It uses a single LR44 1.5V cell as backup and auxiliary power for the solar panel.

The solar panel generates 1.8VDC under strong light.

It seems SHARP uses a single internal PCA design for all Colourful Scientific Calculators series.
A table with seven models can be selected by changing the hardware jumpers. I didn't test it.

The solar panel is more sensitive to what can be found on the CASIO fx-991 series.
Under the same conditions, the CASIO machines will not power on, requiring either more light or a battery cell to be able to work.

The keyboard construction is similar to what we see on CASIO machines.
A rubber membrane and discrete plastic keys.
