Solar Panel Cleaning in Greater Sacramento

Solar panels lose efficiency as dust, pollen, bird droppings, and hard-water spotting accumulate on the glass and block light from reaching the cells. Cleaning restores that lost transmission. We clean the panel face with deionized (zero-mineral) water so it dries spotless — no new mineral film left behind to undo the work.

Panels are cleaned with soft, non-abrasive tools and low pressure to protect the glass and the anti-reflective coating — never harsh brushes or high pressure that could scratch or void a panel warranty. We work from the roofline safely and time cleaning for cooler parts of the day, since spraying water on glass that is hot in full sun risks thermal stress.

Through a Sacramento Valley summer, panels can go months without rain to rinse them — and a measurable share of your production disappears under the film. A periodic clean pays for itself in recovered output, and it is the kind of upkeep that is easy to forget until you see the difference on your next bill.
