What is Solar Panel?

Solar Panel is a device that converts sunlight into electricity.

What is a Solar Panel made up of ?

Solar panels are made up of crystalline silicon cells that generate electricity in the presence of sunlight.

How do Solar Panel work ?

Solar panels absorb sunlight that falls on the photovoltaic cells. The chemical composition of the cells generates direct current (DC). This is converted to usable alternating current (AC) with the help of inverter technology.

How many Solar Panels are needed to run a house ?

It depends on the size of the house and electricity consumption rate and the usage pattern of the residents.
Generally, 1kW system requires 3 panels (assuming Poly DCR 72 cells) which generates approximately 120 units per month. You can check your electricity bill and calculate your requirement or use our solar calculator.

How long do Solar Panels last ?

Solar panels last for about 25 to 30 years. However, this doesn't mean that they stop producing electricity after 25 years – it just means that energy production is reduced by 80% of the panel’s actual capacity; and might not be sufficient to meet the energy requirement of the place.

How much will I really save on my electricity bills with Solar Panels ?

You can save up to 70–90% of your monthly electricity bill. And your bills come down to zero from the first month itself. It majorly depends on the electricity consumption rate of your home or business. Solar energy gives an alternate option to reduce electricity bills. In 2021, the average residential tariff in India is Rs.7.50/unit whereas if we use solar electricity, the cost comes down to Rs.2.50/unit, which is lowered by 1/3.in India, the average residential tariff is Rs.7/unit whereas if we use solar electricity, the cost comes down to Rs.2.50/unit, which is lowered by 1/3.

What is the cost of a Solar Panel ?

The price or cost of a solar panel depends on the power-rating and the type of solar panel. Generally, a solar panel in India costs between Rs.22-26 INR per watt.

What are the types of Solar Panels ?

    There are mainly three types of Solar Panels used for commercial purposes.

  • Mono-crystalline Solar Panel
  • Polycrystalline or Multi crystalline Solar Panel
  • Bi-facial Solar Panel.

Other panels like thin-film and flexible solar panels also exist. But they yield very less electricity and are meant for specific applications only.

What is a Mono-Crystalline Solar Panel ?

Monocrystalline solar panels have solar cells that are made from a single crystal of silicon, which is formed into bars and cut into wafers. As we know the cell is composed of a single crystal, so electrons that generate a flow of electricity have more room to move. This makes monocrystalline panels more efficient than all the other solar panels.

What is a Polycrystalline Solar Panel ?

Polycrystalline solar panels, just like mono, are also made from silicon. However, instead of using a single crystal of silicon, entire silicon with several fragments is melted together to make the solar wafers or solar cells.
Polycrystalline solar panels are also known as ‘multi-crystalline panels’. There are many crystals in each cell, which enable less freedom for the electrons to move. As a result, Polycrystalline solar panels are relatively less efficient than Monocrystalline panels.

What is Thin-film Solar Panel ?

Thin-film Solar Panels are a totally different technology as compared to Mono-crystalline solar panels and Poly-crystalline Solar Panels. A thin-film Solar Panel can be identified as a solid black, frameless panel. These are least efficient of all the crystalline Solar Panels.

Which is the best Solar Panel ?

Mono-crystalline Solar Panels have the highest efficiency of 20-22 %, when compared to other types of solar panels, that is, it converts more than 20 to 22% of sunlight into electricity.

How do I identify a Mono-Crystalline Solar Panel ?

A Mono-Crystalline Solar Panel can be identified from the solar cells which appear as a single flat color (usually black) and are made from a single crystal of silicon.

What is the cost of a Mono-Crystalline Solar Panel ?

Mono-Crystalline Solar Panels are the most efficient of all the solar panels. Mono-crystalline solar panels in India, cost between Rs.24 - 26 rupees (INR) per watt.

What is the cost of a Polycrystalline Solar Panel ?

Do solar panels work in the rain?

Solar panels use direct sunlight to generate electricity. Unless, there is reflected or even partial light from the clouds, solar panels will still work. However, the efficiency of electricity generation capacity goes down.

Do Solar Panels work at night ?

No! Solar panels do not work at night. They require sunlight to generate electricity. But the energy stored during peak sunlight hours can be used during nighttime.

Which Solar Panel is better: Mono-Crystalline or Polycrystalline ?

