In this study, we estimated the energy saving performance of Photovoltaic Thermal Hybrid System (PVT system) by the computer simulation. PVT system is a device that combines solar thermal collector and photovoltaic cell. We inputted 12 houses data into our simulation. These data are actual general houses data in a year. This simulation results show that electrical efficiency and thermal efficiency of PVT system depend by water flow. PVT system has three type of PV which are crystalline, multicrystalline and amorphous silicon. The efficiency of PVT system of crystalline silicon is higher than the others. Rate of primary energy reduction of PVT system is better than that of PV cell, solar water heater or PV cell (3m^2) + solar water heater (3m^2). Therefore PVT system has the better performance of energy saving.
