摘要
通过选用不同粒径的沙漠沙尘颗粒沉积于太阳能光伏组件表面,对太阳能光伏组件的背板温度变化及输出特性进行实验研究。结果表明:随着沉积在光伏组件表面的沙尘粒径(0.05～0.3 mm)变化,组件的开路电压变化较小,其最大差值为0.25 V,变化幅度约1.2%;对短路电流和输出功率有较大影响,短路电流的最大差值大约为13%,输出功率的最大差值约为17%。
Surface of PV modules in desert areas have sand can cause changes in the temperature of components,which seriously affects their output efficiency. In this paper,Studying the backplane temperature changes of modules and the output characteristics of PV modules by choosing different particle size of dust. The results show that different dust particlesizes(0.05-0.30 mm)havelittleeffectontheopencircuitvoltageofthemodule,themaximumdifferenceis 0.25 V,the variation range is about 1.2%;but the short circuit current and output power have a great influence. The maximum difference of short circuit current is about 13% and the maximum difference of output power is about 17%.
