5 Best Portable Solar Panels for Your RV

5 Best Portable Solar Panels for Your RV

One of the chief reasons why we can boondock (camp off-grid) for as long as we do is the ability of our substantial solar array to harness the awesome power of the sun to keep our electrical system running wherever we are. But we’re full-timers (and we’ve been so for very nearly two decades) and we live and work on the road from our RV, so we need lots of power. Not everyone needs a massive solar array with multiple solar panels and a panel tilting system installed on the roof of their rig, and not everyone is interested in the time, effort, and expense needed to install a setup like ours. Fortunately, there are portable solar panels for RVs now, and the technology behind these panels has improved tremendously.

This means that keeping your RV battery bank charged and using the power of the sun to tend to your electrical needs when you’re camping off the grid has never been easier.

In today’s post, we’re taking an in-depth look at portable solar panels. What exactly are they and how do they work? Can you toss a couple of portable solar panels in your RV and power your rig with the sun when you reach your destination? It’s not quite that simple, but close!

Let’s dig into the ins & outs and the pros & cons of portable solar panels for RVs.

What Is a Portable RV Solar Panel?

Portable solar panels are carried inside your RV while you’re traveling and can be set outside in the sun when you’re camping.

A portable RV solar panel is very similar to a solar panel you see installed on the roof of an RV except that it’s able to be moved from place to place, and is stored in your RV for travel and when not in use.

Portable RV solar panels usually have MC4 connectors (or similar) which allow them to be very easily connected to a charge controller… which is in turn connected to your RV’s 12V house battery/battery bank (often by large alligator clamps, like for automotive jumper cables).

Like mounted solar panels, a portable RV solar panel may be polycrystalline or monocrystalline.

Polycrystalline vs. Monocrystalline Solar Panels

Polycrystalline panels can be identified by their lighter blue color. The process used to make polycrystalline silicon is a simpler process, making these panels less costly to produce, and thus less expensive to buy. However, they’re also slightly less efficient than monocrystalline solar panels.

Monocrystalline panels can be identified by their darker blue/black color. These panels are not only more efficient at generating power, but (as a result) more space-efficient because they’re smaller. Monocrystalline panels are more expensive than polycrystalline panels.

What Are the Advantages of Portable Solar Panels For RVs?

There are a number of advantages to using portable solar panels for RVs. Let’s take a look at some of their benefits.

No Installation

Portable solar panels for RV don't require you to get up on the roof.

With portable solar panels, there’s no need to get up on the roof of your rig for installation or cleaning purposes.

There’s no installation necessary with a portable solar panel. No holes need to be drilled into the roof of your RV for mounting hardware or to run cords through to the charge controller. No need to even get up on the roof at all.

Portable RV panels don’t need to be installed – they simply need to be placed in the sun and connected.


One of the great benefits of portable RV solar panels is the fact that they can be moved to wherever the sun’s light is most prominent. When the sun moves, the panels can be easily moved to follow it to continue to best capture the power of the sun.

In fact, your RV can be parked in the shade on a hot day, and your portable RV solar panels can be placed in the sun. With panels that are installed, you either have to park your rig in the sun or you’re not harnessing its greatest power.

Portable solar panels for RVs allow the rig to be parked in the shade.

With portable solar panels, you can park your rig in the shade on a hot day, while leaving your solar panels out in the bright sun.

May Have USB Ports to Charge Devices Directly

Some portable solar panels for RVs have built-in USB ports that allow you to charge devices directly from the panel itself. This can be very handy for charging a phone or tablet while the panel is also charging your RV’s battery bank.

Some solar panels have USB ports for direct charging of small devices like cell phones and tablets.

Can Easily Connect to a Solar Generator for a Compact Power Station

A common use of portable solar panels is to connect them directly to a compact solar generator (a portable device containing a battery for storing power and often a small inverter for powering a 120V AC outlet), forgoing the need to deal with batteries and a charge controller. Many folks who travel in vans that are self-built RVs buy a solar generator and some portable solar panels instead of installing an entire electrical system.

A solar generator can be useful for charging many devices and appliances. Depending on the capacity of the solar generator, it can power laptop computers, small gaming devices, lights, a television, a CPAP machine, and/or a small 12V refrigerator.

There are larger solar generators that are capable of running more power-hungry appliances like hair dryers, microwave ovens, and other larger appliances.

What Are the Disadvantages of Portable Solar Panels for RVs?

While portable solar panels have many advantages, there are a few disadvantages to consider when deciding whether to invest in portable solar panels for your RV.


