Automatic supervision of a 6 kWc photovoltaic plant composed of monocrystalline and amorphous panels

In this article, we are going to propose the monitoring on a PV plant composed by monocrystalline and amorphous panels. The aim is to insure good performances of the installation and its profitability. The purpose of this work consists to diagnose the panels faults and, in certain cases to locate the faults by using the model and the measurements and by taking into account the MPPT (Maximum Power Point Tracking) of the inverters. The development of software fault detection on the PV plant of our laboratory is performed under Matlab / Simulink environment.
