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.
How many watt solar panel do i need to charge deep cycle battery.
A typical panel can put out 120 watts so it would take about 20 hours of sunlight to charge the battery.
In this video i show the renogy 100w panel and how to connect it to a camper.
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.
So if you have a 100ah rv battery you can charge 50 of it in a little over 8 hours 50ah 6a 8 33.

Well add about 50 for things like charging losses and clouds.
Typically a 300 watt solar battery charger can recharge deep cycle lead acid or lethem ion battery.
213 watts of solar x 6 hours 1280 watts of stored power 213 watts of solar x 6 hours 1280 watts of stored power.
For this system you would need seven 75 watt solar panels and four 300 amp hour batteries.
That is about 2400 watt hours.
100 amp hours useable or 1280 watts of battery in 6 hours you will need 213 watts of solar panels.
50 is 50 of our 100ah battery and 6 is how many amps the 100w solar panel is generating.
