Alion Energy
The Most Power from PV.
A 1P tracker that takes the ground as it is — clay, cobble, slope, water — and holds in the storm.

The site is the product
Most trackers assume you can drive piles. That is why they sit on farms.
Rockless, arable soil is chosen because a driven steel pile goes in. Refuse rates stay low. The field that grew food becomes the PV plant. That is the quiet food-versus-energy fight: not ideology — geotech.
Our work is to take that fight off the farm. Make brownfields and “disqualifying” ground — cobble, clay, rock, standing water — cheap enough to build on, and the arable acre stays in food. The unique offer is not “no piles.” It is full foundation flexibility: match the foundation to the site, including where piles refuse.
Fifteen granted patents on that path: slipform ballast, A-frame support, and the joint to concrete.
Mechanism
A tracker for all lands
Same mechanics across every foundation: mechanicals, drives and controls. The A-frame sits on several foundations — Split Rail, Full Reflector, precast / CIP. The driven-post version does not — same mechanicals, drives and controls, no A-frame. Cable earth anchors are a separate 2027 NPI foundation.

≤20 kg
≤ 44 lb · every steel part
One person can lift it. Less crane time. Faster assembly on the row. Future proof for humanoid robotics.
Drive more modules
1.3×
modules per drive · 120 × 700 Wp / 3″ slew
More modules per drive than a typical 1.5 m torque-tube SAT. Powerful gearing for heavier PV modules.
Run up and down hills
We pioneered terrain following and inspired others.

Mountainside rocky soils implementation
Same mechanics · foundation matched to the site
Same mechanicals, drives and controls. Match the foundation to the site.
Corrosive volcanic silt
Foundation
Split Rail Foundation
Continuous slipform ballast. Match the foundation to clay, cobble, slope, and standing water. 0 piles.
Subsurface rock
Foundation
Full Reflector Foundation
Slipformed ballast you can see — albedo and soiling control. Same A-frame as Split Rail.
Active clays
Foundation
Precast / Cast-in-Place
Precast or CIP concrete. Same A-frame as Split Rail. Use when slipform is not the path for that land.
Basalt flows
When a driven pile refuses
Micropile
Small-diameter piles, drilled and grouted. No A-frame — same mechanicals, drives and controls as the rest of the plant. For rock, cobble, and hardpan — ground that will not take a driven post.
Corrosive cotton soils
When the site takes a post
Steel Pile
Single pile when the ground will take a driven or drilled post. No A-frame — same mechanicals, drives and controls as the ballast plant.
Remote islands / off-grid
2027 NPI
Cable earth anchors
Cable anchors when the site is too remote to ship in concrete or steel piles. Separate 2027 NPI foundation.
Install and leave the land
Slipform the foundation. Lift the rail when the plant comes down.
This pour is Split Rail on volcanic silt in a national park with buried archaeological resources. Single piles and micropiles were not allowed. At end of life the foundation comes out as a rail, not a corroded pile field. Recycled ballast can be LEED material and sold as aggregate.
