2 Types Of Portable Solar Panels For Rv Batteries – Flexible vs. Folding Solar Panels
There are 2 types of portable solar panels for rv batteries that make sense as charging options.
We compare flexible/bendable & folding solar panels for charging rv batteries
The first being flexible/bendable solar panels, and the second being folding solar panels.
Flexible solar panels are lightweight frameless thin laminate, and are sometimes bendable (up to around 30 degrees) to fit to curved and uneven surfaces.
Large folding solar panels (not to be mixed up with small folding solar panels) on the other hand are heavier, and consist of solar panels that fold out with a steel stand.
We already outlined these portable solar panel types in 3 types of solar panels for rv batteries.
But, below we will do a direct comparison of the portable types to help you decide which is best for you.
Specifically, rv batteries are usually 12 volt re-chargeable batteries.
So, when choosing solar panels for these batteries, the panels need to have enough output (watts and voltage) to re-charge the battery to capacity on any given day.
We wrote an informational guide on what size solar panels and how many you might need to do this.
Let’s look at the portable solar panel options you have…
Flexible Solar Panels
Read more about these solar panels in our short guide on flexible solar panels for rv’s.
What’s Good About Flexible Solar Panels?
Very lightweight
Frameless
Can bend usually up to a 30 degree arc – good for uneven or curved surfaces
Can be permanently, or temporarily installed – you could even use zip ties for temporary installation that wont leave marks or holes
Can be hung up on a tent
Good for a numbers of environments and applications – rv’s, cabins, cars, vans, boats, yachts, and anywhere essentially that will fit the panel/s
100 Watt models are available
Come with a number of resistant ratings for water, snow, hail, heat and more
What Are The Drawbacks?
Because they are made of thin laminate, they are more vulnerable to rough and sharp objects than say a rigid or folding solar panel
They vary in quality and price
Bubbling of the plastic can sometimes be an issue on lower quality panels
Folding Solar Panels
Read more about these solar panels in our short guide on folding solar panels for rv’s.
Note that for an Rv battery, a large folding panel is a realistic option, whilst small folding solar panels are more for small handheld devices like smartphones, tablets, radio, lights etc.
What’s Good About Large Folding Solar Panels?
Extremely easy to set up next to an Rv, and pack away and store in your Rv
Self supporting – no installation necessary. Only connections necessary to solar controller and battery
Good for a number of batteries – car, ATV, boat battery, Rv + more
120 Watt models are available
Weather resistance
Not as vulnerable to sharp and rough objects as a flexible solar panel
Will fold, unlike a flexible solar panel which can only bend/curve
What Are The Drawbacks?
Not cheap
Not as light as a flexible solar panel
Portable, but can only be folded out on the ground, and not hung up like a flexible solar panel
Can fold, but not bend. Bending may be better in some instances for solar panel use
Solar Panel vs Generator For An Rv: Which To Use?
Knowing the pros and cons of buying a solar panel vs a generator for an Rv is important.
Below we’ve outlined a short, but to-the-point list of the pros and cons of each power system, plus a brief summary of what each is and who they are suited to.
Let’s get to it …
Solar Panels
What’s Good About Solar Panels?
Clean sustainable energy which is good for the environment
Free to run once you install or set up
Doesn’t smell like a generator might
Completely quiet in operation compared to a generator
Can buy extras like solar generators which allow you to store DC to use whenever you like
Can be used with an inverter for AC power
Can complement a generator as a supplementary system
Can get portable solar panels which don’t require installation at all i.e. they can be used and positioned however you like, then connected to your system
What’s Not So Good?
Not as much power as a generator
Can’t handle high energy consumption – heating/cooling and high energy appliances like a microwave, oven, toaster, stove, hair dryer, air-conditioner and washing machine.
Drip charges over the course of a day – slow charging
Needs sunlight to charge (cloudy days and nights are an issue) – dependant on the weather and amount of sunlight available
Up front installation cost or purchase cost
Generators
What’s Good About Generators?
More power than a solar system – can handle high energy consumption such as heating/cooling
More reliable that solar – not dependant on weather
Quick and instant charging – you don’t have to run your generator for long to get your charge
Come as a traditional generator, or an inverter generator for AC appliances as well
Can be used with a solar system
What’s Not So Good?
Upfront cost to purchase – can be expensive
Continuous running cost to purchase fuel/gas
Leaves carbon pollution in the environment
Can smell like fuel – gas fumes are not pleasant
Can be noisy to operate – annoying for you and those around you
Some public camping spots don’t allow generators for noise reasons
So, Which Is Better For You – Solar Panel, or Generator?
The average Rv would probably have a combination of 12 volt lighting which might be LED, a pump for water, a small TV or radio, and a small DC operated fridge.
If you have this sort of set up, solar by itself should be fine for you if:
You have 1 or 2 12 volt DC Rv batteries
You have a well informed solar panel setup (you do your research, and get a manufacturer’s as well as an installation professional’s advice) – this article might help with estimating your solar panel requirements
You use your devices moderately
If you have any AC appliances, you could consider getting a solar panel sine wave inverter. And, even if you find yourself concerned about running out of power, you could consider a solar regenerator – which would allow you to store backup energy.
However, you would almost certainly get a generator if:
You are heavy on you energy consumption, or use heating/cooling and high energy appliances alot like a microwave, oven, toaster, stove, hair dryer, air-conditioner and washing machine.
You spend most of your time in areas with little sunlight
You absolutely need reliable and fast power
Can You Use A Solar Panel Setup, and A Generator Together?
Yes, you can.
