In order to increase the amount of power generated, photovoltaic panels usually connect multiple photovoltaic panel units end to end, thereby increasing the lighting area and thus increasing the amount of power generated.

[0003] It is usually dusty outdoors in the north, and dust can easily accumulate on photovoltaic panels. Over time, the dust will become thicker and thicker, and the accumulation area will become larger and larger, which will affect the lighting area of ​​the photovoltaic panels, thereby reducing the working efficiency of the photovoltaic panels and reducing the energy conversion rate of the photovoltaic panels.

[0004] When cleaning, the current photovoltaic operation and maintenance robot cannot keep the electric cleaning roller always perpendicular to the surface of the solar panel. After long-term use, the electric cleaning roller cannot be in close contact with the surface of the solar panel, which affects the cleaning effect of the solar panel surface. At the same time, the distance between the electric cleaning rollers cannot be adjusted for solar panels of different widths, resulting in the electric cleaning roller needing to be cleaned multiple times during cleaning, which affects the cleaning efficiency. When the device is working, it will slip, resulting in instability during cleaning. The device may also slide off the surface of the solar panel, causing damage to the device.
