What is an RV Solar Panel?
A solar panel is referred to as a device responsible for converting sunlight into electricity. It is an incredibly useful investment for RV owners since they provide electricity (solar power) wherever they are. Though the solar panels installation process is time-consuming, it is extremely beneficial in the long-run because they can provide free power and energy.
If you love dry camping or go off the grid, then making sure that you have a solar panel with you can help you a lot.
It also reduces energy consumption, that too, without requiring much on your part. All that’s required to make panels work is sunlight. You can run all of your onboard appliances without anything but the sun’s rays.
You’ll have peace of mind as you no longer required running the generator, which produces a lot of noise. Aside from being noiseless, it is also environment-friendly. However, it costs you a significant amount to set your RV solar panel.
How Does RV Solar Panel Work?
An RV solar panel is responsible for providing solar power. You need to invest in a few of them to efficiently run the electric appliances in your recreational vehicle through solar power. The first step is to mount the solar panel on your recreational vehicle’s roof.
The number of RV solar panels you need entirely depends on your power requirements. Once installed, the solar panel will start working by transforming the sunlight into power/electricity. The power they generate will then go to the wires that link all the solar panels together.
The power will then be transmitted down to your vehicle. However, before feeding your vehicle with solar power, the entire process has to make some stops. The first stop is the charge controller. It is a device responsible for transmitting the power created by the panels to your RV’s battery system.
With the charge controller’s help, it is easy to regulate the power received by your vehicle batteries, which helps prevent overcharging. It also helps to preserve the functionality and longevity of your batteries.
Once the created power is transmitted into the charge controller or battery charger, it is ready for use. However, remember that the power already stored in your vehicle’s battery bank is still the DC power.
Types of RV Solar Panels
Before you invest in an RV solar panel available on the market today, make sure to know about their types and how each one work. Below, I have bucketed different types of solar panels for RV battery charging and some details about each one:
1. Polycrystalline Solar Panels
Polycrystalline solar panels contain small solar crystals taken from numerous blocks of silicon. These types of solar panels are incredibly popular among RV owners. Though the energy these panels generate is less than what monocrystalline panels produce, they are still a good pick as the loss of power is easier to neglect.
2. Monocrystalline Solar Panels
These solar panels contain a single large silicon crystal. Most people consider these as the most effective solar panels because they yield a high charge output. They can also produce and supply a greater amount of power when being used in low conditions.
3. Amorphous (Thin-Film Solar Panels)
These types of solar panels are constructed by laying silicon on a large bed. The good thing about these solar panels for RV is they are cost-effective to make. However, amorphous solar panels generate the lowest amount of power out of all three.
Moreover, while these solar panels work well, they need more roof space than the other two solar panels to provide the same energy.
Benefits of Solar Panels for RV Battery Charging
For RV owners, solar panels are cost-effective and provide consistent energy when traveling off the grid. Here are the advantages that you will enjoy if you installed the RV solar panels in your vehicle:
1. Effective in Charging House Batteries
One advantage of solar energy generated by solar panels is they supply a slow and steady charge to your battery bank. It is a useful and natural way to keep your batteries charged while also extending your battery’s life.
2. They Provide Electrical Power
Having solar panels installed in your RV ensures that you get an uninterrupted and consistent electric power supply. It is possible, regardless of how remote your present location is. Moreover, it also enables you to lessen your worries when enjoying breathtaking views in a new location. They are essential to have because they provide power in emergency circumstances.
3. Noise-Free and Environment Friendly
Another benefit of solar panels for RV battery is they are clean, do not cause air pollution, and noise-free. It makes them easy and safe to use. They do not need any fuel and do not emit waste as well. With that, you’ve got the assurance that the solar panels are clean and safe for the environment.
Furthermore, RV solar panels don’t have any moving parts, so they do not produce any mechanical noise. They are easy to use, and you just need to place your vehicle under the sun to create power.
4. Extends the Life of Your RV Batteries
Solar panels for RV batteries are also great for extending the lifespan of your vehicle batteries. It is because they create pure DC power when being exposed to sunlight. This is what your vehicle batteries want. Moreover, they also help you reduce the threat of deep discharge by steadily and slowly providing power to your batteries.
There you go – top 5 best solar panels for RV battery charging. By installing the best solar panels for RV battery charging, you will be able to enjoy a free and abundant power source. They are great, especially if you like dry camping or traveling off the grid. I would like to thank you for reading this review guide.
