Best Solar Panel for a Campervan – Complete Guide 2026
Looking for the best solar panel for campervan?
Choosing the right solar panel for your campervan can feel a bit like trying to buy the right hiking boots for a trip you have never done before. Everyone says it matters, everyone uses different terminology, and suddenly you are left wondering whether you really need the most expensive option or whether you are just about to buy something that will end up being too underpowered.
We remember what it was like ourselves the first time we tried to understand solar panels for a campervan. In theory, it sounded simple: the sun shines, the battery charges, life is good. But in practice, questions quickly started popping up about wattage, charge controllers, panel types, battery size, shading and mounting. Not least, how do you actually install solar panels on a campervan?
And that is exactly where many beginners get stuck. Because what you really want to know is not everything there is to know about solar power in the world. You want to know what actually works in a campervan, what is worth the money, and what you should choose so you do not end up regretting it later.
In this guide, we make it simple. You will get a quick answer straight away, clear product recommendations, help understanding the differences between the various options, and practical advice based on how you actually use your van.
The goal? To help you choose the right solar panel from the start and end up with a system that feels reliable, smart and genuinely useful in everyday van life.
Quick answer – Which solar panel is best?
For most campervans, a 200W monocrystalline solar panel with an MPPT charge controller is the best choice.
Our quick picks:
Best for most people: 200W SOLAR PANEL KIT WITH MPPT
Best for a lower budget: 100W MONOCRYSTALLINE SOLAR PANEL
Best for a low-profile setup: 200W FLEXIBLE SOLAR PANEL
Best as an add-on: PORTABLE SOLAR PANEL SUITCASE 100W
If you are a beginner and want to keep things simple: start with 200W + MPPT.
Vårt snabba val:
- Bäst för de flesta: 200W SOLPANEL KIT MED MPPT
- Bäst för låg budget: 100W MONOKRISTALLIN SOLPANEL
- Bäst för låg profil: 200W FLEXIBEL SOLPANEL
- Bäst som komplement: PORTABEL SOLPANEL SUITCASE 100W
Om du är nybörjare och vill göra det enkelt: Börja med 200W + MPPT.
Starting with a 200W solar panel and an MPPT charge controller is the point where the system begins to feel genuinely useful in day-to-day life. You will get enough charging capacity to run everyday essentials such as a fridge, lights and phone charging without having to rely so heavily on driving the vehicle or staying at campsites with hook-up power. For simpler needs, 100W can be enough. If you want to stay off-grid for longer periods or work from the van, 300–400W may be a better fit.
Why a solar panel is so worthwhile in a campervan
The great thing about a solar panel is that it does not just give you more electricity. It gives you more freedom, less stress and fewer compromises.
Without a solar panel, you become more dependent on driving the vehicle, staying on campsites with shore power, or constantly keeping half an eye on your battery level. If you have a fridge, fan, phones, lights and perhaps a laptop, you quickly notice how much more reassuring the whole system feels when the battery is being recharged during the day.
That is exactly why solar panels often become one of the most appreciated upgrades in a campervan. Not because they are the flashiest bit of kit, but because they make everyday life easier. They quietly do their job in the background while you get on with everything else.
And even if the upfront cost can feel like a hurdle, it is often an investment that makes your whole electrical system more usable and more self-sufficient over time.
How do you know what size solar panel you need?
This is the most important question to understand before you buy anything. Many people start at the wrong end and look at products first. But really, you should begin with how you use your van.
What you need to think about is how much electricity you use during a normal day in the van. Not on a perfect summer day in theory, but in real life.
Do you only have a few lights, charge your phone and occasionally run a water pump? Then your needs are fairly modest. But if you also have a compressor fridge, laptop, fan or diesel heater with electronic controls, your demand goes up quite quickly.
It is also important to understand that the solar panel does not replace the battery. The solar panel charges the battery, and the battery powers your appliances. So even a good solar panel works best when it is combined with the right battery bank.
A simple rule of thumb
Not sure? It is usually better to go slightly bigger than you first planned. A panel that is too small quickly becomes frustrating, whereas a slightly larger panel usually feels like a relief.
Suitable if you have a simple setup and mainly want to trickle charge or cover lighter usage during spring and summer.
200W solar panel
Suitable for most people building their first campervan and wanting to run a fridge, lights, charging and everyday essentials with more confidence.
