摘要
采取野外测试与实验室测试相结合的方法,对内蒙古库布齐沙漠环境下的光伏组件输出特性进行研究分析。结果显示:自然沙漠环境下,积尘时间和安装倾角对沙尘覆盖下的光伏组件的输出功率均有较大影响。光伏组件暴露在自然环境下10个多月不做人工清洗,其输出功率损耗率最大可达30%;与此同时,实验室的测试结果表明,随着组件表面积尘密度的增加,组件的转换效率呈对数衰减。
There are many factors that affect the efficient operation of PV modules, for PV power station built in desert areas, the problem of loss of performance of PV modules due to dust deposition phenomenon can not be ignored. This study methord combines field testing with laboratory testing, the output characteristics of PV modules in Kubuqi desert environment in Inner Mongolia are studied and analyzed.The results showed that the dust collection time and the tilt angle have a great influence on the output power of the PV modules under cover of dust in the natural desert environment. The PV modules exposed to the natural environment for ten months without manual cleaning and the output power loss rate of PV modules up to 30% ; at the same time, the Laboratory test result elucidated that the conversion efficiency of PV modules decreased logarithmically with increasing dust deposition density.
