双面光伏组件辐照度模型的建构与研究

文章构造了双面光伏组件的辐照度计算模型,用于评估双面光伏组件的总可接收太阳辐射能量,其中组件的正面辐照度基于Perez散射模型计算,组件的背面辐照度基于使用配置因子和入射角校正因子的模型计算。文章研究了双面光伏组件及阵列的配置参数(组件的倾斜角度)对光伏组件及阵列的可接收总太阳辐射能量的影响。研究结果表明,一定条件下光伏组件及阵列的配置参数的某些最优值可以使光伏组件及阵列获得最大的总太阳辐射能量。

In this paper, the irradiance calculation model of double-sided PV module is constructed, which is used to evaluatethe total solar radiation energy received by double-sided PV module. The frontal irradiance of the module is calculated based on thePerez scattering model. The backside irradiance of the assembly is calculated based ona model usinga configuration factor and anincident angle correction factor. In this paper, the influence of configuration parameters of double-sided photovoltaic modules and arrays （the tilt angle of the modules） on the total solar radiation energy received by photovoltaic modules and arrays is studied. The results show that under certain conditions some optimal values of the configuration parameters of photovoltaic modules and arrays canmake photovoltaic modules and arrays obtain the maximum total solar radiation energy.
