This utility model applies to the field of
greenhouse technology, providing a photovoltaic
greenhouse that couples multiple uses of light, heat,
electricity, water, and air. The photovoltaic
greenhouse has wind-climbing walls on its side walls and includes a truss main body. The top of the truss main body has a
gable roof, with a top-opening window on one side. Photovoltaic panels are installed on the side of the
gable roof opposite the top-opening window. Inside the truss main body, there is a triangular inner arched
canopy, or a semi-circular inner arched
canopy below the truss main body. Vertical ventilation roll-up rods are provided on the sides of the triangular or semi-circular inner arched
canopy. A retractable insulation
blanket is laid on top of the triangular or semi-circular inner arched canopy. This solution couples the solar thermal utilization of the closed
greenhouse effect with the photovoltaic solar electrical utilization, achieving multi-effect utilization of
solar energy in the greenhouse, doubling the comprehensive
utilization rate of
solar energy, and also providing temperature,
humidity, and light regulation functions.
