What’s Included
Safe, thorough cleaning that restores your panels to peak performance:
- Purified water system: no chemicals, no residue, no streaks
- Bird dropping & grime removal: stubborn buildup safely cleared
- Performance check: we make sure panels are spotless and unobstructed
Cleaning pays most where rain does not do the job. A UC San Diego study of 186 California solar sites found that ordinary dust cost only 7.4% after a 145-day dry spell, but that bird droppings block essentially all light and do not wash away in rain, and that low-tilt arrays and homes downwind of highways or farm fields lose more.
Our Process
- Inspect: We check your panels for buildup, debris, and any damage
- Clean: Purified water + soft tools safely remove everything without scratching
- Verify: Final check to make sure every panel is clear and producing at full capacity
Pricing

FAQ
Do dirty panels really affect energy output?
Yes, but how much depends on what is on the glass. UC San Diego measured a 7.4% loss from ordinary dust after 145 dry days in California, while bird droppings block essentially all light where they sit and do not rinse off in rain. Coastal salt film and wildfire ash can cling the same way.
How often should solar panels be cleaned?
It depends on exposure: roughly every 2 to 4 months for coastal and near-beach homes, every 4 to 6 months inland, and every 6 to 12 months for low-soiling roofs, adjusted by what the glass and your production data show. Our guide on how often solar panels should be cleaned breaks the interval down by coastal, inland, and foothill exposure.
Do you use chemicals?
No. We use purified water only, which is safe for your panels, your roof, and the environment.
Is it safe for the panels?
100%. Our methods are designed specifically for solar panels: no abrasives, no pressure washing.
Can I clean my solar panels myself?
If the array is on a single-story roof you can reach from the ground, often yes. Use cool panels, low-pressure water, a soft brush, and purified water, and check your panel manual before using any soap. Our guide on how to clean solar panels on a roof compares what REC, Qcells, and First Solar allow. If you would need to climb onto the roof, book a visit instead.
Can I combine this with window washing?
Yes. Many clients schedule both together. We're already on-site, so it saves time and money.
