TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Array: The array further comprises a set of vertical supports positioned along the torque tube to support the torque tube an the solar cell modules above the earth, each of the sets of solar cell modules being separated along the length of the torque tube by one of the set of vertical supports. The torque tube includes a set of discrete sections that are connected together in an end-to-end arrangement. The drive is positioned between the two of the discrete sections. Each set of solar cell modules includes four separate solar cell modules with a first pair of the solar cell modules positioned on a first side of the torque tube and a second pair of the solar cell modules positioned on a second side of the torque tube. Also, each of the sets of solar cell modules being connected to the torque tube to rotate about a second axis perpendicular to the longitudinal axis of the torque tube. Each of the sets of solar cell modules extend perpendicularly outward from the torque tube. The torque tube includes a pipe with a diameter of 4 inches and a length of 192 inches. The array as well comprises an enlarged flange positioned at ends of each of the discrete sections, the flanges including larger areas than the discrete sections and being abutted together when the sections are connected together; and a torsion deflection mechanism attached to the exterior of the torque tube and extending between two of the discrete sections. Alternatively, the terrestrial solar tracking photovoltaic array comprises: the elongated torque tube; the set of solar cell modules connected to the torque tube and being aligned in different planes that are angularly offset relative to one another; the drive connected to the torque tube to rotate the torque tube about the longitudinal axis of the torque tube to move each of the set of solar cell modules; each of the set of solar cell modules being spaced different distances away from the drive with the angular offsets between each of the set of solar cell modules being the function of the distance away from the drive to compensate for twisting distortion of the torque tube caused by the drive rotating the torque tube; each of the set of solar cell modules being substantially aligned in a common plane after the drive rotates the torque tube a predetermined amount. The set of solar cell modules are aligned in corresponding pairs with a first solar cell module aligned on a first side of the torque tube and a second solar cell module aligned on an opposing second side of the torque tube to balance the array. The set of solar cell modules are arranged in sets of four with each of the sets being spaced apart along the length of the torque tube. The torque tube includes a set of discrete sections and the drive is connected to the torque tube at a connection between two of the discrete sections. Moreover, each of the set of solar cell modules includes a rectangular frame with a series of lenses spaced away from corresponding III-V compound semiconductor solar cells. In a second alternative case, the terrestrial solar tracking photovoltaic array comprises: the elongated torque tube supported above the earth by the set of spaced-apart vertical supports; the set of solar cell modules connected to the torque tube and longitudinally spaced along the torque tube at different longitudinal spacing; the drive connected to the elongated torque tube to rotate the torque tube about the longitudinal axis of torque tube to move each of the solar cell modules to track the sun during the course of a day; each of the set of solar cell modules having a predetermined angular orientation determined as the function of the distances of the solar cell module from the drive to compensate for differences in twisting distortion when the drive rotates the torque tube. Preferred Method: Tracking the sun with the terrestrial solar tracking photovoltaic array further comprises aligning the set of solar cell modules at a peak sun intensity during the day; rotating a first of the set of solar cell modules located in proximity to a drive through a smaller angular sweep range than a second of the set of solar cell modules located farther from the drive; and rotating a section of the torque tube operatively connected to a drive through an angular range of about 90 degrees from the initial rotational angular position to the predetermined rotational angular position. Alternatively, tracking the sun with the terrestrial solar tracking photovoltaic array comprises: applying the rotational force to the torque tube that includes the first set of solar cell modules spaced the first distance from the drive and the second set of solar cell modules spaced a greater second distance from the drive, each of the first set of solar cell modules oriented in a common plane different than the second set of solar cell modules when the torque tube is in an initial rotational angular position; rotating the torque tube from the initial rotational angular position to a predetermined angular position and tracking the sun with the first and second sets of solar cell modules during the day; and distorting the torque tube while rotating the torque tube from the initial rotational angular position to the predetermined angular position and rotating the first set of solar cell modules through a greater angular sweep range than the second set of solar cell modules.
