Multiple actuator system for solar tracker

A solar tracking system, comprising:

• a support structure including a pair of transverse beams substantially perpendicular to a longitudinal axis of the solar tracking system;
• a base disposed adjacent the pair of transverse beams and configured to rotatably support the support structure;
• and
• an articulation system configured to articulate the support structure relative to the base, the articulation system comprising:
• a gearbox coupled to a portion of each transverse beam of the pair of transverse beams between the pair of transverse beams;
• an actuator having a first end portion and a second, opposite end portion, wherein the first end portion of the actuator is rotatably coupled to the base and the second end portion of the actuator is coupled to the gearbox;
• and
• a drive shaft operably connected to the gearbox, the drive shaft intersecting the pair of transverse beams, wherein rotation of the drive shaft extends and retracts the actuator to cause the gearbox to rotate about the drive shaft and relative to the pair of transverse beams.

A solar tracking system, comprising:

• a support structure including a first beam extending along a longitudinal axis of the solar tracking system and a pair of transverse beams disposed substantially perpendicular to and affixed to the first beam;
• a base disposed adjacent the pair of transverse beams and configured to rotatably support the support structure;
• and
• an articulation system configured to articulate the support structure relative to the base, the articulation system comprising:
• a gearbox coupled to a portion of each of the pair of transverse beams between the pair of transverse beams;
• an actuator interposed between the gearbox and the base, wherein extension and retraction of the actuator effectuates rotation of the support structure about the base;
• and
• a drive shaft mounted in the support structure, the drive shaft intersecting the pair of transverse beams, and operably coupled to the gearbox such that rotation of the drive shaft effectuates extension and retraction of the actuator to cause the gearbox to rotate about the drive shaft and relative to the pair of transverse beams.
