#### HSATS
**HSATS**
**Description:** Horizontal Single-Axis Tracking Structure. A central pole supports a rotating frame that can track the sun along one axis.
**Typical use case:** Tracking installations where panels rotate around a horizontal axis.
**How it works:**
- A single central pole is placed at the base height.
- Purlins run along X, rafters run along Y — together they form a flat frame that can be tilted.
