A 300 amp hour camper battery for instance would need around 300 watts of solar power.

How many solar panels do you need to run a camper.

You ve already figured out how many amp hours of batteries you need from your solar power audit. If you have a rough idea of your power needs you need to check a solar panel s spec sheet and look for the watt rating the peak power amps and peak power volts. All solar panels serve a single purpose. 3 x 100 watt solar panels equals a 300 watt solar array how many watts of solar panels are needed to power a camper.

Solar panels we have four 100 watt polycrystalline panels installed on the front section of our camper s roof. To generate the stored electricity needed to run our rv air conditioner all day you d need over 340 square feet of solar panels ish plus 3600 amp hours of battery capacity and guaranteed perfect sunshine. This is assuming you are considering using 12 volt rv grade panels. Also keep in mind that solar panels experience a 75 90 drop in efficiency on cloudy days so it s good to have slightly more than you need when it comes to solar power about a 20 cushion if possible to account for less than ideal conditions.

They allow a user to harvest energy from the sun and turn it into electricity. Why are there types to choose from. Now that you are thinking in terms of the size of the solar panel array it s time to determine how many watts of solar panels you need. This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv.
