Detection and diagnosis of PV system faults

Abstract

The photovoltaic systems are gaining more importance as reliable energy producing systems, due to the fact of that the solar energy is green and renewable. In spite of the instability of electricity generation and the low efficiency, the PV systems have relatively long life span. Similar to any other system, the PVS endure losses and are exposed to failures with different significance. Hence a diagnosis system is required to monitor and detect the faults’ existence. This project concern is developing a fault diagnosis system with the purpose of identifying the occurrence of the most common faults in a PV system based on the current and voltage assessment under different conditions.
