The Chinese company says its AT spark has a length of up to 143 meters and a rotation range of 60°. A maximum of 120 solar panels can be installed.
Chinese PV mounting system manufacturer Antaisolar has launched a new horizontal single-axis solar tracking system.
The tracker, called AT-Spark, is designed for utility-scale solar power plants and has a length of up to 143 meters. Each tracker can accommodate between 90 and 120 solar panels, depending on their size.
“AT-Spark features a multi-slew drive system with an octagonal torsion tube, increasing stiffness by 40% and strength by 50%, while reducing material costs by 30%,” the company said in a statement. “With 145mm and 170mm axle options, AT-Spark adapts to a variety of terrain and wind conditions. The newly patented double-spherical bearing automatically adjusts to the slopes of the terrain, minimizing the need for manual alignment.”
The tracker offers a rotation range of approximately 60° with an accuracy of 2°. It can tolerate north-south slopes of up to 15% and requires foundations such as piles, pre-drilling, concrete piles or polyhybrid composite (PHC).
The system is designed to withstand wind speeds of up to 70 m/s and temperatures from -30°C to 60°C. Each tracker uses a single controller that controls a synchronous multi-point slew drive, powered by a 24 V DC motor.
“Equipped with the SmartTrail control system, AT-Spark integrates Antaisolar’s advanced tracking algorithm to optimize module angles based on direct, diffuse and reflected radiation, maximizing energy yield,” the company added. “After passing 42 extreme tests, it offers IP65/IK07 protection, industrial-grade chips and encrypted data communication. The mobile app, SCADA Station and SCADA Remote enable real-time monitoring, remote control and intelligent O&M management.”
