Solar Panel Cleaning Cost: What You'll Pay
Estimate solar panel cleaning cost per panel — with the free cleaning calculator.
Dust, pollen and bird droppings cut solar output — a 10–20% loss is common in dry areas. Cleaning once or twice a year is usually enough, and it's cheaper than you think.
THE SHORT ANSWER
The short answer
Professional solar panel cleaning runs $150–$400 per visit, or about $5–$20 per panel depending on roof access and system size. Cleaning twice a year is usually enough.
What it costs
Per-panel pricing runs $5–$20. Flat-rate quotes for a typical 20-panel home land at $150–$400. Steep roofs, ground-mounted systems and dusty regions push the price up.
- Per panel: $5–$20
- Typical home (20 panels): $150–$400
- Frequency: 1–2 times per year
- Output loss without cleaning: 10–20% in dusty areas
DIY vs professional
DIY with a hose and soft brush works for low roofs and mild grime. Skip high-pressure washing — it can damage panels and void warranties. Professionals include deionized water and safe access.
