The diode will kill .6 volts. As for resistors, you want a resistor to slow down current. It is current that will kill a drained battery while voltage kills a full batt. You will need to rectify the panel so that the full battery doesn't unload into the panel during off peak hours. The diode, a one way current valve, requires .6 volts to overcome the pn junction.<br><b>References : </b><br> Dont use resistors, try using a Zenor Diode. The diode will kill .6 volts.
