Degradation of AEG PV Modules Parameters After 20 Years of Operation

Abstract

Si-based photovoltaic (PV) modules are now a mature technology and their lifetime is in the range of 25 to 30 years in the operating field. During this period, many times, it is required to find out the health of the PV modules in the field in order to estimate the performance degradation after certain time period. In this paper, the parameters degradation of one AEG PV module (monocrystaline Si-based), operating for a period of just more than 20 years, is studied and compared to their initial reference data. The considered PV module parameters are, firstly, analytically analyzed and then estimated from the experimentally measured module characteristics. The characteristics were measured for the considered PV module twice. The first one was during the first year of purchasing and installing the PV module, while the second one was after a period of about 20 years from installation. The results showed the effect of 20 years aging on the considered PV module.
