What Is a Portable Solar Panel?
Portable solar panels are – as they sound – solar panels designed to be taken anywhere. They’re typically smaller, foldable solar panels often used for camping, home backup, motorhome trips, and outings. Portable solar panels come in a variety of types, with the two most popular being monocrystalline and polycrystalline.
How Do Portable Solar Panels Work?
Portable solar panels are often used with a portable power station to store energy for later use. They work just as standard solar panels do, converting sunlight into electricity.
Portable solar panels are made up of lots of photovoltaic cells – otherwise known as PV cells – that contain semiconductor materials, which as of 2022, are predominantly silicon-based. When sunlight strikes the cell, it creates an electric field across the layers of the semiconductor. This generates a current that can be harnessed and stored in a battery, such as an EcoFlow portable power station. That’s how solar panels work. When solar panels and batteries are paired, they’re often called Solar Generators, as they fulfil the same needs as traditional fossil fuel generators — without the environmental impact, fumes, and noise.
Types of Portable Solar Panels
When looking at the differences between portable solar panels, you’ll want to consider whether you need monocrystalline or polycrystalline panels. They have distinct differences that’ll influence your purchase decision.
Monocrystalline Portable Solar Panels
Monocrystalline panels are characterised by their sleek black appearance. Due to a more advanced manufacturing process, they’re more efficient than their polycrystalline cousins. That makes them a superior pick for portability with a slightly higher price tag to match.
Monocrystalline panels could be monofacial (meaning one panel on one face) or bifacial solar panels with panels on both sides to benefit from ambient light.
Polycrystalline Portable Solar Panels
Typically rigid, with a blue marbled appearance, polycrystalline solar panels have lower efficiency and are often used for rooftop panels due to their cheaper price tag. They can still be used as portable solar panels but have some trade-offs as they’re usually cumbersome compared to monocrystalline.

Rigid Solar Panels vs Foldable Solar Panels
Another sub-category of portable solar panels is rigid and foldable solar panels. Rigid panels are — as you might suppose – unbendable. They’re stiff boards typically mounted on a rooftop, motorhome, or van. They are sometimes used for camping too. Foldable solar panels, in contrast, can be quite compact due to their design. EcoFlow’s Solar Panels are foldable, allowing you to carry them with ease in a carry case.
Who Are Portable Solar Panels / Solar Generators For?
EcoFlow solar generators are used for anything you can use a traditional fossil fuel generator for as they have high outputs. The key advantages are that they don’t create fumes or noise, and you can charge with the sun using a portable solar panel. This makes them ideal for indoor environments — such as home power backup or motorhomes — and camping, where sound and fumes could disturb your trip.
Portable Solar Panels for Camping
If you take a solar generator camping, you can keep all your home comforts running. With more people taking electronics camping than ever before, portable solar panels are a natural fit. Use the sun to charge your battery, then power appliances such as laptops, speakers, mini-fridges, projectors, and more. Camping just got so much comfier.

Solar Panels for Home Backup
When a blackout hits, it can put your whole life on hold. With power blackouts on the rise throughout the Northern hemisphere, portable solar panels and a portable power station can be a lifesaver. If you have them prepped, you can keep your essentials running for hours on end until the grid comes back online.
Portable solar panels for home backup are an easy, affordable option to have power at hand when you need it. That being said, if you’ve got a Smart Home Panel, you can use your rooftop panels too.

Portable Solar Panels for Motorhomes
Portable solar panels are a great addition to any motorhome, van, campervan, or trailer. They provide a clean energy source and can power your entire setup when electricity is stored in a large enough battery.
Since you’ll typically be on the go, it can reduce your reliance on shore power, meaning more time travelling and less time charging up.

