The 10 Best Portable Solar Panels 2022

Solar panels are changing the way we think about and use electricity. With portable solar panels that are both functional and accessible, it’s now possible to power your electronics on the go. But if you’re new to solar, then finding a portable solar panel that’s right for you can quickly become overwhelming.

That’s where we come in. We’ll help walk you through the important things to look out for, and tell you all about the best portable panels we could find.

Things to Consider in Portable Solar Panels

When buying something like solar panels, there are quite a few things you should keep in mind while shopping for the right one. Let’s look at some of the most important things to consider in portable solar panels.


Perhaps the most important thing to consider in a portable solar panel is what you plan to power with it. You wouldn’t buy a solar phone charger to power an RV, so accounting for what you’re planning to do with them is crucial.

Think about how you’ll use the panel: are you looking to keep your phone charged when the power goes out after a big storm? Or perhaps you’re looking to power a USB fan on your weekend next camping trip.

You should keep what you’ll use your solar panels for in mind, as this can help you gauge how much power you need. It can also help you figure out what kind of performance you should seek from your panels.

It’ll also help in determining what size panels you’ll need.


When you’re buying something that’s portable, size matters a lot. And solar panels are no exception.

First, if you’re going hiking or camping, you’re probably bringing other things with you. Since you have a limited amount of space, you’ll need to factor in how big the panels are when packing.

You’ll also need to consider that the size of a panel correlates to the amount of power it can generate. So, a bigger panel will typically generate more power over a given time span than a smaller panel. If you’re planning to power multiple devices, then a smaller panel probably won’t cut it.

But when we say size, we’re not just talking about length, width, and height–we’re talking about weight too.

Obviously, weight is important. If you plan to trudge through the wilderness, you’ll need to factor in the extra weight. However, it’s not always just about slimming down to the lightest panels you can find.

For example, if you’re planning on camping in an RV, you might not stray far with your panels. But you might want a heavier panel that’s more durable and won’t blow over if the wind picks up.

Peak Wattage

Another criteria in deciding which solar panel to go with is the peak wattage a panel can produce. This goes back to the earlier example of not using a solar phone charger to power an RV. You’ll need to consider how much power you need, and go around that.

However, when using the peak wattage figure, keep in mind that the number is only a theoretical maximum, based on laboratory testing. We go into this a little more later, but expect to get a maximum of 50-75% of the rated peak wattage out of your panels.

Type of Solar Cells

For solar panels, it’s important to consider the type of solar cells that make up a panel. That’s because different types of cells can generate more or less power in a given time. So let’s take a look at the three major types of solar cells and how they differ.


Monocrystalline solar panels are panels composed of solar cells that are cut from a single, pure silicon crystal. These cells offer a superior energy conversion rate over other types of cells. However, they are also the most expensive type of solar panel on the market, since they cost more to produce than other types of panels.

You can often identify monocrystalline solar panels by looking at the color of the panels. If the solar cells are black, there’s a good chance they’re monocrystalline panels.


Polycrystalline solar panels differ from monocrystalline panels in how they’re made. They use wafers of conjoined fragments of silicon crystals, rather than whole crystals.

Because polycrystalline cells use raw materials more effectively, they’re cheaper to produce. However, they’re also not as effective at converting solar energy as monocrystalline panels.

Like monocrystalline cells, you can use color to identify polycrystalline panels. Instead of black, polycrystalline cells typically have a bluish tint. However, thin-film panels can also feature this blue tint, so don’t make any hasty judgments.


Thin-film solar panels differ greatly from both mono and polycrystalline panels. That’s because thin-film panels use a variety of materials. The most common constituent of thin-film panels is cadmium telluride (CdTe).

Because of this, they are the cheapest and most flexible type of solar panels available. But they also offer the worst energy conversion rate among the three types of solar panels.

In portable solar panels, thin-film panels are most commonly found in solar phone chargers. However, sometimes there are exceptions – the Nekteck 21W Solar Charger is one such charger that actually features monocrystalline cells instead.

Now that we’ve covered some basics, let’s look at some of the best portable solar panels we’ve found.

Top 10 Best Portable Solar Panels 2022

The company also mentions that the panel is waterproof. This is a plus, considering others like the Jackery SolarSaga aren’t even water-resistant. However, there is no mention of an explicit waterproof rating. Because of this, you definitely want to avoid letting this panel get too wet.

That aside, there’s two major flaws with this panel.

The first is the lack of a kickstand. While you can improvise and set the panel against your tent, having a kickstand would greatly benefit this panel.

The second big flaw is not with the panel itself, but the charge controller that comes with it.

