Abstract

L'invention concerne un dispositif de suivi solaire et de nettoyage pour panneaux ou réflecteurs dans un système solaire. Le dispositif comprend un moyen imprimant un mouvement disposé sur les deux côtés d'un système solaire pour impartir un mouvement à des moyens de suivi solaire et de nettoyage. Le moyen imprimant un mouvement comprend une corde enroulée autour d'un arbre rotatif du moyen de nettoyage et possède au moins un corps fermé fixé à l'autre extrémité de la corde. Le corps fermé est logé dans un contenant de sorte que le corps fermé se déplace vers le haut et vers le bas avec les flux entrant et sortant de liquide pour imprimer un mouvement de rotation à l'arbre rotatif des moyens de suivi solaire et de nettoyage.
