Written by HyreSolar Research Desk Price compilation from published, dated sources
The short answer
Solar Panel Cleaning Cost depends mainly on panel count, roof access and how dirty the array is, and this page gives the per-visit range from dated, sourced quotes. Across 12 published, dated sources retrieved October 22, 2026, one professional cleaning visit for a home system typically runs $150–$350.
No 30% federal credit applies to a system a homeowner buys: Section 25D ended for expenditures after December 31, 2025 (what changed).

What moves the price of a cleaning
Most cleaners price by the visit with a minimum charge, then scale by panel count. The array size sets the labor; access sets the risk. A single-story roof with a low pitch is the cheap case.
A second story, a steep pitch, tile or a ground-to-roof reach that needs fall protection pushes the same panel count into the upper half of the range, and some sources list a separate access surcharge.
How dirty the glass is matters too. Light dust rinses off; baked-on pollen, bird droppings, agricultural dust or wildfire ash take longer and may need deionized water and soft brushes.
Pressure washers and abrasive cleaners are a poor trade: most panel manufacturers’ installation manuals warn against them, and damage from the wrong method is not a warranty claim. Ask what water and tools the crew uses.
Frequency decides the yearly cost more than the visit price. In rainy climates many homes never need a paid cleaning; in dry, dusty or coastal areas once or twice a year is common. If birds are nesting under the array, cleaning alone will not hold; price a critter guard at the same visit.

How to check a quote
- 1Get the price for your panel count
Give the exact number of panels and the roof story count; ask whether the quote is flat per visit or per panel above a minimum.
- 2Ask what they clean with
Soft brushes and purified or deionized water are the safe answer. Decline pressure washing and detergents your panel manual does not allow.
- 3Check insurance for roof work
Ask for proof of liability insurance; a fall or a cracked panel on your roof should be on their policy, not yours.
- 4Compare against your production data
Look at your monitoring app before and after. If output does not recover, the problem is not dirt.
