How Many Watt Solar Panel Do I Need For Rv

Tips for estimating rv solar panel needs although actual output may vary based on the factors mentioned above you can get yourself to a ballpark figure using a couple of tips.

How many watt solar panel do i need for rv.

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. This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. You will need at least 1 800 watts of solar panels to run your rv air conditioner. 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.

If you have a rough idea of your power needs you need to check a solar panel s spec sheet and look for the watt rating the peak power amps and peak power volts. We suggest a battery bank of 800 amp hours. This is assuming you are considering using 12 volt rv grade panels. As we talked about above a 12v 100ah battery is 1200wh 12 100.

100 watt portable solar panel. Most boondockers have between 200 to 400 amp hour battery banks. 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. If our 100w solar panel generates 70w every hour it will take a little over 17 hours to generate 1200wh 1200wh 70w.

5 hours of direct sunlight x 6 amps generated hour 30 amp hours day.
