【 摘 要 】

To solve the problems that the gradual depleting of fossil fuels and the increase of CO2 emission. A solar system combined heating and electric powder in buildings has been proposed and analysed, which contains a solar-thermal subsystem and a photovoltaic subsystem. Taking a family house in Jinan as an example, the area distribution between solar collectors and the PV panels and the operating years were optimized aiming for achieving the cost benefits of the system. Meanwhile, the economic saving of the system is analysed with a solar-thermal system as a reference object. Results show that annual mean cost of the proposed system is much decreased firstly and then the decrease of it slows down, with the increase of the area ratio between PV panels and solar collectors. Meanwhile, that is decreasing with the increase of the operating years. In addition, the proposed system can save more energy than that reference when the heating is assumed the same.
