本技术规范的目的是定义测量和分析特定光伏系统发电量的程序，以评估光伏系统性能的质量。本试验拟在相对较短的时间内（几个相对晴朗的日子）进行。本文件旨在规定一个框架程序，用于比较相对晴朗天气下光伏系统产生的实测功率与预期功率。

The objective of this Technical Specification is to define a procedure for measuring and analysing the power production of a specific photovoltaic system with the goal of evaluating the quality of the PV system performance. The test is intended to be applied during a relatively short time period (a few relatively sunny days). The intent of this document is to specify a framework procedure for comparing the measured power produced against the expected power from a PV system on relatively sunny days.
