  • Photovoltaic(PV) cells are one of the most important resources of renewable energy. In this paper, anexperimental comparative performance study between PV module and water-cooled photovoltaic/thermal (PV/T) solar system at  different  flowrates of (0.5, 1, 1.5, 2) L/min is presented andincluding their thermal and electrical performances. The experiments werecarried out under outdoor exposure to the climate of Hilla, Iraq(32.46 °N, 44.42 °E). Solar irradiance, the temperatures on the front surfaces and back sheet of PV and PV/T solar system, flowing water, ambient air and wind speed are measured. In addition, the electrical power of PV module and PV/T solar system is measured.

    The results show that the maximum enhancement ratio of electrical efficiency of the PV/T solar system compared with PV module is 18.86% in March at flowrate of 2 L/min. The minimum enhancement is 13.36 % in July at flowrate of 0.5 L/min. The maximum overall efficiency improvement ratio of PV/T solar system compared to PV module is 81% in March at flowrate of 2 L/min while the minimum improvement is 74.08% in July at a flowrate of 0.5 L/min. The maximum average of cooling water temperature rise is 11.28 °C at a flowrate of 0.5 L/min in March, while the minimum is 2.69 °C at a flowrate of 2 L/min in July.
