This work is devoted to the synthesis results of the current-voltage characteristic performances obtained by four modelling methods. The aim these models is to emulate the current-voltage characteristics of a photovoltaic module using DC-DC Buck-Boost converter. The first class of the developed methods is based on physical properties. It takes into account the output current of the electrical circuit. The second class uses a system of polynomial equations. It is based on multiple straight lines. The mathematical models are built and validated by a simulation using MATLAB/SIMULINK. The comparative study of the four models demonstrated the performances of the models under study.
