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.

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

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. This is assuming you are considering using 12 volt rv grade panels. 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. We suggest a battery bank of 800 amp 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. You will need at least 1 800 watts of solar panels to run your rv air conditioner. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.

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.
