Solar Cell charges a NiCd AA cell when darkness falls

Reverse engineered circuit diagram of a popular mass produced solar light. The light automatically turns on when there is no light falling upon the solar cell, so the parts count is minimal. The charging circiut is not particularly efficient since the battery must charge through a plain diode.

Solar Battery 1.2V Charger

This instructable will show you how to make your own solar battery charger from very simple components. It is taken from my documentation provided with a kit I supply – you should easily be able to source the same components yourself of course.

Solar charger for lead-acid battery by LM339

This circuit is intended for charging lead-acid batteries with a solar panel. The customary diode that prevents the battery from discharging through the solar panel has been replaced by a FET-comparator combination. The charger will stop charging once a pre-set voltage (temperature compensated) has been reached, and recommence charging when the voltage has dropped off sufficiently. The load is disconnected when the baterry voltage drops below 11V and reconnected when it gets back to 12.5V.
