  • Antaisolar’s AT-Spark solar tracker features a new multi-slew drive system and an octagonal torque tube that improves stiffness by 40% and strength by 50% while reducing material costs by 30% 

  • Its patented dual-spherical bearing design accelerates installation by ~25% and adapts automatically to uneven terrain 

  • The SmartTrail intelligent control system optimizes tracker angles, enhances energy yield, and provides multi-weather protection modes 

Antaisolar has unveiled its next-generation AT-Spark intelligent solar tracking system, designed to improve performance, efficiency, and lifecycle value for utility-scale photovoltaic (PV) plants. The platform was introduced during the company’s global online launch event, Spark ON. 

AT-Spark is promoted as an advanced tracker solution that combines structural upgrades, smart controls, and comprehensive services aimed at lowering the levelized cost of energy (LCOE). 

According to the company, a core feature of AT-Spark is its multi-slew drive system, paired with its self-developed octagonal torque tube. It states that this design improves structural stiffness by 40% and overall strength by 50%, helping the tracker withstand diverse site conditions while cutting steel consumption by 30%. 

The system also supports a 143-meter tracker span, reducing the number of piles required by an estimated 20%. With 145 mm and 170 mm shaft options, AT-Spark is engineered for various terrains and wind environments. 

AT-Spark features a newly patented dual-spherical bearing, which the company says can automatically adjust to varying slopes and terrain irregularities. It claims that the self-adjusting bearing reduces installation complexity and increases efficiency by around 25%, compared to conventional designs that require precise manual alignment. 

It also features a modular quick-install housing, which further shortens construction time and lowers labor requirements, an important factor for large-scale sites with tight deployment schedules. 

The tracker integrates Antaisolar’s SmartTrail intelligent control system, which uses advanced algorithms to determine optimal module angles for direct, diffuse, and reflected irradiance. This contributes to higher overall system energy generation. 

 SmartTrail also includes 4 intelligent protection modes that automatically respond to extreme weather events such as high winds, snow loads, flooding, and hail. With IP65/IK07 protection standards and industrial-grade components, the system is engineered for long-term field durability, says Antaisolar. 

Monitoring and control are supported by a mobile app, SCADA Station, and SCADA Remote, providing real-time data, remote operations, and intelligent O&M management. 

Beyond the hardware, Antaisolar positions AT-Spark as a full lifecycle solution, covering system design, manufacturing, delivery, installation, and after-sales support. The company offers a global supply chain, rapid spare-part dispatch (2448 hours), and localized technical service teams to support long-term operational reliability.
