Most solar panels feature one hundred watts of power and are capable of producing about six amps for each peak sun hour.

How many solar panels for motorhome.

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 is assuming you are considering using 12 volt rv grade panels. If you have an 800w rv solar panel system that is in direct sunlight for 5 hours a day you ll produce approximately 4 000 wh of energy each day 5 x 800 4 000. A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.

This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. Most boondockers have between 200 to 400 amp hour battery banks. Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day. According to our calculations in the table above that s more than enough to power small devices like lights and tvs but you won t be able to run a refrigerator for an entire.

You will need at least 1 800 watts of solar panels to run your rv air conditioner. We suggest a battery bank of 800 amp hours. 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. 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.

What the sun will provide.
