Performance is defined by reliability & maximum ROI
ROBUST & RELIABLE
Strategically designed for strength and long-term reliability, the high density, low profile DuraTrack™ tracking system is simple and robust, certain to simplify the deployment process and reduce system lifetime costs.
The tracker structure contains PV modules mounted on a tracker support column framework aligned in a north-south row configuration. The tracker rotates PV modules about the horizontal axis in an east to west motion, following the sun throughout the day.
Tracker range of motion is ±45° about the north-south horizontal axis. Backtracking (shade avoidance) is employed to eliminate shading and maximize production in the early morning and late afternoon.
DRIVE & CONTROL ARCHITECTURE
One A/C drive motor drives 350-650 kW of PV modules. Individual motor controllers are capable of operating independently, and a GPS-enabled central control unit collects individual controller data, and provides supervisory control.
Multiple DuraTrack tracker rows are connected by a rotary drive shaft and driven by a single industrial 1.5-3 HP, 3-phase A/C motor. The number of tracker rows is determined by system size and field layout requirements.