The charge controller that comes with the panel is only a 10-amp charge controller. However, at 200+ watts of peak power, the charge controller should be 20 amps for optimal charging efficiency.

Because of this, if you plan to use the panel to charge a 12-volt battery, you’ll want to find a 20-amp charge controller to go along with it. Otherwise, the charging performance may suffer.

But this panel is certainly a worthy contender. It has an excellent price-to-wattage ratio and provides enough versatility for a variety of use cases.

  • Peak Wattage: 6 watts
  • Size: 7.8 x 3.8 x 1.7″ / 1.4 lbs

If you’re on a strict budget and you’re looking to bring power with you on the go, then the IEsafy 26,800mAh Solar Charger is an excellent choice.

That’s because it combines the best features of other solar phone chargers on our list. Like the Hiluckey, the IEsafy panel features a built-in battery and flashlight. Meanwhile, it features an impressive IP65 waterproof rating, like the Tranmix panel.

But the IEsafy panel is larger than the others, giving it an edge over the others in terms of solar charging. It also comes with a unique compass carabiner, which could prove extremely useful when straying from the beaten path.

However, it has a couple major pitfalls. First, its exceptional battery capacity doesn’t seem to match its real-world performance. Rather, it has a relatively short battery life for 28,500mAh.

The other issue is not an issue with the product itself. Rather, the issue lies in how it’s marketed, and how most people perceive “fast charging.”

The company claims that it features two fast charging USB ports. Technically, at a max power output of 5 volts/2.4 amps each, that’s true. But fast charging is commonly used synonymously with “Quick Charging” or “Power Delivery.” But both standards offer charging at a higher voltage or amperage than this panel.

Of course, if your device doesn’t support these new charging standards, this is a non-issue. But if you have the latest Samsung Galaxy or iPhone, just know that this panel doesn’t offer that extra bit of charging power you might think it does.

Still, with the things it does right, it’s hard to overlook this panel. And you can’t forget that it’s offered at an exceptionally affordable price point


  • Larger solar panels than other comparable models
  • Built-in battery and flashlight
  • IP65 waterproof rating
  • Comes with a unique compass carabiner
  • Exceptionally affordable


  • Battery life isn't stellar
  • “Fast charging” isn't what you might think it is

Everything You Need to Know About Portable Solar Panels

portable solar panels

We’ve looked at some of the best portable solar panels we could find. Now, let’s get into some more in-depth topics, such as figuring out how much power you’ll need from your solar panel and how to take care of them.

Figuring Out How Much Power You’ll Need

As we mentioned earlier, figuring out how much power you need from your solar panel is an important consideration to make on shopping for one. But figuring out precisely how much power you’ll need is complex and requires a sophisticated approach to accurately gauge your power needs.

Gauging Your Expectations

First, you’ll need to factor in all the electronic devices you plan on powering over a given period. You’ll need to start by gauging the amount of power each device uses, and how long you plan on powering them.

To figure out how much power a device uses, there’s a couple of ways you can go about it. One way is to consult the manual. This should give you an idea of what kind of wattage each of your devices requires to run for a single hour.

Another way of figuring out how much power a device uses is by using a power monitor, such as a Kill-A-Watt monitor, to read and record power usage in real time. This is by far the most effective way to measure the power requirements of your devices and offers a more reasonable real-world estimate.

Plan for the Time You Expect to Use Your Devices

Once you’ve gauged how much power your devices use, then figure out how much you plan to use them. So if you’ve determined that your laptop uses 50 watts an hour, then you’ll need to figure out how much time you plan to use it while you’re out.

But estimating the time you plan to use your device isn’t the only thing you should plan for. There’s a lot you have to look for.

Expect the Unexpected

Sometimes things take a turn for the worst, so you’ll want to factor that into the equation.

For example, say you’re planning a weekend camping trip. You expect to use most of your time hiking, fishing, or hunting, while your solar panel charges your laptop back at camp. However, you may find your trip dampened by an unexpected thunderstorm, forcing you to stay inside at camp.

Now your solar panels are now effectively useless until things clear up, and you now decide to use your laptop while you wait for the storm to blow over.

Obviously, the more important your electronics are, the more important it is to prepare for the worst. That could mean bringing an extra pre-charged battery bank, an extra set of solar panels, or maybe even a small gas generator for backup if you absolutely need electricity.

How to Clean Your Portable Solar Panels

Solar panels are frequently exposed to the elements. But portable panels are unique in that they’re exposed to so much more than rooftop panels; fingerprints, spilled drinks, and muddy adventures, to name a few.

