Abstract

Abstract. The article studies the efficiency of photovoltaic thermal of different capacities with a new type of cooling system designed for an arid dry climate. There are presented the results obtained on a 1 kW photovoltaic thermal device. To begin with, the article presents the efficiency of photovoltaic thermal based on 60 W and 180 W photovoltaic batteries and the results obtained on a 1 kW photovoltaic thermal. Several factors should be taken into account when using renewable energy sources in extremely dry regions of our republic including extremely high temperatures. At such high temperatures (40℃ and above in the shade) the efficiency of photovoltaic batteries decreases, some of the energy we need is lost. In order to decrease these losses, it is important that water is not constantly needed to cool the photovoltaic thermal. The new type of cooling system that we offer has no analogues in the world. In further scientific research, the goal is to further improve new type of cooling system and transfer it to work in an autonomous manner.
