地面光伏组件.设计鉴定和型式认证.第1部分:试验要求

[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陆上光伏组件的设计资格要求。通过资格认证的组件的使用寿命取决于其设计、环境和运行条件。测试结果不能被解释为组件寿命的定量预测。 在运行温度超过70°C的气候条件下，建议用户考虑按照IEC TS 63126进行更高温度条件下的测试。对于预期寿命较短的光伏产品，建议用户考虑按照IEC TS 63163（正在制定中）进行适用于消费电子产品的光伏测试。希望确认IEC 61215中测试特性在制造产品中一致性的用户，可以参考IEC 62941关于光伏制造质量体系的内容。 本文件适用于所有陆上平板组件材料，包括晶体硅组件类型和薄膜组件。不适用于非长期应用系统，如安装在遮阳篷或帐篷中的柔性组件。 本文件不适用于聚光太阳光使用的组件，但可用于低聚光组件（1至3个太阳光）。对于低聚光组件，所有测试均使用设计聚光水平下的辐照度、电流、电压和功率等级进行。 本文件不涉及带有集成电子设备的光伏组件的特殊性，但可作为测试此类光伏组件的基础。 本测试序列的目的是确定组件的电气特性，并在合理的成本和时间限制内尽可能证明组件能够承受长期的户外暴露。加速测试条件基于重现选定观察到的现场故障所需的经验条件，并平等应用于所有组件类型。加速因素可能因产品设计而异，因此并非所有退化机制都可能显现。关于加速测试方法的更多一般信息，包括术语定义，可参考IEC 62506。 由于产生故障所需的时间长以及在大面积上产生应力条件的成本高，一些长期退化机制只能通过组件测试合理检测。已达到足够成熟度以设定高置信度通过/失败标准的组件测试通过添加到表1中纳入IEC 61215系列。相比之下，本系列和IEC 61215-2中描述的测试程序是在组件上进行的。 [外文原描述]： IEC 61215-1:2021 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 61215-1:2021 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. The contents of the corrigendum of May 2021 have been included in this copy.
