Off-grid living is very popular right now, but it’s not a fleeting trend.

It’s a really wise way to live, and living in an RV is probably one of the safest and most comfortable ways to go off the grid.

Being able to use adequate electricity without plugging into an outlet is the fundamental challenge of off-grid RV life.

Even the greatest deep cycle marine battery can’t keep your RV powered indefinitely.

But if you purchase mobile solar panel kits for RV usage, the situation can alter.

Since portable solar systems are far simpler to set up than permanent solar installations, they are very helpful for charging your RV batteries while dry camping.

Additionally, if you purchase a new RV or decide to sell your RV and move into an off-the-grid cottage, you may take them with you.

However, there are many different RV solar panel kits available.

For your benefit, we’ve examined the available options and selected seven of the top portable solar kits and panels for RV life.

How Can I Find The Best Portable Solar Kits And Panels For My RV?

However, how can you know which solar panel kit is ideal for your RV? It is crucial to comprehend the various kinds of panels and how they operate.

Additionally, you’ll want to learn more about the exact attributes and details of these panels so you can compare them more effectively.

All of it will be included in this buying guide.

Portable Solar Panel Types

Three fundamental criteria may be used to differentiate portable solar panels.

So let’s begin by identifying each and outlining the benefits and drawbacks of these three different kinds of solar panels.

#1. Single-Crystal Panels

The most known kind of panels are monocrystalline ones.

They resemble the well-known black panels that the majority of us undoubtedly connect with the harvesting of solar energy.

This kind of panel is very effective and produces a lot of electricity.

In comparison to other panels, they are less susceptible to high temperatures and are often the most lasting form.

However, because to their great power production and robustness, they are often the most costly solar panel on the market right now.

#2. Panes of Polycrystalline

The blue hue of polycrystalline panels is dotted or speckled in appearance.

Compared to monocrystalline panels, they are less expensive, but they are often less effective.

They also have a shorter lifetime than other panels since they are more susceptible to extreme temperatures.

#3. Solar Cells On A Thin Film

The most adaptable kind of solar panel, in my opinion, uses thin-film solar cells.

They are less expensive than monocrystalline and polycrystalline panels because they are simpler to make.

They further benefit from being flexible and the capacity to resist greater temperatures.

Since many RV roofs are curved, having additional installation choices is made possible by this flexibility.

These solar cells’ drawback, meanwhile, is that they often resemble crystalline panels in size and mass.

Additionally, they often have shorter lives.

How Much Solar Power Will My RV Need?

How much electricity do your solar panels need to produce, then? Whether you’re talking about installing solar panels on an RV or your whole house, this is the solar energy dilemma of the century.

However, let’s naturally concentrate on RV applications.

Whether solar energy will be your main source of energy or just a supplement, will determine how much electricity you need your panels to produce.

A 50 watt solar panel can be plenty if all you need it for is to gently trickle charge your RV batteries in case of emergency.

However, you may want more than one 200-watt panel if you intend to use your solar panels to directly power wall outlets and appliances.

However, the issue with this plan is that if you want to install a family of panels, you can find yourself fast out of roof space.

For comparison, some large RV air conditioners may need up to 3500 watts to turn on and 1500 watts per hour to maintain operation.

Since the biggest portable solar panels have a 200 watt output, starting an RV A/C unit of this magnitude would need more than 17 solar panels (excuse us while we do a little arithmetic).

Simply said, this is unfeasible for an RV with a small roof.

Additionally, it doesn’t take into consideration the possibility of concurrent use of other smaller appliances with your air conditioner.

There’s a good reason why a lot of RV generators can provide more than 30 amps.

On the other hand, portable solar panels seldom provide more than 10 amps.

The best solar panel installation for your RV requires careful consideration of your power requirements.

The best option is to utilize your solar panels to power your onboard 12-volt batteries and tiny gadgets.

Naturally, a bigger panel will be able to power up little gadgets and charge your battery more rapidly.

#1. Effortless Use (Include Portability)

The installation of any of these solar panel systems will need some understanding of fundamental electrical principles.

Nevertheless, some are far simpler than others, and you have to always choose a solar panel kit that includes detailed instructions.

Examining customer evaluations to see what others are saying about the installation of the panel is a fantastic approach to verify this.

We’re assuming that you’re interested in these portable solar panels because you want to be able to move them about since, after all, they’re portable solar panels.

You undoubtedly noticed that some of the evaluations looked more portable than others when you read through the ones up above.

If moving your panels is something you plan to do, make sure to take that into account.

The ease with which your panels will accomplish your goals also relies, well, on YOU.

For instance, a kit without a transfer switch would not be as simple to operate if you want to utilize solar panels to meet your RV’s daily power demands.

