The Best Solar Panels for RV: Which is Better to Choose

The Best Solar Panels for RV Which is Better to Choose

Solar panels for RVs operate in the same way as solar panels for homes and businesses, but on a smaller, more portable scale. The light coming from the Sun is captured by the solar panels and converted into electricity that can be used for the RVs. It can then be utilized to run the RV’s outlets, lights, and appliances.

If the RV does not have solar panels, it will have to use a generator or a campsite hookup to get the electricity. RV solar panels, which rely on renewable energy, offer a practical and eco-friendly replacement for these conventional sources.


Like a typical residential solar system, an RV’s solar panels turn sunshine into electricity. With the exception that they recharge the RV’s batteries rather than powering the home.

Additionally, additional batteries can be purchased that can be recharged by the solar panels, generating more amount of electricity.

Four key parts make up an RV solar panel system:

  1. solar energy systems that produce electricity from sunlight,
  2. a charge controller that prevents overcharging of your battery,
  3. an inverter to transform solar electricity from DC to useable AC and
  4. a battery for electricity storage.

Are RV solar panels necessary?

People can use solar electricity in RVs effectively in some circumstances. In some cases, it does not make as much sense. For those who primarily camp at established campgrounds where electric hookups are provided as part of the campsite fee, solar power is not a viable option.

Despite being incredibly cool, solar panels are pricey. To ensure that your estimates of the expenses and advantages associated with solar are accurate, you need to conduct some in-depth study and calculations.

People who enjoy camping in remote areas without access to utilities may find solar power to be an incredibly wise choice. You must be self-sufficient when camping, and solar power can increase the amount of time you can spend outside.

Simply conduct yourself as you normally would while camping, and after 24 hours, check your battery level. This can help you estimate how much energy you consume on an average day.

What exactly do you need solar panels for if you often go 2 or 3 days without recharging your batteries and you seldom truly go camping for more than 2 or 3 days? Purchasing solar panels might not be a good idea in this circumstance.

How many RV solar panels are required?

RV solar systems typically offer a less powerful output than residential and commercial solar systems, through which an entire home or establishment can be powered. Since fewer lights and appliances are used in an RV than they would be in a traditional house, this normally does not pose a problem.

The number of solar panels required for an RV depends on several elements, such as your energy usage patterns, the effectiveness of the solar panels, and the quantity of daily sunlight your house receives.

Cost of RV solar panels

Depending on what is required from the solar system, one can spend as much as he or she likes on solar panels for the RV. If more electricity is required, more equipment is to be bought. It will increase the overall cost of the RV solar system.

The price range of RV solar panel kits is from $100 to $1,000 and even more. The requirement for energy determines it. On the other hand, the cost of an RV solar panel starter package is between $200 and $500.

When you are initially starting with solar, kits in this price range are a wonderful place to start because they often contain a charge controller, solar wires, and one or two solar panels. However, a generator will still be necessary to augment your usage.

Installation and maintenance

It is time to install the appropriate solar panels for your RV once you have found and acquired them. Thankfully, setting up RV solar panels is simple and should not require a specialist.

Solar panels that you have purchased and need to be placed on the roof ought to have installation instructions. Usually, this only necessitates a few simple things, like attaching the RV with the panels using the brackets. The amorphous solar panels come up with an adhesive backing that can be can rapidly attached to the roof, and are even simpler to install.

Once the system is operational, maintenance should be comparatively low. With solar energy, the tension of purchasing fuel would be reduced as a generator powered from sunlight would be used. In addition, the warranties of RV solar panels are long-term (often 25 years), assuring that the purchase is a wise one.

What to consider when buying RV solar panels?

Buying RV solar panels requires the consideration of the following key things.

  • Power consumption

Determine how much power would be used while camping to determine which solar panels will work best for the RV. In such case, the number of solar panels and any additional batteries that would be required must be calculated.

The average RV camper uses 20 kWh of electricity each day. It will require more solar panels because of the increased electricity consumption as more appliances are added. However, two or three solar panels will typically be able to provide enough energy to power most of the small appliances. In case, heavy equipment like a refrigerator or air conditioner are to be powered, a generator or more panels and batteries would be required.

It is okay if the exact amount of power the RV consumes is not known. In such case, always buy a cheap RV solar kit and test it out to see if it works for the RV or not. The system can then be expanded if additional panels or batteries are required.

  • Batteries

If the aim is to store the energy being generated from the Sun, then there is a need to purchase some extra battery banks. Most RV users select 12V batteries. For an RV, either lead-acid batteries or lithium-ion batteries can be chosen, but each has advantages and disadvantages of its own.

The most typical type of battery used by RV campers is a lead-acid battery. They are so well-liked because they are affordable and strong. However, they often need to be changed after five years and based on the kind of lead acid battery being used, it can need routine upkeep.

Lead acid batteries outperform the lithium-ion batteries in terms of cost. They are more effective, endure longer, and store more energy. Lithium-ion batteries are pricey, but they are well worth it for folks that boondock full-time.

  • Size measurements

Because of their exposure to those vital sunrays, RV solar panels are typically put on the roof of your vehicle. RV users should consider panel size while selecting their optimal solar panels considering this location.

Finding panels with the right measurements helps maximize the area on your roof. To make sure you are buying equipment suitable for your scenario, it is advised to use the dimensions of your roof as a guide.

It is also important to keep in mind that solar panels will have to share roof space with other equipment, such as an antenna or air conditioner. When making this choice, you should also consider these pieces of equipment.

  • Construction

You will need to install the solar panels for them to give your rig usable power, so choosing the appropriate ones is only half the battle. Without a panel made of lightweight material, this technique can prove to be laborious.

As a result, to make sure its installation is not difficult, I would advise selecting panels that are on the lighter side. But just make sure that these lightweight choices are nonetheless trustworthy and robust. Some companies solely care about reducing the weight of their products at the expense of durability.

These thin panels will prevent the chassis of your equipment from being overburdened. It is just a quick and easy technique to make sure your new gadgets do not create more problems than they solve.

  • Solar panel types

Solar panels come in three primary varieties: monocrystalline, polycrystalline, and amorphous. The most effective and costly materials are monocrystalline. Monocrystalline panels are unquestionably the ones for you if your space is restricted. Although slightly more expensive than monocrystalline panels, polycrystalline panels are marginally less effective.

Flexible thin-film solar panels are known as amorphous solar panels. They are the least expensive alternative, but they are also the least effective. To create anything, like what monocrystalline or polycrystalline panels produce, you would need more of them. Additionally, they must be glued directly onto the top of your RV to be fitted, which might damage the roof and make removal challenging.
