How Many Solar Panels For Motorhome

This is also assuming of course you have a lot of battery power too.

How many solar panels for motorhome.

Most solar panels feature one hundred watts of power and are capable of producing about six amps for each peak sun hour. A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds. What the sun will provide. Most boondockers have between 200 to 400 amp hour battery banks.

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. 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. 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.

This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. This is assuming you are considering using 12 volt rv grade panels. 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. 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.

Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day.
