Commercial Solar Panel Cleaning Sacramento | Restore Array Output

› Quick Answer

Wash Works cleans commercial and residential solar arrays across Greater Sacramento using a pure-water fed pole system — deionized water and soft-bristle brushes, no chemistry, no pressure on the cells. Sacramento's farm-belt dust and pollen can cost a commercial array 15–30% of its annual output. Recurring quarterly or bi-annual programs available for commercial portfolios; residential arrays typically take 30–90 minutes. Free quotes — (916) 404-0288.

FAQ

Solar Cleaning FAQ.

Don't see yours? Call (916) 404-0288 — we're happy to talk it through.

Studies in dry, dusty climates like Sacramento's Central Valley show 15–30% output loss between cleanings. The actual figure depends on how much pollen, dust, and bird traffic your array sees.

Not when done correctly. Wash Works uses pure deionized water and soft-bristle brushes — no chemistry, no pressure, no abrasive cleaning. All major panel manufacturers explicitly allow this method.

In Sacramento, every 6–12 months is the sweet spot. Heavy-tree-cover homes and farm-edge properties may benefit from quarterly cleaning.
