Abstract

L'invention concerne un système de génération d'énergie solaire qui est susceptible d'être installé, par exemple, dans un désert. L'installation d'un système de génération d'énergie solaire dans un désert n'est cependant pas facile. Une raison à cela est que la poussière dans le désert se fixe et s'accumule sur le système de génération d'énergie solaire. Par conséquent, une caractéristique de la présente invention est que la poussière est retirée en utilisant une différence de température. Selon la présente invention, la poussière peut être éliminée efficacement.
