Frequently Asked Questions
How often should I clean my solar panels?
Most homes benefit from cleaning 1–2 times per year. Commercial arrays and properties near farms, freeways, or coastal areas often need quarterly service.
Will cleaning void my panel warranty?
No. We use manufacturer-approved methods — soft brushes and purified water — that fully preserve your warranty.
Do you use chemicals?
No harsh chemicals. Purified (deionized) water lifts dirt safely and leaves zero residue behind.
How much does it cost?
Every property is different. Most residential jobs fall in a predictable range — we’ll give you a free, firm quote before any work begins.
Are you insured?
Yes. We’re fully licensed and insured, and our crews are trained in rooftop safety and fall protection.
