Use solar power
Solar panels are a great way to power your RV, especially if you want to try dry camping or boondocking. They are also a good option if you want to reduce your carbon footprint and camp in areas where it is difficult to use a generator.
Solar panels capture sunlight and convert it into usable electricity. The number of solar panels you will need depends on your power consumption habits, the efficiency of the panels, and the hours of sunlight your RV receives. Before purchasing solar panels, you should determine your RV's power needs. Make a list of the appliances you will be using, how much power they need, and the number of hours you will be using them each day.
