This paper deals with the analysis and study of performance of solar panels, so we
choose working on the solar panel (module) MSX-50, in addition to improve his power by
tracking the maximum power point, this is done by using boost (step up) choppe
r to obtain
the largest possible capacity of solar panel.
We will determine a mathematical model equivalent to the real solar panel (not ideal)
through studying photovoltaic cells, where we will use the iterative method in addition to
the Newton-Raphson algorithm in order to determine the value serial resistance of module
Rs parallel resistance of module Rp.
As has been the implementation of perturbation and observation p&o algorithm in
addition studying and designing the circuit of step up (boost) chopper, and selection the
components (coil L, capacitor C), based on both the operation frequency f, ripple factor of
output voltage and output current .
Based on the our study, we have performed a modeling process of the solar module
MSX-50 using MATLAB/SIMULINK program, where we designed a graphical user
interface GUI to display the module characteristics and calculate resistance Rp and Rs, in
addition to build an algorithm p&o and design circuit of boost (step up) chopper.
The proposed model has been applied to the ohmic load according to the principle of
the maximum power point tracking MPPT, and discuss the results of two cases wich are
the following the solar module is connected directly to load, connected through chopper
driven by p&o algorithm.
