Abstract:
1. A solar tracking system for mounting on a roof having one or more rooftop planar surfaces, comprising: an array of solar tracking assemblies for at least one of the one or more rooftop planar surfaces, each array of solar tracking assemblies mountable at substantially the same orientation on the rooftop planar surface, each solar tracking assembly including a mounting structure, a steering mechanism, and one or more energy converting units that convert solar energy into electrical energy, the steering mechanism supported at least in part by the mounting structure and the one or more energy converting units steered by the steering mechanism; a drive mechanism that drives multiple steering mechanisms of the array of solar tracking assemblies; and a control processor that controls the drive mechanism so that the one or more energy converting units follow the sun, wherein the steering mechanism includes three parallel rotary shafts providing two rotational degrees of freedom and a translational degree of freedom up and down of the one or more energy converting units.
