How many solar panels for motorhome.

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. This is assuming you are considering using 12 volt rv grade panels.

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