Adding Solar Power Panels to your Motorhome


The more time you want to spend in your RV, the more consideration you must give to power consumption. One solution is to install solar power, a power source that will for while you drive and camp in out-of-the-way places. To help you determine whether solar is right for you, Nohr’s RV Center compiled some helpful information on adding solar to your motorhome.




Going Off Grid

Most RV solar systems include a 3000-watt inverter to transform DC current into household current for ordinary appliances. Keep in mind that power inverters are not one-to-one transformers, and the more wattage being generated, the faster your DC source will be depleted. For best results, look into installing DC-powered appliances and low-power LED lights. Powering your motorhome home with DC current where its possible helps to reduce the requirements for your solar installation.


How Much Solar Do You Need?

The size of your solar system depends on what you are trying to accomplish. If you only want to keep your existing system charged between weekend trips, a small battery maintainer system is all you need. For powering the motorhome, you have to calculate the amount of energy you will need at any given time. In general, 400-800 watts of solar panels will power most RV requirements, scaling upward with RV size.


Storing Energy

Solar panels operate any time the sun is shining, including while you are driving down the road. Energy is stored in batteries, ranging from a bank of deep cycle batteries to battery systems designed specifically for mobile power storage. The more storage you have, the longer your system will operate at night or on rainy days, including appliances which run on inverted current. Around 300 amp hours of storage is fine for small RVs, but higher energy use may require 500Ah or more.


Heating Water

There are 12, 24, and 48-volt water heater elements available for solar power systems. If your motorhome is not already equipped with these DC systems, it would be a good idea to swap over. Heating water with traditional house current is faster and hotter, but it requires a lot of energy which is already losing efficiency by being inverted. Another idea is to install a solar water heater on top of the RV with a DC-powered circulating pump.

In most cases, there is plenty of room to mount solar panels on top of your RV. If you prefer, they are also available in portable frames that can be set up when you are parked.
