During the use of solar photovoltaic panels, there will be more dust or other attachments on the surface, which will affect the light transmission of photovoltaic panels and hinder the photoelectric effect, thereby reducing power generation efficiency. In addition, the temperature in summer is high, and the surface of photovoltaic panels is dusty, which is not easy to dissipate heat , the surface temperature is easily higher than 40°C, which not only reduces the power generation efficiency, but also shortens the life of the solar photovoltaic panel. Therefore, it is very important to keep the solar photovoltaic panels clean. At present, the cleaning of solar photovoltaic panels is generally carried out manually with hand-held cleaning tools. For installation on building roofs or other places that are not easy to operate, manual labor is not only labor-intensive, but also low-efficiency and dangerous. Cleaning also has the defects of uneven cleaning, poor overall effect, and easy damage to solar photovoltaic panels.
