TIP: Solar panel cleaning

Collyn Rivers

Except in rainy areas solar panels need cleaning from time to time. Use a tiny amount of washing up detergent, a cloth and warm, clean water. Rinse, using a trace of detergent in otherwise clean water. Let solar modules dry naturally.


Never wipe them dry and especially do not polish them. Doing either builds up an electrostatic charge that attracts dust. A trace of detergent in the rinsing water acts and an effective anti-static barrier.
