Solar Panel Cleaning Cost (Per Panel & Per Visit)

Published ranges

These cover professional solar cleaning in general, not drone crews specifically. The two Angi pages give different ranges, which is a reminder that local quotes vary.

• Angi's 2026 solar maintenance guide: professional cleaning $200 to $500 per visit.
• Angi's 2026 solar repair guide: cleaning $15 to $35 per panel, or $150 to $350 for the whole system.

What drives the price

• Panel count and system size.
• Roof height, pitch, and how the crew reaches the array.
• Panel tilt and how dirty the panels are (dust, pollen, bird droppings).
• Water: many crews use purified water to avoid spotting.
• Whether an inspection or critter guard work is bundled in.

How often to clean

Angi suggests cleaning at least twice a year, and more often in dusty climates such as the Arizona desert. How much dirt affects your output varies by site, so ask your installer or check your monitoring app before and after a cleaning.

Drone, pole, or hand crews

Pole crews use water-fed brushes from the ground or roof edge. Hand crews work on the roof. Drone crews spray and rinse from a tethered drone, which can avoid walking near the modules on tall or steep roofs. Each can do good work; ask how they avoid scratching coatings.

Before any cleaning, check your panel manufacturer's cleaning instructions and warranty terms, and share them with the crew.

Drone cleaning operators need FAA authorization; chemical spraying may fall under Part 137. Ask your operator for their certifications.
