How does Coronado's climate affect this service?
Coronado has the strongest salt exposure in the county on solar panels. Direct ocean exposure on the Village and Shores blocks plus heavy gull traffic along the bay drive panel soiling faster than anywhere else the pro works. Quarterly cleaning is the working baseline for any property within a half-mile of the water; semi-annual only works on the inland edges.. Coastal homes occasionally show salt-spray hard water film that resembles standard mineral etching.
Is it really a stain or just dirt?
Regular cleaning makes it cleaner but the etching remains. The test: clean the panel with DI water and look at it backlit. If there's still a haze or rainbow shimmer, that's etching.
Won't acid damage my panels?
Concentrated acid would. The pro uses a dilute, panel-safe formulation that works in the 2-5 minute contact range, then a full DI rinse to neutralize. Manufacturers test panels against this method during certification.
