How much solar power does my RV need?

The best rule of thumb is about 100 watts per 30 amp-hours each day, but there’s more to it than just putting enough panels up. Read on to learn just how much solar power your RV needs depending on what you operate, how efficient your panels are, and more.

How many Watts Does It take to power an RV?

Typically, a small RV with minimal electrical appliances may need as little as 100W, while a large RV with air conditioning may benefit from 1000W. How much space will I need on my RV for solar panels?

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 do I calculate my RV solar power needs?

The first step to calculate your RV solar power needs is to sit down and in your head, go through an average day. Think about all the electric-powered things you use, and make a list. A spreadsheet would be a good place to make this list because it will be easy to add up the total and handy to reference later.
