Abstract
A one-piece truss adapter for supporting single-axis trackers with truss foundations. A upside-down Y-shaped structure has bearing support portion and an opposing pair of legs with an angularly adjustable connector for securely joining the one-piece adapter to a pair of driven screw anchors at different angular orientations. Each leg terminates in a connector that is received in a socket integral to a driving coupler at the head of each screw anchor. A retaining nut may hold the connector in place to complete the angularly adjustable assembly.

A foundation system for single-axis trackers comprising:
- a pair of elongated screw anchors, each screw anchor of the pair having a first end with an external thread and an opposing second end, with a driving coupler;
- and
- an upside-down Y-shaped truss adapter, the upside-down Y-shaped truss adapter having a pair of angled legs at a lower end and a bearing support portion at an opposing upper end, wherein one of the pair of angled legs is received in one of the driving couplers and the bearing support portion comprises a pair of opposing planar mounting surfaces for receiving a bearing assembly.
An assembly comprising:
- a pair of elongated foundation members, each member of the pair having an externally threaded end and an opposing driving end, the driving end terminating in a driving coupler;
- a truss adapter having an upper bearing support portion and a pair of lower leg portions, each of lower leg portions terminating in a connector adapted to mate with one of the driving couplers;
- and
- a tracker bearing assembly attached to the bearing support portion and providing a bearing for receiving a rotating member.
