Title (EN) INSTALLATION FOR AUTOMATICALLY DIRECTING A SOLAR ENERGY CONCENTRATION REFLECTOR
(FR) INSTALLATION POUR DIRIGER AUTOMATIQUEMENT UN REFLECTEUR DE CONCENTRATION DE L"ENERGIE SOLAIRE
Abstract:
(EN) To control a reflector so that it tracks the apparent motion of the sun in order to concentrate the solar light on an absorber, a movable device is used which is connected to the reflector and actuated by a DC motor (5). The connections of the motor are connected with a parallel circuit comprised of two solar cells (9, 10). The parallel circuit is arranged so that with a uniform irradiation both cells produce equal but opposite voltages. The motor is actuated by the differential voltage appearing at the parallel circuit. Both solar cells are secured to the absorber portion wherein the rays are focused. Both cells are arranged symmetrically to the longitudinal axis of the absorber. Thus, the reflector is automatically positioned so that the rays are concentrated to the absorber and no additional energy is required to actuate the reflector.
(FR) Pour commander un réflecteur et lui faire suivre le mouvement apparent du soleil de manière à concentrer la lumière solaire sur un absorbeur on utilise un dispositif mobile lié au réflecteur et actionné par un moteur à courant continu (5). Les connexions du moteur sont connectées avec un circuit parallèle constitué de deux cellules solaires (9, 10). Le circuit parallèle est agencé en sorte que lors d"une irradiation uniforme les deux cellules produisent des tensions égales mais opposées. Le moteur est actionné par la tension différentielle aparaissant sur le circuit parallèle. Les deux cellules solaires sont fixées sur la portion de l"absorbeur où les rayons sont focalisés. Les deux cellules sont disposées symétriquement à l"axe longitudinal de l"absorbeur. Ainsi le réflecteur prend automatiquement une position telle que les rayons sont concentrés sur l"absorbeur et aucune énergie supplémentaire n"est nécessaire pour actionner le réflecteur.
