With recent research and development example, the compound utilization with the heat source equipment for the residence is proposed the solar energy utilization. For example, gas domestic hot water supply and heat pump heating and cooling system and combination example the contribution ratio of combined photovoltaic and heat system is high, if solar energy system can be operated under optimum conditions, and the energy consumption becomes an optimum. From the viewpoint of economical efficiency, environment, this report was evaluated on the effect (effectiveness of the system) of combined photovoltaic and heat system for the housing using the practical operation case.
