How Many Watt Solar Panel Do I Need For My Rv

You will need at least 1 800 watts of solar panels to run your rv air conditioner.

How many watt solar panel do i need for my rv.

This is also assuming of course you have a lot of battery power too. 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. This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. As we talked about above a 12v 100ah battery is 1200wh 12 100.

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. I don t see putting a 300 watt panel on the roof of an rv as very realistic. This is just a rough measure to get you in the ball park. A 400 amp hour battery bank will need roughly 400 watts of solar.

We can also think about it in watt hours. Most boondockers have between 200 to 400 amp hour battery banks. For our experiment 5 hours of direct sunlight without clouds x 6 amps generated per hour 30 amp hours per day that the solar panels are generating to. We suggest a battery bank of 800 amp hours.

Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day. This is assuming you are considering using 12 volt rv grade panels. What the sun will provide. You ll need to add up the total amp hours ah your batteries are capable of holding.

Simply put your maximum solar output in watts should equal your battery capacity in amp hours. And if you think there s the potential for damage it would be easier and cheaper to replace a single 100w panel than to toss an entire 300w one. If our 100w solar panel generates 70w every hour it will take a little over 17 hours to generate 1200wh 1200wh 70w. A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.

The number of solar panels needed for rv boondocking depends on how many batteries you have to keep charged. 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.
