Photovoltaic power generation, as one of the main green energy sources, is increasingly being used. In recent years, solar photovoltaic panels have been widely used, and the use of solar photovoltaic panels has greatly alleviated the pressure of electricity consumption. Since the photovoltaic panels of new energy street lamps are placed in outdoor areas, a lot of dust will accumulate on the surface of the equipment. The photovoltaic cells covered by dust will become load resistors that do not generate electricity, consuming the electricity generated by the connected batteries and causing heat. This process will aggravate the aging of the panels, reduce the photoelectric conversion rate, and in severe cases cause fires, resulting in the street lamps not being able to illuminate normally or even being damaged.
