    Generally, rooftop solar offers an ROI of over at least 20% in most markets today. Hence, it gives a payback period of about 4-5 years. Even without any subsidy or incentives, chances are, it will pay back your investment in 7 years or less with good maintenance and a net metering regime.

    The overall rooftop solar systems in India had been limited. However with the launch of PM Surya Ghar scheme with more capacities and easier application process, the residential rooftop solar system is likely to increase.

    Yes. You can use non-abrasive soft clothes or duster to clean the solar panels to remove upper layer dust. Try to do it in an interval of 5-7 days, based on the dust levels to avoid unecessary wearing chances. You can use water for clearning twice a month to remove hard to remove layers of dust withRead more

You can use water for clearning twice a month to remove hard to remove layers of dust with the help of soft-bristle brushes. Keep it mind not to use high pressure water.

    The efficiency of solar cells (or solar modules at large) means the capacity of the item to capture the sunlight falling onto it and convert it into electrician energy. It is calculated by the total electrical output of the solar cells, divided by the incident solar power input under standard test conditions. The figures are then multiplied by 100. Different type of solar cells produce different level of efficiency based on the technologies used. For example mono-PERC cells are more efficient than polycrystalline cells. Similarly, TOPCon cells are more efficient than mono-PERC cells.

    If you are using UPS and battery for power backup, a new rooftop solar connection will not hamper the functining of your batteries and power backup. It will work like it used to work before the installation of rooftop solar.
