Common questions

Solar Panels FAQs

How often should solar panels be cleaned?

Once a year for most installations; twice a year for systems near trees, agricultural areas, or under heavy bird traffic.

Will cleaning void my panel warranty?

Not with our method. We use deionized water and soft brushes, which is what every major panel manufacturer recommends.

Can dirty panels really reduce output that much?

Yes. Independent studies have shown 5–25% output loss from soiling, especially in dry inland areas like Sacramento.
