Influence of Module Surface Ash on Photovoltaic Power Generation Performance

在光伏发电过程中,由于光伏组件表面积灰的存在,光伏组件的发电性能会受到一定影响。基于此,研究了积灰对光伏组件发电性能的影响,结合光伏组件的光学和传热学分析理论,对积灰光伏组件进行了光学和传热学理论分析。积灰光伏组件与清洁光伏组件的对比实验结果表明,光伏组件表面积灰降低了光伏组件的发电功率和发电效率,随着积灰量的增加,光伏组件的发电功率和发电效率下降越来越大。

With the consumption of natural energy and the worsening of environmental pollution,solar energy,as a renewable and clean energy,has gradually become the basic energy of mankind.Photovoltaic power generation has become the leading trend in the field of new energy,and distributed photovoltaic power generation has been widely used in China.However,in the process of photovoltaic power generation,the power generation performance of photovoltaic modules will be affected to some extent due to the presence of surface ash of photovoltaic modules.The influence of ash deposition on the power generation performance of photovoltaic modules is studied in this paper.Combining the analysis theory of optics and heat transfer of photovoltaic modules,this paper analyzes the theory of optics and heat transfer of ash-covered photovoltaic modules.The comparison experiment results of ash-covered photovoltaic modules and clean photovoltaic modules show that the surface ash of photovoltaic modules reduces the power generation power and efficiency of photovoltaic modules.With the increase of ash deposition,the power generation power and efficiency of photovoltaic modules are decreasing more and more.
