Researchers at the University of Bologna have released a study on photovoltaic-thermal solar-assisted heat pump (PV/T-SAHP) systems for buildings. The research examined the integration of photovoltaic thermal (PV/T) and heat pump (HP) technologies to improve building energy efficiency. It reviewed literature on effectiveness, feasibility, and performance metrics of PV/T-SAHP systems. The study analyzed hybrid PV/T collectors, which generate both electricity and thermal energy, improving system reliability. SAHP systems were categorized into direct expansion (DX) and indirect expansion (IDX) configurations, with evaluations of their performance in different climates. Key numerical findings on direct expansion systems were summarized. The review emphasized PV/T-SAHP systems' potential to reduce energy consumption and carbon emissions in buildings. Future research directions were identified to enhance system design, integration, and performance for broader low-carbon applications.
