Quarterly cleaning is the safer baseline.. East County summers bring desert dust from the I-8 corridor and Anza-Borrego pull-throughs.

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. Deionized water leaves zero residue. A soft brush is the safe tool, because high pressure can void your panel warranty and damage the anti-reflective coating.
