Abstract: A bearing for single-axis solar tracking system includes a journal with a tube portion connected to a pair of flanges that are configured as a thrust-stop. The bearing further includes a race removably connected to the journal.

Abstract: One embodiment provides an apparatus for a single axis tracker that includes a first strap component formed into a first portion of a bearing race. A second strap component is formed into a second portion of the bearing race. The first portion of the bearing race and the second portion of the bearing race removably interleave to hold a torque tube.

Abstract: A solar panel assembly includes a first torque tube and a mounting rail including a cutout portion that attaches to the first torque tube. The mounting rail including an upper portion configured for mounting multiple solar panels. The mounting rail establishes and maintains an electrical ground path from the solar panel assembly to the first torque tube.

Abstract: A system includes a coupler-journal including a central body portion and a coupling portion. The coupler-journal is configured for attaching with a first torque tube and a second torque tube. A bearing is configured for placement around the central body portion.

Abstract: One embodiment provides a drive system that includes a drive device with at least one drum for spooling at least one wire rope. A mounting device is connected to the drive device and a single-axis tracker. At least one partial pulley is connected to a torque tube. The at least one partial pulley is configured to accept the at least one wire rope and to transfer leveraged drive forces to the torque tube.

Abstract: One embodiment includes a device for solar tracker systems. The device includes a first purlin including a first mating surface configured for frictional attachment to a first side of a torque tube. The first purlin further including a first linear shaped top surface configured for mounting a first solar module. A second purlin includes a second mating surface configured for frictional attachment to a second side of the torque tube. The second purlin further including a second linear shaped top surface configured for mounting a second solar module. The first purlin and the second purlin connect to one another with a fastening clamp that is configured for holding the first purlin and the second purlin against the torque tube.

Abstract: A journal-coupler includes a first portion including a first pair of flanges and a first coupler portion and a second portion that is removably connected to the first portion. The second portion includes a second pair of flanges and a second coupler portion. The first coupler portion and the second coupler portion combine to form an enclosed torque tube portion.
