7 Best Solar Backpacks | March 2017

We spent 35 hours on research, videography, and editing, to review the top options for this wiki. Instead of worrying about running out of juice when you're out and about, get a solar backpack and keep your electronic devices charged up no matter where the trail takes you. These bags look so good and work so well, in fact, that it would be a shame to use them just to power up your smartphones or tablets when camping or hiking. Why not use one every day and do your bit for renewable energy? Skip to the best solar backpack on Amazon.

Power In The Days To Come

Look to the horizon, and tell me if you don't read apocalyptic omens there. If you don't, you're not looking hard enough. Of course, the impending collapse of functioning society as we know it isn't the only reason for you to invest in a solar backpack, but it is the most exciting to talk about.

Sure, you might want to keep your camera and cell phone batteries charged when you're hiking in beautiful wildernesses, or be able to rely on a constant, free source of power when hopping around from country to country without a converter, but isn't it more thrilling to think that this backpack might someday not only be a convenient source of natural power, but also your only source of electricity?

Either way, the solar backpack is a life saver. By simply adhering a series of solar modules to the back and top areas of a simple backpack, these manufacturers have turned your carry-all into its own veritable power plant.

To understand how these packs work, it helps to understand how solar panels work. Essentially, a solar panel is comprised of a ton of little power pods called PV (photovoltaic) cells. These cells work like Velcro in a sense, as they each have a complimentary side to them, one negatively charged, the other positively charged.

The respective charges of each are the result of doping either side (both of which are silicon-based) with either boron or phosphorus. When boron and silicon combine there are holes left over by boron's deficiency in the valence electrons needed to form bonds to other substances. When phosphorus and silicon combine, the opposite is true, and an extra electron exists where the atoms meet. Thus, the boron-doped silicon carries a positive charge, where the phosphorus-doped silicon carries a negative charge.

In the space where the two sides meet, the extra electrons on the phosphorus side jump over to fill the holes in the boron side, creating an electrical field in the space between, called the depletion zone.

When a photon of light passes through a PV cell's depletion zone, it knocks an electron loose of its hole and either side will scramble to balance the depletion zone back out, ejecting the free-floating electron toward and along a metal wire, forming the electrical current.

How Far Will You Go?

Choosing a solar backpack may seem like an aesthetic decision at the outset, and it's true that you want a pack that you'll actually be willing to wear out in the sunlight. Otherwise, you might as well pick up a simple backpack without any of that glorious solar technology to it, and that would be a shame.

Once you've narrowed down our list to a smaller number of stylishly pleasing packs, you can start to evaluate them based on their features, and the features that will be most important to you depend on the distances you plan to travel.

If you're going for longer stretches without access to reliable electricity, you'll want to focus on a pack that can produce more juice than its competition from less sunlight, and ideally one with an internal power reservoir for storage. These tend to be a little heavier than the charge-as-you-go style of bag, but they prove more useful in the long run.

You might just want to keep your phone charged while you're on the go in another country, though, just to make sure you have enough power to run any apps you need for navigating foreign soil. The smaller, lighter bags with just a panel and a plug will probably be enough for you.

Power Pulled From The Sun

While a French physicist named Edmund Bequerel first made note of a photoelectric effect in 1839, the first photovoltaic module as such wouldn't come into existence until Bell Laboratories built it in 1954. Of course, this was well after Albert Einstein won the Noble Prize in 1921 for his work on the photoelectric effect among other things.

Those early modules made by Bell and others were small and pretty inefficient, with short lifespans and grotesque price tags, but they were necessary to the development of the much more durable, less expensive solar technology we use today. Another big boost in the development of solar technology came from NASA in the 1960s, who began using solar power on their spacecraft and satellites in earnest.

In recent years, the vast majority of research into solar electricity has been geared toward the consumer market, with companies offering to share in the investment to help offset initial costs to homeowners.

In the public sector, you'll already have noticed the inclusion of solar arrays on street lamps and road signs, and that's just the beginning. A small portion of America's iconic Route 66 roadway is getting a huge solar makeover, replacing its pavement with a special, experimental solar street which is designed to power nearby communities while directly melting ice on roadways and providing driver feedback about animal crossings, accidents, and more.
