标准摘要
[中文适用范围]: 本文档定义了在应用或环境中部署的模块的附加测试要求,其中光伏模块可能暴露于冰雹冲击导致超出IEC 61215系列范围的高应力。当前IEC 61730系列的安全标准和IEC 61215系列的设计资格和类型批准标准规定了光伏模块承受特定冰雹冲击能力的测试。其中的要求是市场准入的最低要求,并未写入旨在通过后续机械和热机械测试来传播冰雹冲击可能导致的潜在电池损坏,这些测试模拟了模块在冰雹后可能暴露的环境应力。在本文档中,模块最初暴露于200小时的湿热以考虑一定程度的湿度和热量,然后暴露于冰雹应力,随后是IEC 61215-1.2021图2中序列C的选定热机械应力测试。然后将这些模块的功率损失与未暴露于冰雹应力的参考模块进行比较。通过比较电致发光图像和参考模块与暴露于冰雹应力的模块的性能,可以提供关于冰雹抵抗性和敏感性的额外见解。本文档旨在帮助选择在特定地区部署的模块,这些地区有较高的冰雹损坏风险,并提供改进模块设计的工具。 [外文原描述]: IEC TS 63397:2022 defines additional testing requirements for modules deployed under applications or in environments where PV modules are likely to be exposed to the impact of hailstones leading to higher stress beyond the scope of the IEC 61215 series. This document aims to assist in the selection of modules for deployment in specific regions that have a higher risk of hail damage and to provide tools for improving module design. The contents of the corrigendum of July 2023 have been included in this copy.
