[0002] Photovoltaic module components are a type of power generation device that generates direct current when exposed to sunlight. They consist of thin, solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). They have high photoelectric conversion efficiency and high reliability. Photovoltaic modules require cleaning after extended use.

[0003] The scraper of the existing photovoltaic cleaning drone is fixed. When the angles of the photovoltaic modules to be cleaned are different, it is difficult to completely clean the surface of the photovoltaic modules, and the cleaning effect is poor. At the same time, the nozzle of the existing photovoltaic cleaning drone cannot be adjusted, and the water flow from the nozzle cannot cover the surface of the photovoltaic modules, which impairs the cleaning effect. For this reason, we proposed a photovoltaic cleaning drone. Utility model content
