Device for cleaning and cooling glass surface of solar component

Abstract

The invention provides a device for cleaning and cooling a glass surface of a solar component, which comprises a left frame, a right frame, an upper main shaft, a lower main shaft, a synchronous belt wheel, a synchronous belt, a brush part, a driven wheel, a driving wheel, a direct current motor, a running water pipe, an electromagnetic valve and a battery component, wherein the direct current motor drives the upper main shaft and the lower main shaft to rotate, thereby driving the brush part to move up and down along the surface of the battery component; the running water pipe is controlled by the electromagnetic valve to spray water to the surface of the battery component at definite time, and the water not only can be used for washing and eliminating dust, fallen leaves, bird droppings and other impurities on the glass surface at definite time but also can be used for lowering the working temperature of the battery component; and the power sources of the electromagnetic valve and the direct current motor are provided by the battery component. The experiment proves that if the device provided by the invention is arranged on the existing solar battery component, compared with the prior art, the annual output power of the battery component with the same specification is improved by 20%-22%, thus the economic benefit is very obvious.

Description

Technical field: [0001] The invention relates to a solar battery module, in particular to a cleaning and cooling device for the solar module during use. Background technique: [0002] The power generation process of solar cells can be summarized as follows: sunlight and other light pass through the transparent glass plate and EVA on the surface of the solar module to irradiate the solar cells. Solar cells absorb photons with a certain energy, and excite non-equilibrium carriers (photogenerated carriers)-electron-hole pairs. These electrons and holes should have sufficient lifetimes not to recombine and disappear until they are separated. Under the action of the built-in electric field of the P-N junction of the solar cell, these photo-generated carriers with opposite signs will separate the electron-hole pairs, the electrons will be concentrated on one side, and the holes will be concentrated on the other side, resulting in the accumulation of opposite charges on both sides...

AI Technical Summary

Problems solved by technology

[0005] At present, people pay great attention to improving the power output of solar cell modules in the design and manufacturing process, but few people study how to maximize the output power of solar cell modules in the long-term use process, and there is no corresponding technical solution support
