Photovoltaic devices—Part 5:Determination of the equivalent cell temperature(ECT) of photovoltaic(PV) devices by the open-circuit voltage method


Standard in brief
Scope of Application:  
本文件描述了用于确定光伏器件(包含光伏电池、光伏组件及同类型组件构成的光伏方阵等)ECT的首选方法,这一方法旨在比较光伏器件的热特性,确定NOCT或NMOT,以及将测得的电流-电压(I-V)特性转换到其他温度下的等效值。
本文件适用于在稳定条件下开路电压(Voc)与辐照度呈对数关系的线性器件。本文件能用于所有技术,但必须验证不存在影响测量的预处理效应。
