Abstract: The performance of building integrated photovoltaic thermal (BIPVT) collectors were determined by the PVT efficiency and primary-energy saving efficiency of the three collectors. The first collector, known as Serpentine flow absorber, the second collector, known as Oscillatory flow absorber, the third collector known as Parallel-serpentine flow absorber. In this study, it is assumed that the absorber collectors were attached underneath the flat plate single glazing sheet of polycrystalline silicon photovoltaic module and water has been used as a heat transfer medium in absorber collectors. The testing has been performed for the BIPVT collector under solar radiations at 800 W/m2. The various mass flow rates were introduced and ranging from 0.011 kg/s to 0.041 kg/s. The analysis on the BIPVT collectors have been segregated into three sections comprised of PV efficiency, thermal efficiency and combination of both (PVT efficiency). The results show that Parallel-serpentine flow absorber gave the highest efficiency at mass flow rate of 0.041 kg/s. It produced PVT efficiency about 65% with 13% PV efficiency and of 52% thermal efficiency, also it produced primary-energy saving efficiency from about 76% to 86% at the mass flow rate from 0.011 kg/s to 0.041 kg/s.
