As we talked about above a 12v 100ah battery is 1200wh 12 100.
How many watt solar panel do i need for rv.
We can also think about it in watt hours.
5 hours of direct sunlight x 6 amps generated hour 30 amp hours day.
If our 100w solar panel generates 70w every hour it will take a little over 17 hours to generate 1200wh 1200wh 70w.
Most boondockers have between 200 to 400 amp hour battery banks.
This is also assuming of course you have a lot of battery power too.
We suggest a battery bank of 800 amp hours.
That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox.
You will need at least 1 800 watts of solar panels to run your rv air conditioner.
This is assuming you are considering using 12 volt rv grade panels.
The general rule of thumb is that a 100 watt solar panel can produce about 30 amp hours per day so you can use this guideline to determine about how many panels you need.
100 watt solar panel approximately 6 amps hour in direct summer sun no clouds here s an example of our calculation of how much the solar panels are generating to recharge our rv batteries.
Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.
This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv.
