Socioeconomic Analysis of HY-brid Photovoltaic and Photo Heat Hot Water System

The economic of this system has been evaluated. The system is combined by the photo heat and photovoltaic: the former are made of flat plate collector (FPC), container, bracket, hose, 2 DC pumps; the later are made of solar module, bracket, wire, complex controller, battery. Heat pump water heater (HPWH) links the above two together. The system aims to afford the hot water at all climate and send the surplus power to the grid. This paper analyzes from input, output and environmental protection, which shows the people the advantages and disadvantages of the system. The system has been set up in Guangzhou, China.