In fact, a lot of people with generators are starting to use solar panels to supplement their generator usage – or just using solar panels themselves.
Solar panels top up your batteries during the day while you’re parked or driving, and sometimes you might not need to use your generator at all.
If for some reason your batteries don’t fully charge during the day due to a lack of sunlight, or you have to use your high energy devices – you can get out the generator.

How To Choose The Best Rv Solar Panels: 4 Time & Money Saving Tips
Having some knowledge of how to choose the best rv solar panels will save you time researching, and hopefully money in the long term by picking the panels that are right for you.
Different people are going to have different opinions and preferences for how to choose, but we’ve outlined some objective criteria for you to consider.
Let’s have a look …
When choosing the best solar panels for your Rv, you might like to consider the following:
1. Firstly, familiarise yourself with the types of suitable Rv solar panels available
There are three main types of solar panels you can choose from for your Rv.
These types are:
- Roof mounted solar panels (usually they stay on your roof, and are permanent)
- Flexible & Bendable solar panels (portable)
- Folding Solar Panels (portable)
You can read more about each in the linked guides.
2. Secondly, consider what you will be using the solar panels for
Which one of these two purposes will you be using the solar panels for:
1. Will you mainly be charging one or several Rv batteries, OR
2. Will you be charging smaller battery and USB devices like smartphones, tablets, radios, lights, GPS systems etc?
Roof mounted, flexible/bendable and large folding solar panels will be best for charging 12v batteries and other more power intensive uses.
The small 6-30 Watt folding solar panels you can carry with you are better for the smaller handheld devices – especially if you like to go hiking, riding, walking & camping.
3. Thirdly, estimate your power requirements
We are mainly talking about:
1. How many Watts from your solar panels you will need
2. How many solar panels you will need
You can read a guide we wrote on determining size and number of solar panels for Rv’s here, which has some useful informational guidelines.
For Rv batteries, a 100-120 Watt roof mounted, flexible/bendable or folding solar panel SHOULD produce around 17-19 volts when operating.
Providing you have enough sunlight hours in the day, one to two of these (with a properly rated solar controller to control the output from the solar panel) should be enough to charge one standard 12v Rv battery in a day – but, always check your battery and with the solar company.
20-30 Watt small folding solar panels are good for charging one to two small handheld type devices at a time.
4. Fourth, consider any other purposes you might use solar panels for
The flexible and large folding solar panels are easy to transport and use for other applications.
Home, boats, yachts, for cars and bikes, and more!
If you might like to use the solar panels for other purposes, other than just Rv related activities, make sure you confirm what the solar panel has been designed for.
For example, it’s possible you might be able to use a large folding solar panel at home with a compatible grid tie inverter connected to the solar panel junction box, to feed solar back into your house electricity supply.
You would definitely have to check for approvals, compatibility and other related factors though – but, it’s an added possibility.
And that’s it really (well at least the major decisions).
But, make sure you read up particularly on what the different types of solar panels can offer you, so that you get something which is suitable for your Rv setup, and gives you overall value for money.
Steps For Putting Together The Solar Setup For Your Rv
It’s most common for 12 volt DC Rv batteries to be charged with alternators or generators (with AC appliances being charged off mains, or DC inverters).
However, more Rv owners are using Rv solar setups when it comes to charging their Rv batteries.
If you are interested in this type of power setup, you have probably wondered what the best solar setup is for you situation.
You should know there are 3 types of solar setups you would look at for your Rv, with those being:
- Rigid Solar Panels
- Folding Solar Panels
- Flexible Solar Panels
Each has their own characteristics that make them unique, and you can read more about each in their specific guide’s below.
But, as an overall setup, you’ll want to determine things like the type of solar panel, the number, how you mount it etc.
That’s what the information below is for – we discuss solar setups – specifically, the types of panels, number of panels, fixing/mounting options, battery charging & more
Select The Type Of Panel
As we mentioned above, your solar panel type choices will probably come down to either rigid, folding or flexible panels.
1. Rigid Panels – are probably the best value for money of the 3 options. You can get a very basic 100 watt (1 panel) or 200 watt (2 panels) set up to charge 1 or 2 batteries for a very reasonable price. Rigid panels are usually fixed via brackets to the roof of your Rv.
Read more about rigid solar panels in this guide.
2. Flexible Panels – flexible solar panels are not perfect, but they are very versatile and a lot of people still find them very useful. They will either be lightweight laminate, or they will be laminate that bends up to around 30 degrees for uneven and curved surfaces. One of the big benefits of using flexible panels is that they can be permanently or temporarily fixed, stuck down, or even hung from tents. They usually won’t come in a starter kit like a rigid panel – you’ll have to buy a solar controller and cables separately.
Read more about flexible solar panels in this guide.
3. Folding Panels – A folding solar panel will usually come in a travel case, and fold out with a metal stand on the ground. A Go Power! folding solar panel comes with Anderson connectors to plug straight into a trailer pin attachment if you have one. Folding solar panels can simply be folded up and packed away when you aren’t using them.
Read more about folding solar panels in this guide.
*You’ll want to get a panel, connectors, solar controller, cables and fixings/brackets as a part of most setups.
Determine The Size and Number Of Panels You Require
This is a good guide to read for estimating the size in Watts and volts, and number of solar panels you might need.
When looking at size and number of panels, keep in mind:
Most panels come in 50 and 100 watt sizes (1 or 2 100 watt panels is a great start for most setups)
Most panels come in 18 volt ratings (a standard 12 volt battery needs 13.6 volts for a full charge)
If your batteries are banked together – make sure your total wattage and voltage coming from your panels is adequate.
