Abstract

A solar cell system for supplying electric energy from solar cells to loads. This solar cell system includes solar cells for converting light energy into electric energy, an electric double layer capacitor for storing the electric energy from the solar cells, and a discharge controller for causing the electric double layer capacitor to discharge electric energy to the loads intermittently in predetermined cycles while charging the electric double layer capacitor. A period of time for discharging is shorter than a period of time for charging, and a current discharged to the loads is larger than a charging current applied to the electric double layer capacitor.
