How Many Solar Panels For Motorhome

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.

How many solar panels for motorhome.

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 is assuming you are considering using 12 volt rv grade panels. Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day. A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.

We suggest a battery bank of 800 amp hours. 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 also assuming of course you have a lot of battery power too. 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.

Most boondockers have between 200 to 400 amp hour battery banks. This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. 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.