A lot of people will go through and calculate the individual loads each appliance needs, but a better approach can be to look at wha the full charge of your batteries is.
Always look at how many daylight hours of sun are available to you
**Always look at product/manufacturer instructions, and get professional expertise if necessary for selection and installation
Determine How You Want To Fix The Panels, Or Use Them
Do you want to fix the panels to the roof of your Rv with mounting brackets? A rigid panel may be best for this.
Do you want the option to fix, stick on or temporarily fix the panels to different surfaces, including being able to hang the panels from a tent? A flexible panel may be best.
Do you want to pack the solar set up away, and fold it out on the ground as you need to? A large folding solar panel may be best for you.
Consider The Batteries You Want To Charge, and the Appliances You Have
Rv batteries usually come as starter batteries for the engine if you have one, and deep cycle batteries for appliances or lighting etc. that run consistently.
They might also come as lead acid, or lithium ion batteries.
Keep in mind that each of these types of batteries will require slightly different charging styles in terms of connections, stages of charging and more.
Appliances like LED lighting for example will use far less energy than a DC fridge.
If using AC appliances, you’ll need an inverter.
Consider Using A Generator or Alternator Charger As A Supplement
Using a generator, alternator, AC mains and solar to complement each other can be a very powerful setup.
But, you can also get away with using just 1 or 2 solar panels if you aren’t using your power all the time or very heavily.
A reminder of the benefits of solar…
Flexible and folding solar panels have a very wide application of uses
Initial set up price might even be less than buying a generator
Energy is essentially free once you’ve set it up
Can buy a solar regenerator to store DC energy, or an inverter to convert to AC energy
Best Folding Solar Panels For Rv
The best folding solar panels for rv use & rv related activities can vary in size.
Large folding solar panels are better for charging 12v rechargeable rv batteries (multiple panels are often needed for 24v batteries – check with the manufacturer).
The smaller folding solar panels won’t deliver as much output, but have the advantage of being more portable, and better for small USB and small battery devices you might use in or around your rv.
We’ve listed and analysed each of those types of folding solar panels below in this short guide, inc. reviews, & foldable solar panels for rv battery charging, and for smaller USB devices

Types Of Folding Solar Panels For Rv Use
There are really two types of folding solar panels that would be used for rv use:
The smaller 7-20 Watt highly portable folding solar panels
The larger 80 Watt & more folding solar panels
What Are Folding Solar Panels Used For With Rv’s
7-20 Watt folding solar panels
These panels are used for charging smaller devices that take a USB connection or small batteries (AA, AAA) to charge.
These are devices like smartphones, tablets, GPS systems, lights etc.
80 Watt + folding solar panels
For folding solar panels larger than say 80 Watts, these panels are designed to charge larger batteries and larger devices.
You might charge a 12 volt, or 24 volt (with multiple panels to meet the voltage requirements) rv battery.
You might even charge larger appliances like camper fridges.
What Folding Solar Panels To Use – How To Choose?
Ask yourself what you are looking to achieve with the folding solar panel if you want one:
Are you more looking for a panel you can take with you, and is designed for your smaller/handheld devices?
Or, are you looking for a panel that is easy to fold out and fold up, but is designed more for your larger 12 volt batteries and has a heap more output?
Features To Look For In Folding Solar Panels For Rv Use
You can read about features to look for in folding solar panels in this guide.
However, specifically look out for these considerations for folding solar panels for rv use:
If you want to charge an rv battery – 12 or 24 volt – make sure the panel voltage and amperage output is above what the battery requires. Check with the manufacturer, as you may have to buy two 120 watt panels to charge a 24 volt battery for example.
Check that the solar panel has the connections you need for the devices you want to charge i.e. USB, battery, anderson connections etc.
Check whether you need a solar controller to charge the devices you want to charge so you don’t damage them
Check exactly what the panel is designed for – how many devices can you charge at a time? How long will the panel take to charge the devices you want to charge?
Check whether it’s best to get a regenerator to store energy so you can use the stored energy when the sun isn’t out
Solar Panels For Rv Use – Accessories
You can read about features to look for in folding solar panels in this guide.
However, specifically for folding solar panels for rv use, you may need these accessories:
Solar controller – to prevent damage to your devices
Regenerator/charger – to store energy to use when you aren’t direct charging from the solar panel
Extra connections and adapters – like a trailer connector pin for example
Best Flexible Solar Panels For Rv
Flexible solar panels are one of a number of solar options for your rv roof.
One benefit they have over rigid or glass solar panels for example, is that they don’t need to be permanently fixed or mounted to your rv roof.
The best flexible solar panels for rv use can be very easily installed and uninstalled from different types of surfaces.

Best Flexible Solar Panels For Rv: Buyer’s Guide & FAQ
What Types Of Flexible Solar Panels Are There For Rv’s?
There are two types of flexible solar panels and both are good for Rv related tasks:
Flexible and semi flexible solar panels – flexible solar panels made of laminate that are lightweight, but can’t be bent
Bendable flexible solar panels – flexible solar panels made of laminate that are lightweight, but can be bent usually up to around 30 degrees (bent does not mean folded)
What For, & How Are Flexible Solar Panels Best Used With Rv’s?
What Are They Used For
Flexible solar panels usually come in 50 & 100 watt models.
Most people will want to use them for charging a re-chargeable lithium ion or lead acid battery in their rv, or other 12 volt batteries (although some batteries are 24 volt).
Multiple solar panels may need to be purchased to meet the voltage requirements of your battery if it’s anything higher than 12 volt.
