How We Chose the Best Solar Backpack

We took a look at the power output of the solar panels, the size of the solar backpack, and the overall design quality.

We considered the unique use of the bag so that not every solar backpack on our list is the same.


Solar backpacks are usually equipped with detachable solar panels ranging from 5 watts to 12 watts.

If a backpack solar panel is less than 5 watts, it will take too long to charge your device’s lithium ion battery. The higher the watts, the quicker the charge time.


Standard backpacks range from 8L to 100L, and most solar backpacks range around 20-25L. This is enough space to carry your essentials and for your charging devices.

REMEMBER that the larger the solar backpack and solar panel, the more weight you’ll be carrying on your back.

Look for padded shoulder straps to make the weight easier to bear.


We took a look at the overall quality of the solar backpack and solar panels. We chose the solar backpacks we felt were constructed well and would last long.

Having durable solar panels is important to avoid damage and malfunction. You do not want to deal with broken solar panels in an emergency.

Reviewer Opinions

Reviewers are happy with their Voltaic System Array backpacks. They claim that the battery bank and high capacity solar panel work as advertised.

These solar backpacks are capable of charging DSLR camera batteries, a separate power bank, or an external laptop battery.

Travelers have taken their bags as far and wide as France and West Africa with no issues.

Some buyers complain that this solar backpack is too bulky for urban environments. Others complain that the solar panels will not work in shade or overcast weather.

In our testing we found that this is a standard issue for most solar energy devices, so we aren’t particularly disappointed with any of the solar powered backpacks in this way.

Features & Considerations

Voltaic Systems makes a range of solar backpacks, but the Array model outshines the rest.

With 3 monocrystalline solar panels and a 19,8000 mAh battery pack, the Array can charge smartphones, tablets, laptops, DSLR cameras, and more. 

The biggest selling point for this solar backpack is its ability to fully solar charge a laptop in one go.

The panels boast a 19% efficiency rating and can charge 7 smartphones, 3 tablets, or 1 laptop when the solar power bank is full.

The power bank offers USB, and Hi-Voltage laptop outputs that are FAA compliant for carry-on luggage. 

The solar backpack offers some waterproof fabric and weather-resistant solar panels to your expensive tech.

It’s a 25L clamshell design complete with a 15-inch laptop sleeve, 10-inch tablet sleeve, and dedicated smartphone and battery pockets.

You can easily squeeze in enough gear with room to spare, but the empty backpack weighs in at a hefty 5 pounds.

The Winner

Our testing concluded that the Voltaic Systems Array Rapid Solar Backpack Charger is the best option on this list.

Although it may be the most expensive, it features everything you would want in a solar backpack.

It has space, a long charge time, is durable, and is waterproof.

How to Choose the Best Solar Backpack

Choosing the right solar power backpack for you may be a bit difficult. To make it easier, we feel you should consider how and why you’ll be using your backpack.

Cargo load and charging capabilities are some of the most important features to look at before purchasing.

What Will You Be Using Your Solar Backpack For?

What you’ll be using it for may determine the wattage of the solar panel, the size of the bag, the material and design, and the extra features.

Some common uses are traveling abroad, hiking, professional photography, commuting, and more.

For those using their bags to commute to work, touring a foreign city, or carrying books to class, a lightweight bag with a low wattage solar panel and anti-theft protection is perfect.

Having an external USB port is convenient for charging phones while walking around. Weatherproofing is ideal but not essential.

If you’re a professional photographer or digital nomad, you will want to get a backpack with plenty of space for equipment.

A clamshell bag design is great for this, and anti-theft protection can be an added touch of security when carrying expensive equipment around.

You’ll want a high-wattage solar panel to charge multiple devices at a time.

And for those looking to hike, camp, or prepare for an emergency, a durable bag with weatherproofing and a detachable high-wattage solar panel is perfect.

You’ll want a backpack with the highest quality solar panels and a backpack made from the best materials.

It’s better to spend more money on a top-tier model in this case.

What Devices Are You Planning To Charge?

Most buyers only want to charge small devices, like smartphones or iPods. Any backpack with a solar panel above 5W can reasonably accommodate small devices in full sun.

It will take a few hours longer to charge in cloudy conditions, so an external battery bank is essential for power storage when the light is dim.

Some backpacks come equipped with battery banks, which is good to consider.

You will want more power if you’re planning on charging high-capacity devices. A 10W panel is enough to charge a laptop, but it will take several hours.

These devices require adapters and power banks as they don’t charge via USB.

Most backpacks aren’t suitable for fully charging a laptop and are instead used for smaller devices.

There are few models and brands that can accommodate such power-hungry electronics, but they will cost upwards of $200.

Are You Getting A Backpack For Outdoor Activities?

You may need extra features such as suspension systems, hydration bladder, or waterproof fabrics.

Having a smaller backpack would be a better option, so you are not carrying as much on your back.

A small daypack will be the best option for those who are doing strenuous activities such as running or cycling.

These bags are lightweight, made with breathable mesh, and fit close to your body. Some come with hydration bladders and waterproofing.

If you plan on doing long-distance hiking or camping, you’ll need a large bag that can protect your devices from the elements. This may include waterproof material or built-in rain covers. 

Having a detachable solar panel is useful because you can tuck it away when you feel it may get damaged, or you can leave it out in the sun for charging.

What Size Solar Backpack Do You Need?

The interior of a backpack is measured in liters (L). This indicates the maximum volume of the bag or how much stuff you can reasonably fit into the bag.

Some companies factor in extra side pouches or compartments, while others calculate based on the bag’s dimensions.

A backpack usually ranges between 15-25L. It’s enough room to carry a laptop, some books, a water bottle, a few pieces of clothing, and other miscellaneous items.

Most buyers prefer this because it is practical and can carry enough.

Smaller backpacks range around 8-10L and can only handle small loads up to a few pounds. These are great for athletes, cyclists, or those on hiking excursions. 

Long-distance hiking backpacks range from 30-100L and can carry a large amount of equipment such as camping supplies.

If you’re planning on hiking for more than a few days, you’ll want a minimum of 60L capacity.
