Alion Energy StormTracker® Single-Axis PV Tracker

Alion Energy redesigned the single axis tracker to deliver a fundamentally lower lifecycle cost st


  • A better structural design substantially reduces steel use versus common torque-tube trackers while improve reliability in wind events
  • A slip-formed ballast enables easy construction on sites with difficult geotechnical conditions
  • The track ballast serves as part of the automated cleaning vehicle system, lowering the cost of panel cleaning and boosting bifacial gains


    Tracker install in Chile;  Design eliminates need to roll heavy equipment to move torque-tubes and provides durable albedo boost for bifacial pv modules




Alion Mounting System Fixed Tilt with integrated structures

The Alion Mounting System uses an unfolding racking structure and slip-formed track ballast for fast field construction of fixed-tilt arrays on difficult sites.

  • Ballasted for easy construction on difficult ground
  • The track ballast enables low-cost, cleaning with water-carrying automated vehicles
  • The AMS is installed quickly and easily because of the unfolding racking system/>


    Fixed-tilt install in Mexico.  

    Very fast install as structure comes pre-attached from the module factory & the legs fold out.  

    Low profile aesthetic and high wind performance on clay.






SPOT Automated Cleaning

Alion Energy offers a robotic solar plant cleaning solution that makes cleaning reliable, low-cost, and easy.

  • The concrete ballast tracks built into the racking enable the autonomous, dry & wet-cleaning robotic vehicle
  • The robots can move row to row to minimize robot count per project using carts or rails

The Most Power from PV

Alion Energy provides the best tracker, kept clean to deliver the most energy and ballasted to perform in the most challenging sites.

Maximize Energy Yield

Reflective, ballasted foundations, paired with automated cleaning solutions, plus a durable, high wind capable tracker design, improve energy yield and protect against performance loss.

Lowest Solar LCOE

Alion Energy builds local, utility scale projects faster and for lower cost, while producing more energy yield than standard pv tracker projects. Generate higher returns with the lowest cost of power in the industry.
