    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 clean solar panels without water too. For this, you can use soft micro-fibre-based cleaners. These are easily available offline and online. Many of them also come with extendable rod lengths to increase the extent of these dry cleaning equipment.

    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.

    In India, only a few companies offer direct sales of solar panels to customers through e-commerce platforms. However, due to the availability of certain panel manufacturers, purchasing panels online is possible. The country has around 130 solar panel manufacturers, with approximately 95 registered under MNRE’s ALMM (Approved List of Models and Manufacturers).

    Most module manufacturers do not sell solar panels directly to customers for rooftop solar projects. Instead, these panels are typically supplied by vendors who handle project installation. If you have a preference for a specific solar panel brand, you can request your vendor to source those panels or compatible inverters to meet your requirements. Vendors often have exclusive arrangements with manufacturers to supply these products. However, it is worth noting that many vendors offer only a limited selection of panel brands, restricting customer choices.

    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.

    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.

    One of the benefits of using solar panels for power generation is that unlike thermal energy, it does not emit green house gases during electricity generation. However, a latest study hinted a minor rise in local temperatures due to the use of inefficient solar panels.
