New energy utilization like sober has been developed quickly during these years. In this paper, a new combined solar photovoltaie/thermal （PV/T） system was introduced. Gravitational loop heat pipe was applied in this solar system to increase the overall solar utilization efficiency. The principle of the PV/T system was introduced. The new combined solar system was built, tested and analyzed in the tab. The steady-state charac-teristics of the new system were studied such as the effects of solar radiation intensity, air temperature, air ve- locity and evaporate temperature of heat pump. This new system will be of practical use for the solar energy design and performance evaluation in the architecture.
