How does Coronado's climate affect this service?
Coastal salt air is the hardest environment in the county on outdoor condensers — copper corrosion on coil fins and fastener rust cut equipment life nearly in half. In Coronado we use coastal-rated condensers, corrosion-resistant stands, and annual spray-rinse maintenance to push service life back toward spec.. Coastal homes accumulate marine layer salt film fast — especially from May through August during the foggy mornings.
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.
