本文件提供了量化单片集成光伏组件功率输出永久性变化的测试方法，该变化可能由某些潜在的局部阴影条件引起。有三种测试可用，分别代表使用条件、误用和最严重的误用。本文件适用于带有一个串联电池组或多个串联电池组（依次并联）的单片集成光伏组件。本文件不适用于由独立电池互连而成的光伏组件。 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 provides test methods for quantifying the permanent change in a monolithically integrated PV module's power output that may result from some potential partial shade conditions. Three tests are available, representing conditions of use, misuse, and most severe misuse. This document is applicable to monolithically integrated PV modules with one series-connected cell group or with multiple series-connected cell groups that are in turn connected in parallel. This document is not applicable to PV modules formed by the interconnection of separate cells.All current amendments available at time of purchase are included with the purchase of this document.
