PROBLEM TO BE SOLVED: To provide a heat pump hot water supply system capable of reducing operation cost of a heat pump hot water supply device.SOLUTION: A heat pump hot water supply system S includes: a heat pump hot water supply device 1 having a heat pump type heat source machine 3, a hot water storage tank 12 and a combustion type auxiliary heat source machine 13; and an electric power measuring device 45 for measuring power generated by a photovoltaic power generation device 40 and power used in a household. It is configured in such a manner that the heat pump hot water supply device 1 can receive power generation state data by connecting the electric power measuring device 45 and the heat pump hot water supply deice 1 for communication. It includes a control unit 11 for prohibiting or controlling a hot water supply operation by the heat pump type heat source machine 3 when the power generated by the photovoltaic power generation device 40 exceeds the power used in a household and also when a predetermined condition is satisfied. |
