Project Spotlight｜Grace Solar Erects Protective Layer for Power Plant along Chiba Coast

Recently, a ground-mounted PV plant utilizing Grace Solar's aluminum alloy mounting system was successfully commissioned in Chiba Prefecture, in Japan's Kanto region. Surrounded by the sea on three sides and frequently hit by typhoons in summer and autumn, Chiba poses stringent demands on the corrosion resistance and structural strength of mounting systems. With its tailor-made aluminum alloy mounting solutions and efficient local services, Grace Solar delivered a stable, high-performing PV plant in this coastal region.

Following grid connection, the plant is expected to generate approximately 1.38 million kWh of electricity annually, equivalent to saving about 552 tonnes of standard coal and reducing CO? emissions by roughly 1,375 tonnes per year. This clean power will be fed into the local grid, supporting Chiba Prefecture's low-carbon energy transition.

Corrosion Defense

Located along Tokyo Bay, Chiba's coastal areas are exposed to year-round sea breezes, making salt-spray corrosion the first hurdle for the mounting system. Grace Solar's aluminum alloy mounts are fabricated from high-weatherability aluminum materials with a specialized anodized surface treatment, maintaining stable corrosion resistance in long-term salt-spray environments. Key connection points feature integrated anti-rust design, forming a complete anti-corrosion chain from materials to structure.

Typhoon Resistance

Situated along the Pacific coast, Chiba experiences frequent typhoons. Grace Solar's aluminum alloy mounts are structurally optimized through dynamic wind load simulations, with reinforced key connection points to prevent structural instability under strong winds. The overall solution enhances wind resistance while maintaining on-site installation efficiency, ensuring the plant is well-prepared for typhoon season.

Soft Ground Foundation

Chiba lies on an alluvial plain with predominantly sandy loam soil and high groundwater levels in some areas. Grace Solar adopted elevated foundation design combined with lightweight aluminum structures, reducing ground-bearing capacity requirements and minimizing deep excavation and backfill work. Even under soft soil conditions, rapid and stable installation was achieved. What Grace Solar delivered in Chiba is not just a power plant, but a proven solution tailored for coastal plain scenarios. From corrosion protection to wind resistance, from foundation to structure, the aluminum mounting system has Proven its "light yet stable" reliability under marine climate conditions.
