Solar Panel Cleaning in San Francisco, CA
Restore your solar panels to peak efficiency with professional cleaning.
About Our Solar Panel Cleaning Service
Dirty solar panels can lose 20-30% of their energy output. San Francisco's combination of fog residue, bird droppings, pollen, and urban dust creates a film that significantly reduces panel efficiency. Our specialized solar panel cleaning uses deionized water and soft brushes -- never harsh chemicals or abrasive tools -- to safely restore your panels to peak performance without voiding manufacturer warranties.
What's Included
Our Process
Panel Assessment
We inspect your panels for soiling level, bird damage, and any physical issues that need attention.
Gentle Cleaning
Using deionized water and soft, non-abrasive brushes, we clean each panel thoroughly without scratching.
Spot Treatment
Stubborn spots from bird droppings or tree sap get targeted treatment with panel-safe solutions.
Final Rinse
A deionized water rinse leaves panels spot-free with no mineral residue. We verify all panels are clean.
