How does High Tide Window Cleaning clean solar panels?
High Tide Window Cleaning cleans solar panels by hand with soft-bristle brushes and deionized (purified) water, then rinses the panels and frames spot-free. The crew never uses high pressure on solar glass, because pressure can force water past panel seals and scratch the surface. Pricing is $12 per panel, adjusted for stories and roof access.

Purified water dries without mineral spots that block sunlight.
Panels and frames

Why no pressure washer
Why shouldn't solar panels be pressure washed?
High-pressure water can push past panel seals, scratch the glass coating and put a panel warranty at risk. Tap water also dries into mineral spots that block light. A soft brush and deionized water avoid both problems.

Questions
Solar panel cleaning questions
How much does solar panel cleaning cost in San Luis Obispo County?
High Tide Window Cleaning charges $12 per panel for solar panel cleaning in San Luis Obispo County and northern Santa Barbara County. Steep or second-story roofs add an access charge, set at a free in-person quote.
Why don't you pressure wash solar panels?
High pressure can force water past panel seals and scratch the glass surface, so High Tide Window Cleaning cleans solar panels with soft-bristle brushes and deionized water instead.
How often do solar panels need cleaning?
Every 6 months for most inland arrays, and once or twice a year near the coast. The full breakdown is in the guide how often to clean solar panels on the Central Coast.
Do you clean ground-mounted solar arrays?
Yes. High Tide Window Cleaning cleans roof-mounted and ground-mounted solar arrays, including arrays on rural properties and ranches, at the same $12 per panel rate.
Do dirty solar panels really produce less power?
Yes. Dust, pollen and bird droppings block sunlight from reaching the cells, which lowers energy output. How much depends on how dirty the panels are, so many owners compare their monitoring app before and after a cleaning.