1 x 100 Watt flexible solar panel is usually enough for a 12 volt battery – but check with manufacturer instructions.
How Are They Used
Flexible solar panels are used as a more versatile option to rigid, glass and aluminium/hard solar panels.
Rigid solar panels usually have to be permanently fixed or mounted to an rv roof with brackets and fixings.
Flexible solar panels on the other hand can essentially be quickly transferred between any surface.
They can be used on a an rv rooftop, boat, yacht, cabin, hung from a tent, and other irregular or curved surfaces where a hard solar panel might not be suitable.
Applications like the home, travel, camping, hiking and fishing are good for flexible and semi flexible solar panels – in addition to rv’s.
What Flexible Solar Panel To Get For An Rv – How To Choose?
You usually need 1, or 2 x 100 Watt flexible solar panels with a solar controller (so you don’t damage your battery long term) to charge an rv 12v battery.
Generally (but check the solar panel product info, and the requirements of your battery/s), 1 x 100 watt flexible solar panel puts out around 18.6 volts.
For a 12v re-chargeable battery, this will be sufficient.
What Features To Look For & Considerations To Make In Flexible Solar Panels For Rv’s?
You can read about features to look for in flexible solar panels in this guide.
However, specifically look out for these considerations for flexible solar panels for rv use:
If you want to charge an rv battery – 12 or 24 volt – make sure the panel voltage and amperage output is above what the battery requires. Check with the manufacturer, as you may have to buy two 120 watt panels to charge a 24 volt battery for example.
Check that the solar panel has the connections you need for the devices you want to charge i.e. battery, Mc4 connections etc.
Check whether you need a solar controller to charge the devices you want to charge so you don’t damage them
Check exactly what the panel is designed for – how many devices can you charge at a time? How long will the panel take to charge the devices you want to charge?
Check whether it’s best to get a regenerator to store energy so you can use the stored energy when the sun isn’t out
Flexible Solar Panels For Rv’s – Accessories
You can read about features to look for in flexible solar panels in this guide.
However, specifically for flexible solar panels for rv use, you may need these accessories:
Solar controller – to prevent damage to your devices
Regenerator/charger – to store energy to use when you aren’t direct charging from the solar panel
Extra connections and adapters – like MC4 for example
Best Portable Solar Panels For A Rv
The best portable solar panels for Rv use are flexible/bendable, and folding solar panels.
Flexible solar panels are usually made of an extremely lightweight laminate, and are easy to install/uninstall between a number of locations and surfaces.
Folding solar panels won’t give you the same power output for the same price as a flexible solar panel, but the upside is they are made of tougher materials, and some can even be carried out on, or in your backpack.

Best Portable Solar Panels For Rv: Buyer’s Guide & FAQ
What Are Portable Solar Panels For Rv’s?
Portable solar panels when used with Rv’s are panels that don’t need to be permanently fixed to the Rv roof.
What Types of Portable Solar Panels Are There For Rv Use?
There are two types of portable solar panels for Rv use – folding solar panels, and flexible solar panels.
Flexible, semi-flexible & bendable solar panels
Can be transferred between the Rv roof, and other locations like boats, home roofs, cabin roofs, or even hung up on a tent. Lightweight, frameless, and made of thin laminate that is vulnerable to rough or sharp materials.
They are sometimes bendable and so are suitable for fitting to curved surfaces.
Folding solar panels
Can be folded out on the ground, or carried around with you on a backpack, or in one. Lightweight and hard wearing/durable.
What Are Portable Solar Panels Used For With Rv’s?
Flexible, semi-flexible & bendable solar panels
Flexible solar panels tend to be rated at a higher Wattage than most folding solar panels – around the 80-120 watt and above mark.
They are mostly used for charging 12 volt lead acid or lithium ion batteries on an Rv (can also be commonly used to charge marine and bike batteries). They are best used with a solar controller to control the output from the panel/s into the battery to prevent short term or long term overload damage.
Folding solar panels
There are larger high wattage folding solar panels, but these are less common.
Most folding solar panels are smaller in the range of 6-20 Watts, and are used to charge small USB & AA/AAA battery devices like smartphones, tablets, GPS systems, radios etc.
Which Portable Solar Panels To Get For Rv’s – How To Choose?
Consider the following …
Flexible, semi-flexible & bendable solar panels
Thin laminate, lightweight, frameless, pre formed mounting holes for temporary or permanent fixing. More vulnerable to rough or sharp objects. Better for charging larger devices and batteries.
Folding solar panels
Large folding solar panels can be folded out at your rv site and are ready to use once connected – no installation necessary. Better for charging Rv battery.
Smaller folding solar panels can be carried with you and have attachments loops or mounts for attaching to backpacks, bikes, kayaks etc. Better for smaller handheld devices.

Best Rigid Solar Panels For Rv Roof: Buyer’s Guide & FAQ
What Is A Rigid Solar Panel For An Rv Roof?
A rigid solar panel is a solar panel setup that is usually permanently mounted or fixed to an rv roof.
They usually consist of a mono-crystalline or polycrystalline solar panel, glass, and an aluminium frame.
NOTE: most people use their framed solar panels mounted to their roof, but SOME people do use them as freestanding units too.
What Types Of Rigid Solar Panels Are There For Rv Roofs?
Rigid solar panels are mostly similar to each other – apart from their maximum output (watts and volts), and accessories you might get with them.
50 and 100 watt panels seem to be the most common sized of the rigid solar panel options.
They differ to portable solar panels mainly in the fact that they are permanently fixed, have a steel/aluminium frame, are heavier & sturdier, and are usually the most cost efficient purely on a price paid compared to power output basis.
