In practice we see 3 to 7% of annual yield recovered, depending on location and soiling. Parks near motorways or farmland sit at the higher end.

Solar panel cleaning

Dust, pollen, exhaust soot and bird fouling cost a solar park yield every year. Cleaning often pays for itself within one season.

Soiling on PV panels costs 3 to 7% of yield on average in the Netherlands, and more locally for parks near motorways, farmland or industry. Drone cleaning covers thousands of panels a day without taking the park offline.

Because no brush vehicle or foot traffic between the rows is needed, there is no risk of microcracks or damaged connectors.

—Thousands of panels per day
