Abstract[English]
A wind-responsive photovoltaic tracker system for single-post foundations is disclosed. Each tracker yaw-rotates about a vertical axis and supports modules feathering passively about a horizontal hinge. Directional bracing raises swing-mode frequency, while a pretensioned flexible drive with bounded compliance and wind-aligned yaw control reduces aerodynamic loading, detunes resonances, and dissipates gust energy.[French]
L'invention divulgue un système de suiveur photovoltaïque sensible au vent pour des fondations à un seul montant. Chaque suiveur tourne en lacet autour d'un axe vertical et supporte des modules oscillant passivement autour d'une charnière horizontale. Le contreventement directionnel élève la fréquence en mode oscillant, tandis qu'un entraînement flexible précontraint avec une conformité limitée et une commande de lacet alignée sur le vent réduit les charges aérodynamiques, désaccorde les résonances et dissipe l'énergie des rafales.
