Solar is a simple, minimum-maintenance technology. Unlike other energy technologies, solar PV contains no moving parts. This means it’s not likely your equipment will fail. You should not have to replace your panels at all during their lifetime. Wiring is the part of solar PV that most commonly requires maintenance because squirrels and other animals may tamper with it. Even in those cases, damage tends to be minimal. Solar panels do not need to be washed, as rain and snow naturally clean them. We do not recommend climbing up to your panels to wash them.
