Abstract
A solar battery system characterized by at least one solar cell for converting light energy to electrical energy which is stored in the system is provided. The solar cell is formed of a semiconductor selected from the group consisting of single crystal, polycrystalline and amorphous substrates and is coupled in parallel to an energy-storage capacitor, which capacitor is also connected in parallel with a loading circuit. The capacitor is formed of compressed particles of activated carbon which stores electrical energy charged to it by the solar cell at a selected voltage level. A diode is coupled in series to an output terminal of said solar cell to prevent the flow of a reverse current to the solar cell during discharge of the capacitor to the loading circuit.
