The dual post design is ideal for tracker sites with challenging soils or ground frost considerations. Traditional piles rely on skin friction for pull out values and deep embedment depths to combat frost heave. With a dual post system, the loads are spread out differently allowing for lighter weight material, less surface area and shallower depths. The tracker connection is adaptable for all major tracker manufacturers, ensuring compatibility.
