前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件是GB/T45021《光伏组件性能测试和能量评定》的第1部分。GB/T45021已经发布了以

下部分：

——第1部分：辐照度和温度性能测量和功率评定。

本文件修改采用IEC61853⁃1：2011《光伏组件性能测试和能量评定第1部分：辐照度和温度性

能测量和功率评定》。

本文件增加了“术语和定义”一章。

本文件与IEC61853⁃1：2011的技术差异及其原因如下：

——修改了范围（见第1章），以便于更好的反映标准的适用性；

——更改了抽样方法，用GB/T2828（所有部分）代替了IEC60410（见第4章），IEC60410已

废止；

——用规范性引用的IEC60891:2021代替了IEC60891:2008（见9.1和10.1.5），IEC60891已修

订更新版本；

——用规范性引用的IEC60904⁃7:2019代替了IEC60904⁃7（见9.3.6和9.5.6），IEC60904⁃7已修

订更新版本；

——删除IEC61215:2005和IEC61646:2008，对应增加引用了IEC61215-2:2021（见第6章、8.1

和9.5.8），IEC61215:2005和IEC61646:2008已修订合并到IEC61215系列。

本文件做了下列编辑性改动：

——将第1章中资料性引用的IEC61853⁃3增加到参考文献；

——将文本中规范性引用的ISO/IEC17025增加到第2章。

请注意本文件的某些内容可能涉及专利。本文件的发布机构不承担识别专利的责任。

GB/T45021.1—2024

引言

光伏（PV）组件通常在电池温度25℃、辐照度1000W/m2和光谱AM1.5的标准测试条件（STC）

下进行。然而，现场的光伏组件在一系列温度、辐照度和光谱范围内运行，为了准确预测组件在不同条

件下的产能，有必要对宽范围的温度、辐照度、入射角和光谱下对组件进行评估。

GB/T45021《光伏组件性能测试和能量评价》拟由四个部分组成。

——第1部分：辐照度和温度性能测量与功率等级评定。目的在于规定在一系列辐照度和温度

下，根据额定功率（瓦）评估光伏组件性能的要求。

——第2部分：光谱响应度、入射角和组件工作温度测量。目的在于确立测量入射角和光谱响应

度的影响以及根据辐照度、环境温度和风速评估组件温度的测试程序。

——第3部分：光伏组件的额定能量。目的在于描述光伏组件额定能量（瓦时）的计算方法。

——第4部分：标准参考气候文件。目的在于给出可用于能量额定值计算的标准时间段和天气

条件。
