The invention discloses an independent energy-supply solar heat collection water boiler which is characterized by comprising a solar energy energy-supply control device, a solar energy heat collection water boiler and a universal rotation device. A single crystal solar panel absorbs luminous energy which is converted by a controller charger to be stored in a storage battery, then 12v power supply is output by the storage battery to be supplied to control system equipment of the water boiler and lighting of the water boiler, and the control device controls a water pump and a solenoid valve at one end of a water inlet and a sensor at one end of a water outlet. Sunlight is absorbed and converted by a solar energy collector tube to be transmitted to a solar energy heat conduction tube which transmits heat to a U-shaped circulating tube. Cold water is led in from the water inlet to enter the U-shaped circulating tube, and the U-shaped circulating tube heats the cold water. When water temperature at one end of the water outlet achieves setting temperature, the water can automatically enter a boiling water barrel. The universal rotation device is placed at the lower end of the solar heat collection water boiler, and the direction of the universal rotation device is adjusted to face the sunlit direction. The independent energy-supply solar heat collection water boiler has the advantages of being environment-friendly, healthy, free of energy dissipation, free of pollution, durable, long in service life and the like.
