What determines your cleaning frequency?

  • Environment: Dust corridors, coastal salt, construction sites, and tree pollen increase buildup.
  • Roof access & tilt: Low‑tilt panels shed less water and may spot more often.
  • Local weather: Storms and wildfire ash can warrant an extra visit.

Recommended cadence by setting

Setting Suggested cadence Notes
Suburban / typical dust 6–12 months Good all‑around baseline.
Near construction or agriculture 3–6 months Extra dust and pollen.
Coastal salt spray 3–6 months Prevent corrosive film.
After wildfire ash or storms As needed Restore production quickly.

Signs it’s time to schedule

  • Visible haze/spots that don’t rinse off with rain.
  • Noticeable drop in output on clear days vs. prior months.
  • Bird activity/debris around panel edges or gutters.

Why a bi‑annual plan helps

Staying on a predictable schedule keeps panels efficient and lets technicians catch minor issues early. We also offer 25% off the second cleaning when you book it with the first.

Why professional cleaning?

Pros use deionized (DI) water and soft‑bristle brushes—no harsh detergents or pressure washers—leaving panels spotless and coatings safe.

Bottom line

Most homes thrive with a 6–12 month cadence; step up frequency in dusty, coastal, or high‑pollen areas. If your output has dipped or panels look hazy, it’s time.

Every site is unique. Quotes may change based on access, pitch, or heavy soiling. See our Terms.
