The Unfortunate Truth About RVs With Solar Panels

How Do Solar Panels Work?

Solar panels are made up of photovoltaic cells that convert sunlight into electricity. When sunlight hits the cells, it causes electrons to be knocked loose from their atoms. These free electrons are then captured by the cells and sent through a circuit, where they are converted into usable electricity.

Solar panels are typically made from silicon, which is a semi-conductive material that allows electricity to flow through it. The efficiency of a solar panel is determined by how well it can convert sunlight into electricity, and this is typically measured in terms of watts.

The True Cost of Solar Panels

One of the biggest drawbacks of RV solar power is the cost. Solar panels are not cheap, and the cost of installation can vary significantly depending on the size and complexity of your setup. You have to consider size as I would definitely not want a solar kit that is under-powered.

To give you an idea of what you can expect to pay, here are some rough estimates for the cost of solar panel installations:

• A small, basic solar panel system for an RV might cost around $1,000 - $2,000. This would typically include a single panel, a charge controller, and a deep cycle battery.

• A mid-sized solar panel system for an RV might cost around $3,000 - $5,000. This would typically include two to four panels, a charge controller, and a deep cycle battery.

• A large, high-end solar panel system for an RV might cost $6,000 or more. This would typically include four or more panels, a charge controller, and a deep cycle battery.

It's noting that these estimates do not include the cost of labor, which can add significantly to the overall cost of installation. In addition, you'll need to factor in the cost of maintenance and repairs over time, as solar panels and other components can fail or wear out.

Is Solar Power It?

Whether or not solar power is it for your RV will depend on a number of factors, including your budget, energy needs, and how you plan to use your RV. Here are a few things to consider:
