This invention deals with novel method and apparatus for positioning and motion control of a solar cell system that tracks the sun or other light source. This achieves an advantageous increase in output power. The torque to produce angular deflection, and rotational motion is provided separately by an induced and/or permanent dipole coupling to an electronic grid. Thus forces and torques are produced without the use of internal moving parts such as in motors. The instant invention exceeds the capability of conventional systems. It is suited for maximization of solar energy with an ideally low-profile tracking solar cell array. Since there are no motors or other heavy and expensive equipment, the instant invention provides less costly and greater ease of manufacture, transportation, and installation. Dynamic motion can be controlled over a wide range of dimensions from micrometers to decimeters.
