WOW....
I have 120 watts of solar feeding 2 12v deep cycle batteries on the fifth wheel which seem to maintain a 55-60%. We only use LED light bulbs with only one light on for the entire evening till we go to bed.
I'm hoping I'm clear and forgive me if I'm not.
We ONLY wish to recharge laptop battery with a 12v that has a trickle charge on it. How many watt solar panel would it take? We spend most of the time in AZ. Oregon doesn't factor in on this equation.
We did 2 laptops, cell phone and tablets with two 105 aH 12 volt batteries and 400 watt inverter. The solar for that and LEDs and conservative pump or heater usage was 360 watts in full sun.
