Quzhou, Dec. 3, 2024 - DAS Solar’s fishery complementary PV project in Hainan has passed TÜV Rheinland's rigorous onsite inspection, excelling in appearance and EL-induced crack tests. The project, which utilizes the company's flexible mounting systems, faced the level-17 super typhoon Yagi and proved its outstanding reliability in extreme weather conditions, ensuring the project's long-term stability and returns.
As solar projects evolve, "PV +" applications are becoming increasingly popular. This trend has led to diversified project setups, adding complexity to mounting system selection. DAS Solar's fourth-generation flexible mounting system stands out for its high ground clearance, large span, and superior safety, positioning it as a leader in differentiated market competition. The system has demonstrated its brilliance across various scenarios, including fishery, agriculture, forestry, and desert control applications.
The 70MW fishery complementary PV project is the first in Hainan to adopt a flexible mounting system for a fishery PV hybrid setup. DAS Solar not only provided the mounting system but also offered comprehensive services of design, construction and installation. The system has already proven its resilience by enduring multiple extreme weather conditions, including the super typhoon Yagi in September 2024. The system's performance under harsh environments demonstrates its durability and solid safety features.
DAS Solar's flexible mounting system features a space cable net structure. The system uses pre-stressed tension in the east-west direction to control mid-span deflection, while the north-south direction employs a stable cable system to strengthen the structure. This unique design improves torsional stiffness and provides effective damping, mitigating the impact of wind-induced vibrations on the modules. In addition, the system has passed rigorous wind tunnel tests conducted by Nanjing University of Aeronautics and Astronautics, showing exceptional stability under wind speeds of up to 46 m/s, equivalent to a level-14 typhoon.
The flexible mounting system is engineered to handle a variety of external loads, including the weight of modules, wind load, snow load, and temperature variations, with wind load being the most significant factor. DAS Solar's system features a mechanical locking design to prevent bolt loosening caused by wind-induced vibrations, safeguarding against potential micro-cracking. With pre-stressed design and structural optimization, the system controls out-of-plane deformation, thus reducing the risk of module damage. Unlike traditional rigid mounts, DAS Solar's flexible system uses elastic deformation to absorb and buffer external loads, ensuring superior safety under extreme weather conditions. This system design plays a critical role in preventing module cracks and improving their service life and energy generation efficiency.
Moving forward, DAS Solar remains dedicated to reinforcing its competitive edge by focusing on market demand. Through innovative product design and high-quality manufacturing, the company will continue to provide "PV+" solutions for various sectors, facilitating sustainable economic growth and contributing to the global shared target of carbon neutrality.
