The present invention provides a solar cell that can be utilized as a stable electric power source for cloudy weather. An output voltage V1 of the solar cell 1 is lowered by a DC-DC converter 5. When a battery V2 is charged with an output of the converter 5, the converter 5 is stopped and the power of only the battery V2 is supplied to a low-voltage inverter circuit 6.

While the electric power of the converter 5 is increased, the performance of the solar cell 1 is judged. When the performance is decreased, the output voltage from the converter 5 is lowered and the amount of electric power supplied from the battery 2 is increased relatively.
