Solar panel cleaning
When you need it
Panels need cleaning when dust and pollen build up and block the sun. When less sun gets through, the panels make less power.
How it's done
Panels get cleaned with a soft brush and filtered water: a light scrub and a rinse. Filtered water dries without spots, so nothing is left on the glass. Depending on the roof, it gets done from the ground, a ladder, or the roof.

Price
Solar panel cleaning is quoted in person. It depends on how many panels and how easy they are to reach.
