  • Antaisolar lists 3 HSAT products, including 2 new entries and 1 updated model, while withdrawing 1 listed previously

  • The new AT-Spark targets high-wind applications, while TAI-Universal marks the company’s 2P offering in the survey

  • Common features across the portfolio include ±60° tracking, multi-protocol communication, and expanded sensor integration

The 4th TaiyangNews Market Survey on Solar Trackers showcases 32 products from 17 suppliers, including most market leaders in this segment.

While several tracker variants exist, HSAT and DAT are the 2 mainstream configurations, with HSAT dominating commercial deployments. Of the 17 companies listed, the majority offer HSAT products, while only 3 companies provide dual-axis tracker solutions. One of these solutions does not fit the classical definition of a full dual-axis tracker, but is included because it enables sun tracking throughout the day and supports seasonal adjustment.

Antaisolar is the first in the list, providing data for 3 products, 1 more than the last survey. Of the 3 listed, 2 are new models, while 1 was also featured in the previous edition, but is now promoted with updated specifications. The company has also withdrawn 1 model, TAI-Space, from the listing. AT-Spark is a new product introduced in 2025, while the TAI-Universal, although a 2020 model, features for the first time. Albeit with a few updates, the company continues to feature its legacy product, TAI-Simple. All 3 systems follow Antaisolar’s HSAT architecture and share many common elements, including a tracking range of ±60°, compatibility with all commercial framed modules, support for 1,000/1,500 V strings, and the company’s upgraded communication platform based on Zigbee wireless mesh networking, Ethernet, and RS485. AT-Spark is Antaisolar’s newest tracker, designed for high-wind applications. It is a 1P system with a total row length of 143 m and supports 90 to 120 modules, depending on their format. The system is equipped with a synchronous multi-point slew drive powered by a 24 V DC motor with ±2° accuracy. According to the company's data, AT-Spark has a wind-load rating of up to 70 m/s under ASCE 7-10, making it the strongest product in the company’s current catalog. The stowing angle is 0°, and structural enhancements such as larger post spacing and reinforced mechanical stability distinguish it from other models. The tracker is fully compatible with robotic cleaning systems and integrates a complete sensor suite, including wind, snow, radiation, flood, and rainwater detection.

TAI-Universal, while new to the survey, is not new to the market. This 2020 model is Antaisolar’s dedicated 2P solution. The tracker measures 70 × 5 × 2.5 m and supports an array height of 4.7 m, accommodating 90 to 120 modules. The system uses a synchronous multi-point slew drive and maintains a driven line gap of 100 mm, a feature that supports bifacial design. It is rated for wind speeds of up to 55 m/s, with a recommended stowing position of 5°. Similar to AT-Spark, it is governed by astronomical and intelligent tracking algorithms and is offered with the company’s updated communication and sensor packages.

As mentioned above, TAI-Simple features several updates, while its core structure remains unchanged from earlier editions. It carries forward design elements such as a 95 m length, ±60° tracking angle, and SPA-based control. Even the wind-speed tolerance remains 198 km/h with a 7-10-second gust, and the recommended stowing position is also unchanged at 30°. Among the upgrades, the array height has increased to 2.6 m from 1.5 m, the bifacial gap is now specified as greater than 70 mm, and the spec for the modules has been broadened to ‘all commercial modules’. The communication system is upgraded to the same multi-protocol platform used across the new lineup, and the sensor set is expanded to include measurements of radiation, flood, and rainwater, in addition to wind and snow.

All Antaisolar trackers listed in the 2025 survey follow a unified warranty structure. Each of the company’s models is supplied with a 10-year structural warranty and 5-year coverage for both the motor and the electronics, excluding batteries.
