Abstract

La présente invention concerne un générateur d'énergie solaire destiné à flotter à la surface de l'eau et comprenant : un ensemble à flot installé de façon à pouvoir flotter à la surface de l'eau; un module de cellules solaires fixé sur l'ensemble à flot et convertissant l'énergie de la lumière incidente du soleil en énergie électrique; un moteur de pompage monté sur l'ensemble à flot, permettant de pomper l'eau du réservoir d'eau; un tube de transfert raccordé au moteur de pompage, permettant de guider l'eau pompée par le moteur de pompage à proximité du module de cellules solaires au moyen de la pression d'eau; et une partie de trombe marine, installée de façon à être en communication avec le tube de transfert et présentant une buse, pour lessiver ou refroidir la surface du module de cellules solaires. Par conséquent, la présente invention refroidit le module de cellules solaires en utilisant l'eau refroidie de sorte qu'il est possible non seulement d'améliorer l'efficacité de refroidissement et de génération du module de cellules solaires, mais également de maintenir la durée de vie du module de cellules solaires en empêchant la baisse de rendement due à la détérioration. Ainsi, la contamination de la surface et l'accumulation de neige sur le module de cellules solaires pouvant être éliminées efficacement, l'efficacité de la génération d'énergie solaire peut être améliorée.
