NOVELTY - The system has a solar cell platform having multiple solar cells e.g. gallium arsenide cell, where optical sensors and a magnet set are installed on the solar cell platform. The solar cell platform is installed in a track set having tracks (T), and a Fresnel lens set is installed at top of the track set corresponding to the solar cells. A driving device drives the solar cell platform to move the solar cells to a focus position. Another magnet set is installed on a plate corresponding to the former magnet set for maintaining an equilibrium of the solar cell platform.    USE - High-efficiency array type focusing solar tracking system for installing inside a construction material i.e. transparent material (all claimed), for providing a solar energy source to a building or construction.    ADVANTAGE - The high-efficiency array type focusing solar tracking system uses the lens set, solar cell platform, track set, driving device, plate and magnet set to move the solar cell on the solar cell platform to the sunlight and effectively collect solar energy by focusing the sunlight at the focus position through the lens set without the need of moving a heavy lens, thus achieving the effects of reducing power consumption and enhancing the electricity generation of the solar cell. The application of the solar cell emphasizes on the improved efficiency of electricity generation and the reduction of power consumption, thus finding an effective solar tracking system that reduces the system weight, minimizes the power loss and improves the electricity generation of the solar cell demanding immediate attentions and feasible solutions. The plate with the holes and optical fibers is used for collecting lights that are not focused by the lenses and using lights for other illumination applications, so as to improve the utilization efficiency of the solar energy.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a construction material comprising a high-efficiency array type focusing solar tracking system.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a mechanism for simulating operation of sun.    Sun (S)    Tracks (T)
