Photovoltaic (PV) systems have to be designed to produce power over a long and predictable service lifetime. This paper aims to understand what caused a PV plant’s production collapse after only two-and-a-half years of service. An experimental examination has been carried out paying attention to the PV modules of the system. These were found to be faulty, providing a zero voltage even in conditions of good solar irradiation. Considering the type of failure encountered, this work can be considered interesting both for the methodology applied to identify the failure mechanism and for the type of failure which is not among the most presented and discussed in the literature.

Abstract
Photovoltaic (PV) systems have to be designed to produce power over a long and predictable service lifetime. This paper aims to understand what caused a PV plant’s production collapse after only two-and-a-half years of service. An experimental examination has been carried out paying attention to the PV modules of the system. These were found to be faulty, providing a zero voltage even in conditions of good solar irradiation. Considering the type of failure encountered, this work can be considered interesting both for the methodology applied to identify the failure mechanism and for the type of failure which is not among the most presented and discussed in the literature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
