How much solar power do i need for my rv.
How many solar panels needed to recharge an rv battery.
You have 300 watts of solar panels on your camper s roof and two 12 volt batteries.
Since it s a 60w setup it s the most portable panel to deal with in terms of weight.
If you have two 100ah batteries wired in parallel you have 200ah capacity.
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.
So to recharge them from 50 would take 17 hours with a 100w panel.

As the name implies it s a 60w solar panel made up by two efficient 30w monocrystalline panels.
Unless you knowingly have upgraded your batteries i bet you have 100ah or less in total and a 100w panel will be enough to recharge your battery as long as it s sunny.
If your usage of day stands at around say 140 amps hour then try getting 4 5 solar panels of 100 watts.
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.
In this case you ll most likely end up with a 15 amp charge controller.
The number of solar panels required to install an rv depends on the number of batteries you need to charge it.
For a single 12v battery at around 100 ah you should have at least 300w solar panels.
You should be able to get close to around 30 amps with one 100w panel and can multiple it with more panels as needed.
A 10a solar charge controller is built in as well to protect your 12v rv batteries from overcharging.
Knowing whether the battery is being charged or not.
With this number you know that you ll need a charge controller that can provide more than 12 5 amps of power to your battery bank.

Our final personal determination.
For our specific power demands we need one 100 watt portable solar panel to recharge our rv batteries during our boondocking camping trips under normal conditions.
The more ampere hours you have the more solar panels you will need.
