Solar Panel Cleaning
Get back the output dust is stealing. Serving Goleta, Santa Barbara, Montecito & Summerland — insured, on time, rated 5.0★.
What we do
Solar panels are sold as self-cleaning, and mostly they aren't. Between our long, rain-free summers, grove pollen, dust, and bird droppings, a film builds on the glass that blocks light before it ever reaches the cells — and heavy soiling can quietly shave a real chunk off an array's output before you notice the dip on your bill. Goleta Pressure Washing cleans panels with purified, deionized water and soft tools that won't scratch the glass or void the manufacturer's warranty. On the sun-soaked South Coast, where panels work hard for nine months without a drop of rain to rinse them, production usually snaps right back once the film is off. It's a natural pairing with a roof cleaning — if we're already up there working on the roof, the panels are right there.
We clean with deionized, purified water and soft brushes — no harsh detergents, no abrasive pads, and nothing that would scratch the anti-reflective coating or give a manufacturer a reason to deny the warranty. Purified water is the key: it dries without leaving the mineral spots that tap water and a squeegee leave behind, which on glass angled at the sun is its own kind of soiling.
Most arrays are reached with a water-fed pole from a safe position rather than by walking on the panels, which protects the panels, the roof, and us. Where a roof does have to be walked, we already know how to do it carefully from the roof-cleaning side of the business.
Bird droppings and baked-on mineral spots get the most attention, because those are the deposits that block the most light and set the hardest under the sun. A season of grove pollen and dust rinses off; the droppings need working.

Patio Roof Cleaning
Grant and Zack did a great job on my patio roof. Looks like it's brand new. I would highly recommend these hard-working guys.

Full Exterior Wash
We are extremely satisfied with Grant's power washing. From the walls to the windows, patio tiles and pavers, and the driveway — they all look bright and clean now! The eaves were covered in cobwebs and dirt. All gone! Highly professional.

Questions
Solar Panel Cleaning FAQs
Does cleaning solar panels actually increase output?
Yes, often noticeably. A film of dust, pollen, and bird droppings blocks light from reaching the cells, and heavy soiling can cut output by a real margin. Cleaning removes that layer, and on our sunny, dry-summer coast production typically rebounds right after — you're getting back power you were already paying to lose.
Will cleaning void my solar warranty?
Not the way we do it. We use purified water and soft brushes with no abrasives and no harsh chemicals, which is exactly what panel manufacturers recommend. It's aggressive scrubbing and the wrong cleaners that cause trouble and complaints — never gentle, purified-water cleaning.
How often should solar panels be cleaned here?
Once or twice a year suits most South Coast homes, where the long dry season lets dust and pollen build up for months with no rain to rinse it. Homes near the Goleta groves, under heavy trees, or with a lot of bird activity often benefit from more frequent cleaning.