What Are Rigid Solar Panels Used For With Rv Roofs?
Rigid solar panels are mounted with brackets and fixed to an Rv roof.
From there, they are connected to a solar controller, and used to charge a re-chargeable lead acid or lithium ion Rv battery.
Solar controllers are used because say a 100 Watt panel operates at 18.9 volts, and the 12 volt battery needs 13.6 volts to fully charge – a controller will limit the volts to what the battery needs so the battery isn’t damaged in the charging process.
Which Rigid Solar Panels To Get For Rv Roof – How To Choose?
It’s really just a matter of checking 3 main things:
1. Check your Rv manufacturer instructions to see whether installing of a solar panel has any impact on the Rv itself (and the battery), or on any existing warranty. If ok, are there any weight restrictions for example?
2. Check the solar panel instructions for installation – does the have the right materials and accessories (brackets and adapters) to install on your Rv?
3. Decide what size (Watts), and how many solar panels you want based on the charging requirements of your Rv battery, and how much space you have available on you Rv roof
Features To Look For In Rigid Solar Panels For Rv Roof
What is the wattage output of the panel?
What is the operating voltage output of the panel – is it enough to charge the battery you want to charge or will you need several panels?
Is the panel frame corrosion proof?
What weatherproofing and resistance does the panel setup have – wind, rain, snow, heat protection?
Check what the mounting and fixing practice is for the panel
Do you need an inverter to use with the panel for any batteries or devices you want to charge?
Check the solar controller the panel comes with – what are the capabilities and limitations of the controller?
Check the length and capabilities of any adapters and cables you get – are they long enough and will they be suitable for you charging needs?
Are you getting a standalone solar panel, or a whole kit with controller, adapters, cables, brackets etc?
Usually solar companies recommend at least 3 stage battery charging – check how many stages does the solar panels have that you buy?
How much do the solar panels weigh?
What size/dimensions are the solar panels – how many can you fit on your rv roof?
Are there separate warranties for the panels, materials, and accessories (controllers and cables/adapters)? If so, what are they?
How many purchasing options do you have for the solar panel kit? e.g. can you buy it with mono OR poly crystalline panels, different solar controllers, with and without a kit?
Rigid Solar Panels For Rv Roofs – Accessories
Apart from the solar panel, accessories usually include:
Z Brackets/Suitable Mounts (for fixing the panel to the rv roof)
Solar Controller (controls amps and volts between panel to battery)
Adapters (between the panel and solar controller)
Tray Cables (between the controller and the battery)
Additional accessories (optional) may include a solar storage battery, and/or an inverter
3 Types Of Solar Panels For Rv Battery Charging
There are a few options when it comes to solar panels for Rv battery charging.
Most Rvs will have a 12v battery (or maybe several), with the bigger motorhomes sometimes having 24v batteries, and sometime higher voltage.
In this article, we discuss options for the 12v battery rvs (check yours is solar re-chargeable).
Below we list & summarize the 3 types of solar panels suitable for rv battery charging
You can also read more about those options in the following buyer’s guides if you want to know more:
- Fixed/Mounted Solar Panels (fix to Rv roof)
- Flexible Solar Panels (portable, bendable, thin laminate film panels)
- Folding Solar Panels (portable, durable, compact panels)
3 Types Of Solar Panels For Rv Battery Charging
1) Fixed/Mounted Solar Panels
Fixed solar panels are rigid (they don’t bend), and they are usually mounted to the roof of the Rv permanently, or semi-permanently with some type of bracket.
They will be a mono-crystalline, or poly-crystalline solar panel in an aluminium frame.
As a guide, a 100 Watt mounted solar panel will usually have enough operating voltage (between 18-19 operating volts) to charge one 12v battery (which needs slightly more that 12 volts).
Most solar panel manufacturers will recommend using a solar controller (to protect the battery) with 3 or 4 stage charging.
Main Benefit – The upside to using a fixed solar panels is that they are generally a more cost efficient option (you get more output and value for money for the same price) than the other types of solar panels.
Read more about Fixed/Mounted Solar Panels here.
2) Flexible Solar Panels
Flexible solar panels can be just lightweight, or they can be lightweight and bendable i.e. they can curve up to a certain amount of degrees.
The bendable flexible solar panels are good for surfaces which are curved or uneven.
Flexible panels are made of a very thin laminate, and are frameless.
A 100 Watt flexible solar panel will usually have enough operating voltage (between 17-18 operating volts) to charge one 12v battery.
Most solar panel manufacturers will recommend using a solar controller with 3 or 4 stage charging.
These panels can usually be used on a range of surfaces including Rv’s, boats, yachts, vans, cars, cabins, home roofs & hung up on tents.
Main Benefit – can be installed temporarily and transferred to another surfaces quickly and easily. Very versatile and lightweight!
Read more about Flexible Solar Panels here.
3) Folding Solar Panels
Folding solar panels come in larger and smaller models.
- Large Folding Solar Panels
The larger folding models are usually 80-120 Watts, fold out on the ground, and have a steel stand which props them up.
These models are usually used in conjunction with a solar controller to charge one 12v battery.
These models are usually quite expensive for the output/performance compared to a mounted panel.
Main Benefit – as easy to to setup and pack away as folding out and connecting the controller and cables/connectors up to the battery (this is assuming you’ve already assembled the panel out of the box properly). Portable.
- Small Folding Solar Panels
Small folding solar panels ARE NOT used to charge 12v batteries as they usually don’t have enough output.
