Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation panels, in particular to a cleaning device for photovoltaic power generation panels. Background Art

[0002] The core component of photovoltaic panels is solar cells, which are usually made of silicon and consist of two different layers, one of which stores extra electrons and the other empty layer can absorb electrons. When photons from the sun shine on the solar panel, an electric potential difference will be formed on the contact surface. By leading out this potential difference through wires, an electric current can be formed. Since photovoltaic panels are usually set up outdoors, after a period of use, more dust and other pollutants are likely to accumulate on their surface. The accumulation of dust significantly reduces the luminous flux of the photovoltaic panel, thereby reducing the photovoltaic panel's power output capacity.

[0003] In the prior art, a cleaning device is installed on the photovoltaic panel to clean its surface, but the existing cleaning device cannot protect the surface of the photovoltaic panel in rainy, snowy or hail weather. In rainy and snowy weather, a large amount of snow accumulates on the photovoltaic panel or it is covered by ice, which makes it difficult for the existing cleaning device to clean it. Strong sweeping and brushing may cause irreversible damage to the surface of the photovoltaic panel. Summary of the invention
