Exergy analysis of a solar-hydrogen hybrid energy system

Abstract

In this study, exergy analysis of a photovoltaic-hydrogen production system established at the Clean Energy Center(CEC), in Denizli, Turkey has been investigated. Exergy analysis for photovoltaic systems is necessary for studying the PV performance and possible improvements. The exergy efficiency comparison of the fixed tilt(45o south) and mounted on solar trackers photovoltaic modules, is calculated here by the experimental datas taken from the system located in the CEC in Denizli, Turkey, at 37°46' North latitude and 29°05' East longitude. The experiments were carried out from 08:00 am to 18:00 pm, on July 13, 2010. It is seen that exergy efficiency of the fixed tilt PV module vary between 9,3% and 11,2%, while the exergy efficiency of the mounted on solar tracker PV module vary between 9,7% and 11,9%. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.
