How many solar panels needed for rv.

What can you actually power with that kind of solar panel setup for your rv. This doesn t include the solar power needed to run anything else in the rv.

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. 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. Clearly this kind of setup can get pricey pretty quickly. Typically solar panels are usually just one of several energy sources that you ll find on the average rv.

If our 100w solar panel generates 70w every hour it will take a little over 17 hours to generate 1200wh 1200wh 70w. A modest travel trailer that draws 30 amps and doesn t have that many appliances is not going to need as many solar panels as say a 40 foot diesel pusher. 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. We would recommend 1 800 watts minimum.

We ll need about twelve 200 amp hour solar panels and one 100 amp hour panel to run the ac.
