The invention discloses a solar heat pump and phase change energy storage heat pump combined heating system and a control method. The solar heat pump and phase change energy storage heat pump combined heating system comprises a solar heat collecting unit, a heat pump host unit, a phase change energy storage unit, an indoor tail end unit and a control unit. The solar heat collecting unit, the phase change energy storage unit and the indoor tail end unit are respectively connected with the heat pump host unit, and the control unit is connected with the heat pump host unit and the indoor tail end unit. Through the mode, when the sun radiation strength is high, phase change energy storage can be carried out on redundant heat through the system. Under the condition of low sun radiation strength or at night, the heat stored by phase change energy storage materials heats the interior of the room as a low-temperature heat source, the heating continuity is guaranteed, the system always keeps operating efficiently, and
