本文件规定了地面光伏系统的设计资格要求 适合在露天气候下长期运行的模块。模块的使用寿命 因此，合格与否取决于它们的设计、环境以及它们所处的条件 都是手术。测试结果不能被解释为模块寿命的定量预测。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document 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.All current amendments available at time of purchase are included with the purchase of this document.
