FIG. 1 is a perspective view showing a solar power generation device of the present invention. The solar power generation device 1 is formed by fixing a solar cell module 2 on a gantry 3. The gantry 3 is fixed on a pile foundation 4 formed by driving a shaped steel or the like into the ground substantially vertically. At the upper end of the pile foundation 4, a strut-pile connection portion 5 is installed. The strut-pile connection portion 5 is installed at the upper end of the pile foundation 4 so that the flange portion of the channel steel faces downward, and the flange portion and the pile foundation are fastened by bolts. A hole for fastening the support is formed on the upper surface of the support-pile connection portion 5.
