Solar panel cleaning in San Luis Obispo County
Purified-water, chemical-free cleaning for residential rooftops and commercial arrays. Get back the output you paid for.
Ali's Star cleans solar panels for homes, businesses and agricultural properties across San Luis Obispo County. Our crew uses dedicated solar cleaning equipment, deionized water and soft brushes, so panels are cleaned safely, without residue and without voiding warranties. Dust, pollen, bird droppings and ash reduce the light reaching the cells; routine cleaning restores a measurable share of lost production, especially after dry summers and fire season.

Solar Panel Cleaning questions
How often should solar panels be cleaned on the Central Coast?
Once or twice a year for most homes. Properties near agriculture, dirt roads, wineries or the coast collect dust, pollen and salt faster and may benefit from cleaning every 4 to 6 months.
Does cleaning really improve output?
Yes. Soiling routinely cuts production, and hot spots from bird droppings can shorten panel life. Cleaning restores output; we document it with before-and-after photos.
What do you use to clean solar panels?
Soft brushes and deionized water. No harsh chemicals or abrasives, which protects the anti-reflective coating and keeps warranties intact.
Is it safe to walk on my roof?
Our technicians are trained for roof work and use water-fed poles to minimize walking on panels and roofing.
How much does solar panel cleaning cost?
Priced per panel with a minimum per visit. Send your address and panel count (or a photo of the array) and we quote within one business day.