The switch must be bought individually, and you must choose the best way to install it.

This is but one possible instance in which an RV solar panel kit that first seemed appealing could not fulfill your expectations.

In order to choose a product that will be simple for you to operate, make sure you are aware of your power requirements and the precise way you want to utilize your panels.

We do advise hiring a professional if you are at all uneasy about installing your solar panels since electricity is involved.

On this front, it’s better to be safe than sorry, and it’s always a good idea to hire a professional if you don’t know the distinction between positive and negative terminals, how to connect fuses, where your inverter should connect, or any other crucial details of putting together a solar installation.

#2. Durability

The good news is that roof-mounted solar panels often tend to be less resilient than portable solar panels.

This is due to the fact that they were created to be moved about and linked and unplugged regularly.

But based on the materials used in their production, many portable panels are more or less robust.

Make careful to consider the quality of all parts, not just the panels themselves, when evaluating the longevity of a certain panel or solar system.

The wires, frame (if applicable), clamps, connections, and other accessories are included in this.

As with any other exterior RV equipment, such as roof antennae and tire pressure monitoring systems, durability in solar panels is crucial (TPMS).

#3. Operating Temperature Optimal

Your solar panels’ ability to collect energy is only as good as your battery’s capacity to store it, unless you’ve installed a transfer switch that enables your solar panels to deliver direct electricity to your RV’s outlets and appliances.

The ambient temperature might also have a direct influence on battery capacity.

In general, RV batteries don’t like to become too hot.

In fact, every time the temperature climbs by 15 degrees Fahrenheit, a battery’s life will be halved.

Interestingly, with the same temperature increase, storage capacity will also rise by 10%.

On the other hand, a battery’s lifetime actually increases in colder climates.

But a battery’s storage capacity is decreased by 10% for every 15 degrees (still in Fahrenheit) of temperature drop.

Less storage capacity translates to less energy available for usage between solar charges.

This is significant when evaluating how fast a certain solar panel can recharge your batteries.

Additionally, there are ideal working temperatures for solar panels.

It’s always a good idea to check the rating to make sure it will function well in the temperature range where you spend the most of your time in your RV, even though most are certified to perform properly at most temperatures, except for the very extremes.

Stages of Solar Charge

Charge controllers are installed in many of the panels we’ve described.

There are three broad phases that panels go through while they are charging and the charge controller is working correctly.

Bulk charge, absorption charge, and float charge are the names of these three phases, respectively.

#1. Large Charge

Bulk charge is the phase in which your RV battery is charged using all of the panels’ available electricity (or batteries).

Until the absorption voltage is achieved (usually 14.4 to 14.6 volts), the bulk charging step will often continue.

#2. Absorptive Cost

Once the predetermined absorption voltage is obtained, the absorption charge step starts.

Your RV battery is typically at 85% of its full charge capacity at this stage.

The controller will now attempt to maintain that specified absorption voltage for a certain amount of time in order to prevent overcharging.

The absorption voltage and time duration of a controller are often pre-programmed by the manufacturer, and this is typically one or two hours.

You may alter these settings on certain controllers as well.

#3. Charge Float

After the absorption charge phase is over, the float charge stage starts (i.e.

the programmed time period in the controller passes).

By this time, your batteries should be almost completely charged, thus your controller will actually reduce the battery charge voltage to a range of 13.2 to 13.7 volts.

Once again, the precise figure will be determined by the manufacturer.

As long as the sun is still shining on your solar panels, it will then maintain this lower voltage.

It prevents overcharging of the batteries and boiling off of the battery acid by maintaining this lower voltage.

Optional Mounting

Thankfully, the majority of solar panels come equipped with all of the brackets and adapters needed for installation.

However, if this isn’t the case, you should be aware of the additional materials you’ll need when you buy your panels.

Of course, installation won’t be a problem if all you want to do is leave your portable panels lying about throughout the day.

To make sure you have a mounting option that works with your RV layout, you still need to be aware of your mounting alternatives before buying a solar panel kit.

Which of the Best RV Portable Solar Panels Is Right For You?

Since this RV solar kit is especially designed to make it simple for individuals with very little solar knowledge, Renogy MPPT-Rover40 Solar Starter Kit is our choice for the finest portable solar panels overall.

The controller that comes with it enables you to extend the system for even more capacity, and it is also rated to provide the most wattage of any panel on our list.

However, we strongly advise taking a look at the Renogy Flexible Monocrystalline Solar Panel if you’re searching for a backup plan.

This panel has great waterproof qualities, which we believe you’ll like, and we love how versatile it is.

