What size solar panel to charge a 6v battery?
When your battery is 6v but the solar panel is 12v you must reduce 6v from the output voltage to prevent any damage to your battery. If you do not have a voltage controller for this task you can simply connect a bulb in series with the battery. So the bulb will take 6v from the output voltage and the only 6v will be supplied to the battery.
