DIN IEC/TS 61724-2 VDE V 0126-25-2:2016-06

This Technical Specification defines a procedure for measuring and analyzing the power production of a specific photovoltaic system The goal is to specify a framework procedure for comparing the measured power produced to the expected power from a PV system on sunny days. This test procedure is intended for application to grid-connected photovoltaic systems that include at least one inverter and the associated hardware, and is expected to be applied to medium- or large-scale projects. It may be applied to any PV system, including concentrator photovoltaic systems, using the irradiance that is relevant to the performance of the system.
