[Information] Module Upgrade and Replacement Manual

As we welcome the new year, we sincerely thank you for your journey towards building a sustainable future with solar energy. This year, we will continue to be a reliable support for our customers and the future of the Earth. We hope that 2026 will be a year filled with light and innovation.

In Chiba Prefecture, located in the Kanto region of Japan, multiple ground-mounted power plants using Grace Solar's aluminum alloy solar mounting systems have been successfully completed and have begun transmitting power. To address the high salinity and humidity of the marine climate, Grace Solar has specially improved the surface treatment and structural sealing of the mounting systems. The aluminum alloy body is coated with a multi-layer anti-corrosion coating, and salt damage prevention designs are employed at critical joint areas. This effectively prevents the intrusion of corrosive media, maintaining long-term structural stability and performance even in harsh corrosive environments. Grace Solar optimizes the wind resistance performance of the mounting system through wind tunnel simulations and structural calculations. By reinforcing joints and improving force distribution, the system can reliably withstand strong wind loads, ensuring the safe operation of power plants even in adverse weather conditions. Considering the soft ground and high groundwater levels in coastal areas, Grace Solar provides foundation solutions and construction methods tailored to the site, ensuring the stability of the mounting system even under complex geological conditions. Additionally, the use of lightweight aluminum materials and modular design significantly enhances construction efficiency and adaptability in coastal environments.

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.
