A solar greenhouse power generation system installed outside a greenhouse comprises a heat storage device (C) arranged on the top space of a greenhouse bearing wall, a heat insulation material (C5) and vacuum glass or a hollow transparent plastic plate or a multilayer plastic film (C2) are wrapped by a shell (C1) to form a box body with a trapezoidal section, the bottom of the box body is abutted against the greenhouse bearing wall, the other inclined surface of the box body is abutted against the rear slope surface of the greenhouse to form a stable structure, a plate-type or tubular heat absorber (E11) for a heat pump is arranged below the inner part in the box body, when the plate-type heat absorber is used, a partition plate (C6) is erected on the plate-type heat absorber, a powder heat storage material (C3) is placed between the partition plate (C6) and the vacuum glass or the hollow transparent plastic plate or the multilayer plastic film (C2), and the vacuum glass or the hollow transparent plastic plate or the multilayer plastic film (C2) is firmly adhered and the heat, when a tubular heat absorber is used, the powder heat storage material (C3) can directly wrap the heat absorption tube, and when the powder heat storage material (C3) is not adopted in the tubular heat absorber, a heat absorption coating (C7) is adopted, so that solar photovoltaic radiant heat is obtained by utilizing a heat storage device (C) formed by matching idle spaces on a bearing wall of a greenhouse (B), and a heat pump power generation device (E) manufactured in a matched manner is used for generating power for a civil house, or a heat pump heat accumulation heating device (F) manufactured in a matched manner is used for obtaining high-value medium heat for heating for the civil house; the heat pump power generation device (E) comprises a plate-type or pipe-type heat absorber (E11) for a heat pump, which can form an integral power generation system with a heat storage device (C), a generator (E1), a pneumatic motor (E2), a pump heat exchanger storage tank (E6), a compressor (E9), a fully-wrapped high-efficiency heat exchange tube (E12), a collecting tank (E17), a refrigerant liquid storage tank (E19), a tail gas heat exchanger (E20), a condenser (E21), a heating tube (E22), refrigerant liquid conveyed by the compressor (E9) sequentially passes through a fourth pipeline (E10), a pump heat exchanger storage tank (E6), a fifth pipeline (E15), a refrigerant liquid storage tank (E19), a control valve (E18) and a tail gas heat exchanger (E20), and enters the plate-type or pipe-type heat absorber (E11) for compressing and expanding, so that the refrigerant liquid is stored in the heat pump-type or pipe-type heat absorber (E11) by taking air heat storage device or internal heat storage material (C3) for radiation heat storage, therefore, heat is gathered in the pump heat exchanger, gathered medium heat exchanges heat with low-temperature liquid which is injected into the inner pipe (E12-1) through the pump (E14) and the check valve (E16) and is lower than the boiling point of water through a gap between the outer pipe (E12-2) and the V-shaped heat conducting fin (E12-3) outside the inner pipe (E12-1) of the fully-wrapped high-efficiency heat exchange pipe (E12), medium pressure generated by gasification is accumulated in the pump heat exchanger storage tank (E6), and the accumulated medium pressure pushes the pneumatic motor (E2) to drive the generator (E1) to operate through the control of the second pipeline (E4) and the pressure flow controller (E8) to generate electricity.