Mono-Crystalline Solar Panels have the highest efficiency amongst all the panels. Mono-Crystalline Solar Panels convert more than 22% of sunlight into electricity. They are space-efficient and occupy less amount of space. However, they are more expensive than Polycrystalline Solar Panels. On other hand, Polycrystalline Solar Panels give marginal efficiency in effective price and productivity. Thus, they are preferred commercially.

What are the advantages of Solar Energy ?

Some advantages of using solar energy are as listed below.

  • Solar power is pollution free and causes no greenhouse gases emissions post installation.
  • It leads to reduced dependence on foreign oil and fossil fuels.
  • We get renewable, clean power that is available on each day of the year; even on dark cloudy days.
  • Yields return on investment unlike paying for utility bills.
  • Virtually, no investment-check or maintenance is needed as solar panels last over 30 years.
  • Excess power can be sold back to the power company on the inter-tied grid.
  • One can live without being grid dependent, if all the power generated is enough for the home / building.
  • Solar Systems can be installed almost anywhere; in a field or on top of a building.
  • The Solar power can be stored in batteries for use at night.
  • Solar Energy can be used to heat water, power homes and buildings, and even power cars.
  • Efficiency is always improving so the same size solar that is available today will become more efficient tomorrow.
  • Aesthetics are improving making solar energy more versatile as compared to older models; i.e. printing, solar shingles, etc.

How long will a Solar System installation take ?

A typical residential solar system installation takes about 40 hours of installation time on the roof and about 10 hours inside the house. The PIXON team typically sends two technicians, so most of the job is completed in 2-3 days. Read more about it here. All the commercial, industrial or institutional installations take time based on the size of the solar system being installed.

Who actually installs the Solar Panels ?

PIXON takes pride in being the manufacturer as well as the installer of solar modules. This means you have a consistent trusted experience with one company, all ensured to provide you with the best product as well as system warranty, maintenance, and servicing. Our installation crew is skilled and certified.

Why should I go solar now? Aren't innovative new technologies on the way ?

Putting it simply – the sooner you get solar, the sooner you will enjoy its benefits! If you wait for some unproven technology down the road, you will have missed the opportunity to generate your own power now. Solar is like saving for retirement – the sooner you start doing it, the better.

Which direction should the solar panels face and why?

Solar panels need to face true south direction for maximum power generation. The reason behind it is that when the sun transits from east to west, it leans towards the south direction. Irrespective of which part of the year it is, the inclination will always be towards the south. Hence for the optimum harnessing of sunlight, the solar PV panels should ideally face south.
For example, a 7*12 roof that is due east or due west still achieves 77% of a system’s potential performance. More important than angle, generally, is shading. The solar panels should not experience shading from 9 am to 3 pm, year-round. Technological improvements such as micro-inverters can compensate for shading issues to some extent.

How much roof space will I need for a Solar Panel ?

Every kW (kilowatt) of the solar array takes about 100 square feet. So a typical 3kW array (twelve panels) will take a roof area of about 11*20 inches (two rows of six).

How will I know if the solar panel is working?

Today, almost all inverters come with built-in monitoring, which varies a little based on manufacturers. Also, by reconciling your production with your electric bill, you can get a good idea of what your household’s electric load is and how much of a difference the photovoltaic system is making to your bills.

Can solar panels increase the value of my home?

Yes! Several studies demonstrate that solar homes add to property valuation and sell more quickly.

Will my property taxes go up because of solar?

The true answer is – it depends. Most municipalities will not increase your property tax values due to a solar installation, but it’s worth checking with your town (or city) legislatures to be sure.

Will I see a difference in my lights or in how appliances run with solar, like on a generator?

Solar electricity is identical to grid power. So, you will never notice that the house is running on solar power. What you will see, of course, is a lesser or almost zero electricity bill to pay!

How many years do solar panels generate power?

Solar panels sold today don’t ever stop generating. While some of the wirings may need upgrading in future years, the panels remain useful for over 40 years. However, the generation capacity does reduce from the original over the years after the warranty-period.

What is net metering?

The solar panels produce a lot of energy during the day when the sunlight availability is at its peak. The house most likely won’t use all this solar-generated power. The excess solar power is fed back to the grid. At night, the extra units are taken back home from the grid. It works like a banking system.
An electric meter on your property is used to record how much energy your home or business uses every month. When you switch to solar energy, you’ll have a new electric meter replacing the old one. It works both ways, that is, it shows how many electricity units you consume from the grid when your solar panels aren’t generating electricity (like at night). It also shows how much energy your solar panels generated during the day. While you pay only for the extra units you consume than what your solar system generates. This is known as net metering.

