A solar collector array is formed of multiple parallel rows of solar panels, each said row being made of one or more building blocks with an east-west oriented torsion tube defining an east-west axis for the row, an array of flat generally rectangular solar panels, and a set of panel rails and rail

A solar collector array is formed of multiple parallel rows of solar panels, each said row being made of one or more building blocks with an east-west oriented torsion tube defining an east-west axis for the row, an array of flat generally rectangular solar panels, and a set of panel rails and rail claims attaching the panels onto the torsion tube. A row of piers aligned on the east-west axis each have a footing that is supported in the earth, and a pier cap affixed onto a top end of the pier. The pier cap holds the torsion tube non-rotationally such that the torsion tube and panels are held at a preset elevation angle. The torsion tube may serve as a conduit for power conductors from the panels.
