How does Bonita's climate affect this service?
Bonita is semi-rural equestrian-property territory in the Sweetwater Valley between Chula Vista and National City. Larger lots, equestrian fencing, moderate solar adoption from the 2018-2022 wave. Semi-annual cleaning is the working baseline; quarterly on equestrian properties with barn-mounted arrays.. We account for local conditions in 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. We carry a truck-mounted DI tank and check ppm before every job.
