Arctech, a provider of solar tracking, racking and building-integrated photovoltaic solutions, launched its latest single-axis solar tracking system, SkyLine II, a one-in-portrait (1P) tracker.
SkyLine II features both an enlarged tracker chord and length to address stability challenges of large format modules.
“With a pentagonal torque tube and a synchronous multi-point drive mechanism, Skyline II is one of the few truly rigid 1P trackers in the industry. The design not only strengthens SkyLine II by equipping it with greater bending and torsion capabilities, but also ensures the highest stability at all tracking tilts,” said Bruce Wang, Arctech chief technology officer at the product launch ceremony. “Due to its design, SkyLine II uses the fewest posts per megawatt in the industry (180 posts/MW), reducing engineering, procurement and construction costs by approximately 2%.”
The pentagonal coupling tube gives SkyLine II greater bending and torsion ranges.
The synchronous multi-point drive mechanism stiffens the tracker to the point of engaging 0° windstow mode to maintain safe wind pressure levels on the new large format modules and prevent tearing and delamination. Skyline II activates windstows at 22 m/second.
Skyline II can adapt to different numbers of strings per tracker by adding or removing poles and disks. This design choice was made to adapt the system to different terrains.
“For years, Arctech has been committed to contributing to a more innovative and efficient PV industry. The latest examples were the new SkyLine II tracker, our own tracker-specific wind tunnel testing facility, and so on. Arctech is also an active player in setting international and domestic standards for tracker-related products, working with partners to make this God-given energy affordable for the world.” said Guy Rong, president of Global Business at Arctech.
