This paper presents a mathematical modelling method of steady-state heat transfer within a glazed flat-plate PV-Thermal collector (GFPVT-C) exposed to solar radiation and using air as a cooling fluid. The main objective of the mathematical modelling is to determine the best configuration of the PV-Thermal collector (such as the optimal thickness of the ventilation duct) and the proper properties of the cooling air (i.e. inlet temperature and flow speed) that allows for an effective reduction of the operating temperature of PV cells. Moreover, with the mathematical model developed, estimations are made of the temperature reduction of PV cells within the glazed PV-Thermal collector (compared to the operating temperature of PV cells inside standard solar PV collectors) and the resulting productivity gain. The results show that the GFPVT-C could make it possible to maintain the operating temperature of the PV cells at 25 °C ± 5 °C, even in hot ambient conditions, which should result in an increase in the PV cells productivity of more than 25 %.
