by John Brown | Last Updated: 05/18/2017

Using a solar panel system is an inexpensive and efficient way to use the sun’s rays. There are many systems available, and some of them are big enough to provide power for a building. The batteries used on these systems are just like those used to power your car. Portable solar panels are an excellent way to get your car’s engine started if you wake up one morning only to find out that you left the lights on before going to bed and your battery died many hours ago. Today we will be reviewing some of the best portable solar panels for RV and other cars.

Best Portable Solar Panels for RV Additional Info

In simple terms, these portable solar panels for RV consist of one or more panels that transform the energy received from the sun into electricity. Each solar panel consists of two layers of silicon slices with a pathway in between. Light from the sun hits the electrons on the top layer and makes them move to the bottom one. As they do this, they create a current. The pathways formed in the solar panels guide these electrons from one layer to the other.

Types of solar panel systems

There are several ways to set up a solar power system. The first one is called a grid-tied or inverter system. Any energy received from the solar panels is immediately converted into usable energy. This is done by using an inverter, which converts the DC power from the panels into usable AC power since electric appliances in the US need 120v to work.

The problem with these systems is that they require an inverter, which isn’t exactly an inexpensive device. It is also more dangerous. Playing around with 120v electricity can be very risky if you don’t know what you are doing. Since the power from the panel is sent directly to the inverter, there is not much protection in case there is an overload, so it is always wise to add a circuit breaker to the layout.

Another type of solar system set up is called off-grid, which is the most popular. It is meant to be as portable as possible so it can be carried around, or installed on cars, boats or RVs. Instead of directly using the panel’s power output, any generated electricity is sent to one or more batteries, where it is stored and used as needed.

This is done by sending the electricity from the solar panels to a charge controller, which sends a regulated, stable 12v output to the batteries to charge them. It also stops the battery from being overcharged and from running completely flat. Some charge controllers have temperature sensors that shut off the system if things get too hot. A charge controller can also send a direct DC output, so you can connect any 12v device to it and use the solar panel’s output on demand without relying on batteries.
