Wind-solar hybrid system for domestic water heating

Abstract

Goal: The invention relates to domestic water heating systems, namely heating with wind and solar thermal energy. It makes the most of wind and solar energy potential at various times of the year. In the cold period of the year, when the wind energy potential is better, the wind turbine produces more thermal energy needed including for heating residential spaces, compensating for the deficit of thermal energy generated by the solar thermal installation, which in the cold period of the year has a conversion efficiency smaller. During the warm period of the year (with maximum solar radiation) the solar thermal installation has maximum solar energy conversion efficiency, when the wind turbine has reduced conversion efficiency due to the relatively low wind energy potential during the April - September period of the year.
