NOVELTY - A solar energy power supply system comprises a solar battery that receives light or heat to generate electric power, electrolyte supplying device, electrolyte recycling device, a hydrogen recycling device to provide recycled hydrogen to a fuel cell to continuously generate electric power when light and heat are not available and provide heat to the solar battery by a heating device, and a power management device.    USE - As a solar energy power supply system.    ADVANTAGE - The system can generate electric power whether light or heat is available or not. It is a full time power supply system to improve practicability, and can be assembled to form various combinations according to different requirements of product sizes, costs, or utilization. The operation principle remains unchanged.    DETAILED DESCRIPTION - A solar energy power supply system comprises:    (1) a solar battery;    (2) an electrolyte supply device to provide an electrolyte;    (3) an electrolyte recycling device (3) having a cooler (31) and a first recycling tubing;    (4) a hydrogen recycling device having a container (41), a second check valve, and a filter;    (5) a fuel cell (5) having a third check valve (51), a first solenoid valve (52), and a second recycling tubing;    (6) a heating device having an automatic igniter, a gas nozzle (62), and a second solenoid valve (63); and    (7) a power management device (7) having a controller (71), a storage battery, a direct current (DC) socket, and an alternating current (AC) socket.    The controller charges the storage battery with electric current generated by the solar battery and the fuel cell through a circuit. The storage battery (74) delivers the stored electric power through the circuit to the controller to supply AC and DC power to the AC socket (73) and the DC socket (72). The controller controls power ON/OFF of the solenoid valves and the automatic igniter through three different circuits. At least four sets of tubing bridge the electrolyte (15) supply device and the solar battery, the electrolyte recycling device and the solar battery, the hydrogen recycling device (4) and the electrolyte recycling device , and the fuel cell, the hydrogen recycling device and the heating device (6) respectively. Electric power generation is accomplished by first injecting the electrolyte into the solar battery through the tubing. The solar battery receives light or heat to generate the electric power and produce water vapor (9) and hydrogen gas. The water vapor is sent to the electrolyte recycling device through the tubing to be cooled by the cooler to become liquid water that is sent to the solar battery through the first recycling tubing of the electrolyte recycling device to be recycled and reused. The hydrogen gas is sent to the hydrogen recycling device through the tubing to be recycled. When the light or heat is not available the recycled hydrogen gas is selectively delivered through the tubing to the fuel cell or the heating device to produce heat to heat the solar battery to generate the electric power continuously. Electric current generated by the solar battery and fuel cell is controlled by the power management device to comply with electric power specification for final usage.
