A typical panel can put out 120 watts so it would take about 20 hours of sunlight to charge the battery.
Well add about 50 for things like charging losses and clouds.
100 amp hours useable or 1280 watts of battery in 6 hours you will need 213 watts of solar panels.
Solar charge deep cycle battery use multi stage solar charge controller which send as much available solar energy as possible to the deep cycle batteries bank for recharging.
For this system you would need seven 75 watt solar panels and four 300 amp hour batteries.
You can get the amount of energy it will provide the battery by multiplying 10 watts by 6 hours which will give you 60 wh.
This means that on that scenario the solar panel delivered 60 watts of power to charge the battery.
Typically a 300 watt solar battery charger can recharge deep cycle lead acid or lethem ion battery.
So if you have a 100ah rv battery you can charge 50 of it in a little over 8 hours 50ah 6a 8 33.
If you were using 200 watt panels you would need only three panels and four 300 amp batteries.
