Commercial Solar Panel Cleaning
Dusty panels make less power. We clean arrays gently, in the cool part of the day, so they produce what they were sold to produce.

How often should solar panels be cleaned?
In dry, dusty parts of Southern California, clean solar panels once or twice a year, and quarterly near freeways, farmland or construction. Panels are cleaned with soft brushes and no harsh chemicals, in the cool part of the day.
Panels in the Inland Empire sit under months of dust, pollen and Santa Ana wind with almost no rain to rinse them. Add bird droppings and a film from nearby freeways, and output drops without anyone noticing.
A customer thanked us in a review for cleaning their solar panels along with the rest of the job. It is a small add-on that pays for itself.
What we clean
- Rooftop arrays on commercial buildings
- Solar carports and canopies
- Arrays on HOA and multi-unit buildings
- Bird droppings and nesting debris around panels
Not sure it will come clean? Ask for the free on-site demo. We wash a test patch on your worst concrete and you decide after you see it.
Gentle on purpose
Panels are glass with a coating, and pressure or harsh detergent can damage both. We use soft brushes and no harsh chemicals, and we clean early or late so cold water never hits hot glass.
How often
Once or twice a year suits most arrays in dry parts of Southern California. Sites near freeways, farmland or construction get dirty faster and benefit from quarterly cleaning.

Solar Panel Cleaning FAQs
Questions we get before every job
Not answered here? Call or text (714) 867-3418.
Does cleaning solar panels really increase output?
Dirt blocks light, so a dirty array produces less. How much you gain depends on how dirty the panels were. In dusty inland areas with little rain, the difference after cleaning is usually easy to see in the monitoring data.
Can pressure washing damage solar panels?
Yes, which is why we do not pressure wash them. Panels are cleaned with soft brushes and a gentle rinse.
How often should commercial solar panels be cleaned?
In dry, dusty parts of Southern California, once or twice a year is common. Arrays near freeways, farms or construction may need it more often.
