TG-24 Dual-Axis Solar Tracker · Interactive 3D Demo
Eight scenes explain one dual-axis solar tracker: 67.6 m² of light-collecting area per unit, a 6.91 × 10.00 m sail, a 3.02 m column, ±180° azimuth slew and 0–70° tilt travel, 632 parts, 8 major assemblies and 37 interlocking constraints, closing on an exploded view of the whole machine.
01 Overview
TG-24
Our in-house solar tracking racking is different from fixed racks and single-axis trackers. It adjusts azimuth and tilt at the same time, keeping the modules at the best angle to the sun all day. Load-bearing structure, dual-axis drive, position feedback, control strategy, safety protection and cloud O&M make up six parts that work together as one complete solar tracking system.

02 Dual-Axis Tracking
Azimuth Slew + Tilt Actuator
Powered by the SmartTrack™ 3.0 tracking algorithm: astronomical calculation and edge computing work together to stay locked on the sun's path; local irradiance and weather data correct the aim in real time, and tracking continues even under overcast diffuse light, with no grid power needed. Average annual yield is up 30%, and the winter peak gain can exceed 50%.

03 Slew Drive Assembly
Slew Drive Assembly
The slew mechanism ties drive, reduction and bearing support together on the azimuth axis, turning the upper array horizontally to follow the sun's azimuth angle.

04 Dual Actuators
Dual Actuators
Two electric linear actuators apply axial thrust to the tilt mechanism through their hinge points. Dual Hall sensors feed stroke detection and coordinated control, reducing off-centre loads and the risk of abnormal operation.

- Conditional static load
- 50kN
- Stroke

- Electric actuatorStroke 300 ±3 mm
05 Mechanical Dampers
Dampers
8 dampers are distributed across the connections, helping to control transient disturbance and motion oscillation. A velocity-dependent damping force dissipates kinetic energy, softening the dynamic shock transmitted to the load-bearing structure, hinge points and drive train. Together with active drive, limit protection and high-wind strategy they keep the unit running smoothly.

08 Exploded View
Structure, exploded
The machine comes apart into its assembly groups: base column and foundations, azimuth ring, slew drive, tilt sail, module clamps and the PV array separate along the mast, while the two actuators and eight dampers lift off to the sides. Every group ships pre-assembled — on site the whole machine bolts together around the column.
