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.