However, if you want to know more about them…
The smaller folding models are usually 6-30 Watts, and fold out to a compact size that can be carried around.
A 20 Watt model fro example can usually be used to charge small battery devices and USB devices like smartphones, tablets, radios, lights etc.
Small folding panels are so portable – they often have mounting points or attachments to attached to a backpack for backpacking, hiking, kayaking, biking and bike touring & more.
These panels are very durable and hard wearing, but lack the output of the above panels.
Main Benefit – can be carried around with you and charge small battery devices.
Read more about Folding Solar Panels here.
NOTES:
Always check your Rv manufacturer’s instructions for charging the battery/s, and solar panel manufacturer instructions for charging, before you consider a solar panel for your rv. This goes for other batteries like marine, ATV, and bike batteries too.
To charge devices that work on household or grid electricity, you will need a solar inverter.
What Is The Best Solar Panel For An Rv Trailer?
Rv’s trailers come in different shapes and sizes, with some even being custom made to suit your needs.
However, most standard rv trailers and travel trailer have a 12v or 24v battery system which powers various devices within the trailer such as LED lighting & other DC operated devices.
In the last few years, significant advances have been made which has allowed affordable solar power options to be made available for Rv travel related activities.
Below we’ve listed for you the best solar panel for Rv trailer options.

Solar Panels For Rv Trailers: Buyer’s Guide & FAQ
What Types Of Solar Panels Are There For Rv Trailers?
You have three main options when it comes to choosing solar panel/s for your rv trailer:
- Roof mounted solar panels
– mounts with brackets to the roof and generally stays there
- Flexible/Bendable thin film solar panels
– portable and transferrable between different surfaces
- Folding solar panels
– folds out on the ground – portable, with only setup and pack down required
These types of panels are all much smaller and more portable than the ones you see on a common house or dwelling roof.
What Are Solar Panel Used For On Rv Trailers?
Solar panels are used to charge the 12v or 24v battery setup you have in your Rv trailer.
Most solar panel manufacturers will recommend you use the panels with a solar controller – especially if the voltage of the panel is far higher than the voltage of the battery.
This helps you control output from the panel into the battery when charging – protecting the battery’s life.
Batteries in rv trailers and camper trailers are usually used to power things like LED lighting, a fridge, a small TV, small laptops and other devices like radios and GPS systems – as long as they can run on DC output/input.
Some devices may need an inverter if they run on household AC power instead of battery DC power, whilst other devices like smartphones and tablets can also charge from USB connections if you have them (some solar regenerators have them – such as the ones from the Goal Zero range).
3 or 4 stage protection charging is also a feature of most panel and controller setups that most solar manufacturers suggest.
What Solar Panel To Get For An Rv Trailer – How To Choose?
When choosing the type of solar panel for an Rv trailer, you may consider the following things:
1. Whether you want a mounted solar panel, or one that can be hung up, or folded out
2. The watts and volt capacity of the panel/s (if you get more than one) – the panels need to meet the charging requirements of your rv trailer battery setup
Here is an informational guide on choosing solar panel size, and how many you might need.
3. Do you need solar power for any other applications such as at home, on a boat/yacht, at a cabin, car, van, etc? Look at what the solar panel you choose is designed for – it might be suitable for several applications in addition to use for your Rv trailer.
4. Look at the type of connections and accessories you need to charge your Rv trailer battery, and make sure the panel/s you get have them available and they are compatible
Features To Check, and Considerations To Make With Solar Panels For Rv Trailers
You can refer to these guides on the different solar panel types, for features and considerations to look for in each type of panel:
In particular with an Rv trailer, look out for the following capabilities:
You have the correct voltage and watts from the solar panel/s to the rv battery or batteries. Note – charging a battery bank of say a 24v battery system is different to charging individual 12v batteries
Make sure the solar panels have the capabilities to connect up to your battery setup e.g. Anderson connectors will be required for some batteries
NOTE: different solar panel setups (panels, connectors, cables, controllers, inverters) and different batteries (volts, A/h, deep cycle vs. starter batteries, lead acid vs. lithium ion batteries) will have different requirements for charging.
Always confirm compatibility and other requirements with the solar and battery manufacturers before you buy.
Solar Panels For Rv Trailers – Accessories & Extras
Common accessories with solar panels when using with an Rv trailer might include:
Solar controller
Cables
Connectors
An inverter or inverter box with different input types – DC, AC, USB
A solar regenerator or solar battery you can store DC energy to use when the sun isn’t out
Different attachments like pin trailer attachments
Best Solar Panels For Motorhomes
The best solar panels for motorhomes will be similar to other types of Rv’s.
Yes, you may need more panels for a large or long motorhome, but the panels for 12 v rechargeable batteries (which is what many motorhomes have) stays the same.
The options are between rigid, flexible and folding solar panels – each have their own set of capabilities, and benefits and drawbacks.
We put together short and easy to read guides for each of these types of panels for Rv’s in general. Read more in:

Fixed/Mounted Solar Panels Reviews
Motorhomes vs. Other Rv’s – How Are They Different When It Comes To Solar Panels?
The major differences comes in the following ways (there may be other smaller differences):
Whether the motorhome you have accepts solar panel installation (if you’re fixing mounted panels to the vehicle) – check with your motorhome manufacturer
Whether the motorhome accepts solar power, or inverted solar energy – usually most 12v or 24v re-chargeable lead acid and lithium ion batteries will
Larger motorhomes will usually use more power – so you may need a greater number of panels than a smaller Rv will
NOTES:
Without getting too in-depth about different motorhome types, motorhomes are a type of Rv that is an all-in-one vehicle/kitchen/bed.
