Currently, photovoltaic panels are not only used in megawatt-class photovoltaic power stations, but are also increasingly used in the home field. Photovoltaic panels are installed on the roof through brackets, and the power generation of photovoltaic panels meets part of the power supply of the home. When photovoltaic panels are placed outside for a long time, they are easily covered by dust in the external environment, resulting in a decrease in power generation. Therefore, photovoltaic panels need to be cleaned regularly.
