IEC 61853-2:2016定义了测量辐照度入射角对设备输出功率影响的测量程序，确定了给定环境和安装条件下模块的工作温度，并测量了模块的光谱响应度。第二个目的是提供一组特征参数，用于详细的能源预测。所述测量值需要作为IEC 61853-3中所述模块能量额定程序的输入。

IEC 61853-2:2016 defines measurement procedures for measuring the effects of angle of incidence of the irradiance on the output power of the device, determines the operating temperature of a module for a given set of ambient and mounting conditions and measure spectral responsivity of the module. A second purpose is to provide a characteristic set of parameters which will be useful for detailed energy predictions. The described measurements are required as inputs into the module energy rating procedure described in IEC 61853-3.
