1. A heat pump hot-water supply system, comprising a heat pump hot-water supply device, a storage tank for storing hot water obtained by operating the heat pump hot-water supply device, and a control device for controlling operation of the heat pump hot-water supply device,wherein the control device is configured to acquire outside air temperatures of a place where the heat pump hot-water supply device is installed,wherein the acquired outside air temperatures include a predicted highest outside air temperature of the current day and a predicted highest outside air temperature of a next day, andwherein the control device is configured to compare the predicted highest outside air temperature of the current day and the predicted highest outside air temperature of the next day, andwherein, if the predicted highest outside air temperature of the current day is equal to or higher than the predicted highest outside air temperature of the next day, the control device operates the heat pump hot-water supply device in a time zone of the current day to which the predicted highest outside air temperature of the current day belongs, andif the predicted highest outside air temperature of the current day is lower than the predicted highest outside air temperature of the next day, the control device operates the heat pump hot-water supply device in a time zone of the next day to which the predicted highest outside air temperature of the next day belongs.
