Residential heat pumps linked to solar-plus-storage achieve higher seasonal performance factor

Researchers at Germany's Frauhofer ISE have analyzed the performance of a residential heat pump connected to a rooftop PV system relying on battery storage and have found that this combination significantly improves the performance of the heat pump while also increasing considerably the solar array's self-consumption rate. A group of researchers at Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) investigated the performance of smart grid-ready heat pumps (HPs) combined with rooftop solar power generation and battery storage in single-family houses and found that both ...
