A photovoltaic-phase change material (PV-PCM) system has been developed to reduce photovoltaic (PV) temperature dependent power loss. The system has been evaluated outdoors with two phase change materials (PCMs); a salt hydrate, CaCl2 center dot 6H(2)O and a eutectic mixture of fatty acids, capric acid-palmitic acid in two different climates of Dublin, Ireland (53.33N, 6.25W) and Vehari, Pakistan (30.03N, 72.25E). Both the integrated PCMs maintained lower PV panel temperature than the reference PV panel. Salt hydrate CaCl2 center dot 6H(2)O maintained lower PV temperature than capric-palmitic acid at both the tested sites. The lower PV temperatures effected by the use of the PCMs prevented the associated PV power loss and increased PV conversion efficiencies. Both the PCMs attained higher temperature drop in warm and stable weather conditions of Vehari than the cooler and variant weather conditions of Dublin. (C) 2015 Elsevier Ltd. All rights reserved.
