Abstract

Solar energy is a renewable energy source which can be used by thermal and photovoltaic collector technologies. Combining these two technologies can produce heat and electricity simultaneously which are better known as hybrid Photovoltaic/Thermal (PV/T) collectors. The aim of this study is to determine the effect of the differences between the inlet fluid temperatures on the performance of PV/T collector. The difference of the inlet fluid temperatures used in the present study is above and below the ambient temperature. The thermal performance testing used the EN 12975 standard under indoor system with a solar simulator. Meanwhile, the performance of electricity is derived through the comparison of the electrical power produced by PV and heat received by the PV surface. The results showed that the coefficient of heat losses differed by 15% between the two temperature limits used in the performance testing. While the zero efficiency for the temperature of the inlet fluid below the ambient temperature increased 29% compared to the temperature of the inlet fluid above the ambient temperature. Meanwhile the higher the mass flow rate of the inlet fluid, the higher the electrical efficiency generated by the Photovoltaic/Thermal collector. The maximum electrical efficiency reaches 7% when using a fluid mass flow rate of 0.015 kg/s with the inlet fluid temperature below the ambient temperature. There is an increase in electrical efficiency of 2.5% when compared to the Photovoltaic collector alone without using thermal collector.
