Is it Really a Backpack with a Solar Panel?
Yeah, pretty much. Of course, it’s more specially designed than just slapping a solar cell on a backpack.
First, the solar panel itself is made of thin photovoltaic layers that are designed to be flexible so that they can conform to the shape of the back they are designed to go on. Also. they are designed to flex as you pack materials into the bag.
They will have a battery pack to hold the solar energy, but it obviously won’t be a large, deep cycle battery like a house solar array would use. Instead, you see some sort of power bank that will house the energy.
This power bank will either be built into a charge controller or will run to a charge controller. This will allow you to check various settings, such as how much charge the batteries still have, and will give out readings in milliamps, watts, and other common measurements.
The charge controller will also be where you plug in, either via USB or standard plug, your cell phones, cameras, laptop, and other portable devices.
Aside from the solar gadgetry, solar backpacks are fully functional bags that you can use for camping and hiking.

How Solar Backpacks Work
At the heart of a solar backpack are photovoltaic cells, also known as PV cells. These cells are made up of multiple layers of semiconductor materials, which are designed to absorb sunlight and convert it into direct current (DC) electricity.
The DC electricity generated by the PV cells is then sent to a charge controller, which regulates the flow of electricity and ensures that the batteries are charged safely and efficiently.
The photovoltaic panels used in solar backpacks are typically made from high-quality materials, such as monocrystalline or polycrystalline silicon. These materials are chosen for their ability to efficiently convert sunlight into electricity, as well as their durability and resistance to damage from the elements.
In addition to the photovoltaic cells and panels, solar backpacks also come equipped with batteries that store the energy generated by the sun. These batteries are designed to be lightweight and compact, while still providing ample power to charge electronic devices multiple times.
How Much Does a Solar Backpack Cost?
On average, a solar backpack will cost as little as $50 for a smaller model with a less powerful solar cell, or as much as $280 for a sleek design with wireless charging and removable internal dividers that allow you to convert the bag to your needs.
Oddly enough, one model that was hovering at this price DID NOT include the power bank…kind of odd for a nearly $300 bag.
Other factors are going to be the size of the bag and the materials that are used in their construction. Normal-sized camping bags are going to range in the 15-25 liter range. That’s going to be the total storage capacity spread throughout the bag various compartments and size pouches.
Larger, hiking bags are available too. These will have capacities that range from 60-80 liters, which is more in line with standard frame hiking packs.
What Can a Solar Backpack Power?
The average solar backpack is going to give you enough daily charge to get your cell phone or camera back to 100% in a few hours. How large of a battery bank you have the solar cell attached to can vary the charge time. A larger solar panel will charge the bank up a little quicker, but it will still be limited to its charge capacity.
The trick here is that if you plan to charge a laptop or have several devices to charge, you might want to bring extra banks with you.
The real question isn’t so much what CAN they charge, it’s what do you NEED them to charge?
The camping purist in me instantly says, “nothing. I’m out in nature and the whole point is to unplug from technology and the world. But I have been in some close call situation where had things gone one way I would have been in a bad situation. basically, Alaska is HUGE…and it’s easy to get off the trail and lost.
In that situation, having a solar backpack to charge a GPS unit and cell phone for emergencies is quite literally a lifesaver.
If you are a photographer or blogger who writes about nature, then having a solar backpack along on your journey means having to bring fewer storage media and batteries.
