BS PD IEC TR 60904-14:2020

This document provides guidelines for measurements of the maximum power (P_max) output of single-junction photovoltaic (PV) modules and for reporting at standard test conditions (STC) in industrial production line settings. Such measurements typically:

• Record current-voltage (I-V) data while illuminating the module with a solar simulator;
• Are performed on 100 % of manufactured modules, in order to determine whether they meet nameplate requirements for various bins spanning different power output levels.

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