300 – 400W solar panel
Suitable if you want to spend a lot of time off-grid, have higher power consumption, or work from the vehicle.
Start with the battery – not just the panel
A common misunderstanding is that you choose the solar panel first and sort out the rest afterwards. But if you really want to understand how the system works, you need to think about the bigger picture.
A solar panel is not a standalone solution. It is part of a system. The solar panels generate energy when the sun is out. The charge controller makes sure the charging happens properly. The battery stores that energy so you can use it when you need it.
That is why you should not buy a solar panel in isolation. If your battery is too small, you will not be able to store enough of the energy. If you have a large battery but too little solar capacity, you may struggle to charge it properly.
For example, if you have a small battery bank and fairly high consumption, simply adding more solar is not always enough. You also need enough battery capacity to receive and store that energy. In the same way, a large lithium battery does not help nearly as much if you hardly ever manage to charge it properly.
That is why we often say that solar panels and batteries should be seen as a team, not as two separate purchases.

What type of solar panel should you choose?
Once you start looking at products, you quickly come across different panel types. For most campervan builds, the choice in practice usually comes down to three main options:
- Rigid panels
- Flexible panels
- Portable panels
All of them can work, but they suit different types of builds and different styles of travel.
What is the difference between monocrystalline and polycrystalline?
You will often see panels described as either monocrystalline or polycrystalline. To a beginner, it can sound unnecessarily technical, but in practice it is fairly simple.
Monocrystalline panels are now the most common and, in most cases, the best choice for campervans. They are generally more efficient, which means you get more power from a smaller surface area. That is particularly important in a van, where roof space is almost always limited.
Polycrystalline panels can sometimes be cheaper, but they are usually larger for the same output and have become less attractive as monocrystalline panels have improved and become more affordable.
Our recommendation is simple:
Choose a monocrystalline panel if you are building a campervan today. It is the most practical option for most people.
Rigid or flexible solar panel?
This choice matters more in practice, because it affects performance, durability and how easy the system is to live with.
Rigid solar panel – Best for most people
A rigid solar panel is the classic design with an aluminium frame and a glass front. It is not the most discreet option visually, but it is often the best if you want strong performance and a long service life.
There are several reasons for that:
- They often last longer
- They are more resistant to weather and wear
- They are usually cheaper per watt
- They often get better ventilation underneath, which helps with cooling
That last point is easy to underestimate. Solar panels perform better when they stay cooler, which is why it is an advantage that they are not lying completely flat and sealed against the roof of your campervan.
For most beginners building their first campervan, a rigid panel is simply the safest purchase and also our general recommendation.
Flexible solar panel – Right for the right situations
Flexible panels appeal to many people because they are thin, lightweight and look more discreet on the roof. They can also be easier to mount on curved or uneven surfaces.
But they are not automatically better just because they look more streamlined. In fact, they can be:
- More expensive per watt
- More sensitive to heat
- Less durable over time
- More dependent on good installation to perform well
So our advice is this: choose a flexible panel when the shape of the roof or the visual design genuinely makes it the better option.
Portable panel – Best as an extra
Portable panels, or “solar suitcases”, can be a very smart option in certain situations. They are especially useful if you want to park in the shade but still place the panel out in the sun.
But they also need to be taken out, connected and packed away every time. They do not charge while you are driving or out doing errands, and they take up space inside the vehicle.
That is why we mainly see them as a complement, not the main solution for most campervans.
Our recommendations – Best solar panels for campervans 2026
Now we come to the part most people are really looking for: what we actually think you should buy. Here we have chosen three clear types of solutions. The idea is not to give you ten almost identical options, but to help you choose the right one based on how you actually plan to use your campervan.
Budget pick – A simple start for lighter needs
Suggestion: 100W MONOCRYSTALLINE SOLAR PANEL
This is a good choice if you want to get started sensibly without immediately building a large electrical system.
A 100W panel is not the wrong choice. It is simply limited. And if you understand that from the outset, it can be a very wise purchase.
It is best suited to those with a simple van, low energy use, and a need mainly to support the battery during the day. If you mostly use lights, charge phones, run a water pump and perhaps spend occasional time away during spring and summer, then 100W can go surprisingly far.
What it is rarely perfect for, however, is running a fridge plus several other loads for longer periods off-grid. That is where its limitations become obvious quite quickly.