One of the better solutions for flexible solar panels that can be installed on curved roofs or other challenging surfaces.


If you know the basics of electrical circuits, they are really pretty easy to grasp.

But if you’ve never used them before, they could seem complicated.

So let’s fill up your figurative “electrical tool kit” by addressing some crucial inquiries concerning solar panels and their use.

How much energy do I require?

The answer to this issue will mainly depend on whether you want solar panels to only top up your battery charge or whether you’re seeking for a bigger system that can provide your RV with all of its daily power requirements.

Before choosing a panel, you should assess your unique power requirements.

The typical individual panel has a maximum output of 200 watts.

Where should my panels be installed?

The purpose of portable panels is to be put or set up wherever it is most practical for best solar exposure.

However, the most typical place to put this kind of panel is on your RV’s roof.

Of course, doing so will demand that you park your vehicle in a way that allows the bulk of the day’s direct sunshine to strike your roof.

Understanding how many hours of direct sunshine solar panels need to operate at their peak efficiency may help you choose your installation location more wisely.

Make sure you have enough wire to extend from the panels to your RV batteries if you decide to just mount your panels anywhere on the side of your vehicle.

Keep in mind that less power will go from the panels to your battery when the wire is longer.

Therefore, if you want to get the most out of your solar panels, it’s a good idea to position them as near to your battery as you can.

Does my arrangement need additional components than simply the panels?

Here, the quick response is “yes” You will need wires, at the absolute least, to connect your panels to your battery.

Additionally, you may need to make a fresh investment in your battery if it isn’t compatible with the panels you wish to purchase.

Again, it will depend on how you want to set up and operate your panel arrangement if any further purchases are required.

You may need to buy an extra deep cycle marine battery if you want to buy a sizable number of panels to collect more watts in order to boost your energy storage capability.

A solar charge controller may also be needed for this, which will stop your batteries from being overcharged.

This is required because some panels generate voltage that is far greater than what batteries are designed to store.

Additionally, an inverter and/or a transfer switch are definitely required if you want to utilize your solar panels to meet your RV’s daily power requirements.

An inverter’s function is to convert direct current (DC) into alternating current (AC).

Normally, the batteries that your solar panel charges will create DC, but if you want your RV to fully work off-grid, you’ll need an inverter that can give AC to your outlets and other appliances that need it.

With the use of a transfer switch, solar panels will be able to power your RV’s outlets without first charging the batteries.

This is helpful if you want to utilize solar energy to meet your daily power demands, but it can need more initial electrical wire installation.

Should I choose roof-mounted or portable panels?

Depending on how much power you need, this may vary.

It’s vital to remember that the majority of portable solar panels nowadays have a 200 watt maximum output.

So if you want to use solar energy to power your full 40-foot RV, you could need quite a number of them.

If so, you may think about putting in a few roof-mounted solar panels in addition to having a portable panel available for additional solar collecting and flexibility to sun conditions.

However, you most likely don’t have enough roof space for bigger roof-mounted panels if you’re attempting to utilize solar power for a tiny camper van, for instance.

Therefore, depending on your urgent demands, you’ll need the kind of movable panels that may be put and removed more often.

So let’s attempt a more brief summary.

We advise using roof-mounted solar panels if you’re a full-time RVer who wants to use solar energy to power your whole vehicle.

Portable solar panels, however, are the ideal choice if you have a smaller setup and want more flexibility in how your panels are put up.

Is it crucial what kind of batteries my RV already has?

Yes! To choose solar panels that work with your RV’s present batteries, you must be aware of their voltage and amp-hour ratings.

The majority of RV batteries are either 12-volt or 6-volt batteries, however there is greater variance in each battery’s amp-hour rating.

It’s crucial to understand that the amp-hour rating shown in the battery’s specs is tested at a specified temperature, which is often about 77 degrees
Fahrenheit, when evaluating the storage capacity of your current RV batteries.

The outside air temperature, as we discussed in greater detail in the Optimal Operating Temperature section above, will have an impact on the amp-hour rating.

However, it bears repeating that the outside air’s temperature will have a direct impact on a battery’s capacity.

Additionally, you now understand why so many RVers seek for warm climates.


You can camp in more isolated locations and remain off the grid for longer if you purchase portable solar panels.

The beautiful thing about utilizing them for an RV is that you can carefully position your rig so your panels get the greatest solar exposure.

They’re obviously ideal for regions that get considerable direct sunshine for numerous hours every day.

As someone who has nearly completely lived off the grid in an RV, I can attest that purchasing solar panels up front would have undoubtedly decreased my yearly power expenses.

Therefore, you should certainly invest upfront in high-quality portable solar panels if you have long-term intentions for your RV.
