As land resources tighten and solar deployment expands into more complex terrains and harsher climates, the need for greater system reliability and safety in PV installations has never been more critical. DAS Solar's flexible mounting system addresses these evolving challenges with innovative structural design, rigorous performance testing, and extensive field validation, establishing a new industry standard for adaptable, high-reliability solar support systems.
Reliable in Structure: Space Cable System for Enhanced Stability
DAS Solar's flexible mounting system replaces traditional purlins with pre-tensioned steel cables. Two pre-stressed cables run east-west to bear load, while a tension-stabilized structure runs north-south, forming a robust spatial cable mesh that strengthens the array as an integrated whole. This unique system significantly reduces wind-induced vibrations and dynamic structural responses, enabling strong resistance against high wind loads and heavy snowfall. It also helps mitigate issues such as microcracks and structural fatigue, ensuring long-term structural integrity and operational stability under extreme weather conditions.
The suspended support configuration eliminates dependence on rigid, ground-level infrastructure, offering superior adaptability to sandy terrain, hillsides, ponds, and tidal flats. With minimal ground contact and distributed load-bearing, this design reduces civil works complexity and cost while preserving the natural environment—delivering optimal land utilization and investment value.
Reliable in Field Performance: Validated Performance in Harsh Conditions
Beyond engineering design, DAS Solar's flexible mounting system has undergone comprehensive laboratory and real-world testing. In wind tunnel tests at Nanjing University of Aeronautics and Astronautics, the system demonstrated a vibration onset threshold exceeding 46 m/s. In Xinjiang's high-wind zone, it withstood alternating temperatures of ±40°C and level-17 typhoons with no component failure or hidden cracks.
The system's field performance has been further validated at the Longhu fishery complementary PV project in Hainan, where it has withstood multiple typhoons—including Super Typhoon Yagi—without damage. TÜV Rheinland confirmed the modules installed on the system showed no degradation in appearance or electroluminescence (EL) performance, underscoring its reliability in high humidity and saline environments.
Reliable in Engineering: Enhanced through Design and Installation
The system's long-term reliability is further supported by meticulous mechanical engineering. Key joints use anti-loosening mechanical interlocks to prevent bolt loosening due to vibration, eliminating micro-movement wear and the risk of hidden cracks. Pre-tensioned cable systems offer increased flexibility and buffering capacity, improving safety margins under dynamic loads. These features significantly enhance system durability and protect modules over time.
In addition, DAS Solar's high degree of pre-assembly and its slide-in module mounting method increase installation efficiency by over 20%, reducing on-site labor costs and construction timelines. This streamlined installation process also minimizes environmental disruption and lowers the carbon footprint of construction.
Reliable in Application: Enabling Multi-scenario Deployment
DAS Solar's flexible mounting system has proven its versatility across diverse applications. In Shaanxi, it supports solar-powered sand control efforts while enabling under-array vegetation growth for dual ecological and energy gains. Its high-clearance design enables integration with agriculture and aquaculture, supporting sustainable land use without compromising green energy output.
In Shanxi, DAS Solar provided a customized solution to accommodate the region's rugged loess hills. This not only increased project capacity and reduced investment costs, but also made efficient use of challenging terrain. In Yunnan, the system supports a "herbal medicine + PV" model, integrating solar generation with under-array cultivation of medicinal herbs. This dual-use strategy optimizes agricultural structure while improving land utilization and regional economic returns.
Through a combination of technical innovation, system-wide validation, and versatile application, DAS Solar's flexible mounting system redefines safety and reliability standards for solar support structures. Its track record of zero failures across independent testing and major projects highlights its readiness to support PV deployment in complex environments and hybrid-use scenarios. Looking ahead, DAS Solar remains committed to advancing product performance and quality, driving solar system development toward greater safety, resilience, and intelligence.
