How Many Watt Solar Panel Do I Need For My Rv

A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.

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

This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. We suggest a battery bank of 800 amp hours. 100 amp hours of useable power from a battery contains roughly 1280 watts of power 100ah x 12 8 volts 1280 watts of power the average hours of sunlight per day in the continental us is 6 hours. 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.

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. The number of solar panels needed for rv boondocking depends on how many batteries you have to keep charged. 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. How many solar panels do i need to run my air conditioner.

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. This is just a rough measure to get you in the ball park. Simply put your maximum solar output in watts should equal your battery capacity in amp hours.

As we talked about above a 12v 100ah battery is 1200wh 12 100. The more ah you have the more solar panels you ll need if you have a single 12 volt battery at about 100 ah you should have 300 watts of. How many watts of solar panels do i need to recharge my batteries. You ll need to add up the total amp hours ah your batteries are capable of holding.

We can also think about it in watt hours. This is also assuming of course you have a lot of battery power too. 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.

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. I don t see putting a 300 watt panel on the roof of an rv as very realistic. Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day.