Are solar panels difficult to maintain?

Solar panels are easier to maintain than your property, appliances, and maybe even your cell phone. That’s because solar panels have zero moving parts. The most you’ll have to do to maintain your solar panels is to make sure they’re free of dust, pollen, leaves, animal drooping and other debris. Anything that obstructs your panels will make them less efficient in energy production. You can read here in detail about how to clean your solar panels.

How does solar energy benefit the environment?

Solar power is a renewable resource, which means it is freely available. We would never have to dig for coal or refine other toxic energy sources just to keep the lights on. Solar energy reduces your carbon footprint by decreasing greenhouse gas emissions (which contribute to climate change). Since it doesn’t cause any pollution, it also means we’ll have less harmful pollutants in our air, land, and water.

Is solar energy used in Diverse Applications?

Yes. Solar energy is used for diverse applications and purposes. You can generate electricity (photovoltaic) or heat (solar thermal) from solar energy. Solar energy in the form of heat can be used in: solar water-heaters, cookers, calculators, etc. Solar energy (in the form of photovoltaic) can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited clean water supplies and to power satellites in space. Solar energy can also be integrated into the materials used for buildings.

Are there different types of technologies associated with solar power?

There are a variety of types of technologies associated with solar power. These technologies can be divided into two groups.

  • Solar Thermal Technologies – Use the sun’s heat. Example: solar concentrator power systems, flat plate solar collectors, and passive solar heating.
  • Solar Photovoltaics – Use the sun’s light or radiation. The photons of radiation are used to generate electricity through the photoelectric effect by using photovoltaic (also known as PV, that is, solar panels and or solar modules).

Is EVA Rubber or Plastic ?

EVA is a copolymer of Ethylene Vinyl Acetate. It is rubber or plastic based on its VA content in it.
If the VA content is in the range of 4-5 %, the EVA composite has polythene properties and characteristics.
The VA content ranging between 5-30% gives it the properties of thermoplastic.
If the VA content is near to 40% or anything greater than it acquires EVA rubber properties.

Is EVA Waterproof ?

Yes. EVA is a waterproof material.

Is EVA Plastic Biodegradable ?

Yes. EVA plastic is a biodegradable material.
The biodegradable Ethylene Vinyl Acetate (EVA) plastic is the copolymer of ethylene and vinyl acetate polymers.

Is EVA Material Strong ?

What is the duration of warranty on Solar Panels ?

Solar PV panels manufactured as per global standards are robust and can withstand the harsh weather conditions of nature. Generally, solar panels come with a product warranty of 10 years and a performance warranty of 25 years. With evolving tech, the performance warranty has increased to 30 years. So, you should not worry about the solar panels working and warranty period as they need the least maintenance and care.

Where can Solar Plants be installed ?

Solar panels can be installed almost anywhere, on the ground or rooftops. The rooftop systems can be installed at the roofs of residential, commercial complexes, housing societies, community centers, government organizations, private institutions, Industrial, etc.

In case of grid failure, is there any chance for electric shock to the person who is repairing it? What is “Island Protection” ?

In case the grid fails, the solar power must be fully utilized or disconnected from the grid immediately. This is done to stop current feeding on the grid, so as to safeguard any grid person/technician from getting electrocuted while working on the grid for maintenance and fixing. This feature is called "Island Protection".

How much roof area is required to set up the grid-connected rooftop solar system?

1 kW on-grid or grid-connected rooftop solar system generally requires 10 - 12 sq. meters (100 square feet) of flat and shadow-free area (preferably south-facing). Actual sizing, however, depends also on local factors of solar radiation, weather conditions, the shape of the roof, and type of solar panels used in the system.

Are all consumers eligible to install solar rooftop systems to avail net metering facilities?

Yes. All registered metered consumers coming under the jurisdiction of their respective State Electricity Board are eligible for installation of the solar system, based on their respective state policies.

What is net metering?

The solar panels produce a lot of energy during the day when the sunlight availability is at its peak. The house most likely won’t use all this solar-generated power. The excess solar power is fed back to the grid. At night, the extra units are taken back home from the grid. It works like a banking system.
An electric meter on your property is used to record how much energy your home or business uses every month. When you switch to solar energy, you’ll have a new electric meter replacing the old one. It works both ways, that is, it shows how many electricity units you consume from the grid when your solar panels aren’t generating electricity (like at night). It also shows how much energy your solar panels generated during the day. While you pay only for the extra units you consume than what your solar system generates. This is known as net metering.

