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.

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.
