How many solar panels for rv.

Basic parts of an rv solar power system. 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. 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. Typically solar panels are usually just one of several energy sources that you ll find on the average rv.

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. 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. Boondoctor will mount 1 400 watts of residential grade solar panels on the roof.

A 400 watt starter kit suitable for the roof of a standard rv might consist of four solar panels with wiring and an attached controller. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. Solar energy for an rv can come in a number of configurations particularly if you are a do it yourselfer. A 100 watt solar panel produces approximately 6 amps per hour in direct summer sun without clouds.

Assuming we get 5 hours of direct sunlight we know a 100 watt solar panel will produce 30 amp hours per day. These are 24 volt panels as opposed to typical 12 volt rv panels. Obviously the answer will depend on the size of your rv and how much electric power you re trying to generate.
