NOVELTY - The platform has extensible legs (22) attached to a top tube frame chord (24), an end frame chord (48) and a center frame chord (26) of a truss frame. An assembly (11) is mounted between the legs and the end frame chord, and includes an actuator (44) e.g. servo motor, moving the end frame chord. A solar altitude adjustment unit adjusts height of one of the frame chords. Movable feet (30) are attached to the extensible legs, and are spread 90 degrees. The actuator is powered by electric power, air pressure or hydraulic power.    USE - Platform e.g. solar tracking platform (claimed) such as multi-array solar tracking platform, for tracking a trajectory of a sun during a day time for providing solar energy to an electric vehicle i.e. car.    ADVANTAGE - The platform maximizes the solar ray collection and the efficiency of a solar support system, and can be mounted in an East-West configuration or a North-South configuration, either on the top of a structure or on the ground, or can be ground mounted on extreme sloped hillsides, rough ground locations and orientated in a complete vertical position, thus efficiently providing the extra energy to the electric vehicle. The platform can be easily mounted to the most stable and structurally sound roofs with a minimum of disruption to roof penetrations, and can be easily removed and reinstalled for roof repair. The platform is pre-assembled and packaged, such that the platform can be easily transported and installed at remote locations, and footprint size, hardware costs, potential roof leaks and man-hour labor costs are reduced. The platform allows solar power to be used in unique and creative ways. The platform can be more efficient in certain locations if mounted to allow solar altitude adjustment.    DETAILED DESCRIPTION - The frame chords are made from material e.g. hollow aluminum tubes, carbon fiber, steel, fiberglass, impregnated material, laminated fibrous material, plasticized material, impregnated wood, straw, or recycled material.
