积灰对光伏组件最佳安装倾角的影响
Influence of ash accumulation on optimum installation angle of PV modules
摘要
Abstract
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.关键词
