Solar Ground Project 872KW , Japan was successfully completed, and the distance of photovoltaic support was measured at the installation site. When the installation site was too hard, or there was too much gravel, it was inconvenient to hammer the column directly into the ground, the ground screw could be selected. Before installation, geological soil testing should be done to determine the appropriate hammering depth. The solar structural design of the support system shall be based on local national standards and load design, taking into account applicable climate hazards and sunshine conditions in other areas.