Among "net metering" and "gross metering", what is preferred?

The net metering mechanism is more popular in India.

How critical is the quality of the structure on which the solar panels are mounted?

It is the most critical part as it acts as the skeleton for the entire system. A sturdy structure is mandatory as it needs to withstand strong winds and other natural forces. The structures are mostly made of galvanized iron, which is not only stronger than normal iron but also rustproof as well, making the solar power system last longer.
The structure for rooftop solar installation on a flat roof is completely different than that for a slanted roof. The height of your roof is another major factor that determines the composition and alignment of the structure. The quality of the material used has to be as per the MNRE (Ministry of New and Renewable Energy-India) specified norms.

Which direction should the solar panels face and why?

Solar panels need to face true south direction for maximum power generation. The reason behind it is that when the sun transits from east to west, it leans towards the south direction. Irrespective of which part of the year it is, the inclination will always be towards the south. Hence for the optimum harnessing of sunlight, the solar PV panels should ideally face south.
For example, a 7*12 roof that is due east or due west still achieves 77% of a system’s potential performance. More important than angle, generally, is shading. The solar panels should not experience shading from 9 am to 3 pm, year-round. Technological improvements such as micro-inverters can compensate for shading issues to some extent.

At what angle, one needs to place the solar panels for maximum output?

The angle at which the solar panels should be fixed for maximum output depends on your location's latitude.
In general, the angle of tilt will lie between 9-12 degrees in the southern part of India and 25-30 degrees in north India. The angle decreases as the altitude of installation increases to nullify the impact of high-speed winds on the installation.

How should I go about the maintenance of my rooftop solar power system? What is the typical maintenance required for a solar power system?

A solar rooftop power system will deliver the full return on investment when it runs as smoothly as possible. This means periodic inspections of the individual components of the system. Timely intervention and check can prevent the threat of diminished output or downtime or a safety hazard. That is why it's important to get in touch with a reputed brand like PIXON to install your solar system and take care of all the necessary maintenance and care your system might need.

The true answer is – it depends. Most municipalities will not increase your property tax values due to a solar installation, but it’s worth checking with your town (or city) legislatures to be sure.

Will I see a difference in my lights or in how appliances run with solar, like on a generator?

Solar electricity is identical to grid power. So, you will never notice that the house is running on solar power. What you will see, of course, is a lesser or almost zero electricity bill to pay!

How many years do solar panels generate power?

Solar panels sold today don’t ever stop generating. While some of the wirings may need upgrading in future years, the panels remain useful for over 40 years. However, the generation capacity does reduce from the original over the years after the warranty-period.

What is net metering?

The solar panels produce a lot of energy during the day when the sunlight availability is at its peak. The house most likely won’t use all this solar-generated power. The excess solar power is fed back to the grid. At night, the extra units are taken back home from the grid. It works like a banking system.
An electric meter on your property is used to record how much energy your home or business uses every month. When you switch to solar energy, you’ll have a new electric meter replacing the old one. It works both ways, that is, it shows how many electricity units you consume from the grid when your solar panels aren’t generating electricity (like at night). It also shows how much energy your solar panels generated during the day. While you pay only for the extra units you consume than what your solar system generates. This is known as net metering.

Are solar panels difficult to maintain?

Solar panels are easier to maintain than your property, appliances, and maybe even your cell phone. That’s because solar panels have zero moving parts. The most you’ll have to do to maintain your solar panels is to make sure they’re free of dust, pollen, leaves, animal drooping and other debris. Anything that obstructs your panels will make them less efficient in energy production. You can read here in detail about how to clean your solar panels.

How does solar energy benefit the environment?

Solar power is a renewable resource, which means it is freely available. We would never have to dig for coal or refine other toxic energy sources just to keep the lights on. Solar energy reduces your carbon footprint by decreasing greenhouse gas emissions (which contribute to climate change). Since it doesn’t cause any pollution, it also means we’ll have less harmful pollutants in our air, land, and water.

Is solar energy used in Diverse Applications?

Yes. Solar energy is used for diverse applications and purposes. You can generate electricity (photovoltaic) or heat (solar thermal) from solar energy. Solar energy in the form of heat can be used in: solar water-heaters, cookers, calculators, etc. Solar energy (in the form of photovoltaic) can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited clean water supplies and to power satellites in space. Solar energy can also be integrated into the materials used for buildings.

Are there different types of technologies associated with solar power?

There are a variety of types of technologies associated with solar power. These technologies can be divided into two groups.

