The invention relates to a
ray adjustment structure of a
photovoltaic power generation greenhouse and an adjustment method thereof, and belongs to the field of agricultural greenhouses. The roof of the
greenhouse is of a sawtooth-shaped structure, and the long edges are arranged on the sun-facing side, the short edges are arranged on the dark surface, and a plurality of
solar cell modules are arranged on the sun-facing surface, a frame is arranged on each
solar cell module, a rotating shaft is arranged on the frame, the angle of the
solar cell modules is adjustable, reflecting
layers are arranged on the back faces of the solar
cell modules, and sealing transparent glasses are hermetically connected to the lower surfaces of the solar
cell modules, and transparent glasses are arranged on dark surface side. The angle of the solar
cell modules at the top of the
solar greenhouse can be adjusted according to requirements, and the
solar light rays can be changed or refracted, so that
sunlight illumination and ventilation are carried out in the
greenhouse, the
irradiation time and the area of the photovoltaic cell can be guaranteed, and the
photosynthesis of crops in the greenhouse can be ensured.
