Abstract: A variety of techniques may be employed alone or in various combinations, to track alignment of solar collectors with movement of the sun. One approach utilizes two or more piles offset from a single axis of tracking rotation, to provide foundational support. By allocating support between multiple foundational piles, such embodiments reduce the size of any individual pile needed to withstand accumulated torque from sources such as wind. Another approach utilizes an attachment feature to attach a panel to an underlying support arm. The attachment feature may be glued to a bottom surface of a collector panel, and locked into place on the support arm using sliders. Another approach focuses upon the arm structure itself, and the manner of its attachment to a torque tube of a single-axis tracker. Other approaches relate to techniques for stowing solar trackers, and field layout designs for solar trackers.