This is in comparison to say a camper, camper van, rv trailer etc. that are either smaller, or have detached vehicles and cooking/sleeping facilities.
Motorhomes generally fit into 3 types or categories:
Type A Motorhomes – the massive motorhomes that look like a bus. They can be very heavily equipped with appliances, luxury features and supply space. The downsides are fuel economy and manoeuvrability e.g. its much harder to get around in this motorhome on a campsite than it would be with a smaller vehicle.
Type C Motorhomes – the second biggest of the motorhomes. They are defined usually by the cabin overhanging the vehicle.
Type B Motorhomes – the smallest and most compact of the motorhomes. Usually and all in one van type setup. Very manoeuvrable, but little cabin space.
What Types Of Solar Panels Are There For Motorhomes?
The same as for smaller or different types of Rvs. These are:
Mounted/Rigid Solar Panels
Flexible & Bendable Solar Panels
Foldable Solar Panels
What Solar Panels To Get For Motorhomes – How To Choose?
Before you choose a type of solar panel, you certainly want to check with the motorhome and solar panel manufacturers to check everything is approved and compatible.
After that, consider the following in making a decision on which to pick:
- Mounted/Rigid Solar Panels
– Generally you mount these to the roof permanently or semi-permanently with some form of bracket
– They tend to be a mono or poly crystalline panel with an aluminium frame
– They aren’t bendable or super lightweight like a flexible panel, and aren’t as easy to set up or carry around like a folding solar panel
– You tend to pay less for more output for mounted framed solar panels (more cost efficient), compared to flexible and folding solar panels
– 100 to 120 Watt panels (1 or 2 of them) are best suited for charging 12v re-chargeable batteries in conjunction with a solar controller, cable, adapters and sometimes an inverter and/or solar battery recharger
- Flexible & Bendable Solar Panels
– Made of a lightweight thin film laminate material – weather, water and heat resistant, but more vulnerable to sharp and rough objects
– Can bend a certain amount of degrees to fit uneven and curved surfaces
– Can temporarily be install, uninstalled and transferred between rv’s, boats, yachts, cabins, home roofs, hung up on tents and more. Very portable
– 100 to 120 Watt panels (1 or 2 of them) are best suited for charging 12v re-chargeable batteries in conjunction with a solar controller, cables and adapters and sometimes an inverter and/or solar battery recharger
- Foldable Solar Panels
– Come in both larger metal fold out, and compact carry-around versions
– Fold out means there is no installation required
– Larger fold out panels (80-120 watts) are best suited for charging 12v re-chargeable batteries in conjunction with a solar controller, extensions cables, pin attachments and sometimes an inverter and/or solar battery recharger
– Smaller folding panels (6-30 watts) are best suited for charging smaller USB and small battery devices: tablets, smartphones, GPS, radios etc.

Lightweight Solar Panels For Caravans: 3 Affordable Options
Some call it a caravan, whilst other call it an RV, camper van, motorhome or travel trailer.
Whatever you call it, you would have looked into different methods of on road and off road power for your van.
Whilst many might plug into an AC power source at a campsite, or have a DC generator to power appliances and charge batteries, there is another option which is to use lightweight solar panels for caravans.
A major benefit to using solar panels is that the energy is free and takes no effort once the panels are installed. On the other hand, a drawback is that solar panels lack the top end charging power or speed of a generator or mains – they are more a drip feed type system over a day.
In terms of portable type solar panel set ups, we are talking:
- Hard/Rigid Solar Panels
- Flexible Solar Panels
- Folding Solar Panels
Let’s get into an outline, and the a few positives/negatives of each type…
NOTE: most commonly, lightweight portable solar panels will be used to charge your 12 volt DC batteries, or DC battery devices via a regenerator with outputs/inputs. Some panels may also allow you to buy an inverter to charge your AC household appliances.
1. Hard/Rigid Solar Panels
Rigid solar panels are probably the best value for money lightweight and portable solar panels in terms of cost vs. power on this list.
They often come as complete kits for the price you might pay for one flexible or folding solar panel of a similar size.
Rigid panels are aluminium or steel framed, and aren’t flexible or bendable – they are flat, and stiff.
A basic hard solar panel starter kit will get you:
A 50 or 100 Watt 18 volt panel (generally, one panel is enough for one 12 volt DC battery)
Connectors
A solar controller (for connection between your panel and battery)
Cables
Brackets (for mounting the panel to your roof)
Because you are using brackets to fix the panel, once a panel is installed, it usually is permanent.
It’s also worth noting that a rigid solar panel can be pole or rack mounted, but it depends on the surface you mount them on.
2. Flexible Solar Panels
Some flexible solar panel users love them for their versatility, whilst other have experienced problems with them.
Flexible solar panels are made of solar layers or solar crystals laminated between plastic sheets, and come in 50 or 100 Watt models.
Some of these flexible panels are just lightweight, whilst others can bend up to a stated 30 degrees.
The frameless design and bend makes them good for uneven and curved surfaces.
They have been used for caravans/RV’s, boats, cars, vans, cabins, homes and even hung up on tents when camping.
They can be permanently or temporarily fixed through pre fabricated metal fixing holes, and some people even use an adhesive like silicon to stick them on to a surface.
Flexible panels usually come as a standalone panel with connectors, and you buy a solar controller separately along with cables.
It’s important to note that because flexible solar panels are made of laminate, they are more vulnerable to sharp and rough objects than a rigid solar panel.
3. Folding Solar Panels
Folding panels can be large folding solar panels, or the smaller folding panels you carry around with you.
