After the solar cell laminate 2 is fixed inside the first step groove 11, the pressing frame 5 is placed on the top of the solar cell laminate 2 and the frame 1. After the pressing frame 5 is placed on the top of the solar cell laminate 2 and the frame 1, the first elastic sheet 811 at the bottom of the layer 8 is inserted into the fixing groove 12, and the protrusion 13 is inserted into the groove. When the protrusion 13 is inserted into the groove, the layer 8 can rotate around the protrusion 13. When the layer 8 rotates until the second elastic sheet 812 is inserted into the fixing groove 12, the second clamping block 14 can clamp the first clamping block 813 to fix the second elastic sheet 812 inside the fixing groove 12, so that the layer 8 can be fixed on the frame 1, and the layer 8 is pressed on the pressing frame 5 at the same time, and the installation of the four layer 8 is completed in sequence. When the layer 8 is fixed on the frame 1, the four The pressing blocks 9 are placed at the four corners of the top of the frame 1, and the pressing blocks 9 are fixedly installed on the top of the frame 1 by bolts 91, and the installation of the solar photovoltaic module is completed.
