This part of IEC 60904 specifies methods to: a) capture electroluminescence images of photovoltaic modules@ b) process images to obtain metrics about the images taken in quantitative terms@ and c) provide guidance to qualitatively interpret the images for features in the image that are observed. This document is applicable to PV modules measured with a power supply that places the cells in the modules in forward bias.
