[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels, controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] Photovoltaic panels need to be placed in open areas for a long time, which causes dust in the air to adhere to the surface of the photovoltaic panels. If it rains, although the attached dust can be washed away, when the rain stops, the attached rainwater will absorb the dust in the air. When the rainwater is evaporated by the sun, the dust will stick to the surface of the photovoltaic panels and is difficult to remove. At present, the surface of photovoltaic panels needs to be cleaned manually, resulting in low efficiency. Therefore, we urgently need a cleaning system for photovoltaic panels to solve the above problems. Utility Model Content
