[0002] Solar power generation equipment is often installed in outdoor environments, which are often windy and sandy. After the equipment is used for a long time, impurities such as sand and dust will gradually accumulate on the surface of the solar photovoltaic panels, affecting the solar photovoltaic panels' absorption of solar energy, and thus affecting the equipment's power generation efficiency. It is also easy to cause failures of the solar photovoltaic panels. Therefore, solar power generation equipment needs to be cleaned regularly or irregularly.

[0003] The existing cleaning components are relatively complex. For some photovoltaic panels installed in wasteland, the existing devices are very inconvenient to use and move. At the same time, when the existing devices move up and down to clean the photovoltaic panels, they will push dust and impurities to the upper and lower ends of the photovoltaic panels, making the cleaning effect less than ideal.
