In this way, between every two adjacent solar greenhouses, the setting of one of the solar greenhouses and its top photovoltaic modules will not affect the lighting of the adjacent solar greenhouses and the photovoltaic modules between the two solar greenhouses, thereby realizing the integration of solar greenhouses and photovoltaic modules. combination to make full use of land resources. As shown in Fig. 3, when the altitude angle of the sun 7 is the smallest, all the photovoltaic modules on the ground can be irradiated by sunlight, and when the sun altitude angle increases, all the photovoltaic modules on the ground must be able to be irradiated by sunlight.

In this way, the photovoltaic support 2 has a triangular structure, and the horizontal right-angled sides of the photovoltaic support 2 form a triangular structure with the vertical support rod 12 and the lower support rod 21, and the overall structure is stable.

Due to the change of seasons, the sun's altitude angle is constantly changing. In order to make the sunlight shine directly on the photovoltaic panel as much as possible, as shown in Figure 5, one end of the hypotenuse 23 of the photovoltaic support 2 is at a right angle to the horizontal of the photovoltaic support 2 through the hinge shaft 24 Side hinge connection, the other end of the hypotenuse 23 of the photovoltaic support 2 is slidingly connected with the vertical right-angle side of the photovoltaic support 2, and the sliding track is an arc line. For this reason, an arc groove is provided on the side wall of the vertical right-angle side of the photovoltaic support 2 . The end surface of the hypotenuse 23 of the photovoltaic support 2 is in contact with the end surface of the vertical right-angled side of the photovoltaic support 2 , and the photovoltaic support 2 has an adjustment mechanism that drives the hypotenuse 23 of the photovoltaic support 2 to swing around the hinge point.
