftop to capture the sun’s energy. ‘Photo’ represents photons or light energy, and ‘voltaic’ refers to voltage. So solar cells or PV panels convert sunlight into electricity.

A Solar converter or Solar Charge Controller is the main component that converts your regular inverter to a solar inverter. It connects with solar panels as well as with batteries. It is responsible for regulating voltage and charging and discharging the battery. 

Advantages of Solar conversion kit

• Environmentally friendly: Instead of depending upon fossil-fuel-generated energy, the kit utilises the sun’s light. The use of renewable energy over non-renewable sources makes it eco-friendly.

• Reduction in electricity consumption from the grid: The kit converts solar light into electricity. Hence, it does not require power from the grid, which reduces electricity bills. 

• Acts as both types of inverter (regular and solar): It draws voltage from solar energy and stores it. The stored energy is used as and when required; thereby, the converter plays the role of a regular inverter too.

• Utilises a standard inverter: The standard inverter does not need to be replaced. The solar converter has a provision to connect with the inverter. Thus, utilising the money spent on the inverter.

• No reverse flow of current to solar panel: The solar charger will not send the current from the battery to the solar panel. Thus, saving the stored power.

Variety of solar conversion kit

Based on the type of technology used, the categories of solar conversion kits are as follows:

1. Maximum Power Point Tracking Technology Solar Charge Controller

MPPT kit holds an efficiency rate of 96% by utilising the solar panel’s maximum power. However, they cost more. The most reputable brand names manufacturing MPPT solar charge controllers are Smarten and UTL.

2. Pulse Width Modulation Solar Charge Controller
