These Circuits will allow for Voltage Regulation and Isolation when Charging Lead Acid Batteries with a Solar Cell.
I also suggest you read my Amplified Zener Article,
For MORE DETAILS.

The "RX" Resistor "that is used on the Amplified Zener" is Not Needed for this Solar-Charger. Solar Panals are basically a current limited device. Therefore the output voltage will pull down accordingly, as the load increases.
"Here is the Schematic"
Possibly good for up to 5 Amps.
"Here is a Schematic for More Current."
Good for Higher currents and can be Expanded with More Transistors.
