NOVELTY - The power regenerative solar water heater system comprises a storage water tank, a bracket, a collecting pipe, cylindrical shaped phase change heat storage material and solar energy panels, where the solar energy panels are mounted on an upper part of the solar panels bracket. The solar energy panels and the solar panels bracket are connected with a rotating shaft. The solar energy solar panels are connected with a motor by a storage battery. The rotating shaft is provided with a collecting overpass type two-degree-of-freedom wrist or offset two-degree of-freedom wrist.    USE - Power regenerative solar water heater system.    ADVANTAGE - The system has strong sun light irradiation effect, good heat insulating and energy saving effect, and is capable of collecting pipe heat without over-heating hot water.    DETAILED DESCRIPTION - The power regenerative solar water heater system comprises a storage water tank, a bracket, a collecting pipe, cylindrical shaped phase change heat storage material and solar energy panels, where the solar energy panels are mounted on an upper part of the solar panels bracket. The solar energy panels and the solar panels bracket are connected with a rotating shaft. The solar energy solar panels are connected with a motor by a storage battery. The rotating shaft is provided with a collecting overpass type two-degree-of-freedom wrist or offset two-degree of-freedom wrist. The phase change heat storage material and 40-60% of adjusting component. The phase change heat storage material is coated on a concave-convex surface of a circular or a rectangle shaped heat storage grid. The heat storage grid is mounted with the storage water tank. The storage water tank is provided with a water level detecting device, a temperature detecting device and an electrical heater. The electric motor, the storage battery, the water level detecting device, the temperature detecting device and the electrical heater are connected with a controller. The controller comprises a single chip machine, a keyboard, a display screen, a temperature acquisition circuit and a water level detection circuit.
