Reinforced pile for solar foundations

A method of installing a solar tracking system, comprising:

• determining if a beam of the solar tracking system needs reinforcement, the beam including a pair of spaced apart flanges and a web interposed between each of the pair of spaced apart flanges, wherein each of the pair of spaced apart flanges defines a flange width extending between a first flange side that is offset from the web and a second flange side that is offset from the web, wherein at least one of the pair of flanges including a plurality of bores offset from the web;
• if it is determined that the beam does not need reinforcement, drive the beam into earth;
• if it is determined that the beam needs reinforcement, identifying a portion of the beam that needs to be reinforced;
• coupling a first reinforcement plate to the identified portion of the beam to form a reinforced beam, wherein the first reinforcement plate defines a plate thickness extending between a plate top surface of the first reinforcement plate and a plate bottom surface of the first reinforcement plate and in a direction transverse to the plate width, wherein the first reinforcement plate is coupled to the one of the pair of flanges to extend the plate thickness out from the one of the pair of flanges to define a greatest thickness of the beam at the location of the first reinforcement plate without extending the plate width past the flange width and without increasing a thickness of the web;
• driving the reinforced beam into the earth;
• and
• after driving the reinforced beam into earth, selectively coupling a bearing housing assembly to a portion of the reinforced beam.
