It should be noted that the specific implementation described here is only used to explain the utility model, and is not used to limit the utility model.
[0020] like Figures 1 to 4 As shown, the lightweight photovoltaic assembly of the utility model comprises: a laminate 1, wherein the laminate 1 is a structure formed by laminating 1.6mm+1.6mm glass and an adhesive film after serial welding of battery sheets.
[0021] The left and right sides of the laminate 1 are set as long frame components 3, and the upper and lower sides of the laminate 1 are set as short frames 2; the long frame component 3 includes a long frame 3.1, and the two ends of the long frame 3.1 are long frame corner codes 3.2, and two intermediate beam connecting parts 3.3 are also set on the long frame 3.1; the short frame component 2 is first installed with the laminate 1, and the short frame 2 is connected to the long frame component 3 through the long frame corner code 3.2 to form a photovoltaic component.
[0022] The two intermediate crossbeam connecting pieces 3.3 and the long frame 3.1 are riveted together; the intermediate crossbeam connecting piece 3.3 includes barbs 3.3.1, a weight-reducing cavity 3.3.2 and rivet holes 3.3.3; the barbs 3.3.1 are arranged on the intermediate crossbeam connecting piece 3.3 to increase resistance and prevent it from falling off from the cavity; the weight-reducing cavity 3.3.2 is arranged to reduce weight and reduce costs; the rivet holes 3.3.3 are arranged for connecting with the long frame 3.1.
[0023] An intermediate crossbeam 4 is also provided below the laminate 1 (the intermediate crossbeam 4 is installed below the laminate 1 through silicone), and the intermediate crossbeam 4 is connected to the long frame assembly 3; the intermediate crossbeam 4 includes an upper and lower mounting surface 4.1, and a cavity 4.2 is provided between the upper and lower mounting surfaces 4.1, and a boss 4.3 is provided in the cavity 4.2.
