IEC 61215-1:20 21作为IEC 61215-1:20 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 61215-1:20 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地面平板模块材料，例如晶体硅模块类型以及薄膜模块。它不适用于非长期应用的系统，如安装在遮阳篷或帐篷中的柔性模块。IEC 61215-1第二版取消并取代了2016年发布的IEC 61215-1第一版。与上一版相比，此版本包括以下重大技术变更: a.增加了取自IEC TS 62782的测试。 b.增加了一项来自IEC TS 62804-1的试验。 c.增加了柔性模块所需的测试方法。这包括增加弯曲测试（MQT 22）。 d.添加了关于如何对双面光伏组件执行IEC 61215设计认证和型式认证的定义、参考文献和说明。 e.澄清与功率输出测量相关的要求。 f.在200次热循环期间向接线盒添加配重。 g.要求根据IEC TS 62915进行复检。 h.从IEC 61215系列中删除标称模块操作测试（NMOT）和相关的NMOT性能测试。

IEC 61215-1:2021 is available as IEC 61215-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61215-1:2021 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 terrestrial flat plate module materials such as crystalline silicon module types as well as thin-film modules. It does not apply to systems that are not long-term applications, such as flexible modules installed in awnings or tenting. This second edition of IEC 61215-1 cancels and replaces the first edition of IEC 61215-1, published in 2016. This edition includes the following significant technical changes with respect to the previous edition:
a. Addition of a test taken from IEC TS 62782.
b. Addition of a test taken from IEC TS 62804-1.
c. Addition of test methods required for flexible modules. This includes the addition of the bending test (MQT 22).
d. Addition of definitions, references and instructions on how to perform the IEC 61215 design qualification and type approval on bifacial PV modules.
e. Clarification of the requirements related to power output measurements.
f. Addition of weights to junction box during 200 thermal cycles.
g. Requirement that retesting be performed according to IEC TS 62915.
h. Removal of the nominal module operating test (NMOT), and associated test of performance at NMOT, from the IEC 61215 series.