  • Solar Thermal Technologies – Use the sun’s heat. Example: solar concentrator power systems, flat plate solar collectors, and passive solar heating.
  • Solar Photovoltaics – Use the sun’s light or radiation. The photons of radiation are used to generate electricity through the photoelectric effect by using photovoltaic (also known as PV, that is, solar panels and or solar modules).

What is the duration of warranty on Solar Panels ?

Solar PV panels manufactured as per global standards are robust and can withstand the harsh weather conditions of nature. Generally, solar panels come with a product warranty of 10 years and a performance warranty of 25 years. With evolving tech, the performance warranty has increased to 30 years. So, you should not worry about the solar panels working and warranty period as they need the least maintenance and care.

Where can Solar Plants be installed ?

Solar panels can be installed almost anywhere, on the ground or rooftops. The rooftop systems can be installed at the roofs of residential, commercial complexes, housing societies, community centers, government organizations, private institutions, Industrial, etc.

In case of grid failure, is there any chance for electric shock to the person who is repairing it? What is “Island Protection” ?

In case the grid fails, the solar power must be fully utilized or disconnected from the grid immediately. This is done to stop current feeding on the grid, so as to safeguard any grid person/technician from getting electrocuted while working on the grid for maintenance and fixing. This feature is called "Island Protection".

How much roof area is required to set up the grid-connected rooftop solar system?

1 kW on-grid or grid-connected rooftop solar system generally requires 10 - 12 sq. meters (100 square feet) of flat and shadow-free area (preferably south-facing). Actual sizing, however, depends also on local factors of solar radiation, weather conditions, the shape of the roof, and type of solar panels used in the system.

Are all consumers eligible to install solar rooftop systems to avail net metering facilities?

Yes. All registered metered consumers coming under the jurisdiction of their respective State Electricity Board are eligible for installation of the solar system, based on their respective state policies.

What is net metering?

The solar panels produce a lot of energy during the day when the sunlight availability is at its peak. The house most likely won’t use all this solar-generated power. The excess solar power is fed back to the grid. At night, the extra units are taken back home from the grid. It works like a banking system.
An electric meter on your property is used to record how much energy your home or business uses every month. When you switch to solar energy, you’ll have a new electric meter replacing the old one. It works both ways, that is, it shows how many electricity units you consume from the grid when your solar panels aren’t generating electricity (like at night). It also shows how much energy your solar panels generated during the day. While you pay only for the extra units you consume than what your solar system generates. This is known as net metering.

Among "net metering" and "gross metering", what is preferred?

The net metering mechanism is more popular in India.

How critical is the quality of the structure on which the solar panels are mounted?

It is the most critical part as it acts as the skeleton for the entire system. A sturdy structure is mandatory as it needs to withstand strong winds and other natural forces. The structures are mostly made of galvanized iron, which is not only stronger than normal iron but also rustproof as well, making the solar power system last longer.
The structure for rooftop solar installation on a flat roof is completely different than that for a slanted roof. The height of your roof is another major factor that determines the composition and alignment of the structure. The quality of the material used has to be as per the MNRE (Ministry of New and Renewable Energy-India) specified norms.

Which direction should the solar panels face and why?

Solar panels need to face true south direction for maximum power generation. The reason behind it is that when the sun transits from east to west, it leans towards the south direction. Irrespective of which part of the year it is, the inclination will always be towards the south. Hence for the optimum harnessing of sunlight, the solar PV panels should ideally face south.
For example, a 7*12 roof that is due east or due west still achieves 77% of a system’s potential performance. More important than angle, generally, is shading. The solar panels should not experience shading from 9 am to 3 pm, year-round. Technological improvements such as micro-inverters can compensate for shading issues to some extent.

At what angle, one needs to place the solar panels for maximum output?

The angle at which the solar panels should be fixed for maximum output depends on your location's latitude.
In general, the angle of tilt will lie between 9-12 degrees in the southern part of India and 25-30 degrees in north India. The angle decreases as the altitude of installation increases to nullify the impact of high-speed winds on the installation.

How should I go about the maintenance of my rooftop solar power system? What is the typical maintenance required for a solar power system?

A solar rooftop power system will deliver the full return on investment when it runs as smoothly as possible. This means periodic inspections of the individual components of the system. Timely intervention and check can prevent the threat of diminished output or downtime or a safety hazard. That is why it's important to get in touch with a reputed brand like PIXON to install your solar system and take care of all the necessary maintenance and care your system might need.
