Finding the Best Portable Solar Panels - Buying Guide

Choosing a portable solar panel that will suit your needs certainly isn’t rocket science. However, it’s easier to end up with the best possible device when you know what to look for. Have a look at some important factors that you should keep in mind while shopping:

Things to Consider When Choosing the Best Product

Usage

When shopping for portable solar panels, one of the first things you need to consider is its future usage. As you’re looking for a portable model, you will obviously want something with low weight. However, that’s not the only thing to keep in mind.

As a portable device, your solar panel/charger will also need to be resistant to the elements. If you’re a hiking or biking enthusiast, there’s a good chance your model will come into contact with water or dust. Choosing a waterproof model, but also one that’s resistant to corrosion and dirt should be among your top priorities.

Finally, make sure to select a unit with some kind of a hanging/attachment contraption. These include things like carabiners or hooks. As you can already guess, they allow users to hang the panel on their backpacks, letting them charge their gadgets on the go.

Versatility

You will also want your solar panel to be versatile. When speaking about versatility, we’re mainly thinking of wide compatibility. As you’ll be dependent on your solar charger during your outdoor adventures, you’ll want to select one that’s compatible with most of your gadgets. You don’t want to buy a model that’s limited only to your phone.

Another thing that can make a particular model versatile is the presence of an ammeter. Portable solar panels with built-in ammeters are, actually, widely available. An ammeter will help you find the best position for peak functionality. It will show you the ampere output once you start charging your gadget.

However, it’s important to mention that some of the best portable solar panels are already versatile in nature. Unlike their roof-mounted counterparts, they can be taken anywhere and used for a myriad of purposes. Most can be folded or come with special cases, making the transport effortless.

Technology

When it comes to off-grid and grid-tied markets, crystalline technologies remain the most popular. These hold the most substantial chunk of the market.

They are separated into monocrystalline and polycrystalline modules. However, once we take into account the already-mentioned importance of efficiency values, it’s easy to see that monocrystalline technology is the best for portable solar applications.

Another solar panel technology that needs to be considered is the thin-film. It seems like the perfect solution for portable systems, as it is both compact and very flexible. However, thin-film technologies come with a significant downside. Although maneuverable, thin-film panels have much lower efficiency values than their monocrystalline counterparts.

If you have the money, try to obtain a monocrystalline model. The cells used in these panels are cut from a single silicon ingot. This, among other things, allows them to run in the range of ~20% efficiency. Polycrystalline models, on the other hand, rarely go above 16% efficiency.

Efficiency

Another crucial thing to look for is efficiency. When it comes to solar panels, efficiency values show how good a particular model is at converting sunlight into usable electricity. Once the sun’s power becomes this usable electricity, it is sent to the model’s circuit box. A person then uses this electricity to charge his/her gadgets.

Typically, efficiency is expressed as a percentage. Imagine two solar panels – they look exactly the same and are of the same size. However, the first one has an efficiency percentage that’s higher than that of its counterpart. This means that the first model can produce more electricity – it’s as simple as that.

Generally speaking, most of the modern models are far more efficient than their old predecessors. Selecting a solar panel with a higher efficiency value means that you’ll be able to get more electricity out of it for the same size.

Important Features to Look For

When shopping for a solar panel, you will want to know the power size of your future model. When it comes to these devices, their power output is typically shown as wattage. This term combines two different variables - current and voltage. As you can see in our roundup, most of the best solar panels and chargers we've analyzed have the wattage of around 20-30 Watts. For a portable unit, this is more than enough - you'll be able to charge all of your electronic gadgets on the go. Things are a bit different from large, stationary models - their power output is greater, which is why they have a higher wattage.

Some models of solar panels come with integrated batteries. As you can already guess, these allow one to store electricity converted from sunlight for later use. To put it simply, a unit with an integrated battery extends the use of generated power. Integrated batteries are not that common with portable solar panels, though. With these devices being used primarily on the go, there's no real need for them to hold a charge. If you really want to save some solar power for later, you can simply use your solar panel to charge a standard power bank.

Contrary to popular belief, solar panels actually have a meager weight. This is particularly true for portable models. Goal Zero Nomad 7, for example, weighs only one pound. This makes it super compact and easy to carry around, which is very important for everyone who uses these devices while traveling. When you're hiking, your backpack is probably already packed with all sorts of items. You don't want your solar charger to add any significant extra weight. Models that can be folded are especially convenient - once folded, they take even less space and are easier to store.

Fortunately for all those who don't like messing with complicated gadgets, portable solar chargers are extremely easy to use. Most models don't sport any bells and whistles - just the basic functionality of charging your smartphone, tablet, camera, and other devices. The only thing you really need to care about is the placement of the gadgets you'll be charging. Many electronic devices won't charge if they overheat. A good way to prevent this from happening is in using long charging cables. By using one of those, you'll be able to place your gadget away in a shady spot.

How to Set Up Your Portable Solar Panel?

With your portable solar panel, you’ll be able to charge multiple devices. However, it’s important to understand how to set up your device in the correct way.

Let’s say you’re on a camping trip. You have your portable solar panel, a set of wires, a charge controller, a battery pack, and an inverter. Once you’ve determined the power size, you’ll need to establish the connection in a parallel or a series – this depends on the voltage and current requirements of your charge controller. While the parallel connection adds current, the series connection adds voltages.

Once you’ve connected the terminal outputs, you’ll also have to connect the charge controller input to each terminal output. Connect your terminal outputs to the energy storage device. While doing this, you’ll need to make sure that the controller’s voltage output is the same as the battery pack’s nominal output. Once you’re done with establishing the battery connection, you’ll be able to wire the power AC loads to the battery-based inverter.

Things are much less complicated with the best portable solar panels that are designed to charge phones and similar devices specifically. They look appealing and are very easy to use, letting one charge his smartphone via USB ports.

Designs vary from best solar panels that look like tablets to those that fold down like an accordion. Some models allow charging multiple gadgets at once, such as your Bluetooth speaker, external battery, Go Pro camera, and others.

As always, carefully reading the instruction manual is a surefire way of setting up your panel correctly. If you want our advice, this is probably a good idea when it comes to other products as well. If the instruction manual is not available for any reason, the manufacturer’s website should provide all the necessary information on how to set everything up correctly.

Q:

How to use portable solar panels?

Even though portable solar panels may seem complicated at first, you’ll be surprised at how simple they are to figure out once you get to it. Again, the instruction manual is your friend here; follow it carefully and you should be all set. 

Once you have the device set up, you should be able to connect the cords to your home, camper, RV, or boat, and that’s all there is to it. The device will begin to convert sunlight into energy as soon as you have everything ready. It’s all surprisingly simple. Just don’t forget to leave the panel out in a sunny area. 

Conclusion

Choosing the right portable solar panel for your needs can be a daunting task. To make things easier, try to figure out what will its purpose be and go from there. Do you always need a fully charged phone on your hiking trips? Or are you running a mobile office and always need to have a few different devices charged?

As you increase the wattage, the price will go up, but so will the efficiency. It all depends on your needs and your budget. As you can see in our lineup, each of the portable panels and chargers we’ve reviewed excels at something. This should help you choose the one that suits your requirements.
