How Much Does It Cost to Install Solar Panels on an RV

Remember that prices will vary based on the brands and the time of the year, so make sure to check everything before deciding to purchase. Here’s a cost breakdown of how much does it cost to install solar panels on an RV:

1. Small Rooftop RV Solar System

It is the lowest-capacity solar panel for an RV, but still suitable for off-the-grid camping in a small camper. This package contains a solar battery charger and a 110 volt AC power component provided by an inverter.

The installation of this type of solar system is not tough at all. Use heavy-duty cables to connect the inverter to the batteries. Now, you have to run a power strip from the inverter to anywhere inside the rig.

Plugging the AC appliances into the power strip is a better idea than taking power from the wall outlets. Be careful about not putting much pressure on the inverter by operating too many things simultaneously.

Small Solar Panel Kit and Price

If you are willing to purchase an RV solar panel package of 150 Watts, it will cost you around $430 to $440.

You can extend the package by adding another solar panel of 300 or 450 Watts and with a big-size charge controller. The package will include these items:

  • A solar panel of 150 Watts
  • Mounting brackets
  • Charge controller
  • Modified sine wave inverter
  • Cables and connectors
  • Heavy-duty cables
  • Power strip

2. Portable Solar Power Folding Suitcase

A portable solar power package, which you can fold like a suitcase, is a popular option for the weekenders and seasonal RVers. As you can join the parts together, it is easy to fold them for carrying or storing like a suitcase.

It is also a convenient alternative for the boondockers who are not comfortable handling the electrical things. The self-contained nature of this solar panel works as its plus point.

If you sell your present trailer and get a new one, you can fit the same solar panel to your new RV. Or, you can sell the solar panel too with the RV and install a roof-mounted solar system later.

Should You Invest in a Solar System for RV?

After getting an idea about how much does it cost to install solar panels on an RV, you must be thinking whether to invest in this power system. Think about these points before making the purchase:

  • When you stay in campgrounds and parks with hookups, you don’t need a complete solar system.
  • If you are out in your RV on during the weekends or holidays, or a limited time, a complete RV solar system will be a financial loss. Instead, you can opt for a smaller solar system of 100 Watts.
  • If you are a boondocker who camps or parks in places without an electrical facility, you need a complete RV solar system. Spending on a package that includes solar panels, a battery, charge controller, and the inverter will turn out to be useful in the long run.
