Comparison between the different numerical models and determination of parameters characteristics of photovoltaic module of LRAER

ABSTRACT The objective of this paper is to establish a systematic approach to the comparison of the performance of mathematical modeling models of photovoltaic systems most used in the literature. This desired performance is normally evaluated under the standard test conditions (STC), where an average solar spectrum of AM 1.5 is employed, the sunshine is normalized to 1000W / m², and the cell temperature is set equal to 25 ° C. In this paper, two methods of modeling the cell or the panel are presented. These two methods are based on the data provided by the manufacturers of solar cells or panels, which will be presented. A comparison of the traditional modeling method for an electrical circuit that is equivalent to a photovoltaic cell or panel is called the Madison Model (MM), with the Cenerg Model, under the term (MC). The mathematical modeling process is realized with the two models (MM and MC) for the cases, a diode, two diodes and for the grouping of the photovoltaic panels of the LRAER. Thus, we try to determine the parameters of the mathematical models (MM and MC) that are used. This is done with the aim of comparing their precisions by comparing the results of simulations obtained and then by comparing them with the data of the experimental data acquisition system for the ATERSA 75 W modules of the LRAER, of UNAA. It is important to note at the end of this summary that the main objective of this paper is to compare the mathematical models (MM and MC) and the comparison of the different technologies of crystalline silicon, amorphous silicon, CIS and Of CdTe does not fit into these objectives, although sometimes there is a shift in this direction.
