在不考虑周围环境阴影影响的情况下，很难精确估算光伏阵列上的总辐照度，尤其是对于城市地区的光伏建筑一体化（BIPV）系统。准确评估阵列上的实际辐照有助于验证光伏系统的性能。在本研究中，作者提出了一种计算阴影因子的方法，通过应用摄影测量方法，使用鱼眼照片捕捉整个环境。遮阳因子定义为光伏阵列上的实际辐照与无遮阳组件时的理想辐照的比值。利用遮蔽因子可以方便地计算出某一阵列的实际辐照度。
It is difficult to estimate precisely total irradiance on photovoltaic (PV) arrays without consideration of the effect of shadow by surroundings, especially for building integrated photovoltaic (BIPV) systems in an urban area. The accurate evaluation of actual irradiation on the arrays may contribute to the verification of the performance of PV systems. In this research, the authors propose the method of calculating the shading factor by applying the photo survey method using fisheye photographs to capture whole surroundings. The shading factor is defined as the ratio of actual irradiation on PV arrays to ideal irradiation with no shading modules. Actual irradiation on a certain array can be calculated easily by using the shading factor.
