Experimental Exergetic And Energetic Analysis of Different (PV) Array Configurations

Abstract

ries. In this study, four PV panels are connected in four different ways,i.e., 4panels parallel (4p), 3panels parallel*1panel series (3p*1s), 2panelsparallel*2panels parallel (2p*2p) connected in series, and 2panels series *2panelsseries (2s*2s) connected in parallel, to determine the best PV panels configurationfor supplying DC power to the Variable Speed Compressor (VSC) with the highestaverage exergy efficiency and minimum exergy losses under sunny daylight hours.Experimental data is used to calculate the exergy efficiency of the mentionedconfigurations. The best results are delivered by (2p*2p) configuration withaverage exergy efficiency of 43.77% and exergy efficiency of 88.05%. Whereasthe percentage of improvement for the average exergy efficiency of thisconfiguration compared
