Behavior study of PVG via designing of a solar simulator software

We present in this paper a software simulation system with interactive graphic interface for solar systems designed with Matlab-Simulink. In the first part, the system is able to model the five different types of cells / solar modules appear by the characteristics, current-voltage (I-V) and power-voltage (P-V) under different external conditions such as solar irradiance and temperature ambient and the serial resistance Rs. In the second phase of operation of the solar simulator, the system offers for users an easy choice tracking the maximum power point MPPT provided by the solar photovoltaic generator or whatever the conditions under which is the solar panel. Two algorithms are involved either in the simulation module to extract the MPPT, it is perturb and observe (P&O) and the incremental conductance (I.C). With this interactive graphic interface, this solar system software offers flexibility of use for solar professional and researchers.
