IEC TS 62915:2023规定了一种统一的方法，用于维护已经或将对其原始评估设计进行修改的地面光伏组件的型式认证、设计和安全资格。本文件涉及两种类型的光伏组件技术，基于晶圆的技术（WBT）和基于单片集成（MLI）薄膜的技术。 本文档列出了基于不同测试标准的典型修改和由此产生的重新测试要求。它提供援助；在某种程度上，可能需要工程判断。 本出版物包含xls文档形式的附件。这些文件旨在作为补充，并不构成出版物的组成部分。 这第二版取消并取代了2018年出版的第一版。与上一版相比，此版本包括以下重大技术变更: -本版本中删除了先前对光伏组件特定工艺相关变更的引用，代之以一般要求，以确保按照IEC 62941建立一致的质量管理体系 -IEC 61215和IEC 61730的参考资料已更新至最新版本（分别为2021年和2023年） -关于新增加的测试（如循环（动态）机械载荷（MQT 20）和电位诱导退化（MQT 21））的重新测试要求在本版中讨论 -为清楚起见，已将IEC 61215和IEC 61730的复检要求分开 -本版提供了一个综合矩阵表，总结了每种可能的材料变更或设计修改的所有复检要求 -参考组件级标准，即IEC 62788-1系列和IEC 62788-2系列，包括在本版本中，以解决可能对进入新光伏组件结构的关键子组件进行的更改 -晶体硅和薄膜参考文献已更新，以与更新的IEC 61215和IEC 61730标准中的命名法一致；即基于晶圆的技术(WBT)和单片集成(MLI)薄膜光伏组件 -在本版本中，通过删除与4.2中的子条款相同的冗余部分，对4.3进行了截断和简化，解决了MLI薄膜光伏组件的重新测试要求 根据IEC TS 63126“高温运行光伏组件、组件和材料鉴定指南”重新测试组件的指南已添加到本版中。 -在此版本中，增加了对影响系统与同一型号变体兼容性的变更的要求

IEC TS 62915:2023 sets forth a uniform approach to maintain type approval, design and safety qualification of terrestrial PV modules that have undergone or will undergo modification from their originally assessed design. This document addresses two types of PV module technologies, wafer-based technologies (WBT) and monolithically-integrated (MLI) thin-film based technologies.
This document lists typical modifications and the resulting requirements for retesting based on the different test standards. It provides assistance; at some level, engineering judgement may be needed.
This publication contains attached files in the form of xls document. These files are intended to be used as a complement and do not form an integral part of the publication.
This second edition cancels and replaces the first edition published in 2018. This edition includes the following significant technical changes with respect to the previous edition:
- Prior references to specific process-related changes to PV modules have been removed in this edition and replaced with a general requirement to ensure that a consistent quality management system is in place per IEC 62941
- References to IEC 61215 and IEC 61730 have been updated to the latest editions (2021 and 2023 respectively)
- Retest requirements with respect to new added tests such as cyclic (dynamic) mechanical load (MQT 20) and potential-induced degradation (MQT 21) are addressed in this edition
- Retest requirements for IEC 61215 and IEC 61730 have been separated for the sake of clarity
- A comprehensive matrix table summarizing all the retest requirements for each possible change in material(s) or design modification is provided in this edition
- References to component level standards, namely IEC 62788-1 series and IEC 62788-2 series, are included in this edition to address changes that could be made to the critical sub-components going into new PV module constructions
- Crystalline silicon and thin film references have been updated to be consistent with nomenclature in the updated IEC 61215 and IEC 61730 standards; namely, wafer-based technology (WBT) and monolithically integrated (MLI) thin film PV modules
- In this edition, 4.3 which addresses retest requirements for MLI thin film PV modules has been truncated and simplified by removing redundant sections that are identical with the subclauses in 4.2
Guidance for retesting modules according to IEC TS 63126, “Guidelines for qualifying PV modules, components and materials for operation at high temperatures” has been added to this edition.
- In this edition, requirements have been added for changes affecting system compatibility with variants of the same model
