Abstract[English]
We disclose a vertical-axis photovoltaic tracker that cuts wind-induced yaw torque without heavy foundations or locks. Size-bounded carriers rotate about single posts and mount panels on a horizontal hinge with a one-way downward stop, letting each panel feather freely under rear-face wind. A controller holds "rear-to-wind" within a bounded cone, minimizing yaw excitation while feathering sheds load. Multiple carriers are driven by one azimuth motor through a reeved flexible loop with positive, no-slip engagement that is torsionally compliant, sharing gust energy elastically and limiting differential azimuth. Bounding width/area shortens the yaw lever arm. The coordinated package reduces peak moments, damps transients, and supports large aggregate area per motor on single-point anchors while preserving normal sun tracking.[French]
L'invention concerne un suiveur photovoltaïque à axe vertical qui coupe un couple de lacet induit par le vent sans fondations lourdes ou verrous. Des supports limités en taille tournent autour de montants uniques et supportent des panneaux sur une charnière horizontale avec une butée descendante unidirectionnelle, laissant chaque panneau se mettre en drapeau librement sous un vent de face arrière. Un dispositif de commande maintient un "arrière au vent" au sein d'un cône délimité, réduisant au minimum une excitation en lacet alors que la mise en drapeau réduit la charge. De multiples supports sont entraînés par un moteur azimutal par l'intermédiaire d'une boucle flexible mouflée avec une prise positive sans glissement qui est élastique en torsion, partageant l'énergie de rafales élastiquement et limitant un azimut différentiel. La largeur/aire de limitation raccourcit le bras de levier en lacet. Le boîtier coordonné réduit les moments de pointe, amortit les transitoires et supporte une grande aire agrégée par moteur sur des ancrages à point unique, tout en préservant un suivi solaire normal.
