Soft Wash in Santee, CA.

Soft Wash for Santee homes, done by experienced San Diego County technicians. Soft wash means three things: low pressure (under 60 psi at the panel), a soft horsehair or microfiber brush, and a pure deionized water rinse with zero detergent. It's the only cleaning method that doesn't risk voiding your panel warranty, and it works..

Santee: Santee has very high residential solar adoption density in the Carlton Hills and Sky Ranch tracts. 100-110°F summers, hard-water sprinkler overspray on the newer tract stock, and Santa Ana wind-event dust deposits drive quarterly cleaning as the working baseline.

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.
