Running A Full Sized Solar Panel On An Rv

24 hours a day we have refrigerated food and it is damn glorious.

Running a full sized solar panel on an rv.

This is the one that will control the amount of current that gets into the battery. Best expandable solar rv kit. The produced electric current is then fed into a charge controller. 7824 watt hrs day 160watts panel x 5 hours sunlight per day 9 78 10 panels.

I don t know too many people who rv under those conditions. The renogy solar panels came with short wires with mc4 connectors attached from the factory. If you are looking at this for an rv check out the rv solar panel guide as well use a solar calculator for a realistic estimate a solar power calculator will require some work on your end in terms of inputting what you want solar power for and looking at the wattage of your devices and appliances. For example to charge a 12v rv house battery you should pair it with a single 12v solar panel or multiple 12v panels wired in parallel.

It s called a controller because it modifies how much energy reaches the battery so as not to overcharge them. Rv solar panels work by converting sunlight into electricity or power. Besides the 8 batteries and 10 panels a couple adequate sized charge controllers and a smart battery charger would also be required for this example. 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.

How do rv solar panels work. Solar panel mc4 connectors connecting panels to combiner box. If you pair a pwm controller with solar panels that have a higher voltage than your battery the controller won t be able to use all of the current and will waste some of the generated electricity. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs.

For cable run lengths typical in rv applications we recommend 8 gauge for 10 amp systems 6 gauge wire for 30 amp systems 4 gauge wire for 40 amps systems and 2 gauge for 100a systems. Well folks those days are long behind us. As you can see operating a large refrigerator on just solar can become very expensive. Currently as we speak our self installed rv solar panels are completely running our new refrigerator.

Since the panels in our systems are always connected in parallel you can assume about 6 amps per 100 watts of solar panels. If running a solar system to power electrical items in your rv is new to you and you want to try it on a small scale this 12 volt kit is ideal. Remember back when we decided to rip out our rv refrigerator because it kicked the bucket and lived out of a cooler for a year. The panels create an electric current each time the sun hits them.
