Professional solar panel cleaning costs about $150–$450 per visit in the U.S. for a typical 15–25-panel home, or roughly $10–$25 per panel. National averages from major price surveys range from about $258 (Thumbtack) to $465 (LawnStarter). Expect a minimum call-out fee of around $100–$150, and higher prices for steep, two-storey or hard-to-reach roofs. In the UK, the average is about £145 per visit (≈£9 per panel).
Key takeaways
- Price is driven by panel count, roof height/pitch, how dirty the panels are and where you live.
- Bundling cleaning with an inspection, or booking an annual plan, usually lowers the per-visit price.
- Cleaning pays for itself when the energy you recover is worth more than the visit — most likely in dusty, pollen-heavy or high-electricity-price areas.
- DIY costs $30–$250 for tools but carries roof-safety and warranty risks.

Average solar panel cleaning cost in 2026
Price surveys from large home-service marketplaces give a consistent picture:
| Source | Typical range | Average / per panel |
|---|---|---|
| Thumbtack (national data)[1] | $172–$385 per visit | ≈ $258 average |
| LawnStarter (20–25 panel systems)[2] | $300–$635 per visit | $465 average; $13–$25 per panel |
| Bob Vila[3] | $150–$630 per visit | $15–$25 per panel; labor $100–$150/hr |
| HomeServe[4] | — | $10–$25 per panel; ~$100 minimum |
Solar panel cleaning cost per panel and by system size
Many cleaners quote per panel with a minimum charge, so cost per panel falls as systems get larger. The estimates below use $10–$20 per panel with a $120 minimum for an easy, single-storey roof:
| Number of panels | Approx. system size | Estimated cost per visit |
|---|---|---|
| 10 | ~4 kW | $120–$200 |
| 15 | ~6 kW | $150–$300 |
| 20 | ~8 kW | $200–$400 |
| 25 | ~10 kW | $250–$500 |
| 30+ | ~12 kW+ | $300–$600 (volume discounts common) |

What affects solar panel cleaning prices?
- Number and size of panels — more glass takes more time, but per-panel rates usually drop on larger arrays.
- Roof height, pitch and material — two-storey, steep, tile and metal roofs need extra safety equipment and time; expect 20–50% more.
- Level of soiling — baked-on bird droppings, lichen or a first clean after years can cost more than routine maintenance cleans.
- Method — purified-water, water-fed-pole systems cost more to run than a hose, but are safer for coatings and warranties.
- Location — labor rates, travel fees (often beyond ~20 miles), water restrictions and local demand. Dusty Southwest states have more providers and sometimes lower prices; see our state guides.
- Add-ons — inspection reports, bird-proofing mesh, gutter cleaning or recurring service plans.
How much does DIY solar panel cleaning cost?
| Item | Typical price |
|---|---|
| Soft solar brush + telescopic pole | $40–$150 |
| Inline deionizing / RO water filter | $50–$250 (plus refill resin) |
| All-in-one solar panel cleaning kit | $60–$200 |
| pH-neutral panel cleaner (optional) | $15–$30 |
| Fall-protection harness and anchor (if roof access needed) | $100–$300 |
After the first purchase, DIY cleans cost almost nothing — but only DIY if you can work safely from the ground or a low, single-storey roof. Follow our step-by-step solar panel cleaning guide to avoid the mistakes that damage panels. Robotic or automatic cleaning systems exist, but at $2,000+ they rarely pay back on a home system.[2]
Is professional solar panel cleaning worth it?
It depends on how much energy dirt is costing you. NREL research puts soiling losses at up to about 7% a year in dustier parts of the U.S., with roughly 5% a common modeling assumption.[5] For an 8 kW system producing ~11,200 kWh a year at $0.17/kWh, a 5% loss is worth about $95 a year — less than one professional visit. At $0.30/kWh in California or with 10% losses in a dusty area, the same system loses $170–$340 a year, and an annual clean clearly pays for itself.
Rule of thumb: pay for professional cleaning when the energy you’d recover in a year is worth more than the visit, when your roof is unsafe for DIY, or when your warranty or installer requires documented cleaning. Otherwise clean less often or DIY from the ground.
Solar panel cleaning cost in the UK
Analysis of more than 725 UK quotes puts the average professional clean at about £145 per visit, around £9 per panel, with small systems of up to 10 panels from about £70 and typical family homes (11–14 panels) around £115.[6] Access is the biggest price factor, just as in the U.S.

7 ways to save on solar panel cleaning
- Clean based on monitoring data, not the calendar.
- Time your clean after pollen season or the dusty season, not before.
- Ask for a per-panel price and a written quote that states the method (purified water, soft brush).
- Bundle cleaning with an inspection or gutter/window cleaning.
- Sign an annual plan (two visits) for a lower per-visit rate.
- Get at least three quotes and check insurance.
- DIY ground-level panels and pay a pro only for the hard-to-reach ones.
Frequently asked questions
How much does it cost to clean solar panels?
Most U.S. homeowners pay $150–$450 per visit, or about $10–$25 per panel, with a minimum charge of around $100–$150. Steep or two-storey roofs cost more.
How much should I charge to clean solar panels?
Cleaners commonly charge $5–$25 per panel depending on access and local rates, with a minimum call-out fee. Larger arrays get lower per-panel pricing.
How often should I pay for solar panel cleaning?
Once or twice a year for most homes; every 3–4 months in very dusty, agricultural or desert areas.
Is solar panel cleaning covered by insurance or warranty?
No. Cleaning is routine maintenance paid by the owner. However, following the manufacturer’s cleaning method helps protect your warranty.
Is it cheaper to clean solar panels yourself?
Yes — after $30–$250 in tools, DIY cleaning is almost free. But roof falls are a serious risk, so DIY only from the ground or a low, safe roof.
