The Photovoltaic/thermal (PV/T) system combines the conventional PV panel with solar collector into one integrated system, which could achieve function of generating power and providing thermal energy at same time. Recently, it has become most promising for building applications. Most PV/T systems use water as coolant, cause freezing problem in winter. To overcome this problem, heat pipe is dev...

Abstract Photovoltaic-thermal (PV/T) systems and hydronic radiant floor heating can enhance energy efficiency economic viability. This study investigates their integration through experimental research designs an experiment to test performance under typical winter conditions. The heat pump system achieves average COP of 5.66 photovoltaic power output 107.5 W. underfloor quickly reaches maintain...
