How does Harbison Canyon's climate affect this service?
Harbison Canyon is in the extreme fire-risk zone between El Cajon and Alpine, solar arrays here serve battery-backed off-grid-capable systems on most properties, and post-fire ash cleaning is a recurring emergency service driven by the area's 2003 Cedar Fire history and ongoing wildfire exposure.. 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.
