“…It was observed that the energy and exergy efficiencies were varying between (6% to 9%) and (8% to 10%), respectively. Mehmet Özalp et al [5] evaluated the energy efficiency of the PV panel for several years, with the result coming in 2009 is 9.25% to 18.32%, and the energy efficiency in 2003 as calculated by Patella ranged between 9.41% and 9.41%, 18.64%, the excessive efficiency presented by Sahin et al From 6.58% to 19.99%.•Erhan Arslan et al [6] analyzed the effect of energy and exergy measurements of a naturally ventilated PV roof solar. The system's thermal, electrical, and overall energy efficiencies were 18-50 %, 13-18 %, and 35-67 %, respectively, overall exergy competencies of the-RSC system ranged from 0.1-0.9 %, 14-20 %, and 15-21 %.…”

The average exergy efficiency of the case 2p*2p compared with case 2s*2s was55.9%.• The average exergy efficiency of the case 2p*2p compared with case 4p was63.69%. • The average exergy efficiency of the case 2p*2p compared with case 3p*1s was78.9%. It is well known that photovoltaic (PV) can be connected in parallel, series, and parallel series. In this study, four PV panels are connected in four different ways, i.e., 4panels parallel (4p), 3panels parallel*1panel series (3p*1s), 2panels parallel*2panels parallel (2p*2p) connected in series, and 2panels series *2panels series (2s*2s) connected in parallel, to determine the best PV panels configuration for supplying DC power to the Variable Speed Compressor (VSC) with the highest average exergy efficiency and minimum exergy losses under sunny daylight hours. Experimental data is used to calculate the exergy efficiency of the mentioned configurations. The best results are delivered by (2p*2p) configuration with average exergy efficiency of 43.77% and exergy efficiency of 88.05%. Whereas the percentage of improvement for the average exergy efficiency of this configuration compared with the (2s*2s), (4p), and (3p*1s) are (55.93%), (63.69%) and (78.9%) respectively.

“…As a result, there has been enormous interest in exergy calculations, considering the irreversibility and the supply of energy in the system. Thus, many scientists have conducted theoretical and experimental studies in this field (Özalp and Bayat, 2017). Rajput et al (2016) developed a mathematical model to calculate solar cell temperature, hot spot temperature and module efficiency in opaque and semitransparent mono crystalline silicon (sc-Si) PV module.…”

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%.
