为解决光伏组件表面积尘引起的发电效率降低问题,提出一种基于静电吸附机理的光伏组件无水化除尘方法。在给出除尘机理、灰尘颗粒荷电参数并进行除尘装置结构设计的基础上,采用COMSOL Multiphysics软件分析除尘区域的电场、电势分布及不同粒径的灰尘颗粒在除尘区域中的运动情况,并搭建光伏组件静电吸附式除尘实验平台进行实验。结果表明,大粒径的灰尘颗粒更易被清除,静电除尘率最高可达99.56%,除尘后光伏组件发电效率可达表面无尘状态的97.73%,所提方法能够实现光伏组件表面有效且高效的除尘。
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.
