The invention discloses an efficient compact heat storage type heat pump system driven by solar photovoltaic photo-thermal. Main devices comprise a three-medium heat accumulator, a compressor, a solar photovoltaic photo-thermal assembly, an expansion valve, a refrigerant pipeline, an external heat exchange fluid pipeline, a water pump, a valve and a heat supply tail end. Solar photovoltaic photo-thermal is adopted to drive the heat pump compressor to store heat, the stored heat is released when heat is needed in the peak period of a power grid, and energy consumption is low; the solar photovoltaic photo-thermal assembly serves as an evaporator, the evaporation temperature of a refrigerant is increased, and the heating efficiency of the heat pump is improved; the condenser and the heat storage device are integrated into the three-medium heat accumulator, the heat exchange temperature difference is small, and the heat storage and release efficiency is high. Solar photovoltaic photo-thermal, the heat pump and th
