标准摘要
[中文适用范围]: 本文件规定了适用于长期在露天气候下运行的地面光伏组件的设计资格要求。如此合格的模块的有用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。在温度超过70°C的气候条件下,建议用户考虑按照IEC TS 63126进行更高温度的测试条件。希望获得光伏产品认证的用户,如果期望寿命较短,建议考虑针对消费电子产品中的光伏设计的测试,如IEC 63163所述。希望确认IEC 61215中测试的特性在制造产品中一致出现的用户,可以考虑使用IEC 62941关于光伏制造质量体系的内容。本文件旨在适用于所有基于CdTe薄膜的地面平板组件。因此,它补充了IEC 61215-1:2021和IEC 61215-2:2021的测试要求。本文件不适用于使用集中阳光的模块,尽管它可以用于低集中模块(1至3太阳)。对于低集中模块,所有测试均使用设计集中度预期的辐照度、电流、电压和功率水平进行。本测试序列的目的是确定模块的电气特性,并尽可能在合理的成本和时间限制内证明模块能够承受长期的户外暴露。加速测试条件基于那些必要重现选定观察到的现场故障的条件,并同样适用于所有模块类型。加速因素可能因产品设计而异,因此并非所有降解机制都可能显现。关于加速测试方法的更多一般信息,包括术语定义,可以在IEC 62506中找到。一些长期降解机制只能通过组件测试合理检测,因为产生故障所需的时间长,且需要在大面积上产生昂贵的应力条件。已经达到足够成熟度以高置信度设置通过/失败标准的组件测试通过添加到IEC 61215-1的表1中纳入IEC 61215系列。相比之下,本系列中描述的测试程序,在IEC 61215-2中,是在模块上进行的。本文件定义了根据IEC 61215-1:2021和IEC 61215-2:2021的测试程序和要求的PV技术相关修改。 [外文原描述]: 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.
