光伏（PV）组件 型式核准、设计和安全鉴定 重新测试

[中文适用范围]： 本文件规定了维护经过或将要进行修改的陆地光伏组件的型式批准、设计和安全认证的统一方法。本文件涉及两种类型的光伏组件技术：基于晶片的技术（WBT）和单片集成（MLI）薄膜技术。材料选择、组件和制造工艺的变化可能会影响修改产品的电气性能、可靠性和安全性。本文件列出了典型修改以及基于不同测试标准的重新测试要求。它提供了一定程度的帮助；在某些情况下，可能需要工程判断。所选的测试序列用于识别修改产品的不利变化。成功遵循本文定义的测试序列的产品被认为符合其最初进行完全认证的标准。重新测试程序中包含的样品数量以及通过/失败标准列在参考标准IEC 61215和IEC 61730中。此外，如适用，可以使用IEC 61215和IEC 61730中描述的代表性样品。 [外文原描述]： 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 The contents of the corrigendum 1 of July 2024 have been included in this copy.
