Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel coating, and more specifically, to a coating device for photovoltaic component coating liquid. Background Art

[0002] Photovoltaic modules are generally installed outdoors. After long-term use, dust, sand or other foreign matter will adhere to the surface of the photovoltaic modules, which will block the incidence of light and affect the photoelectric conversion efficiency. Especially in some places with harsh operating environments, such as areas where sandstorms often occur, the operation and maintenance of photovoltaic modules in these areas is particularly important. In order to reduce the number of later operation and maintenance and reduce the difficulty of cleaning the surface of photovoltaic modules, a layer of coating liquid is usually applied to the clean surface of photovoltaic modules to reduce the adhesion of dust, sand and rust, and increase the surface hydrophobicity, so that the flow of water on the surface is greatly enhanced, and the foreign matter on the surface of the photovoltaic module is taken away when the water flows on the surface.

[0003] When a common photovoltaic module coating liquid coating device is used, the surface of the photovoltaic module is not cleaned simultaneously, so that impurities attached to the surface of the photovoltaic module are covered in the coating liquid, which not only affects the appearance of the photovoltaic module, but also the impurities will block the photovoltaic module from generating electricity for a long time, which is not conducive to the use of the photovoltaic module.
