How does Chula Vista's climate affect this service?
Chula Vista has extremely high new-construction solar adoption density in the Otay Ranch, EastLake, and Rancho del Rey master-planned communities. Layered film from coastal salt to the west and Otay Mesa industrial dust to the east drives quarterly cleaning as the working baseline. Largest residential solar inventory in South County.. A good pro accounts for local conditions on every job.
How is soft wash different from regular pressure washing?
Pressure washing is 1,500 to 4,000 psi water blast. Soft wash is under 60 psi with a brush doing most of the work. Pressure washing can crack the anti-reflective coating, force water past the panel seal into the junction box, and void warranties. Soft wash is the only method most manufacturers explicitly permit.
Why deionized water?
DI water has zero dissolved solids. As it dries on the glass it leaves no mineral spots. Tap water in San Diego is hard, it dries to a calcium film that bonds to glass and reduces transmission permanently. The pro carries a truck-mounted DI tank and check ppm before every job.
