Abstract: Methods and systems for transporting solar tracker components are disclosed herein. An autonomous mobile carrier unit includes a controller, a motive source coupled to the controller, one or more wheels coupled to the motive source to autonomously move the autonomous mobile carrier unit, and a conveyor mechanism coupled to the controller. The conveyor mechanism is configured to move one or more solar tracker components along the conveyor mechanism, relative to the one or more wheels.

Abstract: A solar tracker includes a ground pier including a first leg and a second leg, each of the first leg and the second leg configured to be partially embedded in a ground surface, and a solar module supported by the ground pier. At least one of the first leg or the second leg comprises a bimetallic strip.

Abstract: Methods and systems for controlling a solar tracker system include solar tracker systems including a controller configured for determining a sun elevation angle, determining a solar array backtracking angle based on the sun elevation angle, determining a torque tube twist angle relative to the solar array backtracking angle, determining an offset angle for the solar tracker based on the torque tube twist angle relative to the solar array backtracking angle, and in response to determining the offset angle for the solar tracker, controlling the solar tracker to rotate a torque tube of a solar array to the offset angle.

Abstract: A modular audio processing apparatus that joins channels together such that four digital audio channels can be transmitted over a single connection, where the apparatus includes housing around a plurality of analog inputs, a plurality of analog outputs, a plurality of digital inputs, and a plurality of digital outputs.
