How Many Solar Panels For Motorhome

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.

How many solar panels for motorhome.

A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. 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. 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.

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

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. This is also assuming of course you have a lot of battery power too. 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. Most boondockers have between 200 to 400 amp hour battery banks.

We suggest a battery bank of 800 amp hours.