Why we like it:
It is a simple, affordable and easy way to get started. You learn how the system works without investing too much too soon.
Suitable for you if you:
- Want to start simply
- Are building on a budget
- Have low electricity usage
- Mostly take shorter trips
Best value – Our top pick
Suggestion: 200W SOLAR PANEL KIT WITH MPPT
This is the solution we would recommend to the greatest number of readers on CamperPals.
Why? Because this is where the system starts to feel like a genuine upgrade in everyday life. Not just like a panel on the roof, but something that actually gives you more freedom.
With 200W, you get better headroom. You can put more charge back into the battery during the day, you stand a better chance of keeping the battery level stable, and you can use your campervan in a more relaxed way. If you have a fridge, lights, water pump and standard charging needs, this is often the right level.
Choosing a kit with an MPPT charge controller also makes life easier. You get components designed to work together, which reduces the risk of buying the wrong things or missing important parts. And MPPT makes a real difference, especially in Nordic, German and British weather where the sun is not always “Instagram perfect”.
Why we like it:
This is the sweet spot between price, performance and practicality. It is often the point where you stop thinking about battery level all the time.
Suitable for you if you:
- Are building your first proper campervan
- Want a fridge, lights and everyday electrical comfort
- Want to stay off-grid for several days
- Want a dependable all-round solution
Premium pick – When low profile or roof shape matters most
Suggestion: 200W FLEXIBLE SOLAR PANEL
This is the choice for anyone who values form factor more than outright performance per pound.
A flexible panel can be absolutely right if you have a curved roof, want a more discreet appearance, or for some reason do not want to install rigid framed panels. In some builds, it is simply the most practical solution.
But we think it is important to be honest: for most people, a flexible panel is not the most cost-effective option.
The main advantage is design and installation. The downside is often service life, heat management and a higher price per watt.
So if you choose a flexible panel, we think you should do so for the right reasons, not because you assume it is automatically “premium” in terms of performance.
Why we like it:
It solves specific build challenges that rigid panels do not always handle as neatly.
Suitable for you if you:
- Accept the trade-off in lifespan and price
- Are building a more discreet or stealthy van
- Have a curved or awkward roof
- Prioritise a low-profile look
Smart add-on – Park in the shade
Suggestion: PORTABLE SOLAR PANEL SUITCASE 100W
This is not our first choice as a main solution in a campervan, but it can be a very clever add-on.
A portable panel works well if you often want to park the van in the shade while still charging in the sun. It is also interesting if you do not want to drill into the roof, have limited roof space, or simply want a solution that is easy to bring out when needed.
At the same time, it is only fair to say that portable means more effort. You need to set it up, aim it, connect it and put it away again.
Why we like it:
It gives you flexibility and can be perfect for the right style of travel.
Suitable for you if you:
- Want to charge in the sun while parking in the shade
- Do not want to roof-mount straight away
- Want an extra panel as a supplement
Comparison – Which type suits you best?
| Type | Best for | Advantages | Disadvantages |
|---|---|---|---|
| 100W monocrystalline | Simple setup, lower budget | Affordable, easy start | Limited output |
| 200W kit with MPPT | Most beginners | Best balance, easy all-round solution | Slightly higher upfront cost |
| 200W flexible | Curved roofs, low-profile builds | Discreet, lightweight | More expensive, shorter lifespan |
| Portable 100W | Supplement, shaded parking | Flexible use | Requires manual handling |
MPPT or PWM – Which charge controller should you choose?
This is one of those details that many beginners are tempted to skip over, but it actually makes a big difference in real life.
The charge controller sits between the solar panel and the battery and controls how charging takes place. If you choose the wrong one here, you can lose unnecessary energy every single day.
PWM is the simpler and cheaper type. It can work in simpler systems, especially with lower demands and smaller panels. But it is less efficient.
An MPPT controller is almost always the better choice if you want to get more out of your panel. It charges more efficiently, especially when the weather is not ideal, temperatures vary, or light levels are less than perfect.
That is exactly why we recommend MPPT for almost all campervans in Sweden, Germany, the UK and northern Europe. You are not building for constant Mediterranean sunshine, you are building for real conditions.
Our recommendation:
Choose MPPT if you can. It costs more at the start, but usually delivers better value every day.
