    Team of Solar Faqs | Answer on January 22, 2025 at 2:51 pm

    Yes,. This is a common practice in India. Even for the same technology—such as 540 Wp mono-PERC solar modules—different companies offer varying prices. Premium brands often charge higher rates due to their strong market reputation, extensive domestic and global certifications, and other factors.

    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.

    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.

    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.

    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.
