However, you don’t want to buy a panel that’s bad for you. In fact, you don’t want to buy a panel at all if you don’t need it. So we’ll make sure that you don’t make that mistake. In this article, we’ll be covering your options of buying portable solar panels, defining exactly what they’re good for and how you can use them, and which one you should get. Let’s get started!
What Features Should I Look For When Buying Solar Panels?
Portable solar panels are a great alternative to regular electricity, and more and more people have started to take notice.
Before we begin listing all of the panels you can get, let’s take a look at some of their features. We’ll be differing the panels by type and defining the quality of each panel.
Materials and Technology
Different types of portable solar panels were created by using different technologies and materials. The most popular portable solar panels are crystalline panels, which are used in both off-grid and on-grid solar panel systems. Crystalline panels usually come in two different subtypes: monocrystalline and polycrystalline. Monocrystalline models are more efficient than their polycrystalline counterparts, meaning that they get more energy from the same amount of sunlight. They’re also more expensive.
Next, we have the thin-film panel, which is sometimes called the amorphous silicon panel. These panels are cheaper and less efficient, but this is because they’re very portable and flexible. They’re also foldable, so you won’t have any problems with finding room for these panels.
Efficiency
Efficiency should always be your top priority when you’re looking for a portable solar panel. This tells us the rate that the sunlight converts energy to the DC current that powers our homes and appliances. If you take two identical portable solar panels, with the only difference being that panel A is more efficient than panel B, panel A is going to collect more energy than panel B, within the same time period and while being just as large. In this context, efficiency means quality, and that’s what you should always aim for.
Weight
Weight shouldn’t be too much of a problem if you’re travelling with a vehicle, but if you’re going on foot, then it could be a key feature. You need to choose a light yet reliable model, otherwise you’re defeating the whole idea of portability. If you’re on the move constantly, then having a foldable and portable solar panel can be a lifesaver. It won’t take too much room in your pack, and you’ll always have power with you.
There are some differences when it comes to how much power you can get from a solar panel. Obviously, solar panels have major differences in size, and different sizes of solar panels offer different outputs of energy. Generally, the larger the solar panel, the greater the amount of sunlight it can absorb. This will result in a larger energy output.
Temperature Impacts
Something worth mentioning is that solar panels tend to function better in cooler areas (contrary to the popular belief). Areas that keep the temperature at 20 degrees Celsius or less are better for solar panels. However, warmer areas don’t really take away too much – solar panels are only 0.3% less efficient in warmer areas.
Your needs will define the differences between the solar panels you’re using. There are panels that can be secured to the top of your RV, there are panels that you can take camping, and there are panels that can power entire camping sites. You’ll need to take your needs into account before making a decision on this.
The most important thing with solar panels is placement. You don’t want any part of your panel to be in the shade. You don’t want dust to get on it either. Clearly, you can’t control the wind, so make sure to clean your panel if you notice any dust on it.
Utilization
It’s important to think clearly about how much energy you’ll need to produce. You don’t want to buy a portable panel that won’t allow a large enough output of energy. You also don’t want to waste money on a panel that’s producing energy in excess. This will mean that you can’t spend as much energy as your panel is producing, so you’ll ultimately overspend.
You can easily calculate how much power you’ll need by adding up all of your appliances’ power draws, often shown on the products’ labels. The amount of energy your panel can produce is usually defined in the description.
You’ll need to know what you’ll be using it for in advance. Boats and RVs demand much larger systems than what you’d need for a single camping trip. Going camping is completely different from going on a trip with your RV or boat, and usually requires less power. You’ll need to know how much wattage you’ll need, and you shouldn’t buy a panel that goes below that value.
The main selling point of solar panels is that they can charge your batteries anywhere, as long as they have access to direct sunlight. There are also many panels that have batteries included, so they’re able to store the energy they collect. You’ll be able to use it later on, even when the panel isn’t charging. This way, you can have power even during the night. They’re also pretty silent, so they won’t keep you up at night.
Stationary Solar Panels Are Cheaper Than Portable Solar Panels
Portable panels are usually cheaper than stationary panels, typically costing less than $100, with stationary panels costing more than 100$.
Another thing you should know about panels’ overall efficiency is that they can’t collect 100% of sunlight that they face. They can usually only absorb about a quarter of that energy, with the best solar panels absorbing 23% or more. Lower quality solar panels absorb about 20%.
Also, most solar panels only have two USB ports for charging, with the odd panel having three ports. They also usually have only 2.4 amps of power, which will charge your devices slowly. Only the highest-end panels have higher amperage and can charge your devices quickly.
Ease of Installation
Make sure that the panel you’re buying doesn’t require a master’s degree in engineering to install. There are many panels that are easy to use, sure, but there are also many panels that require an entire team to install.
Find panels that don’t require any special skills or special tools instead. This information is usually printed on the packaging or in the description of the product. There are panels that are simply rolled out or unfolded, and there are panels with adjustable stands.
Now that we’ve covered everything, let’s take a look at our choices for the best portable solar panels.
1. Renogy KIT-STARTER-100D – Best Overall
This portable solar panel system is actually one of the best in the world. Its wattage adds up to 400W, so you won’t have to worry about powering several devices at the same time. It will power up your RV in no time.

4. Jackery SolarSaga 100 W Portable Solar Panel – Best Value
This panel is going to give you a great value for your money. Jackery is widely known, in solar panel circles, as one of the best companies in production of solar panels. They’ve been developing solar panels and other green energy solutions since 2012, and this solar panel system is no different.
Portable Solar Panel Features
This panel weighs in at just under 10 pounds, and is 23 by 20 inches in size. It’s very portable, and the comfortable handle allows for easy folding and carrying. The 100-Watt module implemented in the design separates into two panels. The panels have a kickstand that allows them to be positioned on any surface at a 45° angle. This is great because the panels can face towards the sunlight, which can and usually will make the difference between having enough energy and having a lack of the same.
Another amazing feature worth mentioning is the fact that this panel has the highest conversion available – 23%. Remember when we talked about conversion and efficiency? We highlighted that panels can only use about a quarter (or in some cases: a fifth) of all sunlight they receive. We also noted that only high-end panels can achieve 23% or more. Well, this is one of those panels, when we’re talking about efficiency – this is about as good as it gets.
With this panel, you get two USB ports, so you can charge both smartphones and small electronics. One of the USB ports is USB-C (5V/3A), and the other port is a USB-A port (5V/2.4A).
Portable Solar Panel Benefits
You can combine this solar panel with Jackery’s Explorer 160/240/500/1000 power station (sold separately), which is suitable for unexpected power outages and outdoor life.
This solar panel is also very durable, since ETFE material covers its surface, ensuring its longevity. This is also the reason for higher light transmittance and its weight. It can operate at temperatures as low as -10 degrees Celsius, and as hot as 65 degrees Celsius. One thing to keep in mind, though, is that the solar panel is not waterproof (unlike many other waterproof panels that we’ve mentioned), so it’s not suitable for boats.
This panel is also one of the most highly rated solar panels on Amazon, with 86% of ratings being five-star ratings (at the time of writing), out of 1540 worldwide ratings and reviews.
The panel is very easy to set up and to use, and connecting it to any Jackery’s Explorer power station isn’t difficult either. This panel, however, isn’t really something that you can fit into your backpack or something similar.
It’s something you can transport in your vehicle and keep in your home. We still think that it’s great for camping, it’s just not that portable and flexible, that’s all.