Keeping your solar panels clean is an important part of maintenance, though it’s also easy to overlook. But, before you haphazardly reach for your cleaning chemicals, take a moment to learn how to properly clean them, so you don’t accidentally damage them.

Cleaning Your Solar Panels

The first thing you should do is disconnect the panels from any devices you have the panels plugged into. If possible, you’ll also want to disconnect the charge controller from the panels. Next, bring them inside or to an area where they won’t get any direct sunlight to stop them from charging.

Once they’re disconnected from any electronics and out of the sun, grab a soft cloth. You’ll want to dampen the cloth with a low-mineral water, such as distilled or ionized water. Using regular tap water can leave mineral deposits behind, which will cause your panels to become cloudy.

You’ll also want to avoid using hot or cold water, and to ring out any excess water before you clean your solar panels. This will help prevent water from making its way inside the panels.

Wipe or gently scrub the panels with your damp cloth. Take care not to push too hard when wiping, as too much pressure may cause the solar cells to crack. Once you’re done wiping the panels, follow up with a dry microfiber cloth to soak up any excess moisture, in order to avoid streaking and water spots.

What About Cleaning With Chemicals?

You want to avoid using any kind of cleaning solutions on your solar panels. That’s because many chemicals contain micro-abrasive detergents or solvents that can damage the surface and cause the panels to cloud up.

But we aren’t just talking Windex and rubbing alcohol here – this includes soap as well, since it often leaves behind a film of its own.

If you have sticky residue that won’t come off with water alone (such as tree sap), then you might use a small amount of gentle dish soap and water to clean the area. But even then, you’ll still want to proceed with caution, as doing so may void the warranty on your solar panels.

Why Don’t My Solar Panels Reach Their Advertised Charging Output?

The peak wattage rating any given solar panel has is its theoretical maximum, based on laboratory testing. The actual energy output of a solar panel largely depends on the amount and intensity of light hitting the solar panel, as well as changes in lighting over time, and the temperature of the panels.

Your geolocation and the time of year also play a large part in determining the power your panels can actually generate.

What that means is that real world numbers are far more likely to be in the 50% to 75% range of the stated maximum output. So a 100-watt solar panel is likely to generate somewhere between 50 and 75 watts of power.

Of course, it is possible you may have a defective solar panel. One way to check this is by using another panel with similar specs at the same time to see if it puts out a significantly different amount of power.

In any case, it’s important to remember to temper your expectations. With so many variables at play, you’re highly unlikely to get the stated maximum output out of your panels in a real-world environment.

Tips for Getting the Most out of Your Solar Panels

There’s a lot of variables that factor into the efficiency of your solar panel that are completely out of your control. With that said, let’s look at some things that you can control, that will get you the most out of your solar panels.

Use Solar Panels Under Direct Sunlight

Solar panels work best when they are outside under direct sunlight. While they will work in the shade or behind a window, these obstructions can greatly diminish the efficiency of any solar panel.

Keep All of Your Solar Panels Uncovered

Many foldable solar panels require that each panel remains uncovered to work properly. If you find your panels aren’t charging at all, make sure each panel is fully uncovered and exposed to direct sunlight.

Keep Your Solar Panels Clean

Keeping your solar panels clean is another way to ensure they work as they should. In case you missed it, we covered some cleaning tips, so you can keep your solar panels clean without damaging them.

Try to Keep Your Solar Panels Dry

We all know water and electricity don’t mix. Many portable solar panels offer water-resistance, but few offer any meaningful waterproofing. Because of this, it’s important to keep your solar panels and their charge controllers as dry as possible.

Don’t Bend Your Solar Panels More Than 30 Degrees

Many portable solar panels are thin and come in cloth cases. However, you should still take care to not bend your solar panels any more than necessary. Bending them by more than 30 degrees can cause the cells to break, rendering them useless.

What Is QC 3.0 and PD 3.0 USB?

You may notice when looking at portable solar panels that some panels come with PD 3.0 or QC 3.0 USB charging ports. But what does that mean?

PD stands for Power Delivery. QC stands for Quick Charging.

Each standard offers unique benefits depending on your device. But both charging standards offer a common benefit over regular USB 2.0 charging ports: higher power output. This means that if your device is compatible with either charging standard, PD or QC 3.0 ports will charge those devices more quickly than standard USB charging ports.

Wrapping Up

Finding the right portable solar panel for you can be overwhelming at first. However, knowing what to look for and how to plan accordingly is helpful for finding the right panel for you.

Once you’ve picked your solar panel, all that’s left to do is plan and prepare for that epic family camping trip you’ve been wanting to take. After all, who doesn’t like a little fun in the sun?
