Professional Solar Panel Cleaning Services

Protect and maintain your solar investments with safe and high-quality cleaning.

  • San Jose and South Bay Area

You solar panels need a detailed cleaning because rainwater alone or a rinse with a garden hose is not enough to remove buildup that affects performance. 

To properly clean them, you have to agitate the dirt by scrubbing it off with a soft bristle brush.

At CA Wash Pros, we clean solar panels according to manufacturer guidelines. We use our portable water purification system and water-fed pole brush. We don’t apply any chemicals.

What Our Clients Say

Ornit Szwarcbord
★★★★★
Chris from CA Wash Pros has been cleaning my gutters, windows, and solar panels for several years at my home in San Jose, and he always does an excellent job. He is very professional, reliable, and pays great attention to detail. His prices are always fair, and the service is consistently excellent. It’s hard to find someone who provides such good value for the money. I highly recommend Chris and CA Wash Pros!

★★★★★
We got our gutters and solar panels done. Even though the weather was on and off rain Chris made plans to come out to work. Service was great. I have a very tall 2 story home and he got up there and took care of years worth of debris and leaves from a tree we had to cut down. He let me know I had a pigeon problem and did his best to clear it out for us. Cleaned up our solar panels and the roof from the birds. Chris was great to work with. The quality of his work and his customer service is very refreshing.

★★★★★
I am beyond thrilled with CA Wash Pros. They responded very quickly to my questions and came today to do the jobs. They cleaned and repaired my rain gutters, washed my solar panels and washed the outside of 30 windows and the screens on a two story home. Chris, the owner, was very pleasant as was the young man that worked with him. They worked tirelessly and what I really appreciated was that they took pictures of everything they did on my roof so that I knew in fact that they actually did the work. They sent reminders ahead of the visit and arrived precisely when they said they would. I very highly recommend them.

★★★★★
I found Chris on Yelp and contacted him after reading his wonderful reviews. He didn't disappoint. Chris was exceptionally responsive with all his communications, quoted a reasonable price and held to it, showed up on time, and went the extra mile. He is meticulous and our windows and solar panels have never looked cleaner. I will definitely have Chris return next year.

How To Maintain Your Solar Panels

Regular Cleaning: We recommend getting your solar panels cleaned at least once a year. You may need more frequent cleanings if your property is in an industrial zone, surrounded by many trees, or under high humidity levels.

Inspections: Check for significant declines in the performance and call a solar professional for an inspection.

Trim Nearby Trees: Nearby branches cast shade that promotes humidity and moss growth. Trim excessive branches to prevent buildup that could lead to long-term damage.

Bird Proofing Solutions: Birds fill your panels with droppings. Protect your solar panels with expert bird-proofing solutions.
