Abstract

To solve the problem of reduced power generation efficiency caused by dust accumulation on the surface of photovoltaic modules, a photovoltaic module anhydrous dust removal method based on electrostatic adsorption mechanism is proposed. The dust removal mechanism, charging characteristics of dust particles, and structural design of the dust removal device were first presented.COMSOL Multiphysics software was used to analyze the electric field and potential distribution in the dust removal area, as well as the movement of dust particles with different particle sizes in the dust removal area. A photovoltaic module electrostatic adsorption dust removal experimental platform was built for dust removal experiments. The results show that larger dust particles are easier to remove, and the highest electrostatic dust removal efficiency can reach 99.56%. After dust removal, the power generation efficiency of photovoltaic modules can reach 97.73% of the surface dust-free state. The proposed method can achieve effective and efficient dust removal on the surface of photovoltaic modules.
