前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規(guī)則》的規(guī)

定起草。

本文件是GB/T45021《光伏組件性能測試和能量評定》的第1部分。GB/T45021已經(jīng)發(fā)布了以

下部分：

——第1部分：輻照度和溫度性能測量和功率評定。

本文件修改采用IEC61853?1：2011《光伏組件性能測試和能量評定第1部分：輻照度和溫度性

能測量和功率評定》。

本文件增加了“術語和定義”一章。

本文件與IEC61853?1：2011的技術差異及其原因如下：

——修改了范圍（見第1章），以便于更好的反映標準的適用性；

——更改了抽樣方法，用GB/T2828（所有部分）代替了IEC60410（見第4章），IEC60410已

廢止；

——用規(guī)范性引用的IEC60891:2021代替了IEC60891:2008（見9.1和10.1.5），IEC60891已修

訂更新版本；

——用規(guī)范性引用的IEC60904?7:2019代替了IEC60904?7（見9.3.6和9.5.6），IEC60904?7已修

訂更新版本；

——刪除IEC61215:2005和IEC61646:2008，對應增加引用了IEC61215-2:2021（見第6章、8.1

和9.5.8），IEC61215:2005和IEC61646:2008已修訂合并到IEC61215系列。

本文件做了下列編輯性改動：

——將第1章中資料性引用的IEC61853?3增加到參考文獻；

——將文本中規(guī)范性引用的ISO/IEC17025增加到第2章。

請注意本文件的某些內容可能涉及專利。本文件的發(fā)布機構不承擔識別專利的責任。

本文件由中華人民共和國工業(yè)和信息化部提出。

本文件由全國太陽光伏能源系統(tǒng)標準化技術委員會（SAC/TC90）歸口。

GB/T45021.1—2024

引言

光伏（PV）組件通常在電池溫度25℃、輻照度1000W/m2和光譜AM1.5的標準測試條件（STC）

下進行。然而，現(xiàn)場的光伏組件在一系列溫度、輻照度和光譜范圍內運行，為了準確預測組件在不同條

件下的產(chǎn)能，有必要對寬范圍的溫度、輻照度、入射角和光譜下對組件進行評估。

GB/T45021《光伏組件性能測試和能量評價》擬由四個部分組成。

——第1部分：輻照度和溫度性能測量與功率等級評定。目的在于規(guī)定在一系列輻照度和溫度

下，根據(jù)額定功率（瓦）評估光伏組件性能的要求。

——第2部分：光譜響應度、入射角和組件工作溫度測量。目的在于確立測量入射角和光譜響應

度的影響以及根據(jù)輻照度、環(huán)境溫度和風速評估組件溫度的測試程序。

——第3部分：光伏組件的額定能量。目的在于描述光伏組件額定能量（瓦時）的計算方法。

——第4部分：標準參考氣候文件。目的在于給出可用于能量額定值計算的標準時間段和天氣

條件。

功率評定

1范圍

本文件確立了光伏組件的測試和評定系統(tǒng)，確保在一系列特定條件下光伏組件功率[單位為瓦

（W）]以最大功率運行；并給出了光伏組件在不同輻照度和溫度下的全套的特性參數(shù)，便于進行光伏組

件能量評定（見IEC61853?3）。

本文件適用于地面用平板組件，如晶體硅組件以及薄膜組件。本文件也適用于單面組件。
