How does Shelter Valley's climate affect this service?
Shelter Valley is extreme desert solar at the Anza-Borrego edge. 105°F+ summer heat, ubiquitous off-grid solar adoption driven by remote location and minimal grid infrastructure. Cabin and mobile home stock dominates. Quarterly cleaning during cooler months is the working baseline.. A good pro accounts for local conditions on every job.
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.
