Abstract:
1. A solar energy power supply method, comprising the steps of: providing a solar battery and an electrolyte supply device connected to the solar battery through a first tubing to provide an electrolyte to the solar battery, wherein the solar battery receives either light or heat to generate electric power and produce water vapor and hydrogen gas; providing an electrolyte recycling device connected to the solar battery through a second tubing and a first recycling tubing, wherein the electrolyte recycling device includes a cooler which receives the water vapor from the solar battery through the second tubing, and the cooler cools the water vapor to become liquid water and sends the liquid water to the solar battery through the first recycling tubing so that the water vapor can be recycled and reused; providing a hydrogen recycling device connected to the cooler through a third tubing which is connected with the second tubing, wherein the hydrogen recycling device includes a container, a second check valve and a filter, and the container stores the hydrogen gas produced by the solar battery through the second tubing, the hydrogen recycling device and the third tubing; providing a fuel cell connected to the electrolyte recycling device through a second recycling tubing, which includes a third check valve, a first solenoid valve; providing a heating device connected to the hydrogen recycling device and the fuel cell through a fourth tubing which includes an automatic igniter, a gas nozzle and a second solenoid valve, wherein the hydrogen gas stored in the hydrogen recycling device is sent into the gas nozzle through the second solenoid valve which is connected with the fourth tubing, and the automatic igniter burns the hydrogen gas coming from the gas nozzle to provide heat for the solar battery and the electrolyte supply device; providing a power management device which includes a controller, a storage battery, a DC socket and an AC socket; directing with the controller charging of the storage battery with electric current generated by the solar battery and the fuel cell through a circuit, the storage battery delivering the stored electric power through the circuit to the controller to supply AC and DC power to the AC socket and the DC socket, the controller controlling power ON/OFF of the first and second solenoid valves and the automatic igniter through three different circuits; and wherein when the light or heat is not available the controller selectively delivering recycled hydrogen gas through the tubing to either 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 the fuel cell being controlled by the power management device to comply with electric power specification for final usage.
