Professional solar panel cleaning costs about $200 on average for a typical residential array.1,2 Per-panel rates run $3 to $20 depending on the source, and many companies charge a minimum fee. Prices below are national figures from each source’s latest published data.*
*National figures, not local quotes; sources were last updated between 2025 and October 2026. Your price depends on panel count, roof access, and whether the company charges per panel, per hour, or a flat rate.

What sources say
| Source | Figure | Scope |
|---|---|---|
| Yelp | $200 average; $95 – $350 range | Flat rate, all panels on a 1,600 – 2,000 sq ft house; updated October 2026 |
| Thumbtack | $12 – $20 per panel; about $200 per cleaning | Residential arrays of 15 – 35 panels; 2025 data, last updated Oct 20 |
| SolarReviews | $5 – $15 per panel ($100 – $300 for 20 panels) | Industry estimate; page updated about a year before access |
| Homewyse | $129 – $163 per panel | Unit-cost estimate including setup and a 2-hr minimum labor charge (January 2026) |
The per-panel rates disagree across sources and none explains why, so read them as a spread: $3 to $20 per panel covers the lows and highs published by Yelp, Thumbtack, and SolarReviews. Homewyse’s per-panel estimate is far higher; it explicitly includes labor setup, mobilization, and transportation, with a 2-hour minimum labor charge, but the sources do not establish the reason for the full price gap.1,2,3,4
Flat rates, hourly rates, and minimum charges
Many companies quote flat or hourly pricing instead of per-panel rates:1,2
| Pricing model | Typical cost (source) |
|---|---|
| Flat rate, up to 32 flat panels | $130 – $150 (Thumbtack) |
| Hourly rate | $100 – $150 per hour (Thumbtack) |
| Minimum charge | $75 or more (Yelp) |
Per-panel rates also depend on access: Thumbtack notes tilted rooftop panels cost more than ground-level flat panels because of the extra safety measures required, and recommends a professional for hard-to-reach arrays.2
Is cleaning worth it?
SolarReviews estimates that dirty panels cut solar savings by $79 per year on average and nearly $2,000 over a system’s lifetime, which puts a $100 to $300 cleaning in context.3 Thumbtack adds that warranties typically do not cover cleaning, though an annual inspection (about $150) is often the only other routine service a system needs.2
DIY cleaning
SolarReviews puts DIY cleaning materials at around $100, with a ladder as the biggest expense if you do not own one.3 Thumbtack notes DIY is feasible but recommends hiring a pro when panels are numerous or on a tilted roof.2
