The Roseville problem
What Roseville's dry season does to your system output
From late May to October, rain is a rumor here. Dust, pollen, and bird droppings accumulate with nothing to wash them off, and energy production drops a little more each week. NREL data puts worst-case soiling losses at 21% on residential arrays in dry climates. Max efficiency is not a luxury in a Roseville summer; it is exactly when your panels earn the most, and a film on the glass takes its cut off the top.
Two local aggravators make it worse. Sprinklers running against the roofline leave hard water spots and mineral deposits that ordinary rinsing cannot touch. And mature landscaping in older neighborhoods drops tree sap that grabs every particle floating by.
Performance restoration is measurable: clean panels report the difference on your inverter app within a day or two. Run your numbers in the solar cleaning payback calculator if you want the math before you call.
Our process
Our process: inspect first, clean second
Every job starts with an inspection of all the solar panels, then the cleaning itself, done the way panel manufacturers specify in their own manufacturer guidelines:
- Inspect all the solar panels. Broken glass, cracked cells, micro-scratches, failed seals: if we find a problem, we address it with you before we start any work. Nobody should pay to have a damaged panel washed.
- Purified water only. Our deionized water system produces a spot-free rinse with zero residue.
- Panel-safe brushes on a water-fed pole. This is a soft wash for glass: no abrasive pads, which cause the micro-scratches that permanently scatter light.
- Streak-free cleaning verified. We make sure there's no streaks before we leave. That is the satisfaction guarantee, in full.
Want before and after photos of your own roof? Ask when you book and the crew will document the job.
We never use pressure washing on solar panel washing jobs. We own the pressure washers; we know precisely what they do to a panel seal. That keeps your warranty compliance intact, which is worth more than the cleaning itself.
What it costs
Roseville solar panel cleaning prices
Upfront pricing, current as of July 2026. The estimate we give is built from panel count and access, nothing hidden:
| Job | Price |
|---|---|
| Solar panel cleaning | $15 per panel, $200 minimum |
| Difficult roof access or heavy buildup | +20% |
| Very difficult access, very heavy buildup | +35% |
| First 15 round-trip miles | Included |
| Bundle gutter cleaning, window washing, or other exterior cleaning | Save about 10% |
A typical 22-panel Roseville two-story runs around $330.
July 2026 special
$30 off plus a free roof and gutter inspection with every solar panel cleaning booked by July 31. Mention code SOLAR30.
Roseville logistics
HOAs, gate codes, two-story roofs: we deal with it
Plenty of Roseville homes sit behind gates or under active HOAs, and solar panel maintenance appointments have to work around that. Tell us the gate code or meet-the-crew requirement when you book and we will plan for it; if your HOA rules require proof that the crew is insured before anyone sets a ladder, we send our certificate same day. One honest note: California does not license cleaning companies, so a "licensed" claim from any panel washer means little. Insurance is the thing to verify. Dogs in the yard? Just flag pets at booking so the crew knows.
On the roof itself: one-story roof or two-story roof makes no difference to the result, only to the setup. Fall protection and ladder safety are standard on every job, and steep roof pitch or odd tilt angle arrays with access issues simply move a job into the +20% tier, quoted before we ever arrive. Our scheduling window holds either way: most jobs within 3 days.
Where we work
Serving all of Roseville, and over the county line
We clean residential solar panel cleaning jobs across the whole city: WestPark, Fiddyment Farm, Highland Reserve, the neighborhoods around the Galleria area, and out past the Grounds toward older east Roseville. We also cover Granite Bay and the rest of Placer County; this is the Roseville arm of our main solar panel cleaning page, with a Rocklin page next door. And yes, Citrus Heights too, even though it sits across the county line. Wesley grew up in Citrus Heights, so that one is personal.
