Methods and devices for assembling a terrestrial solar tracking photovoltaic array. The methods may include securing a torque tube to an alignment fixture by positioning a flange at an end of the torque tube over a shelf on the alignment fixture and positioning a section of the torque tube inward from the flange into a receptacle on the shelf of the alignment fixture. The method may include aligning and mounting a mount to the torque tube at a point along the torque tube inward from the end of the torque tube. The method may include aligning and mounting a solar cell module to the mount with the solar cell module including an array of lenses positioned over a set of corresponding receivers that include one or more III-V compound semiconductor solar cells. The method may include removing the torque tube from the alignment fixture after the solar cell module is mounted to the mount. The method may include aligning and mounting the torque tube to an end of a longitudinal support with the torque tube being coaxial with the longitudinal support and the solar cell module being able to rotate with the torque tube about a first axis that extends through the torque tube and the longitudinal support and a second axis perpendicular to the first axis.
