DOES SOLAR HEATING WORK WITH AUXILIARY HEAT SOURCE AND THERMAL ENERGY STORAGE

Solar energy storage in summer and heating in winter

Seasonal thermal energy storage (STES) harvests and stores sustainable heat sources, such as solar thermal energy and waste heat, in summer and uses them in winter for heating purposes, facilitating the replacement of fossil fuel-based heat supply and coordinating the seasonal mismatch between heat supply and demand [7].