In general, portable solar panels are more expensive than solar panels that are intended to be installed (although that may be more than made up for by the lack of installation expense).

This is an expense some folks are willing to accept in exchange for a system that they can buy and use instantly without needing to consider the issues related to a more complicated installation.

Can Be Heavy

With portable solar panels, you have to remember that you’ll be moving them into and out of your rig over and over again, and moving them from place to place to take advantage of the sun.

Some portable solar panels can be quite heavy, so that should be taken into consideration as you’re shopping for the right portable system for you.

There are very small solar panels that don’t weigh much at all – in fact, we’ll feature a nice little 100 Watt folding solar panel at the end of this post that only weighs four pounds, and another that weighs in at only nine pounds. But you may be limited to 100 Watts or so with these very lightweight panels, so you’ll need to keep this balance in mind as well.

Require Setup/Breakdown At Each Site

When we roll into a new campsite, the most we need to do where our solar panels are concerned is to hit a button to tilt our rigid panels toward the sun. When we leave to move to a new campsite, the only thing we might need to do is hit that same button to return the rigid panels to their flat position.

When you’re using portable solar panels for your RV, every time you move you have to break down and store your solar array. When you arrive at a new site, you have to set them up again. This may not be a big deal at all for some folks, while for others it may be burdensome and/or a deal-breaker.

Rigid portable solar panels can be heavy and need to be set up and then collapsed and stored over and over again.

Need to Store Them When Not In Use

When your panels aren’t in use (for example when you’re traveling), you need to have room to store them. Depending on the type of portable panels you buy, this could require a fair amount of space.

A small folding solar panel isn’t a big deal to store away for travel. But larger rigid panels have to travel somewhere, and depending on the size of your rig, they could take up your entire basement storage… or even the hallway in the RV itself.

So, when shopping for a portable solar system, be sure to consider how you’ll store the panels for travel.

Possibility of Theft

Portable solar panels can be stolen, particularly when you’re not around. Many people break down their portable solar system and put the panels away if they leave camp to hike or explore (exacerbating the issue of setup/breakdown for use). This means that your RV’s house battery bank isn’t charging while you’re away.

If you leave your solar panels out, you need to be cognizant of the fact that they could be stolen.

This could depend on where you’re camping, of course. But, portable solar panels are a desirable commodity and are also expensive to replace.

Now that we’ve sorted through the pros and cons of portable solar panels for RVs, let’s take a look at some common questions about RV solar systems.

What Size Portable Solar Panel Do I Need to Charge My RV Battery?

This is a difficult question to answer definitively because there are a number of variables to be considered where solar is concerned. First, there’s the size of your battery bank and how much power you use, and then there’s the unpredictable variable of the sun itself. But we can address this question in generalities.

You might think that a 100 Watt solar panel will generate 100 Watts of power, but that’s not so because there are a variety of factors that will impact the amount of solar power your panels will actually produce. These include cloud cover, time of day, location, and ambient temperature. Even pollution and ozone play a role.

However, there’s a rule of thumb that experts use which says that in general, a 100 Watt solar panel will generate around 30 amp-hours per day. This means that on average, your 100 Watt solar panel will put around 30 amp-hours per day back into your battery bank.

Next, you’ll need to calculate your power usage. Then, remember that your goal is to have your power input come as close as possible to matching about 2x your daily power output/consumption (which helps to make up for less power provided on a cloudy/rainy day when the sun comes back out).

If you find that you generally consume around 30 amp-hours per day, remembering the general rule of thumb, a 100 Watt panel will give you around 30 amp-hours per day, so you’ll want either a 200 Watt solar panel or a pair of 100 Watt solar panels.

RV with large portable solar panel

Different wattages of solar panels will charge your battery bank at different rates. That’s why a 200 Watt panel will allow you to run more power-intensive appliances than a 100 Watt panel will allow.

What Can I Run With a 100 Watt Portable Solar Panel?

First of all, we don’t generally run a device or appliance with a solar panel (unless the portable panel has USB inputs to run small devices). The solar panel inputs energy/power into your battery bank (not directly but through a charge controller), and this is how the battery bank is charged to run your devices and appliances.

So, what this question really asks is how fast (and also how efficiently) a 100 Watt solar panel can recharge your battery bank as you use power from it.

With that in mind, we can offer some generalizations, but the real answer will depend on a number of variables including the nature of your electrical system/battery bank, the devices you’re running, how long you run them, how much sun the panels get, as well as several other variables.

Generally speaking, if you have a 100 Watt portable solar panel, your battery bank will likely be charged sufficiently to power small, low-power-draw devices such as your cell phones, RV lights, vent fan/Fantastic fan, tablets, small battery packs, and even your water pump – for variable amounts of time.

