To measure the power recovery from the solar panel after dust removal, the researcher employed 150 g/m 2 dust loading with 20° inclination at 0.7 kVpp/mm and 0.2 Hz. The output power of the panel without dust was 97%. After dust application the output power decreased to 60% which was regained to 90% after the activating EDS .
Solar panels often suffer from dust accumulation, significantly reducing their output, especially in desert regions where many of the world's largest solar plants are located. Here, an autonomous dust removal system for solar panels, powered by a wind-driven rotary electret generator is proposed.
