Support structures for solar tracker systems with increased tolerance

A truss foundation comprising:

• a pair of truss legs, each truss leg comprising:
• an elongated anchor having a top end portion and a bottom end portion opposite the top end portion;
• and
• an elongated upper leg comprising a first leg portion and a second leg portion, the first leg portion having a first planar side and the second leg portion having a second planar side, the first planar side positioned adjacent the second planar side and defining a gap therebetween, the first leg portion and the second leg portion configured to couple with the top end portion of the elongated anchor at a second end portion of the elongated upper leg;
• and
• an adapter having a main body and a pair of connecting surfaces projecting away from the main body and spaced apart by an angle in a range of more than 35-degrees up to and including 70-degrees, the adapter configured to couple with a first end portion of each of the elongated upper legs to form an A-frame shaped truss structure.
