Thermal Energy Storage for Load Shifting

Physics Professor Pete Schwartz has a hot tub in his backyard and four 425 Watt solar panels on his roof. Currently, his panels heat his hot tub directly using resistive heating elements, and he cannot use his hot tub in the evening. Our team, Ra Energy, designed a thermal energy storage system, so Dr. Schwartz can use his hot tub after the sun sets. Energy storage can shift electrical load away from the late afternoon when people return to their homes, and it is a crucial technology necessary to create a sustainable future.
