How to RV the Earth-Friendly Way

Go Solar

A solar system will convert energy from the sun to electricity for your RV, storing any extra electricity in your RV's batteries. According to the Recreational Vehicle Industry Association, at least 15% of RV owners are already using solar panels.

To figure out how many solar panels you'll need, figure out how many amp hours you typically use. Start by figuring out your appliances' current via its label, an ammeter or this helpful worksheet. Multiply the appliance's current by the number of hours the appliance is in use each day. Total the amp hours of all your appliances to find your total daily energy consumption. Then, use this RV solar calculator to determine the number of solar panels you will need.

A 10-watt solar system will produce 0.6 amps of charge power for about $145. A 110-watt solar system ($683 from Alter Systems) typically produces about 275 amp hours per week. All RV solar systems are modular, so you can add new panels as you need them.

Increase your RV's energy efficiency just as you would a stationary home. Seal drafts, beef up your insulation and use Energy Star appliances. And increase your RV's fuel efficiency the same way you would with any vehicle: Make sure your tires are optimally inflated and drive the speed limit.
