Alion Storm Tracker
The Alion Storm Tracker is a ballasted single-axis tracker with optional automated cleaning robots for soiling & albedo control. Fully ballasted for sites with challenging geotechnical conditions, Accommodates sites with uneven slopes with its articulated drive tube, Uses substantially less steel than leading torque tube trackers, Uses 30% more panels per drive than typical torque tube systems, Enables Alion’s automated SPOT panel cleaning system (see information for SPOT), Compatible with framed or frameless modules, including thin film, and bifacial panels, High wind zone capable.
The patent pending Alion Storm Tracker uses a continuous, jointed concrete track that supports a distributed structure for inherently high stiffness. A drive tube transmits torque from a row-based motor and slew drive to a series of gears that rotate each tracker section. The patent pending Storm Lock mechanism locks the tracker in a stow position, enabling a lower-cost drive and structure. Major parts are factory pre-assembled to reduce field labor and field construction time.
Performance
Single-axis rotation greater than +/- 60°
Ballasted system can traverse up to 15% slope
A single drive can operate up to 145 72-cell modules
Strong A-Frame and Arc Structure
Storm-Lock disengages drive system during high-wind events. Enables longer strings for 10% CAPEX savings.
