The IFEMA exhibition center in Madrid is already prepared! Grace Solar warmly invites everyone to the Genera exhibition on November 18, where we look forward to seeing the future of solar mounting technology together. As Spain and Europe accelerate their transition to renewable energy, we will present our entire series of durable solutions: ✔️ Intelligent Tracker System — Smart technology designed to achieve maximum power generation across diverse terrains ✔️ Ground Mounting System — Provides a solid foundation for large-scale solar power plants ✔️ Roof Mounting System — A multifunctional penetration prevention solution applicable to commercial and industrial roofs Please visit us at booth H3D01. This is an opportunity to interact directly with our technology experts, see live demonstrations of our products, and gather information to build a solid foundation for your next project. Venue: IFEMA Exhibition Center, Madrid, Spain Date: November 18-20, 2025

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.

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.
