Figure 1 is a schematic view of the bracket rail, the bracket rail 1 is cut into 30cm each, which facilitates the packaging and transportation of the bracket rail. According to the design scheme of the household photovoltaic power generation system, all the installation and fixing positions of the roof hooks 3 to be installed are determined on the roof plane 2, and the corresponding positions on the roof plane 2 are marked with a marker.

Since the roof tiles are stacked one by one, the mounting position of each row of roof hooks can be moved up and down slightly so as to be able to be fixed to the cement foundation of the roof through the overlapping areas of the upper and lower rows of roof tiles. The corresponding roof tiles are first uncovered at the corresponding signs, and then the pre-designed general-purpose roof hooks 3 are fixed on the cement foundation of the roof with the expansion screws 4, and finally the uncovered roof tiles are returned to the original position. Pay attention to the overlapping of the upper and lower tiles and the closeness of the overlapping of the left and right adjacent tiles to prevent the roof from leaking due to the uncovering of the tiles. Figure 3 is a schematic view of the installation of the roof hook, and Figure 4 is a schematic view of the distribution of the roof hook.
