Best Solar Panel For Backpacking

Do you remember when solar panels were ridiculously large and expensive? Thankfully, those days are behind us. Now anyone can use solar energy, which is great news for us backpackers. And now finding the best solar panel for backpacking is a whole lot easier than it used to be. For less than the cost of a good meal in Italy, you can own a portable solar panel and never worry about running out of battery power again.

Allow me to relate a personal story. In 2004, I was teaching English in South Korea. Over the Christmas break, I went backpacking through south-east Asia. My route included Vietnam, Cambodia, and Thailand. I was rocking a Blackberry 7100t, the original smartphone. That device enabled me to plan my routes, keep in touch with friends and family all over the world, stay on top of weather updates, and even purchase train and bus tickets. But all of that was useless in Vietnam and Cambodia, where chargers were few and far between. My phone was dead for most of the trip. When I got caught up in a tsunami in Thailand, I was unable to tell my family back home that I was okay. A portable solar panel would have changed all of that.

Finding the Best Solar Panel for Backpacking

Solar Panel for Backpacking being used for a trekking adventure

We are dedicated backpackers. We’re also enthusiastic about technology that helps us to backpack. Whether it’s camping overnight in the woods or trekking around the world, technology can make the journey easier and safer. Solar panels are a perfect example of this. With a portable solar panel, you will always be able to charge your phone and tablet. Your GPS will never run out of juice. You can even keep your camp lit up at night. The best solar panel for backpacking is able to charge all of your gadgets.

But finding the best one requires some digging. There are a lot of options to choose from. As the cost of cell technology comes down, more and more manufacturers are getting into the market. Overall this is a great thing. Solar panels are the most environmentally-friendly way to produce power, and competition is good for consumers. However, not all of the choices are worth spending money on. The last thing you want to do is drop $ on a solar panel that stops working after 2 charges — which is why it’s a good idea to learn about solar panels before you buy one.

What is a backpacking solar panel?

A backpacking solar panel is basically a small, portable solar panel you can use to create electricity and charge your devices. Most of them are folding three-panel units which you can unfold to capture the suns rays, and then neatly fold back up for easy storage in your backpack. Some units are small hand-held devices with a single panel. These take a lot longer to charge. The best solar panel for backpacking tends to be small enough to use easily but able to capture enough of the suns rays that it can charge quickly.

Recently, solar backpacks have appeared, which has a large solar panel built right into the face of the backpack. The idea is good because the panel will charge while you’re wearing the pack and you don’t have to do anything. Unfortunately, backpacks tend to take a lot of abuse, and these panels break quite easily. We don’t consider most of these to be the best solar panel for backpacking due to their fragility.

How does it work?

backpacking solar panel works anywhere

All solar panels work the same regardless of size. Behind the glass, which covers the solar panel, are a series of photovoltaic cells. In here, particles of light called photos are funneled where they knock electrons off of atoms. That action creates electricity. To get the atoms in there, they use opposing magnets on the top and bottom of the cell, usually silicon and phosphorous. Then, metal plates in the cell collect the electrons where they travel into wires.

Once the electrons are in the wires, normal rules of electricity apply. With large solar power units, you need a converter and an inverter to make that energy become usable for everyday electronics. Here in America, everything charges at 110-volts, so we need to turn that raw energy into user-friendly voltage. With backpacking solar panels, the converting happens inside the charging unit. When you plug your device in, the converted energy is already the right wattage and ready to go. The best solar panel for backpacking needs to be easy to use.

Why do I need one?

Because you’re traveling far from home, and often far from electrical outlets, you need to be able to keep your phone charged. Whether you’re in wooded foothills of Montana or on a train in central Europe, the ability to recharge your phone, tablet and other electronic devices can be a lifesaver. We highly recommend keeping your smartphone charged up. If you’ve downloaded maps of your travel area, you’ll be sure never to get lost. Also, the ability to call for help when needed can’t be understated.

How much do they cost?

The great news is that the best solar panel for backpacking isn’t very expensive. You can expect to pay between $ and $ for a standard backpack solar panel, and up to $$ for a premium version.

How We Reviewed

To make sure you don’t end up with a fraudulent faux-solar panel which doesn’t work, we set out to review a bunch of them for you. We want you to get the best solar panel for backpacking, and not some poorly-made piece of plastic posing as a solar panel. To do this, we found portable solar panels from all of the major manufacturers and looked at their specifications. We paid attention to several key factors:

  • The type of crystals used in the panels
  • The number of cells in each panel
  • The maximum power available
  • The age of manufacturing

Looking at each solar panel with these factors in mind helped us to determine which was real and which was garbage. But that wasn’t enough. Because we want to find you the best solar panel for backpacking, we checked out customer reviews to see what real customers had to say. If any panel failed to satisfy most of its customers, we discarded. Eventually, we came up with a decent list of solar panels you can use for backpacking.

Our List of the Best Solar Panels for Backpacking

To be honest, assembling this list was a lot of fun. Just the idea of being able to charge your LED flashlight or your smartphone from anywhere is liberating. We can recommend every single one of these solar panels, but if you’re looking for the best solar panel for backpacking, you’ll need to wait until the end of the list. Also, note that we didn’t list these in any particular order.

BigBlue 3 USB Ports 28W Solar Charger

BigBlue 3 USB Ports 28W Solar Charger

First up in our review is the BigBlue 28-watt solar charger. What we like about this system is that it has four panels in an accordion-style foldable case. There are 3 USB ports for charging, and at 28-watts, this thing will have no problem charging them all at the same time. Thanks to a polymer film over the panels, you don’t have to worry about getting them wet. They can handle light rain or mist without a problem. Best of all, it only weighs 20-ounces, which means you’ll hardly feel it in your backpack! You’ll pay between $ and $ for the BigBlue.

On Amazon, customers gave it 4.1 out of 5 stars. Many of them praised how quickly it can charge a phone. Those four panels capture a lot of sunlight, and customers loved this fact. Unfortunately, there were many complaints that it quit working on people after a month or so of usage, although not for others. Your mileage may vary.

It has a fabric case with a zipper, so it looks like a wallet. You can unzip the case, and it folds out to reveal two ultra-light solar panels.
