a kind of efficient heat transfer components, was designed to fit on the back of photovoltaic cells to form the photovoltaic thermal (PV/T) component[2]. The MHPA-PV/T module has many technology advantages, such as larger contact area, reliable operation, no medium leakage risk, and lower investment, simple manufacturing, etc. Preliminary tests in Beijing showed [3] that the component can reduce the temperature of photovoltaic cells effectively, improve power generation efficiency while collecting hot water. The new MHPA-PV/T module performance is excellent and it will be widely used in different region. This paper built a mathematical model of the household MHPA-PV/T system and simulated system operating performance in different regions, to predict the long-term application effect of the systems in different regions of China and to provide theoretical basis for its practical application.
