Solar panel battery charger

The solar battery charger circuit is nothing but a dual comparator that connects the solar panel to the battery when the voltage at the latter terminal is low and disconnected if exceeding a certain threshold. Since it is only by measuring the battery voltage, it is especially intended for lead batteries, a electrolyte liquid or gelled, that adapt the best of this way. Solar...
