    Solar charge.

    Hi dudes i have a pertinent doubt : there is difference between recharge in the sun and at the shade ? The generated power by the solar panel varies or there is a fixed limit despite the clarity ?

    It charges faster in the sun

    I am asking this because i have a Casio solar calculator that works fine when it is in the shade (screen digits are very bright).

    Read the watch manual and you will understand. Charging in the shade is very slow.

    Re: Solar charge.

    According to the charging chart from the GW-6900, charging in direct sunlight is approximately ten times more efficient than charging through a window on a cloudy day:

    If that chart were to include "in the shade" I'm not sure where it would be, but charging in the shade is definitely less efficient than "in direct sunlight."

    I knew you would post that chart so I didn't bother. What drives you to go out of your way to be so helpful?

    In this particular case, it's because last year I started saving every Casio chart I posted to a sub-folder, so now I have almost-instant access to quite a few of them!

    Re: Solar charge.

    It is possible to know how much volts or mvolts are generated in direct sunlight? Once i measured a garden solar led light and gave readings of + 1 volt.
