Abstract
A solar energy system includes a photovoltaic (PV) assembly and a drive system. The PV assembly comprises a support subassembly and an array of PV panels pivotable therewith about a longitudinal axis of the PV assembly. The drive system comprises a motor assembly comprising an electric motor and a gearing arrangement, and a pivot wheel comprising a hoop-portion and joined to the PV assembly. The hoop portion includes an outer circumferential channel, and two opposing catches defining a maximum pivot range. A chain resides partly within the circumferential channel, is engaged with the two opposing catches, and is also in geared communication with the motor assembly such that the motor is operable to rotate the pivot wheel. In some embodiments, the opposing catches define a maximum pivot range through an arc of more than π radians and less than 2π radians.
