How often should panels be cleaned in the Central Valley?

Twice a year for most homes — spring after pollen and fall after harvest dust. Homes near orchards, dairies, or dirt roads often do best on a quarterly schedule.

Will cleaning void my panel warranty?

No. We use soft brushes and deionized water with no soaps, abrasives, or pressure washers on the glass, which keeps you inside manufacturer guidelines.

How much output will I get back?

Heavily soiled arrays commonly recover up to 30% of lost production. Lightly dusty systems typically gain 5–10%.

Do you need access to water or power?

We bring our own deionized water system. An outdoor spigot helps, but we can work without one.

Solar Panel Cleaning

Solar panel cleaning that pays for itself.

Central Valley dust, pollen, ag spray, and bird droppings quietly cut your production every month. We restore your array with soft brushes and pure deionized water — no soap, no scratches, no residue.
