Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly to a device for uniformly cleaning photovoltaic panels. Background Art

[0002] Photovoltaic panels generally need to be installed outdoors. In order to increase power generation, multiple rows of photovoltaic panels are usually installed in parallel to increase the lighting area and thus increase power generation. Since most photovoltaic panels are installed outdoors, dust is likely to accumulate on the photovoltaic panels. In the northwest region of China, due to the significant monsoon climate, over time, the dust will accumulate thicker and the accumulation area will become larger, which will affect the lighting area of the photovoltaic panels and the lighting of the photovoltaic panels.

[0003] After retrieval, in the prior art, a water spraying and cleaning mechanism that walks on the surface of the photovoltaic panel is mostly adopted. When the device passes by, the dust on the surface will be washed away. This method not only wastes a large amount of water resources, but also when birds excrete in the air, some excrement often directly falls on the photovoltaic components. After being exposed to the sun, there are often traces left at the bonding place between the excrement and the photovoltaic components, which are not easy to clean. To further improve the cleaning efficiency, we propose a new type of cleaning device. Summary of the Invention
