In Tochigi Prefecture, located in the northern part of the Kanto region, several ground-mounted power plants utilizing Grace Solar's aluminum alloy solar mounting systems are being constructed smoothly and have begun operations. Grace Solar planned the tilt angles and foundation types of the mounting systems based on precise topographical and meteorological data from the design stage. The high-strength aluminum alloy mounting systems are lightweight yet effectively suppress snow accumulation, ensuring stable operation of the system even during harsh winter conditions. The aluminum alloy mounting systems adopted in this project are treated with a special anti-corrosion coating on the surface, allowing them to adapt to the environment of Tochigi Prefecture, which experiences significant temperature differences and seasonal humidity changes. This effectively delays material degradation and extends the overall lifespan of the system. Going forward, Grace Solar will continue to focus on the characteristics and environmental requirements of each region, supporting more solar power generation projects in Japan and around the world through customized mounting solutions, and providing sustainable and reliable support for renewable energy infrastructure.

In terms of the number and arrangement of drive sources in the drive system, tracking systems are mainly classified into single-point drive and multi-point drive. These two methods are the mainstream choices in large-scale ground-mounted power plants worldwide due to their superior balance of power generation improvement, initial investment, and reliability, making them the solutions strongly recommended by Grace Solar—solar tracking systems. As the names suggest, single-point drive and multi-point drive use rotating drive devices to synchronously rotate the mounting structure. An optimized power transmission design effectively ensures the accuracy of the synchronous movement of the mounting structure. By continuously reducing the angle of incidence of sunlight, they effectively enhance solar yield. Grace Solar's independently developed independent single-row tracking mounting system and multi-point drive tracking mounting system can accommodate slopes of up to 20% in the north-south direction while maintaining a low posture close to the ground, demonstrating excellent wind resistance. The number of modules installed can be adjusted according to the string configuration and the size of the terrain, making it an optimal choice for power plants on irregularly shaped land.

In Chiba Prefecture, the core economic area of Japan, multiple ground-mounted solar power plants utilizing Grace Solar's aluminum alloy solar mounting systems have been completed one after another and are continuing stable operations. Grace Solar's project team conducted detailed geological surveys and systematic structural calculations during the initial planning phase. Their aluminum alloy solar mounting system effectively responds to the soil characteristics of various regions due to its excellent corrosion resistance and structural adaptability. During the construction process, the team strictly adhered to Japan's solar installation standards, strongly supporting the smooth advancement of the project and receiving high praise from partners. This mounting system employs high-quality aluminum alloy materials, ensuring excellent structural strength and outstanding corrosion performance, making it particularly suitable for coastal environmental conditions. Additionally, it achieves a perfect balance between lightweight design and high strength. This not only reduces the foundation load but also significantly improves on-site installation efficiency through modular design, shortening the construction period. Its exceptional long-term durability fundamentally guarantees the power generation revenue throughout the entire lifecycle of the solar power plants, providing customers with long-term and stable investment value.

With the spread of decentralized power generation, rooftop solar systems have become a popular clean energy solution for households and businesses. An excellent mounting system must meet three core requirements: structural strength, environmental adaptability, and ease of installation. Grace Solar leverages years of technological accumulation to provide comprehensive mounting solutions tailored to various roof characteristics, supporting the safe and stable operation of solar systems. We offer a mature product lineup that caters to a wide range of scenarios, from residential roofs to industrial roofs. For tile roofs, we employ a non-destructive installation design and a patented hook system that perfectly fits the structure of the tiles. Our lightweight aluminum alloy mounting systems reduce weight by 45% compared to traditional steel structures while maintaining strength and ensuring safety with a design that evenly distributes loads. For metal roofs, we have developed an adaptive clamp system that accommodates various shapes. With the diversification of solar applications, Grace Solar continues to innovate, providing safer, more efficient, and cost-effective all-scenario solutions, contributing to the promotion of green energy.

Concrete Foundation: The "Gravity Warrior" of Stability and Reliability Advantages: The technology is mature, easy to construct, highly durable, and has a wide adaptability to superstructure structures. Disadvantages: There is a large amount of earthwork involved, the construction period is long, the wet construction method has a certain degree of environmental impact, and restoration to original condition after removal is difficult. Pile Foundation: The "Decisive Factor" that Penetrates Soft Ground Advantages: High bearing capacity, fast construction speed, minimal destruction to the original terrain, particularly suitable for projects in complex geology or mountainous areas. Disadvantages: Requires specialized pile driving equipment, difficult to construct in strata containing many large rocks, relatively high cost. Ground Anchor: The "Surface Anchor" for Rapid Installation Advantages: Extremely fast construction speed, no curing period required, minimal excavation volume, and high environmental compatibility. Disadvantages: Applicable to hard ground, bearing capacity greatly depends on the density and integrity of the in-situ ground, high demands on construction techniques, and relatively high difficulty in quality inspection. There is no universal solution for diverse ground conditions. However, Grace Solar proposes optimal foundation solutions for different ground conditions through extensive project experience, customizing mounting systems that are safe, efficient, and optimize lifecycle costs.
