Abstract

last thirty years, the PV technology is the most know while the efficiency of it around 14-18% for the polycrystalline type, furthermore the PV technology affect by the external factors as the solar irradiance, the ambient temperature, dust and humidity, some of this factors has a negative impact on the yield energy of the photovoltaic panel. The deposition of the dust on the surface of the PV module due to the sandstorms is the most problems affecting in the performance of PV module, specifically in the desert region as Ouargla city. In spite of the country have a big mean annual irradiance values but the dust is affected as large negative impact, it is worthwhile to research, the effects of dust on the performance of photovoltaic panels and impact on their electrical parameters. The main aim of this work is to research the effect of deposition of the dust on the some electrical parameters of PV panels under normal weather conditions with a dusty panel and clean one. From the experimental results the prove that the accumulation of dust a large negative impact on the short circuit current but a slight on the open circuit voltage.
瓦尔格拉地区粉尘沉积对多晶硅光伏组件影响的原位研究
近三十年来,光伏技术最为人所知,其效率在14-18%左右,为多晶型,此外,光伏技术受外界因素的影响,如太阳辐照度,环境温度,灰尘和湿度,其中一些因素对光伏板的产量有负面影响。由于沙尘暴导致的光伏组件表面粉尘沉积是影响光伏组件性能的最大问题,特别是在瓦尔格拉市这样的沙漠地区。尽管我国的年平均辐照度值都很大,但粉尘对光伏板的负面影响也很大,因此值得研究粉尘对光伏板性能的影响以及对其电气参数的影响。本研究的主要目的是研究在正常天气条件下,粉尘沉积对光伏板某些电学参数的影响。实验结果表明,粉尘的积累对短路电流有较大的负面影响,而对开路电压影响较小。
