Solar Ground Project 860KW , Japan was successfully completed, and the whole set of solar supports were made of aluminum profiles. Hot-dip galvanized steel ground screws with spiral blades were used under the front and rear columns of photovoltaic supports. The construction speed was fast. For the uneven ground environment, the vegetation in the site was protected to the maximum extent, and the site was easy to restore to its original appearance. It was convenient to adjust the upper support and the height of the support could be adjusted with the terrain. It has little impact on the environment, requires less labor, and can be reused.
