Axial introduces AxialTracker SlopeSync, a new dual-row tracker.

Along its main axis of rotation, the new tracker uses cardan joint technology, which permits each torque tube section to have a distinct inclination or slope while preserving the PV modules’ rotational continuity.

In order to “allow adaptability and total synchronization to all terrains, even the most complex ones,” Axial, a Spanish company that specializes in the design, manufacture, and operation of solar trackers for utility-scale PV projects, has introduced the AxialTracker SlopeSync, a new dual-row tracker that incorporates cardan-type joint technology along its main axis of rotation.

With the help of this technology, it is possible for each torque tube section within a single tracker to have a different inclination or slope while still retaining the PV modules’ constant rotation. the tracker’s useful life has been extended by the system’s design, which prevents induced stresses from arising and implies no profile or structural deformation in the process of adapting to the terrain.

“The AxialTracker SlopeSync transforms the solar tracker industry by doing away with the requirement for pillar alignment because it does away with the idea of a straight rotation axis,” . The pillars of a follower may vary in height based on the irregularities of the terrain because each section of the torsion tube between two successive pillars may have a different inclination because of the cardan joints.

Axial’s technical features include “its total synchronization with irregular terrain” and driving tolerances of up to +-400 MM in both directions (N-S and E-W), which are “the highest on the market. Up to 1 m (55º) is the distance to the ground, and it can withstand ground irregularities up to 400 mm (+/-) in between successive pillars.

Because the torque tube connections come pre-assembled and don’t require pillar alignment, installation ratios are improved. Furthermore, it prevents stresses and deformations that could be caused to the structure, and the homokinetic technology permits deviations of up to 30º, allowing for increased route utilization.

Axial is committed to avoiding the occurrence of cyclic over stresses and thus eliminates the risk of undesired long-term phenomena, such as fatigue in the structural profiles or the amplification of deformations that can negatively affect the optimization of tracker production, the company continues. other adaptability systems based on torsion tubes that deform according to orography and impose stresses on the structure, the company adds.

SlopeSync lessens the requirement for earthworks, which lowers expenses and speeds up the completion of projects overall.

From June 19 to 21, Axial will be showcasing the new tracker at Intersolar in Munich at stand A6 .320.
