How many watt solar panel do i need to charge deep cycle battery.
So if you have a solar panel that with a 10 watts power rating and it is exposed to sunlight for at least 6 hours.

A typical panel can put out 120 watts so it would take about 20 hours of sunlight to charge the battery.
100 amp hours useable or 1280 watts of battery in 6 hours you will need 213 watts of solar panels.
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.
So if you have a 100ah rv battery you can charge 50 of it in a little over 8 hours 50ah 6a 8 33.