What Will a 200 Watt Solar Panel Run?

A 200 Watt solar panel will charge your battery bank sufficiently to run all of the above noted for the 100 Watt panel (for longer), and you’d also be able to run small appliances such as a coffee maker and a hairdryer if you have an inverter (though not for extended periods of time).

How Do I Connect My Portable Solar Panel to my RV?

This isn’t complicated, but there is a piece of information that’s critical to the process of connecting a portable solar panel to your RV.

A solar panel shouldn’t be connected directly to a battery. A solar panel would apply too much voltage and/or current to the battery which could eventually overcharge and damage the battery.

Between the solar panel and the battery, you need a solar charge controller. The purpose of a solar charge controller is to regulate the voltage and current coming from the solar panel/panels going to the battery/batteries, providing the proper charge cycle, voltage, and current to properly (and safely) charge your battery (based on it’s chemistry).

So, to connect your portable solar panel to your RV, you’ll need to connect the solar panel to the solar charge controller and connect the solar charge controller to the battery.

Now your portable solar panel will be charging your battery/batteries.

What Are the Best Portable Solar Panels for RVs?

Are Portable Solar Panels Worth It?

Depending on what you want to power and how you use your RV, portable solar panels may well be worth the investment for you.

For our RV lifestyle, installing a full solar array and electrical system was the only way to go.

But if you’re an occasional RVer, or you don’t have room on your roof to install solar panels, or you enjoy parking your rig in the shade and placing your solar panels in the sun – or if you simply want to dip your feet in the solar waters with a ready-to-go kit – portable solar panels may be just the right fit for you.

I have a 200 watt panel on the roof with its own solar controller and i have started to us a 190 watt suitcase with its own controller connecting through the port on the side of the camper. i know the controllers should work ok together but worried that the first battery in the parallel connection is going to get overrun with the two panels.


Sunday 16th of July 2023

It SHOULD be OK, Charles. But if you want to ensure that the charging is flowing more across the two batteries, you should check the connections for the solar charge controller: see if they are configured with the positive (+) wire going to the positive (+) terminal of one battery... and the negative (-) wire going to the negative (-) terminal of the other battery. That helps the charge to flow across both batteries a bit better.

I was under the impression you needed lithium ion batteries to work with solar. Am I just naive?


Thursday 23rd of December 2021

Hi Randy! Lithium batteries are absolutely not required for solar (solar panels have been around for a lot longer than lithium). But lithium makes solar that much better because they accept a charge so easily, among many other great benefits.

Our '17 Leprechaun 317 has a solar charger built in, with a coax connection. What panels are recommended that DON'T include a solar controller. Entire solar system will be upgraded as we go full time. For financial reasons, we want to gradually build it to include a converter/inverter.


Tuesday 21st of December 2021

Hi Bob & Dawn. We did some Googling and it looks like your Leprechaun likely has a Furrion solar connection port (read more here: You can either buy Furrion panels that will come with the correct plug for that port, or you can use any other panels that don't have a controller built in (see our comment below to Burt McCormick with some options) and then get an adapter to convert the panels' connector to the Furrion port.

Great article and, for me, great timing! I’m in the process of upgrading to Battle Born batteries and Victron components, intending to add solar in the future, including a stand alone solar charge controller.

Are there portable solar panels WITHOUT a built in charge controller that I could use with the set up I described, or could I use panels designed for roof top installation modified to sit on the ground? Might this be preferable for cost and expansion considerations?

Thanks for your attention, and your consistently excellent content!


Tuesday 21st of December 2021

Hi Burt... glad the timing on this article was good for you! There are, indeed, portable panels that come without a built-in (or included) charge controller. Renogy has them in 100W and 200W versions (here's the 100W on Amazon: Just be careful as the connectors may not match.

You could definitely fashion your own "ground deploy" panels using standard roof-mount panels... you'd just need to add some kind of stand mechanism. The big advantage to the portable kits is that they fold up to be more compact and come with their own charge controller to make them relatively "plug-and-play". But for a short-term solution, using a panel you plan to install on the roof as a portable system could work, too.

Hey guys. I hope you're having a wonderful holiday. I love the idea of portable solar panels. You can put one of them on one side of the RV, while the other can go on the other side. You can place one in front of the motorhome, and the other behind it. They can get stolen, so you want to make sure you're checking them.


Tuesday 21st of December 2021

Thanks for the additional tips, Jason! Happy holidays to you and yours, too.
