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

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.
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?
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.
