Questions

Solar Panel Cleaning FAQs

How much output can dirty panels lose?
It depends on how much buildup has accumulated, but even a light layer of dust and grime can noticeably reduce how much power your panels produce, cleaning restores that lost output.
Will cleaning damage my panels or their coating?
No, we use pure, deionized water and soft, non-abrasive tools designed to protect the glass and anti-reflective coating.
Do you clean residential and commercial arrays?
Yes, we clean both residential rooftop systems and commercial arrays.
How often should solar panels be cleaned?
We recommend cleaning solar panels twice a year to keep them performing at their best.
Is roof access included and safe?
Yes, our insured technicians handle roof and ground-mount access safely as part of the service.
Will cleaning extend the life of my solar panels?
Keeping panels free of dust, grime, and buildup helps prevent long-term wear on the glass and coating, so regular cleaning is one of the easiest ways to protect your investment.
Can I clean my solar panels myself?
You can, but the wrong tools or technique can scratch the glass, damage the anti-reflective coating, or void your manufacturer's warranty. Our insured technicians use pure water and soft, non-abrasive tools specifically to avoid that risk.
