   The small PV system installed on the roof of the building of the Faculty of Electrical Engineering and Information Technology in Bratislava has been monitored and its long-term behaviour investigated. After three year operation the changes in PV module properties have been checked and the ageing process has been evaluated using the polarization index dependence and charging current measured and compared on aged and non-aged modules.

Keywords: PV module, power performance, degradation, high voltage stress
