How does Lemon Grove's climate affect this service?
Central San Diego has dense urban tree pollen and mild marine influence. Lemon Grove arrays typically need cleaning every 9 months — sooner if you are under heavy bird traffic from a neighboring property or near a park.. We account for local conditions in every job.
How often should solar panels be cleaned in San Diego?
Twice a year for most homes. Coastal homes with heavy marine layer or homes near agriculture, dirt roads, or trees with heavy bird traffic should plan on quarterly. Inland homes with low pollen and no nearby trees can sometimes go 12 months between cleanings if rainfall is normal.
Why not just hose them off?
Tap water in San Diego is hard. It dries to a mineral film that bonds to the glass and actually blocks more light over time. We use deionized water that leaves zero residue. We also use a soft brush — high pressure can void your panel warranty and damage the anti-reflective coating.
