Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic component-level dust-proof cleaning device. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules. Since the output voltage of a single solar cell is low, and the electrodes of unpackaged cells are easily detached due to environmental influences, a certain number of single cells must be sealed into solar cell modules in series and parallel to avoid corrosion of the cell electrodes and interconnects. In addition, packaging also prevents the cells from breaking. When different photovoltaic modules are used, dust is easy to adhere to the surface for a long time. When there is too much dust, it is easy to affect the power generation efficiency and needs to be cleaned regularly.

[0003] At present, when cleaning photovoltaic modules, most of them are done by spraying water and then using a mop to remove the floating dust on the surface. The operation is convenient and the cost is low, but the effect of removing bird droppings attached to photovoltaic modules is poor. Secondly, when some granular dust comes into contact with the mop, it is easy to cause wear on the surface of the photovoltaic module, affecting the use of the photovoltaic module.
