Alion Mounting System (AMS)

AMS 2.8 deployed at a project in Jalisco, Mexico

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

  • The system is ballasted to ease construction for sites with difficult geotechnical conditions, e.g. very hard or very soft ground
  • The track ballast enables the Alion SPOT cleaning system that delivers low-cost, cleaning with water-carrying automated vehicles
  • Panels arrive at site with racking attached onto their backs in a folded position. They are quickly unfolded and installed for fast and simple construction.

 Construction Method

The AMS construction method is designed to simplify logistics and to make construction fast and simple.

Construction Steps:

  • A slip-form paver is used to make the concrete track ballast. These machines are used all around the world to make curbs, highway barriers, and other similar concrete structures. Unreinforced concrete is used.
  • Metal leg structures are fastened to the backs of the solar panels with adhesive at the solar panel factory. Panels are shipped to site with most of the racking components attached in a folded position.
  • At the project site, workers unfold the legs on the back of each panel, attach a cross brace, and place them in position on the track. A second brace is attached between panels.
  • The metal feet are fastened to the concrete track with construction epoxy.

Alion’s AMS technology is covered in U.S. patent #9,657,967 and by corresponding foreign patents in multiple countries.

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.
