Solar cell panel dedusting comb-shaped circuit and working system thereof

Abstract

Provided is a solar cell panel dedusting system which is composed of a solar cell panel dedusting comb-shaped circuit, a solar energy storage battery and a control system. The comb-shaped circuit is composed of a substrate, a circuit layer and a superficial layer. The substrate is formed by a glass material. The interface layer is composed of pins of positive and negative electrodes, an array parallel main electrode and parallel period alternatively distributed comb-shaped sub-electrodes. The surface of the circuit layer is covered with a transparent insulating protection film. The control system comprises an inverter, a relay, a transformer and a microcontroller. The microcontroller monitors the solar cell panel output voltage signal in real time. When the surface of the solar cell panelis covered with dust and the light transmittance is reduced, leading to the output voltage is lower than a preset critical value, a one-chip microcomputer emits an instruction to close the relay. Then the solar cell panel dedusting comb-shaped circuit is conducted. The charge particles jump up and fly to the edge under the effect of a traveling wave electric field force and the effect of dedusting is achieved. When the output voltage signal is higher than the preset critical value, the one-chip microcomputer emits an instruction to open the relay so that the dedusting loop is cut off.

Description

technical field [0001] The invention relates to a solar cell panel dust removal system, in particular to a solar cell panel dust removal comb circuit and a working system, belonging to the field of solar power generation. Background technique [0002] At present, the dust removal method used to solve the problem that the dust coverage on the surface of the solar panel affects the power generation efficiency is mentioned in Cao Hongxing's paper "Summary of Moondust Protection Methods for Optical Systems"; but the dust removal method mentioned in the paper has the following Disadvantages: Due to the electrostatic effect, the dust has a great adsorption force, and it is difficult to clean the dust with brush cleaning and air jet method; and there will be residues (liquid, colloid) after cleaning with liquid flushing and adhesion methods; at the same time, these methods are It takes a lot of human and material resources. Contents of the invention [0003] In order to overcome...
