IEC 61215-1-1:20 21作为IEC 61215-1-1:20 21 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。 IEC 61215-1-1:20 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。在第98百分位工作温度超过70°C的气候条件下，建议用户考虑在IEC TS 63126中描述的更高温度测试条件下进行测试。本文件旨在适用于所有晶体硅接地平板模块。第二版取消并取代了2016年发布的第一版IEC 61215-1-1。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）。 d.增加了应力特异性稳定化程序-BO LID（MQT 19.3）。 e.增加了接受PID测试的模块的最终稳定程序

IEC 61215-1-1:2021 is available as IEC 61215-1-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61215-1-1:2021 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. In climates where 98th percentile operating temperatures exceed 70 °C, users are recommended to consider testing to higher temperature test conditions as described in IEC TS 63126. This document is intended to apply to all crystalline silicon terrestrial flat plate modules. This second edition cancels and replaces the first edition of IEC 61215-1-1, 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.
d. A procedure for stress specific stabilization – BO LID (MQT 19.3) added.
e. A final stabilization procedure for modules undergoing PID testing added
