Solar panel cleaning

Keep your panels producing at 100%.

Dust, pollen, bird droppings, and sprinkler residue cut solar output 5–20% — a few hundred dollars a year for most California homes. We clean it back the right way, with deionized water and a soft-bristle hand wash, and we show you the lift on your inverter data.

What's actually robbing your output.

Three things cost California solar owners the most kWh every year. All three are fixable in a couple of hours.

5–10%

Typical output loss

Dust & ash buildup

California's dry summers + Central Valley winds + fire-season smoke leave a haze on glass that scatters sunlight before it ever reaches the cell.

Up to 25% per panel

Typical output loss

Bird droppings, pollen & lichen

Localized hot spots — even a single dropping shades a string and can drag a panel's output to zero. Lichen and moss eat the anti-reflective coating over time.

8–15%

Typical output loss

Mineral residue from sprinklers

Hard-water sprinkler spray bakes calcium into the glass. Once it etches, no amount of rain washes it off — only a hand clean with the right water and tools.

What every clean includes.

Same six steps on every visit, whether it's a one-time clean or your tenth quarterly. No upsell-after-the-truck-arrives pricing — what you see here is what we do.

Honest pricing. Three plans.

Pick what fits — one clean to test it, twice a year for most homes, or quarterly if you're near ag, trees, or smoke.

One-time clean

A single visit — full clean plus pre/post performance check and inspection. Best for first-time customers checking whether their panels are actually losing output.

Best for

New customers, before-sale evaluations, post-fire-season catch-up

  • Full hand wash, all panels
  • Pre/post inverter performance check
  • Mount + wiring visual inspection
  • Photo report within 24 hours

Starting at $179 — typical 6–12 panel home

One-visit pricing scales with array size, roof pitch, and access. Quoted in writing before we book.

Recommended

Bi-annual plan

Two cleans a year — typically spring (post-pollen) and fall (post-fire-season). The sweet spot for most California homes.

Best for

Most California homeowners

  • Two cleans/year on a fixed schedule
  • Priority scheduling — booked first when crews route your area
  • 10% off any panel or wiring repair we find
  • Photo + inverter performance report each visit

Starting at $299/yr

Locks in pricing for 12 months. Cancel anytime before the second visit for a 50% refund.

Quarterly plan

Four cleans a year. The right call if you live near agriculture, under heavy tree cover, in a wildfire-prone area, or on a coastal salt-air corridor.

Best for

Ag-adjacent, fire-prone, tree-canopy, or coastal homes

  • Four cleans/year — every ~90 days
  • Priority scheduling on every visit
  • Quarterly performance trend report (kWh delta over time)
  • 15% off any panel or wiring repair we find

Starting at $479/yr

Best per-clean rate. Plan auto-renews unless you cancel; we email a reminder 30 days before each renewal.

Pricing varies with array size, roof pitch, access, and routing. All quotes are written, fixed, and good for 30 days. No hourly surprises.
