Technical FAQs 4

Are solar panels good for RVs?

It’s become increasingly popular with campers, and especially RV travelers. Not only is it “Green” but modern solar panels are also efficient enough to reduce or sometimes eliminate an RV’s need for a traditional gasoline or diesel-powered generator. This might leave you wondering, just how much solar power do I need to power my RV?

How much solar power do you need for a camper battery?

A 300 amp-hour camper battery, for instance, would need around 300 watts of solar power. Also keep in mind that solar panels experience a 75-90% drop in efficiency on cloudy days, so it's good to have slightly more than you need when it comes to solar power (about a 20% cushion, if possible, to account for less-than-ideal conditions).

How much solar power does a motorhome need?

If you have a large Class A motorhome, your solar demand in a day might be as high as 240 to maybe even 360 amp-hours of power. Yet a smaller travel trailer, with modest appliances, energy-efficient LED lights, and mindful habits, might be able to live comfortably on 100 to 120 amp hours of green solar power.

How much solar power does a 15K BTU RV need?

Running AC on solar requires a substantial system. A 15K BTU unit needs 1,500W+ and would require 2,400W+ of panels plus 800Ah+ of LiFePO4 batteries for meaningful runtime. Many RVers use solar for everything except AC, running generators only for cooling. What happens during cloudy weather or winter?
