Abstract

The invention discloses a solar photovoltaic panel with a self-cleaning function. The surface of the photovoltaic panel is coated with a layer of a self-cleaning coating, and through the performance of the self-cleaning coating, the self-cleaning effect of the solar photovoltaic panel is achieved. The self-cleaning coating is prepared through the specific steps of adding a certain amount of butyltitanate into an ethyl alcohol solution, then adding hydrochloric acid into the ethyl alcohol solution to adjust the PH to be 3, adding distilled water into the mixture after a stirring reaction is conducted for 8-10 minutes, and then conducting stirring and mixing for 2-3 minutes to obtain a colloidal solution; adding a fluorosiloxane resin gel solution and a film-forming auxiliary agent into thecolloidal solution, and conducting stirring and mixing for 3-5 minutes to obtain the coating. According to the solar photovoltaic panel, the surface of the photovoltaic panel is coated with the self-cleaning coating, the self-cleaning coating is prepared by compounding resin containing a large quantity of siloxane bonds and fluorine element and titania gel, has high hydrophobicity and fouling resistance, and can achieve the self-cleaning effect.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic panels and relates to a solar photovoltaic panel with a self-cleaning function. Background technique [0002] Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. Independently operating photovoltaic power generation systems require batteries as energy storage devices. They are mainly used in remote areas without grids and areas with scattered populations. The cost of the entire system is high; Save the storage battery, not only can greatly reduce the cost, but also has higher power generation efficiency and better environmental protection performance. Solar photovoltaic power generation is usually a technology that directly converts light energy into ele...