To read about both – you can read more in this guide.
For the purposes of this article, we will discuss the large 120 Watt folding solar panels such as the Go Power! GP-PSK-120 120W Portable Folding Solar Kit.
A folding solar panel like this has the advantage of not being mounted to your caravan at all.
It comes with a handy travel case that you pack the folding solar panel away in, and unpack it when you need to use it.
The panel itself has a fold out metal stand, and sits on the ground while your caravan is stationary to charge to batteries.
Three things to note with this type of folding solar panel is:
- They might come with Anderson connectors instead of MC4 connectors
- You can buy a separate accessory like a trailer plug for direct charging
- You’ll probably want to get an extension cable so you can move your panel around further away from your caravan if that’s where the sun is
… How Do You Know Which Lightweight Solar Panels To Get For Your Caravan?
It’s really a matter of checking 3 main things:
1. Check your caravan manufacturer instructions to see whether installing of a solar panel has any impact on the caravan itself (and the battery), or on any existing warranty. If ok, are there any weight restrictions for example?
2. Check the solar panel instructions for installation – does the panel have the right materials and accessories (brackets and adapters) to install on your caravan?
3. Decide what size (Watts) you want your panel to be, and how many solar panels you want based on the charging requirements of your caravan battery/s, and how much space you have available on you caravan roof
Here is a helpful guide to help you determine what size solar panel (and how many you need) for a 12 volt battery.
*Always check manufacturer instructions though, and get advice from a professional if necessary though
3 Useful Tips For Choosing A Travel Trailer Solar Panel
Tips For Choosing A Travel Trailer Solar Panel – tips for owners of a travel trailer, or camping trailer, looking for solar power
A travel trailer solar panel can be a good stand alone, or complimentary charging system.
Depending on how much power you use in your travel trailer/camper trailer, there are some great benefits to going solar.
Solar is free and clean energy once you set it up, and even the set up cost can be cheaper than buying a generator outright.
Having said that, you do want to take into account the fact that a solar panel does require sunlight to be available in order for charging to occur.
From more spacious camper trailers to smaller trailers just for sleeping – let’s look at some great tips for travel trailer solar charging:
1. Consider the size of your travel trailer/camper trailer
Firstly, consider the size of your travel trailer – but mainly, how much power will it be using?
Do you have 2 fridges, lighting, a microwave, lights, a TV….and, basically a set up that will chew through power in 2 seconds?
If you fit into that category, you will probably need several 100 Watt or higher panels, and probably a generator + plus some type of inverter of AC form of power.
Or, do you on the other hand have just a few appliances like say a fridge, lights and a few smaller handheld devices?
If this is you, you might be able to use a small solar setup of say 2 x 100 watt panels, and perhaps a regenerator/DC storage battery to power your whole trailer.
But, rather than just look at the number of appliances and your usage, look at your battery requirements as well. Which brings us to the next tip…
2. Consider how many batteries you have to charge in your camper trailer, and their type
Solar panels usually connect up to your camper trailer via cables or connectors.
The most common method is using anderson connectors (which a solar panel like the Go Power! Folding Solar Panel has) – that connect straight in through a power output/input near the tow bar of your trailer.
Some trailer might allow you to slide some batteries out from the side of the trailer and charge them in other ways.
Regardless, assess how many batteries you have to charge, their voltage, and whether the batteries will be charged in the same system i.e. charged in a bank.
It’s very important that for each charging circuit, you have a solar panel setup (sending the power) that is rated for carrying the charge.
A standard 12 volt battery will need 13.6 volts to be fully charged – and a standard portable 100 watt 18 volt solar panel should be capable of charging 1 in a day with over 6 hours of direct sunlight – but this is only a guide, not a guarantee.
Of course there are deep cycle vs. starter batteries, batteries with different Ah, and different voltage batteries to consider as well.
As an estimation, you can read this guide for more information on how many solar panels are needed for a 12 volt battery.
Once you have a good idea of your battery requirements (number, total voltage and Ah as main indicators), you can then look at getting the number of panels and size of panel that suits your use.
*NOTE: always seek a professional opinion if required, and read manufacturer’s instructions for batteries, panels etc. when making a decision
3. Consider the size of the solar panels, and the type of panels you want to get
If you’re serious about an adequate quality solar system for your travel trailer, there are probably two types of portable solar panels to have a look at:
- Folding Solar Panels – the larger 120 Watt panels
- Rigid/Solid Solar Panels – 100 Watt and above solar panels
For any type of travel trailer, you wouldn’t want to look at anything less than a 100 Watt panel, unless you plan on having multiple 50 watt panels.
Rigid solar panels will need to be mounted to your trailer – usually the roof – with brackets, and are usually great value for money – being able to get a starter kit for an affordable price.
A large folding solar panel on the other hand will be able to be unfolded from a carry case, and folds out with a metal stand onto the ground.
The good thing about a folding solar panel is that there are models that come with Anderson connectors to plug straight into your tow bar input, and can be bought with cables and plug ins separately.
Both are good portable options.
If you are unsure of the size of panel – aim for around 80-120 Watts as a start, but contact a solar panel company rep if you’re unsure.
4. Consider the setup you have is good for a basic solar setup
Common parts to a basic/starter solar setup are:
A panel, or several panels
Connectors to plug into the junction box
A solar controller rated for the number of panels, and watts/voltage going through the circuit
Cables to connect from the controller to the batteries or batteries input/output
Obviously the batteries
Other extras and accessories are fixings, brackets, an assembly tool, LCD display monitor,
