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 to install a solar power system on a motorhome?

To properly install a solar power system on a motorhome, it is essential to comprehend its energy needs. This means calculating the energy used, the solar panels needed, and the battery storage options. When estimating power needs, RV owners should consider their appliances’ wattage and usage.

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 travel trailer need?

An average travel trailer need 120 Amp Hours of solar power, whereas a luxury fifth wheel or Class A motorhome might need 240 to 360 Amp Hours of solar power to truly maintain its arsenal of appliances and creature comforts. So, this wide range will influence just how long it takes for you to see a full return on your initial investment.
