Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel cleaning technology, specifically a self-powered photovoltaic panel cleaning robot. Background Technology

[0002] Photovoltaic power plants are exposed to the outdoor environment for a long time and suffer from the erosion of natural conditions. Dust often accumulates on the surface of their photovoltaic modules, which not only reduces the light transmission efficiency but also directly reduces the amount of radiation that the modules can receive. Therefore, it is particularly important to clean the dust on the surface of photovoltaic panels regularly.

[0003] Currently, most commercially available photovoltaic (PV) panel cleaning devices use brushes as cleaning tools to wipe the surface of PV panels. However, when hard dust particles adhere to the PV panel surface, the frictional resistance between the brush and the PV panel increases significantly. This undoubtedly increases the risk of scratches or damage to the PV panel surface. In addition, after use, the brush often retains a large amount of dust inside, which greatly reduces its cleaning efficiency the next time it is used, making it difficult to meet the needs of efficient PV panel cleaning. Therefore, it is of great significance to research a new self-powered PV panel cleaning robot to solve the above problems. Utility Model Content
