This study investigates a particular hybrid configuration of Indirect Expansion Photovoltaic Thermal Heat Pump(IEPVT/HP) system based on a detailed thermodynamic and heat transfer analysis. The effect of solar irradiance on the electrical and thermal efficiencies of the system, PVT temperature and the water outlet temperature is studied. Results show that an increase in solar irradiation increases the temperature of the PVT and thus decreases the electrical efficiency of the PVT. It was found that a greater solar irradiance corresponds to an increase in the thermal efficiency of the PVT. For a fixed change in solar irradiance the variance in the thermal efficiency decreases as the solar irradiance increases.
