摘要
文章以呼和浩特地区安装倾角为0~90°且变化步长为10°的10块光伏组件为研究对象。分析了光伏面板的积灰量、倾斜面太阳总辐照度、玻璃盖板的透射率以及光伏组件的实际输出功率随安装倾角的变化规律,并提出利用积灰影响度来表征积灰对最佳安装倾角的影响程度。研究结果表明:光伏面板积灰量和光伏组件玻璃盖板透射率随安装倾角的增大而降低;理论、实际最佳安装倾角分别为30,50°;当安装倾角分别为20,50°时,光伏组件的积灰影响度分别为0.975,0.017,即积灰影响度的最大、最小值,积灰影响度能够准确反映积灰对最佳安装倾角的影响程度。
This paper takes the installation angles in the range of 0-90 ° and changing steps of 10 °of 10 PV modules for the study, analyses the ash accumulation of PV panels, the transmittance, the theoretical radiation quantity and the change law of the actual output power with the inclination.The influence degree of the ash accumulation, has been proposed to characterize the influence degree of the optimum installation angles for the ash accumulation. The results show that the ash accumulation of PV modules and the transmittance decrease with the increase of the installation angles. The theoretical installation angle is 30 ° and the actual installation angle is 50 °. The influence degree of ash accumulation at 50 ° is 0.017 and ash accumulation at 20 ° is 0.975, which are the minimum and maximum value. The influence degree of ash accumulation can accurately reflect the degree of influence of ash accumulation on the optimum installation angle.
