Solar Panel Cleaning FAQs
How are solar panels cleaned?
We inspect the panels, clean them with a non-abrasive soft-bristle brush and rinse with de-ionized water, which leaves no residue behind.
Why use de-ionized water?
De-ionized water is purified water with the minerals removed, so it dries without leaving the spots and film that ordinary tap water can.
How often should solar panels be cleaned?
It depends on your surroundings. Dust, pollen, bird droppings and nearby farmland all add up, and many homeowners clean once or twice a year. We can recommend a schedule once we see the system.
How much does solar panel cleaning cost?
Our online estimate prices the job by the number of panels, with separate tiers for single-story and multi-story roofs, starting at $185 for 5 to 10 panels on a single-story roof.
Is it safe for my panels?
We use a non-abrasive brush and purified water, with no harsh chemicals described in our process, so the surface is treated gently.
