For mountain photovoltaic projects, it is difficult to cope with the rugged terrain. At present, a 98MW mountain photovoltaic project is under intense shipment. The project is located in a mountainous area in Yamaguchi Prefecture, Japan. After completion, it may become the largest photovoltaic power station in the region.

Yamaguchi Prefecture is located in the westernmost part of Japan's Honshu Island. More than 90% of the land in the territory is mountains and hills, and the terrain conditions are extremely complex. This project involves more than 200 inclination angles. In order to avoid shadows and improve the efficiency of the starting point, the GraceSolar team adopted a flexible and easy-to-install double-column piling structure, and designed 6 arrangements to deal with it.


About the solution

GS-Smart Ground Mounting System Solution(Double Column Piling) is suitable forlarge-scale ground power plants in various terrains.It adopts open carbon steel cross section as support.With pile driving equipment, the installation speed can be increased by 50% compared with that ofscrew bolt, and the installation steps of foundationand column are avoided, which greatly saves installation time and makes installation easier. Its rotating head can realize large angle rotation in three directions, It is suitable for installation on variousslopes and wavy ground.


·Installation is convenient, compared with ground bolts, the installation speed can be increased by 50%;

·The head can be flflexibly rotated, which can overcome the adverse effects of ground tilt.

It has been successfully applied in large-scale ground photovoltaic power stations in mountainous areas such as Japan, Taiwan, and the Balkans.


With the increasing scarcity of suitable land resources, large-scale ground photovoltaic power stations have gradually shifted from plains and gobi desert to mountainous areas. With its rich experience, GraceSolar will provide global customers with solutions and services tailored to local conditions to help the construction of local clean energy.
