but even light  from weak  light sources 
such as  fluorescent lamps,  into power.

Casio’s proprietary solar charging system

Stable operation of high-load functions

A solar panel that generates power from even a weak light source combines with a large-capacity rechargeable battery to drive multiple power-hungry functions reliably.
The area required for the LCD, dial printing and other elements is calculated precisely to permit installation of a highly resilient film-like solar panel on the dial.
Six solar cells connected in a series all receive the same amount of light.
