Written by Bradley Page

As I am sure you already know a solar panel is a device designed to absorb the sun’s radiation as a source of energy, for generating electricity or heating. Now, a portable solar panel is this device that can be moved, transported and can also be easily powered.

For a hiker or a camper, the best portable solar panels have the ability to power and recharge batteries for a wide range of devices. The best part with these contraptions is that you can choose to go solo or link several panels together for maximum energy, depending on your needs.

Important features to consider

If you consider improving your next outdoor expedition with one or more portable panels, it’s important to know what you want. Below we’ll discuss some of the most important features that must be included in the decision-making process.

Ease of use

A portable solar panel must be easy to install and operate since you don’t have a specialist with you. Everything must be as simple as opening the panel, placing it in the sunlight, and charging your devices. No fuss, no complicated instructions, no brain teasers.

Just think about this situation: your phone is dying and you need to call for an emergency situation or you need to check your GPS coordinates. In such a situation, you need access to quick energy and you don’t have the time or the will to decipher complicated instructions.


You don’t need a panel that will weigh you down as you go up the path – after all you might be climbing a very steep mountain! If you are biking, hiking, or even rock climbing, your panel shouldn’t weigh over one pound. It must also be quite easy to make small and stuff inside the backpack.

However, if you are boating or driving, weight doesn’t really matter so you can go wild with your choices. Still, some of the models we’ll discuss today can be used on a backpacking trip and on a boating trip.


This means that your panel must be easy to move around and transport. As you will see, the models in our reviews can be easily folded up and carried around without worries about damages suffered during transportation.

Most models today can charge more than a certain type of phone or tablet. Due to the smart charging technology available today, most models can understand the devices you’re trying to charge and can offer the right amount of electrical power. This makes portable solar panels extremely versatile and quite easy to have around.


The most sought after accessory is an external battery (I think you can imagine why). However, there are other things to consider like standing supports that allow you to position the panel easier, hooks so you can hang it over your backpack, pockets that protect your devices, cables, adaptors, and others.

Just take a look around and you’ll see a wide range of accessories. Still, make sure you only buy the ones you need so you won’t load you backpack too much.

A few final words…

  • Maintenance has zero costs.


  • The main disadvantage is that energy cannot be created during the night time.

    The Instapark Mercury Panel has been a really reliable charger for me. I’ve used it in weather as cold as 15 degrees and up to 80 degrees and it has been able to charge two Novabeam batteries (in full sun) in three hours or less. This panel works without having to take a lot of special care, though you might still want to dust the panels off a little bit when you use it.

    These solar panels are really something! The newer batch have become thinner, sleeker and more powerful than ever. I remembered when the solar panels are nil – we had to carry tons of batteries for out cellphone so we can charge them easily. Those were remarkable days indeed!

  • Michelle Decker

    We are extremely happy with the Bigblue 28W Outdoor Charger 3-Port that we bought this year. Even late in the day, we were able to get a really good charge out of it. The flexible strap points on it give it more flexibility to attach it to a tent, tree, backpack, etc. It’s a really good choice if you’re looking for portable solar panels!

    Thanks for your great comment on the product. I often wondered how we got along without solar panels in the past! Imagine how many batteries campers and trekkers bring with them in order to charge their basic gadgets.
