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 do I size my campervan or RV solar setup?

Use this solar calculator to size your campervan or RV camper solar setup. If your device doesn't specify watts, use the watt calculator to convert amps and volts. List each device - every electrical component - its usage in watts, maximum number of hours used each day & if it's an AC or DC model.

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

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.
