NOVELTY - The field of interconnected solar tracker assemblies has solar tracker assemblies (100) each having oblique-angled, rhombus frame (10) with four leg assemblies (30) interconnected by sides of equal length, and one or more solar tracking units (200) mounted on four leg assemblies. The movement of solar tracking units in relation to at least one axis is controlled by a local control unit associated with the solar tracker assembly. The solar tracking assemblies are arranged with regular spacing in the field so that adjacent sides of adjacent pair of the solar tracker assemblies are parallel.    USE - Field of interconnected solar tracker assemblies for solar tracking apparatus.    ADVANTAGE - Reduces or eliminates need for ballast such as concrete block and facilitates electrical connection and data communication since individual panels are mounted at or near their center of gravity and positioned at corners or junctions of the frame and panels are physically interconnectible in the field for enhanced stability. The arrangement of interconnected structures in solar farm or sub-farm provides for efficiency in grounding the supporting structures of the solar tracking units. Reduces need for expensive connectors since trusses carry cables, wires or hoses in their respective upper or lower chords and prethreaded through the chords prior to shipping to minimize assembly time in the field, as well as shield the wiring from the elements. The panel design reduces the amount of energy required to drive the panel between different orientations, and assists in maintaining tracking accuracy. The trackers are interconnected with pre-measured spacing arms to minimize installation time, as well as optimize field layout for minimal tracker-to-tracker shading. The interconnection enhances the structural solidity of frames overall, and reduces the need for external ballasting of the frames.
