Arctech launches SkyWings, a dual-row single-axis solar tracker

Arctech, a global provider of tracking, racking, and buildings integrated photovoltaics (BIPV), announced it has launched its latest solar tracking solution, called SkyWings. The tracker is a dual-row tracker designed with bidirectional slew drives and a multi-point drive mechanism.

The product combines the advantages of dual row solar trackers and is compatible with undulating terrain with high rigidity enabled by a multi-point drive design. The patented bidirectional slew drives allow two rows to move in synchronicity.

The undulation tolerance of adjacent rows has increased to 15% in both East/West and North/South directions. The modular design allows flexibility in plant layout design, accommodating more PV modules than conventional trackers in the same conditions, said Arctech.

SkyWings incorporates a multi-point drive mechanism and specially designed torque tube-the patented triple D torque tube, allowing for stowing in a horizontal position with the highest stability.

The rack allows modules to be stowed flat, which prevents cracking and delamination, particularly in newer large-format modules. SkyWings only starts stowing at 22m/s, which generates up to 2% more energy yield per year, leading to a lower levelized cost of energy.

The post span can be extended by 10 meters, which the company said can bring down installation costs by up to 20% and the entire engineering, procurement, and construction expenditure by up to 2%, compared to projects utilizing traditional 1P trackers.

The trackers are controlled by second-generation AI-assisted algorithms, calculating optimum tilt in various weather conditions and topographies. Arctech said the real-time shading avoidance can boost production by 8%.

In desert environments, the SkyWing tracker can be paired with Artech’s cleaning robot, SkyWe.
