The semiconductor materials used to generate electricity mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. As countries have been actively promoting the application of renewable energy in recent years, the photovoltaic industry has developed rapidly.

[0003] An existing automatic cleaning robot for photovoltaic panels can refer to the Chinese invention patent with the authorization announcement number CN213162159U, which discloses an automatic cleaning robot for photovoltaic panels, "including a frame, a pair of walking tracks and a cleaning component arranged on the frame, the cleaning component including a cleaning brush, a water tank, a water pump and a water spray pipe connected to the water tank in sequence, the water spray pipe is horizontally arranged at the front end of the frame, and a plurality of water spray ports are opened on the lower surface of the water spray pipe along its length direction, and the cleaning brush can be installed at the rear end of the frame in an up and down swinging manner, and the cleaning brush includes a plurality of arc-shaped sub-brushes arranged side by side in a transverse manner. In the present invention, the water spray pipe is horizontally arranged at the front end of the frame, and the cleaning brush is arranged at the rear end of the frame. After the water spray pipe sprays water at the front end of the frame, the cleaning brush arranged at the rear end of the frame will not clean the water and the photovoltaic panel that have just been sprayed, and the sprayed water has a longer soaking and softening time for the stains on the photovoltaic panel, and the stains on the photovoltaic panel are more softened and easier to be removed, thereby achieving a better cleaning effect of the photovoltaic panel".
