地面光伏(PV)模组. 设计质量和型式批准. 第1-4部分: 检测薄膜Cu(In,Ga)(S,Se)2基电池光伏(PV)模组的特殊要求

[中文适用范围]： 该文件规定了适合在露天气候下长期运行的地面光伏组件的设计资质要求。合格模块的使用寿命将取决于其设计、环境以及使用条件。 [外文原描述]： IEC 61215-1-4:2021 lays down requirements for the design qualification of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. The useful service life of modules so qualified will depend on their design, their environment and the conditions under which they are operated. Test results are not construed as a quantitative prediction of module lifetime. This document is intended to apply to all thin-film Cu(In,Ga)(S,Se)2 based terrestrial flat plate modules. As such it addresses special requirements for testing of this technology supplementing IEC 61215-1:2021 and IEC 61215-2:2021 requirements for testing. This second edition cancels and replaces the first edition of IEC 61215-1-4, issued in 2016. This edition includes the following significant technical changes with respect to the previous edition: a. A cyclic (dynamic) mechanical load test (MQT 20) added. b. A test for detection of potential-induced degradation (MQT 21) added. c. A bending test (MQT 22) for flexible modules added. This standard is to be read in conjunction with IEC 61215-1:2021 and IEC 61215-2:2021.
