Influence of Climatic Parameters on the Performance of Polycrystalline and Monocrystalline Silicon Photovoltaic Solar Modules: The Case of the City of Koudougou

Monocrystalline and polycrystalline silicon-based modules are commonly used in Burkina Faso, particularly in the city of Koudougou, to generate electricity. However, climatic parameters affect the performance of these modules. It is therefore necessary to conduct a comparative study between polycrystalline and monocrystalline silicon-based photovoltaic solar modules. The objective of this work is therefore to determine the module best suited to the city of Koudougou's climatic context. In this study, climatic parameters such as sunshine and temperature were considered. Thus, based on the mathematical model of a photovoltaic module, a simulation was carried out in the MATLAB/Simulink environment an experimental study of the two types of modules was conducted. The results obtained after the simulations and experiments were compared. Analysis of the results for the two module technologies shows that during the period of the day when the temperature is high, the polycrystalline silicon-based module performs better than the monocrystalline silicon-based module. However, during periods when the temperature is lower, the monocrystalline module performs better than the polycrystalline module. Considering the average daily power output for October 2024, it appears that the monocrystalline silicon-based module performs better than the polycrystalline silicon-based module. In general, monocrystalline modules offer better technical performance than polycrystalline modules in the climate of the city of Koudougou.
