Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic power generation panel cleaning devices, in particular to a self-cleaning device for photovoltaic power generation panels. Background Art
[0002] Photovoltaic panels refer to devices that use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. They use the photovoltaic effect. When light shines on photovoltaic panels, photons will excite electrons in the photovoltaic materials, causing them to jump to the conductive band, thereby generating current. This current can be used to supply power or stored for later use. At present, the semiconductor materials used for power generation mainly include monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. Since photovoltaic panels need to be exposed to sunlight to generate electricity, most of them are installed outdoors. However, during outdoor use, when the outside temperature is low, condensation is prone to occur on the surface of photovoltaic panels, thereby forming an ice layer. The ice layer will block the sunlight, resulting in the photovoltaic panels being unable to fully absorb light energy, reducing the power generation efficiency and production capacity of the photovoltaic panels. In addition, the ice layer will make the surface of the photovoltaic panels more fragile, increasing the risk of damage. Utility Model Content
