[0002] Solar cell panel array is usually used in outdoor environment, and the atmosphere is full of dust particles with different shapes, so dust is easily deposited on the surface of solar cell panel. The dust falling on the surface of photovoltaic module will block sunlight and reduce the transmittance of the surface glass of photovoltaic module, resulting in a decrease in the amount of solar radiation reaching the cell surface. Dust has become one of the main problems affecting the performance ratio of photovoltaic power station. Therefore, it is necessary to clean the solar cell panel regularly. The traditional cleaning method is to use a long-handled cleaning tool manually. However, since the photovoltaic array is composed of multiple solar cell panels arranged side by side, this cleaning method is time-consuming and labor-intensive, and the cleaning effect is limited.

The cleaning device maintains the same inclination angle as the solar cell panel and moves along the surface of the solar cell panel in this state to automatically clean the solar cell panel. The cleaning device is powered by a solar cell. During movement, the first cleaning unit collects dust to the middle of the frame, and the second cleaning unit collects dust to the dust collection tank. The inclination angle of the cleaning device can effectively discharge dust from the dust collection tank, ensuring complete and low-risk cleaning. The third cleaning unit uses the electrical energy in the power storage module to clean the solar cell of the cleaning device, effectively ensuring the normal operation of the cleaning device.
