Abstract

This paper focuses on the description of the analysis techniques of the PV module based on amorphous solar cells under indoor aging tests according to IEC 61646. The goal of this work is the knowledge about the dynamic characteristics of the PV module. The effect of indoor aging on the PV module performances will be also described. For this purpose, a simple technique, based on the analysis of the behavior of PV module biased by an AC signal on dark conditions, has been described and experimented. This technique allows evaluating easily and quickly some parameters such as the series, the parallel resistances and the capacitance affecting the dynamic AC model of the PV module.
