3 is a control circuit, 4 is a load circuit, and the output of the solar cell array 1a and the solar cell array (for control) 1b is such that the solar cell output voltage V0 increases the load current of the solar cell. The control circuit 3 utilizes the non-linearity characteristic of the solar cell, which decreases due to
The solar cell array (for control) 1 is adjusted so that the output voltage V
The number of batteries flowing from b to the load circuit 4 is increased or decreased, the output voltage V 0 in FIG. 1 is controlled to a constant value or below a constant value, and the power generated by the solar cell is converted into a DC power source. Further, the charging control circuit 5 charges the storage battery 6 while adjusting the current, and when the storage battery 6 is in the shade, the output voltage V 0 is generated by discharging the storage battery 6. Therefore, as shown in FIG. 2, the output voltage V 0 changes over time from C 1 in sunlight to C 2 in shade, resulting in large fluctuations.
