How Many Solar Panels Needed For Rv A X

5 hours of direct sunlight x 6 amps generated hour 30 amp hours day.

How many solar panels needed for rv a x. So you are going to need a total wattage of 300 combined solar panels. This doesn t include the solar power needed to run anything else in the rv. We ll need about twelve 200 amp hour solar panels and one 100 amp hour panel to run the ac. Lastly you will need the solar panels to keep the battery charged.

100 watt solar panel approximately 6 amps hour in direct summer sun no clouds here s an example of our calculation of how much the solar panels are generating to recharge our rv batteries. This is also assuming of course you have a lot of battery power too. If you use 250w panels you need 27 of them. You ll need to add up the total amp hours ah your batteries are capable of holding.

Most boondockers have between 200 to 400 amp hour battery banks. The more ah you have the more solar panels you ll need if you have a single 12 volt battery at about 100 ah you should have 300 watts of solar panels minimum. Reality is you only need as many panels as your batteries are able to store and your usage warrants. However you can use the same procedure to estimate how many are needed.

How did i come up with 300. 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 assuming you are considering using 12 volt rv grade panels. We suggest a battery bank of 800 amp hours. 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. You multiply the combined wattage of the solar panels by the number of hours sunlight.

On the other hand if they are 330w panels only 21 are needed. 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. 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. The number of solar panels needed for rv boondocking depends on how many batteries you have to keep charged.
