The system includes a screw anchor foundation component having an embedment end and an opposing driving end. A Y-shaped screw cap sleeves over the driving end of the screw anchor and includes a lower portion and a pair of upper portions extending at reciprocal angles relative to a vertical midline. A pair of truss legs are connected to the respective upper portions of the screw cap and extend upwardly to support the tracker structure. ## Claims ### Claim 1 A truss foundation for supporting a single-axis tracker in an agrivoltaics application comprising: a first screw anchor foundation component having an embedment end and an opposing driving end; a first screw cap having a Y-shape and a lower portion configured to sleeve over the opposing driving end of the first screw anchor foundation component and a pair of upper portions extending away at reciprocal angles with respect to a vertical midline bisecting the first screw cap; and a pair of truss legs extending up and away from respective upper portions of the first screw cap. ### Claim 2 (depends on 1) The truss foundation according to claim 1, wherein each of the pair of truss legs terminates at a truss cap that joins each of the pair of truss legs to a respective adjacent truss leg connected to another screw cap having a Y-shape. ### Claim 3 (depends on 2) The truss foundation according to claim 2, wherein the truss cap comprises a tracker bearing for suspending a tracker torque tube. ### Claim 4 (depends on 1) The truss foundation according to claim 1, wherein each of the pair of truss legs is one leg of a unitary truss leg pair configured to be attached to respective screw caps of adjacent screw anchor foundations. ### Claim 5 (depends on 4) The truss foundation according to claim 4, further comprising a bearing housing comprising a bearing plate having a tracker bearing, the bearing housing configured to attach to the unitary truss leg pair at an approximate middle of a bent portion of the unitary truss leg pair. ### Claim 6 (depends on 1) The truss foundation according to claim 1, further comprising: a second screw anchor foundation component having an embedment end and an opposing driving end; a second screw cap having a Y-shape and having a lower portion configured to sleeve over the opposing driving end of the second screw anchor foundation component and a pair of upper portions extending away at reciprocal angles with respect to a vertical midline bisecting the second screw cap; and a third truss leg extending up and away from one of the pair of upper portions of the second screw cap. ### Claim 7 (depends on 6) The truss foundation according to claim 6, further comprising a fourth truss leg extending up and away from the other of the pair of upper portions of the second screw cap. ### Claim 8 A truss foundation for supporting a single-axis tracker in an agrivoltaics application comprising: i. a first foundation comprising: a. a screw anchor comprising an embedded end and a driving end, the driving end further comprising a driving ring; and b. a screw cap configured to couple to the driving end of the screw anchor, the screw cap comprising a pair of connecting portions extending upwardly away from the screw anchor at reciprocal angles; ii. a second foundation comprising: a. a screw anchor comprising an embedded end and a driving end, the driving end further comprising a driving ring; and b. a screw cap configured to couple to the driving end of the screw anchor, the screw cap comprising a pair of connecting portions extending upwardly away from the screw anchor at reciprocal angles; and iii. a first tracker support spanning between the first and second foundations, the first tracker support comprising: a. a first leg portion coupled to one of the pair of connecting portions of the screw cap of the first foundation; b. a second leg portion coupled to one of the pair of connecting portions of the screw cap of the second foundation; and c. a bent portion connecting distal ends of the first leg portion and the second leg portion. ### Claim 9 (depends on 8) The truss foundation according to claim 8, wherein the first leg portion, the second leg portion, and the bent portion of the first tracker support are formed from a single tube. ### Claim 10 (depends on 9) The truss foundation according to claim 9, further comprising a bearing housing comprising a bearing coupled to the bent portion of the first tracker support, the bearing configured to receive a bearing pin to support a torque tube. ### Claim 11 (depends on 8) The truss foundation according to claim 8, wherein the bent portion comprises a truss cap. ### Claim 12 (depends on 8) The truss foundation according to claim 8, further comprising: iv. a third foundation comprising: a. a screw anchor comprising an embedded end and a driving end, the driving end further comprising a driving ring; and b. a screw cap configured to couple to the driving end of the screw anchor, the screw cap comprising a pair of connecting portions extending upwardly away from the screw anchor at reciprocal angles; and v. a second tracker support spanning between the first and third foundations, the second tracker support comprising: a. a first leg portion coupled to the other of the pair of connecting portions of the screw cap of the first foundation; b. a second leg portion coupled to one of the pair of connecting portions of the screw cap of the third foundation; and c. a bent portion connecting distal ends of the first leg portion and the second leg portion. ### Claim 13 A truss foundation for supporting a single-axis tracker in an agrivoltaics application comprising: a pair of adjacent screw anchor foundation components embedded at opposing angles to one other with respect to plumb; a pair of upper leg sections, each extending a main axis of respective ones of the pair of adjacent screw anchor foundation components; a truss cap configured to join the pair of upper leg sections together, the truss cap having a support post projecting from a middle portion thereof; a first screw cap having a Y-shape and configured to sleeve over the support post; and a pair of elongated leg sections extending up and away from respective upper portions of the first screw cap. ### Claim 14 (depends on 13) The truss foundation according to claim 13, wherein each leg of the pair of elongated leg sections terminates at a second truss cap that joins each of the elongated leg sections with an elongated leg section of an adjacent truss foundation. ### Claim 15 (depends on 14) The truss foundation according to claim 14, wherein the second truss cap comprises a tracker bearing for suspending a tracker torque tube.
