Energy and exergy analyses were applied to each component of the system (e.g. pumps heat exchanger PV-T PEME and separation unit (SPU)) and the whole system to assess the system performance. The mathematical modelling of the whole system along with its main components except for the SPU was done using the Engineering Equation Solver (EES) software package while the SPU was modelled through the ASPEN Plus. A detailed modelling of the PEME was also included. The effects of the PV-T and PEME parameters on energy and exergy efficiencies of the system were evaluated while the improvement potentials and scale up options were discussed. Energy and exergy efficiencies of the proposed system at the optimum operation of the PEME and under average climatic conditions in the city of Izmir Turkey were determined to be 27.8% and 3.1% respectively. Energy and exergy efficiencies of the system were mainly regulated by the PV-T and PEME whose energy and exergy efficiencies were 40.6% 56.6% and 13.8% 14.1% respectively. Effective PEME parameters for energy and exergy efficiencies of the system were membrane conductivity membrane thickness anode catalyst and the operation temperature of the PEME. By changing the PV-T and PEME parameters and by scale-up energy and exergy efficiencies of the system could be improved. © 2021 Elsevier B.V.
