solar light controller

Hello Group, does anyone know of a simple circuit using a basic stamp
or pic chip to turn on a 12vdc solar powered light using the solar
panel as the sensor for when to turn it on, I.E. [noparse]:([/noparse]no solar and
batt>12.1v=turn lamp on) with a battery safety (battery <12.0v=turn
off light and keep it off until next full charge) and (solar panel
volt >10=keep lamp off until solar=0.) I built this circuit with
comparators and logic gates, relay and other discreet components but
would like something simpler, maybe even using a mosfet switch to
turn
on the 12vdc lamp to save on power drain. Thanks for any input.
JOHN

    Hello: JRS

    Nice application for BS2, I have a cabin with solar panels with a solar
    controller that came with the solar system to bad you didn't not get answer to
    your question from the group, I was wondering if you had some advance on this,
    Please if you have any information send it to me,
    maybe we can shear some information once I get into this application
