Solar tracking system with a mechanical drive mechanism using a flexible transmission shaft

Abstract

A solar tracking system with torsion tubes having solar panels (modules) mounted thereon. Columns support the system and have bearings for rotation of the torsion tubes. A flexible transmission shaft is connected at one end to a mechanical drive mechanism for rotating the torsion tubes and thereby rotating at least an individual row of modules to follow the sun's diurnal motion. The torsion tubes can be rotated in an opposite direction, or backtrack, to prevent shadowing from one individual row of modules to another. The flexible transmission shaft is connected to a single motor at its other end and is constructed of flexible materials to compensate for misalignment due to uneven terrain or staggered row of module configuration. Dampers are also employed and affixed to the row of modules to decouple wind forces imposed on the row of modules.
