SZGZ-X Dual-Axis Solar Tracker · Interactive 3D Demo
Eight scenes explain one eight-module dual-axis tracking power station: 8 × 620 W PV modules (2.3 × 1.1 m) with a nominal capacity of 4.96 kWp, dual-motor azimuth and tilt drive, 176 original CAD parts in 9 assembly groups, an SDE7A slew drive, eight native purlins and horizontal / tilt limit interlocks, closing on an exploded view of the whole station.
01 Overview
SZGZ-X
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 Motion
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 Tilt Output
Tilt Output
The tilt motor turns the array about its native horizontal axis through the output plate and the round-shaft frame; eight native purlins and four angle beams carry the module load back to the tilt axis, with the travel range held by the tilt limit.

05 Limits & Interlocks
Limits & Interlocks
One horizontal and one tilt limit bracket with two trigger paddles each, plus five M8 limit switches: the array stops when it reaches a travel boundary, and the azimuth and tilt ranges are held by the mechanism itself.

08 Exploded View
Structure, exploded
Nine factory groups stack up above the load-bearing column: the column-cap mount with its level stops, the dual-axis drive with its limit sensors, the tilt output coupling, the round-tube frame with its M8 locks, the four corner beams, the eight purlins, then the eight modules. The control box lifts off to one side. Every group ships pre-assembled — on site the station bolts together around the column.
