PURPOSE:To realize a high-efficiency use of solar energy by a method wherein a solar battery, a superconductive coil consecutively storing the excess out of the electrical energy to be stored in the solar battery, and a switch capable of automated switching are provided. CONSTITUTION:During the daytime and when solar rays are available, the light incident on a solar battery 1 is converted into electricity by the solar battery 1. The electricity is stored in the solar battery 1 or supplied to a controller 4. Excess electrical energy not absorbed by the solar battery 1 is fed into a superconductive coil 2 for storage as a permanent current. When solar optical energy is not available for night or cloud, or when there is a shortage of energy stored in the solar battery 1, a switch 3 is operated, for the use of electrical energy stored in the superconductive coil 2. The electrical energy from the superconductive coil 2 is fed to the controller 4 for its activation. |
