DAS Solar has launched its fourth-generation flexible mounting system, designed to achieve elevations of up to 9 meters. The framework comprises two span arrangements: a medium span measuring 20 meters and a large span of 40 meters. Constructed on a spatial cable net architecture, the system employs prestressed tension in the east-west orientation to control mid-span deflection, while a robust cable network in the north-south direction fortifies overall structural stability. This groundbreaking configuration enhances torsional stiffness and incorporates efficient damping, effectively reducing the impacts of wind-induced vibrations on photovoltaic panels. Additionally, the system is equipped with a mechanical locking system to prevent bolt loosening triggered by wind-induced movements, significantly mitigating the risk of micro-cracking. The mounting apparatus necessitates only 30 bolts per string, which is notably fewer than rival systems that might use as many as 228 bolts. This advancement contributes to simplifying installation while ensuring prolonged reliability.
