The first study on a PV/T system was presented by Martin Wolf in 1976 [2]. A large number of investigations on PV/T collectors/systems have been subsequently conducted. For example, Raghur-aman [3] presented two separate one-dimensional mathematical models for predicting the performance of water and air PV/T flat plate collectors and compared the results with the experimental data. Design recommendations were also made for the maximiza-tion of the total energy extracted from the collectors. Similarly, Bergene and Lovvik [4] presented a detailed model for predicting the performance of a PV/T system. Sandnes and Rekstad [5] con-structed a PV/T collector by laminating single-crystalline silicon cells onto a black plastic absorber plate. The photovoltaic and ther-mal performances of the PV/T collector were experimentally and numerically studied in their work. Kalogirou and Tripanagnostopo-ulos [6] presented a TRNSYS simulation for PV/T systems for domestic hot water production with both thermosyphon and forced water flow. In addition, an economic analysis of the PV/T
