I have constructed 4 mini solar panels in series and on bright direct sunlight produces around 0.5 to 17 volts (very low milliamps). I would like to make an LDR circuit which would kick in the "charging" (the battery pack) as soon as the voltage hits 12 volts. I know that I could adjust the voltage through the resistors in the circuit pictured below.
My question is......where do I connect the positive and negative side of the battery in the circuit shown????? The picture depicts an LED coupled with a resistor (with a blue X) which will not be required. In addition, a low dropout diode is in series with the positive line from the solar panel so it will not drain the battery (although I believe that even then a .03v drop would occur).
Any suggestions or recommendations would be appreciated.
Thanks
