Helical actuator system for solar tracker

A solar tracking system, comprising:

• a solar array;
• a plurality of support beams configured to support the solar array;
• a torque tube coupled to the plurality of support beams;
• a base configured to rotatably support the torque tube;
• and
• an articulation system configured to rotate the torque tube relative to the base, the articulation system comprising:
• a first helical tube coupled to the torque tube;
• a first helical tube support disposed on the base and configured to slidably support the first helical tube;
• and
• a gearbox in mechanical communication with the first helical tube,
• wherein actuation of the gearbox causes the first helical tube and the torque tube attached thereto to translate along their longitudinal axes within the first helical tube support, and the first helical tube support is configured to rotate the first helical tube and the torque tube attached thereto as the first helical tube and the torque tube attached thereto are translated along their longitudinal axes therein to cause a corresponding rotation of the solar array.
