Abstract

La présente invention concerne un suiveur solaire destiné à des installations de production d'énergie électrique au moyen de panneaux photovoltaïques, lequel suiveur solaire permet d'orienter de façon spécifique les panneaux en fonction de la position du soleil, de manière à obtenir une insolation maximale sur ceux-ci à tout moment de la journée. Les panneaux sont fixés à un ensemble support-grille (3) qui peut tourner au moyen de liaisons articulées selon une rotation zénithale et qui est actionné par un moteur (16) afin de se rabattre sur un ensemble base (7) ou de s'éloigner de celui-ci. Un ensemble bras-patin (11) est relié de façon articulée à l'ensemble base (7) et de façon articulée et coulissante à l'ensemble support-grille (3). Un moteur (20) actionne l'ensemble base (7) afin qu'il effectue une rotation azimutale de 240°. Les moteurs sont programmés et commandés par un PLC. La géométrie du suiveur solaire selon l'invention offre un avantage important en termes de sécurité étant donné que le panneau photovoltaïque se trouve plus proche du sol que les panneaux photovoltaïques utilisant des suiveurs solaires de la technique antérieure et ce, dans n'importe quelle position possible.
