Solar panels convert sunlight into electricity through photovoltaic (PV) cells. This energy can be used immediately, stored in batteries, or sent back to the grid.

Yes! While solar panels produce less energy in cloudy weather, they still generate electricity. Efficiency may be lower compared to sunny days, but they continue to function.

Most solar panels last 25-30 years and continue producing energy even after that, though at a slightly reduced efficiency.

Minimal maintenance is needed. Cleaning them occasionally to remove dust and debris ensures optimal performance. Many systems come with warranties and monitoring options.

The cost varies based on system size, location, and incentives. On average, a residential system ranges from $10,000 to $30,000 before incentives.
