IEC 61215-1-2:20 21 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61215-1-2:20 21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。如此合格的模块的使用寿命将取决于其设计、环境和运行条件。测试结果不被解释为模块寿命的定量预测。本文件旨在适用于所有薄膜CdTe基接地平板模块。因此，它解决了该技术测试的特殊要求，补充了IEC 61215-1:20 21和IEC 61215-2:20 21测试要求。本文件根据IEC 61215-1:20 21和IEC 61215-2:20 21定义了测试程序和要求的光伏技术相关修改。第二版取消并取代了2016年发布的第一版IEC 61215-1-2。与上一版相比，此版本包括以下重大技术变更: a.增加了循环（动态）机械载荷试验（MQT 20）。 b.增加了检测电位诱导降解的试验（MQT 21）。 c.增加了柔性模块的弯曲测试（MQT 22）。

IEC 61215-1-2:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 61215-1-2:2021 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 CdTe 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 document defines PV technology dependent modifications to the testing procedures and requirements per IEC 61215-1:2021 and IEC 61215-2:2021. This second edition cancels and replaces the first edition of IEC 61215-1-2, 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.
