Common questions.
All our brushes and everything we touch your panels with are specifically made for solar panel cleaning. They have non-abrasive bristles that don't scratch or damage your panels — only clean them.
No. All our methods follow manufacturer guidelines. We use DI water and if chemicals are needed, they are all approved for solar panel cleaning.
Deionized (DI) water is exclusively used and has minerals removed, so it leaves zero residue, no spots, no film. We test our water daily with a PPM meter to ensure our DI systems are working properly.
Most properties in San Diego benefit from 2–4 cleanings per year. Coastal areas and locations near roadways or desert environments skew toward the higher end.
