Solar Panel Installation in Kolkata

Yes, solar panels still generate electricity on cloudy days, though output is lower compared to bright sunny days since less sunlight reaches the panels. On rainy days, generation drops further, but rain also helps naturally clean dust off the panels, which can improve performance once the sun is back out.

Yes, most parts of India receive ample sunlight through the year, making it one of the most favourable countries for solar energy generation. Regions with higher average sunny days naturally see better solar output, but even areas with moderate sunlight can benefit from a well-designed system.

Solar panels are built to be weatherproof and are designed to withstand rain, wind, and moisture without damage. However, extreme weather like hailstorms or very high winds can pose a risk, which is why panels are mounted with sturdy structures and, where needed, protective measures during installation.

Yes, solar panels can be installed on sloped or tiled roofs using mounting structures designed specifically for that roof type. The installer adjusts the mounting angle to make sure the panels still capture optimal sunlight, even if the roof itself isn't flat.

On average, 1 kW of solar capacity requires around 80-100 sq. ft. of shadow-free roof area, though this can vary slightly depending on the panel type and efficiency used. This is a useful starting point to roughly estimate how much of your roof space you'd need before going for a bigger system.
