Self-ballasted apparatus for solar tracking

Abstract: A frame for mounting a plurality of solar tracking units is provided. The frame comprises a plurality of leg assemblies interconnected by trusses to provide a stable structure that is ballasted by the frame's own weight, rather than relying on external ballast such as concrete blocks. Each leg assembly is provided with a shaft with a mounting end for mounting a solar tracking unit. Each solar tracking unit includes an armature assembly and at least one motor for controlling the orientation and position of a solar panel mounted thereon. Solar tracking assemblies, each comprising the frame and plurality of solar tracking units, can be assembled in an array using connectors spacing the assemblies, thus providing enhanced stability. Each of the assemblies can be provided with a local control unit for controlling each individual solar tracking unit, and a global control unit may be used to control the local control units.
