Abstract
This work focuses on the performance study of a photovoltaic solar module based on energy and exergy analysis. The experimental data were obtained by precise measurements during a clear sky day March 20, 2018 and a cloudy day March 27, 2018 in the Laboratory of Chemistry and Materials Physics (LCPM) at the Assane Seck University of Ziguinchor, Senegal (12° 34 N, 16° 16 E). Exergy, energy and power conversion efficiency were evaluated for the two days based on measured parameters such as solar intensity, ambient temperature and module temperature. We find that the exergy efficiency varies between 4.5 and 8.93%, the energy efficiency varies between 11.08 and 14.50% and the power conversion efficiency varies between 7.98 and 10.49% throughout the day in the clear sky. While for the cloudy day the exergy efficiency varies between 2.00 and 9.45%, the energy efficiency ranges from 12.41 and 14.5% and the power conversion efficiency varies between 8.93 and 10.46%. Key words: Exergy, energy, photovoltaic module, performance analysis, efficiency, thermal exergy.

Summary
Fossil fuel reserves are declining rapidly due to the increased use of thermal power plants and air pollution associated with the burning of fossil fuels. In the current scenario, there is an urgent need to accelerate research and development of renewable energy technology, especially solar energy, to meet global energy demand. Solar energy applications have been progressively increasing worldwide. This is due to the decrease in the cost of photovoltaic panels with the increasing demand, and the increase in the duration of use (lifetime). Exergy analysis is known by researchers and engineers as an essential tool for evaluating the performance of a PV system with the thermodynamic approach. This analysis demonstrates the efficiency of energy use, it
