In this paper, two detached houses with photovoltaic system and all-electrified residential equipment were chosen as the research object. The hourly operating situation of electricity genera-tion of photovoltaic system and electricity consumption were investigated. Based on the recorded data, the combination using of the photovoltaic system with the high efficiency equipment, CO2 heat pump hot water heater, also has been examined. The introduction effect of the photovoltaic system was evaluated from the view of energy saving, environmental and economic effect based on the electricity situation such as price, greenhouse gas emission and so on.
