Abstract

La présente invention concerne un appareil photovoltaïque. L'appareil photovoltaïque comprend : une plaque de cellules solaires ; une plaque réfléchissante, disposée de manière à pourvoir tourner sur un côté de la plaque de cellules solaires afin de réfléchir la lumière solaire sur toute la surface de la plaque de cellules solaires ; et une partie d'entraînement de la plaque réfléchissante, permettant de faire tourner la plaque réfléchissante par rapport à la plaque de cellules solaires. Selon la présente invention, étant donné que la lumière réfléchie par la plaque réfléchissante disposée sur une extrémité de la plaque de cellules solaires est irradiée sur toute la surface de la plaque de cellules solaires, il est possible d'accroître de manière significative la quantité de lumière irradiée sur la plaque de cellules solaires afin d'accroître de manière significative la quantité d'électricité générée par rapport à la quantité générée par une plaque de cellules solaires classique. L'appareil photovoltaïque trouve ainsi une application beaucoup plus large en tant qu'appareil photovoltaïque à échelle réduite qui est installé dans les réverbères, les maisons, etc., qui disposent de surfaces d'installation relativement restreintes.
