A solar energy collection system (300 A, B, C), comprising: a frame comprising a plurality of tracking units for mounting the system (300 A, B, C) on a suitable substrate, said frame having a longitudinal axis; and a plurality of solar panels disposed adjacent to one another on said frame, each of said solar panels comprising a top surface for converting solar energy into electrical power; characterized in that: a first set of said solar panels are movable about hinge shafts relative to a second set of said solar panels, the hinge shafts lying along hinge daily axes, for tracking movement of the sun during the day, the hinge daily axes lying in orientations which are perpendicular to an orientation of the frame axis; and further wherein solar panels of said first set are arranged in alternating fashion with solar panels of said second set, each of said tracking units comprising a first solar panel in the first set and a second solar panel in the second set; wherein a first solar panel in said first set is pivotally connected by one of the hinge shafts to a second solar panel in said second set, about one of said hinge daily axes, to form one of said tracking units; and the solar energy collection system further comprising a drive system (28, 30, 32, 34) for pivoting each of said first and second panels in a tracking unit, wherein said frame comprises a structural channel, and a plurality of said tracking units are disposed along said structural channel to form a tracking assembly, and wherein said drive system (28, 30, 32, 34) comprises a drive shaft extending lengthwise through said channel, and a plurality of camming systems (36, 38) attached to said drive shaft, and further wherein each of said first and second panels in each said tracking unit pivots about its hinge daily axis independently of the other of said first and second panels in that same tracking unit. a frame comprising a plurality of tracking units for mounting the system (300 A, B, C) on a suitable substrate, said frame having a longitudinal axis;
