    Yes, Mounted solar panels are available in the market and are being used widely. BIPV (Building Integrated PV) for instance refers to panels that are used as substitutes for windows. Similarly, solar panels are being used on balcony’s now, besides for fencing as a solar fence. These options, while not optimum in terms of generation, do help to provide you with a solar energy source in well irradiated areas.

    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.

    Solar panels work at full efficiency at around 25˚C. So even in winter they work fine. Even at lower temperatures, they typically perform well if sunshine is good. Colder regions, with their lesser issues of dust are also beneficial for solar generation. Remember, solar energy is generated by lightRead more

    Solar panels work at full efficiency at around 25˚C. So even in winter they work fine. Even at lower temperatures, they typically perform well if sunshine is good. Colder regions, with their lesser issues of dust are also beneficial for solar generation. Remember, solar energy is generated by light falling on solar panels, not by heat. So really hot temperatures offer no benefit to users.

    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.

What is the ROI of solar panels over its lifetime?

    Team of Solar Faqs | Answer on May 6, 2024 at 5:51 pm

    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 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.

    Several solar companies provide Operations & Maintenance (O&M) service for the initial 5 years as the major components like solar panels and solar inverters provide warranty for this period. Some solar companies give regular monthly cleaning in a package during the time of installation either for a period of 5 years and even after that. There are also some companies dedicated to the O&M services at a cost. However, there are also several non-professional companies that have flourished. Some of them are seen using high pressure water and detergents to clean the solar panels. So please choose your O&M partner based on their team strength and background.
