How often do solar panels need cleaning?

• We suggest cleaning twice or 3 times a year, with more frequent cleaning (every 3–6 months or even quarterly) if you live in dusty, pollen-heavy, or bird-prone areas—or after wildfire ash or construction dust.
  

Will cleaning void my warranty or impact insurance?

• Regular cleaning generally does not void warranties; in fact, many manufacturers require routine cleaning to maintain coverage. Neglect may void warranties or insurance claims related to dirt or debris buildup.
