IEC 61853-1:2011描述了在辐照度和温度范围内根据功率（瓦特）额定值评估光伏组件性能的要求。目标是定义一个测试和评级系统，该系统在一组定义的条件下，在最大功率运行时提供光伏组件功率（瓦特）。第二个目的是在不同的辐照度和温度值下为模块提供全套表征参数。

IEC 61853-1:2011 describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures. The object is to define a testing and rating system, which provides the PV module power (watts) at maximum power operation for a set of defined conditions. A second purpose is to provide a full set of characterization parameters for the module under various values of irradiance and temperature.
