Analysis of the performance of the photovoltaic array through the exergy efficiency

Abstract

This work is part of an exergy analysis conducted during the operation of a test-bed hybrid wind/solar generator with hydrogen support, designed and constructed at the Industrial Engineering School of the University of Extremadura, Badajoz (Spain). An exergy balance analysis has been made of the different components of the system, calculating their exergy efficiencies and exergy losses, and proposing future improvements to increase the efficiency of the use of the surplus energy produced by the wind/solar generator. Here we only present the results corresponding to the photovoltaic generator´s exergy analysis.
