  • Publication number: 20090084429
    Abstract: Stand-alone, interactive modular solar-energy-production system. This system consists of an oblong frame that supports the photovoltaic field that receives the solar energy, an azimuth/zenith tracker, an actuating means generator and computerized control means. The base of the frame is supported in a rotary fashion on a shaft fixed securely in the ground and is supported by rolling means that can move in a rotary fashion over the ground with respect to said fixed shaft. During rotation, the rolling means adapt to the ground via tilting means associated with the fixed shaft that enable the frame to maintain balance. The base is coupled to said fixed shaft in an off-centre position and the rolling means, also, are off-centre with respect to said fixed shaft, which enables the frame to be oriented with respect to the wind in the manner of a wind vane.

  • Patent number: 6642691
    Abstract: An autonomous interactive solar energy production system including a base secured to a floor, a parallelepiped body that swivels on the base including a tilting face fitted with a filed of photovoltaic, thermal and/or mixed cells, a solar energy collector, whose uptake field makes two movements for tracking the sun, one along the azimuth between 0 and 280° between sunrise and sunset, and the other along the zenith between 90 and 45°.

  • Publication number: 20020190688
    Abstract: The system disclosed in the invention comprises a base affixed to the ground, a parallelepiped body that can rotate relative to the base and having a swivel-mounted face provided with the thermal and/or mixed photovoltaic field capturing the solar energy, said capturing field carrying out two moments to follow the sun, the first movement being in azimuthal direction between 0 and 280° from sunrise to sunset and the second movement being in zenithal direction between 90 and 45° from the horizon to the Sun's zenith by means of an azimuthal/zenithal tracking device, said field being placed perpendicular to the sun with the purpose of maximizing photon capturing. A power generator is located between the body and the base, said generator being mounted centrally and independently of the body and the base. The system includes combined computer means enabling autonomous and interactive operation of all components.
