Abstract

Comme les unités de cellule solaire de la présente invention sont empilées et montées autour d'un pôle électrique, les risques d'endommagement ou de dysfonctionnement dus à une bourrasque sont réduits et, comme les panneaux de cellules solaires sont montés tout autour, il n'est pas nécessaire d'amener ces panneaux sur des positions optimales par rapport à la trajectoire du soleil. De plus, il est possible de fournir l'énergie requise en jouant sur le nombre d'unités de cellules solaires en fonction de la puissance demandée pour l'éclairage urbain. Par ailleurs, comme seule une petite cellule solaire tourne, et non la totalité du panneau solaire, la puissance requise pour ce mouvement de rotation et les coûts de montage peuvent être réduits et aucune restriction n'est imposée quant à l'emplacement de l'installation.