Things To Look Out for When Shopping for Solar Panels
Even if a solar panel is labelled as 400W – for example – it doesn’t mean you’ll be consistently generating 400W of energy. The 400W tag assumes optimal conditions, which you will not always be able to achieve. That’s why having a high-efficiency solar panel is so important.
EcoFlow’s solar panels hit 22-23% efficiency, among the highest available for any portable solar panel. The higher the efficiency, the more energy you’ll generate in sub-optimal conditions.
How To Get More Efficiency Out of Your Panels
Assuming you’ve picked a high-efficiency solar panel, you can get the most out of them by ensuring they’re clean. Cleanliness is a common issue when panels are outdoors in dusty environments. Secondly, you can ensure your panels are getting maximum sun coverage. That means as little shade as possible and angled perpendicular to the sun.
If you’re looking for a solar panel you can use with your battery, you need to make sure it’s compatible. Most solar panels use solar panel connectors and XT60 plugs. Ensure your chosen panel has these if you aim to use them with a portable power station. All EcoFlow panels support this industry standard.
Secondly, you’ll want to check the solar input of your battery/portable power station. Cheaper models tend to have low solar inputs, meaning you can only use small panels that will charge your battery very slowly. EcoFlow’s portable solar panels are widely compatible with portable solar panels and can even be easily chained together for more input.
Since they’re outdoors and facing the elements, solar panels need to be able to take a beating. Before buying, make sure you’re picking up a model that lasts. A good thing to look out for is IP rating, the qualifier in waterproofing/dustproofing electronics.
EcoFlow’s solar panels are waterproof, hitting an IP68 rating. To take that to its extreme, you can dunk them under water for 30 minutes straight, and they’ll still work. Not that you’d ever do that.
Waterproof portable solar panels
A secondary benefit to having portable solar panels with a slight flex is that they’re a tad more pliable. This helps when you’re keeping them in the trunk of your car or packing them away with a bunch of your other gear.
How To Keep Your Portable Solar Panels Safe
When transporting your panels, you’ll want to make sure you can keep them safe and secure. If you’re often moving, perhaps camping or in a van, your panels could get scuffed or even bent with rough and tumble use.
To keep them safe, it’s a good idea to store them in a case. EcoFlow panels all come with a carry case that doubles as a kickstand. It’s ideal for keeping your panels safe and secure, while simultaneously allowing you to prop them up perpendicular to the sun for optimal energy generation.

What Size Portable Solar Panel Do You Need?
When purchasing a panel, you’ll first want to consider your storage capability and input limitations. If you’re only using a small battery, such as a River 2 Pro, then you’ll need smaller panels. You might want to consider larger panels if you use a bigger battery with a high input capability.
Here’s a table that should help illustrate that the larger panel you have, the fewer panels you’ll need — depending on battery size and input.
(P.S This is just a rough recommendation assuming you want to max out your solar input).
|EcoFlow 60W Solar Panel||EcoFlow 110W Solar Panel||EcoFlow 160W Solar Panel||EcoFlow 220W Bifacial Solar Panel||EcoFlow 400W Solar Panel|
|EcoFlow DELTA mini (Solar input 300w)||5 panels||3 panels||2 panels|
|EcoFlow DELTA (Solar input 400W)||4 panels||3 panels|
|EcoFlow DELTA Max (Solar input 800W)||5 panels||2 panels||2 panels|
|EcoFlow River 2 Pro (Solar input 200W)||3 panels||2 panels|
How Much Energy Will You Be Using?
Another factor to consider when considering the size of your panel is how much energy you consume. If you estimate — let’s say in your motorhome — that you consume about 10kWh a day. Then you’ll want a few panels larger panels so that you can charge up quickly while on the road — all while accounting for unpredictable weather conditions. If, however, you only consume small amounts while in a van, you could get away with a smaller panel just to top up as and when you need it.
Is Portability More Important? Or Having Enough/Excess Energy?
Finally, you might want to weigh up portability vs excess energy. For some, it’s good to have the peace of mind that you’ll have a larger panel than you actually require at a minimum. This allows you to get a ton of solar input even in sub-optimal conditions.
For others, you’ll favour portability and staying lean for storage space and moving around.
How To Maintain Your Solar Panels
Maintaining EcoFlow portable solar panels is easy. All you need to do is give them a wipe-down from time to time to clean dust and particles off the surface of your panel. Keeping them clean ensures you’ll get maximum solar generation without obstructing the PV cells.

How To Set Up Portable Solar Panels (Series vs Parallel)
There are two main ways to set up your portable solar panels: series and parallel.
Series panels are connected in a line, with the positive of one panel connected to the negative of the next. This creates a circuit, allowing electricity to flow through the panels.
Parallel panels are connected side-by-side, with all the positives connected together and all the negatives connected together. Parallel setups take a little more time and effort, and often require accessories.
Both types of setups have advantages and disadvantages. Typically a setup in series is best for EcoFlow panels. It’s easier, and the portable power stations’ built-in MPPT solar controllers allow for optimal solar generation.
Which Are the Best Portable Solar Panels?
The quick answer is — it depends.
Portable solar panels come in different sizes for different requirements. Your solar needs depend on what you value most in a panel: portability, efficiency, durability, and compatibility.
That being said, EcoFlow makes portable solar panels of all sizes, ranging from a super portable 60W model — all the way up to a 400W model.
