A support system for a solar panel includes a triangular truss with connection points for mounting a photovoltaic module, and a cradle structure that supports the triangular truss and is connected to at least two side supports of the triangular truss. The cradle structure may be driven for rotation about an axis for tracking the sun and several cradle structures can be linked together for tracking movement using a buried linkage system. The truss may also be foldable for ease of transportation and storage.
