In the present study, a detailed investigation on air dust particles effect on photovoltaic (PV) model performance has been carried out. The scanning electron microscope analysis of the collected dust samples was being carried out, and the obtained images were being analyzed in order to observe the character and topography of the dust sample particles. The data for dust samples of different weights with change in power loss in a PV module at three solar irradiations levels of 650, 750 and 850 W/m2 have been collected. In present study, the effect of environmental dust particles on power loss in PV module has been evaluated by measuring the electrical performance index such as voltage, current and power. The minimum power value of 3.88 W has been observed during the accumulation of rice husk on PV module.

粉尘对太阳能光伏组件功率损耗影响的实验研究

在本研究中，已经对空气尘埃颗粒对光伏（PV）模型性能的影响进行了详细研究。对收集的粉尘样品进行扫描电子显微镜分析，并对获得的图像进行分析，以观察粉尘样品颗粒的特征和形貌。收集了在650、750和850 W / m2的三个太阳辐射水平下，PV组件中功率损耗变化的不同重量粉尘样品的数据。在本研究中，已通过测量电性能指标（例如电压，电流和功率）来评估环境灰尘颗粒对PV模块中功率损耗的影响。在PV组件上积累稻壳的过程中，观察到最小功率值为3.88W。
