Single-Axis Tracking Structures are advanced solar mounting systems designed to enhance energy capture by precisely following the sun’s movement on a single axis. These structures enable solar panels to pivot east to west throughout the day, increasing energy yield by up to 35% compared to fixed mounts. Built with high-strength galvanized steel and corrosion-resistant finishes, these systems offer durability, adaptability, and optimal performance, making them ideal for utility-scale and commercial solar projects.

Introduction to Single-Axis Tracking Structures
Single-axis trackers rotate solar panels around one axis, generally aligned north-south, allowing panels to follow the sun’s path from east to west. This continuous tracking significantly improves the duration and intensity of sunlight exposure during the day, maximizing electricity generation. Compared to fixed solar mounts, which remain at a static angle, single-axis trackers boost energy output and project profitability while maintaining strong structural resilience against environmental challenges.
Types of Single-Axis Tracking Structures
There are several variations of single-axis tracking systems, each catering to different site conditions and project requirements:
- Horizontal Single-Axis Tracker (HSAT): The most common type, with the axis parallel to the ground. Panels rotate east-west with tilt angles typically up to ±60°, suited for flat or gently sloped terrains.
- Horizontal Tilted Single-Axis Tracker (HTSAT): Similar to HSAT but tilted to match geographic latitude or reduce shading, offering slightly better energy yield.
- Vertical Single-Axis Tracker (VSAT): Rotates on a vertical axis, ideal for extreme latitudes or mountainous regions.
- Vertical-Tilted Single-Axis Tracker (VTSAT): Combines vertical rotation with tilt for optimized energy capture on tricky terrains.
