Asun offers a dual-axis tracker with independent east-west and north-south movement, differing from conventional 360° DAT systems
The design supports up to 30 modules per row and integrates bifacial-focused spacing to enhance rear-side gain
The system features actuator-based drives, 1,500 V compatibility, and wind tolerance up to 170 km/h
The dual-axis tracker (DAT) segment in the TaiyangNews Market Survey on Solar Trackers 2026 remains limited in terms of supplier participation. Asun is among the companies featured in this segment of this year’s survey, with its 2 Axis Tracker offering an alternative approach to conventional DAT configurations.
Asun’s product may not fully meet the classical definition of a DAT, as the tracker table does not rotate 360° to track the sun all through the day and year. However, the Asun 2 Axis Tracker facilitates full dual-axis movement with independent east-west and north-south adjustment. The setup looks much similar to an HSAT, while the modules move East-West and the table moves North-South. This 2023 model supports up to 30 modules per row, and the whole system measures 45 × 2.6 × 1.5 m with an approximate weight of 980 kg. According to company data, the design enables daily east-west tracking combined with a north-south tilt range of -10° to 50°, allowing the system to maintain optimal module incidence angles throughout the year. This configuration is aimed at maximizing energy yield, particularly in regions with high seasonal variation in sun path. The design is also pro-bifacial; it incorporates panel-to-panel spacing intended to enhance ground-reflected albedo capture from both the underside and reverse of adjacent modules. The tracker has a ground-coverage ratio of 52% and is supplied with SHS foundations. Asun reports that this dual-axis tracking technology has patents granted in India, the USA, Canada, the UK, and the EU.
The tracker supports all commercial module formats, operates at 1,500 V DC, and is compatible with robotic module-cleaning solutions. Similar to the company’s single-axis tracker discussed above, this product also integrates linear-actuator drive systems with ±2° accuracy, brushed DC permanent-magnet motors, and LoRaWAN or RS-485 communication options. These trackers are designed for wind stowing at 60 km/h, can tolerate wind speeds of up to 170 km/h, and maintain a storm-safety position of 0°. Asun offers a 10-year warranty on the structure and a 3-year warranty on the motor and electronics. The delivery time for both systems is listed as 6 months, and the distribution area covers India and Nepal.
