A rotating brush solar panel cleaning machine on a telescopic pole with 3.5 m of reach, mains-powered (AC/DC converter).
Runs off mains through an AC/DC converter, so there is no battery to charge or run flat. Needs a power source within cable reach of the array.
Soiled panels lose output, and the loss is worst where nothing washes the surface between cleans. Panels are cleaned with purified water and a soft rotating brush. Never use a pressure washer on an array — it drives water past the seals.
