1 Scope
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.
