During operation, the photovoltaic panels 2 and the herringbone wedge plates 3 are alternately inserted into the inner side of the U-shaped frame 1. When an appropriate number of photovoltaic panels 2 are installed in the U-shaped frame 1, the fixed bottom plate is inserted between the two insertion slots 13. Then, the fixing plate 4 is sleeved on the outer side of the limiting rod 61 through the through hole 45. Then, the threaded rod 6 is screwed to be threadedly connected with the threaded hole 44, so as to cooperate with the limiting rod 61 to guide and limit the fixed bottom plate, and further drive the fixing plate 4 to press the photovoltaic panel 2, so as to cooperate with the first wedge block 12, the second wedge block 43 and the herringbone wedge block to upwardly press and tightly fit the photovoltaic panel 2 against the top of the inner cavity of the insertion slot 13 to stably limit the photovoltaic panel 2, so that the installation of the photovoltaic panel 2 is more convenient, and it is not necessary to use multiple bolts to complete the stable installation, thereby improving the installation efficiency of the photovoltaic panel 2.