Fixed or portable mounting?
For most people, a fixed roof-mounted panel is best. It charges automatically, takes up no space inside the vehicle, and works whenever the sun is out – without you having to do anything.
A portable panel is smart if you want flexibility and the option to place the panel separately from the vehicle, but it is generally better as an add-on than as the main solution for most builds.
If you are building your first campervan and want a system that is easy to live with, choose fixed mounting first.

Common mistakes people make when buying a solar panel for a campervan
For many readers, this is probably the most important part of the article. Because it is rarely a disaster to buy an “okay” panel, but it is very common to buy a system that does not quite suit your needs.
1. Choosing too small a panel
This is perhaps the most common mistake. Many people think 100W will “probably be enough”, only to realise later that they still have to be overly careful with the fridge, charging and lighting. At that point, the solar panel becomes more of a psychological comfort blanket than a real solution.
2. Focusing only on the panel
The panel matters, but without the right charge controller, the right battery and a sensible overall setup, the result will still be underwhelming. A good solar setup is exactly that: a system.
3. Choosing a flexible panel for the wrong reasons
A flexible panel is great in the right build, but it is not automatically the best choice for every campervan conversion.
4. Forgetting about shading and placement
A small shadow from a roof vent, roof rack or storage box can affect a panel’s output much more than people think. Roof layout matters more than many beginners realise.
5. Underestimating the weather
Solar panels in a campervan absolutely work in Sweden, Germany, the UK and northern Europe, but they require realistic expectations. You are building for real-world use.
Advanced tips if you want to optimise later
Once you have the basics in place, there is a lot to gain from optimisation. For example, you can:
- Combine multiple panels
- Plan better airflow underneath rigid panels
- Choose smarter positioning to reduce shading
- Wire panels in series or parallel depending on the system
- Add battery monitoring for better oversight
But above all, this article is meant to help you choose the right level from the start. If you want to go deeper into installation, sizing and technical details, we recommend our more detailed guide.

Campervan Electrical System
Advanced tips if you want to optimise later
Once the basics are in place, there are a few things that can take the system to the next level.
One example is using several panels instead of one large one, especially if your roof layout is awkward. Another is thinking carefully about whether the panels should be wired in series or parallel depending on the charge controller and overall system design.
There is also a lot to gain from choosing the right mounting solution, leaving an air gap under the panels, and understanding how shadows from other equipment affect production.
But we think it is sensible not to make this article unnecessarily technical. The goal here is to help you choose the right setup from the beginning. If you want to dive deeper into how everything works in detail, we recommend moving on to our more complete guide to solar power in a campervan.

If we are going to make it really simple
Choose a 200W monocrystalline solar panel kit with an MPPT charge controller if you are building your first campervan.
It is the solution that suits the greatest number of people, gives the most practical benefit, and usually still feels like the right choice long after the initial excitement has worn off.
It is powerful enough to make a real difference, but not so large or complicated that the build starts to feel excessive.
If your electricity use is very simple, you can start with 100W. If you already know you want to stay off-grid for long periods or run more power-hungry equipment, it may be wise to go bigger straight away.
But for most beginners, 200W is the point where things feel right.
FAQ – Solar panel for a campervan
Is a 200W solar panel enough for a campervan?
Yes, for many campervans 200W is a very good level. It is often enough for a fridge, lights, water pump, phone charging and some laptop use, especially when paired with the right battery and an MPPT charge controller.
Is a flexible solar panel better than a rigid one?
Not for most people. Rigid panels are usually more durable, better value for money and better ventilated. Flexible panels are mainly useful when a lower profile or the shape of the roof makes them more practical.
Do I need MPPT, or is PWM enough?
PWM can work in simpler budget systems, but MPPT is almost always the better choice if you want more charging power and better efficiency.
Is a portable solar panel worth it?
Yes, as an add-on it can be very smart. As a main solution, however, it is often less convenient than a fixed roof-mounted panel.
Do solar panels work in Sweden, Germany and the UK?
Yes, absolutely. You will not get the same output as in southern Europe all year round, but a properly sized system is still highly useful in more northerly climates.
How can we install solar panels cheaply and on a small budget?
A 100W panel is not the wrong choice, it is simply limited. For most campervans, a 200W solar panel with an MPPT charge controller is the best option.
