The introduction of smart backpacks to the backpack industry has largely contributed to An adult wearing a solar panel backpack which answer the question what is a solar powered backpackthe technological changes we see in a backpack and one of these technological changes is the introduction of solar panel backbags.

Before you know how to build your own solar panel bag, first you need to understand exactly what they are.

What is A Solar Powered Backpack?

A solar panel backpack or a solar-powered bag is a type of pack equipped with thin film solar cells or solar panels and batteries capable of converting the sun’s energy into electrical energy.

In some cases, the solar thin-film solar cells or solar panel and batteries come with the pack while in other cases only the solar panel is included with the bag.

What this means is that you would have to get your own battery if you intend to store the current to use for a later purpose.

How Exactly Can A Backpack Store Current?

Now what you need to know is that the current does not exactly come from the backbag itself but rather it comes from the solar panel which was attached to the bag.

The sun produces solar energy and when these solar energies come in contact with the solar panel, they are converted into electrical energy which is then stored in the batteries.

Like I said, some packs come with batteries that are connected to the solar panel used to store electricity but if yours doesn’t come with a battery such as a power bank then you might have to get yourself one.

The solar panels are able to charge your devices without making use of any battery to store the converted energy as long as the panels are under the sun but if you intend to use the energy later on then you would have to store it in a device capable of storing electrical energy preferably a power bank.

The power bank can then later be used to power up or charge your appliances.

Advantages Of A Solar Panel Backpack

1. They are powered by a constant source of energy which is the sun

The sun is considered as one of natures most constant sources of energy available to anyone that intends to make use of it. It is totally free energy and can be used to power your devices when converted using a solar panel.

2. They are lightweight, hence easy to carry

Because of the type of panels used on bags, they can be pretty light which therefore means they add very little weight on the bag making them very easy to carry.

3. Some solar panels can be manually removed from the bag and used separately

Not all bags with solar panels are able to do this because they probably were built in a way that makes it difficult or nearly impossible to remove them from the back bag.

However, the way some of these panels are attached to the bag makes it pretty easy to remove them from the bag and probably place them where there is better contact with the sun’s energy

4. Flexible solar panels also are light and portable, as well as waterproof

Disadvantages Of A Solar Powered Backpack

1. They can be pretty pricey

The higher the quality the more expensive an item is. The same is true for a solar bag. For those of you planning to get one with really good quality, you should be ready to spend more than $100.

The really good ones cost way more than that. Do you feel that this is not an option? Then considered building your own solar bag. This is a very cheap option and anyone should be able to do it.

2. There are not a lot of options to pick from

These type of bags have not always been around and are kind of limited in supply. You won’t even find them in some countries and are mostly accessible through online purchases.

Luckily there are some brands strictly focused on creating solar bags so hopefully, we should be able to see more of them in the market pretty soon.

3. It has to be under strong sunlight before it can be able to function properly

This can be a major disadvantage of this type of bag because if they are not under strong sunlight then they would not be able to properly function.

4. The angle of the sun might not directly face the solar panel of the pack

The backbag is always meant to be at your back so what happens if the angle of the sun is not directly facing your back. This can be a problem especially when carrying your pack and can actually make the panels not to function properly.

If you would be able to hold your bag with your hand then you should be able to position it in an angle whereby it can be able to properly face the sun.


A solar panel backpack can be used for several reasons

1. It can be used to power a laptop for up to 3 hours depending on the type of solar panel being used

2. After exposure of about six hours, it can power an emergency light for 14 hours

3. These type of bags can be used to power cameras for use in remote areas

4. They can be used to power electronic devices for up to 6 hours

2. Get the required equipments

Aside from getting the solar panels you would need to get the required equipments which are

  • epoxy glue

3. Know the length of your bag

You would need to measure your bag so you know its length. By knowing its length you would be able to know the number of panels you would need that can properly fit your backpack.

You would need to drill holes on the plexiglasses because you would need to screw them together later on. Drill 4 little holes at the corner of both plexiglasses.

5. Assemble the panels

Your next task would be to assemble the panels by making use of the adhesive tape. Use the adhesive tapes on the back of the panels and attach them to the plexiglass. Make sure they don’t cover the little holes that you drilled. You then apply the glue and make sure the panels are properly stuck to the glass and then allow to dry for about an hour.

6. Connect the wires

After allowing the glue to dry up your next task would be to connect the wires and the usb port if the panels don’t come with a usb port. Also, connect the adapters that you wish to include.

7. Make use of the other plexiglass

After connecting the wires, use the second plexiglass and place it on the side of the panel without plexiglass making the drilled holes align together. After doing this you then put the nuts on top the holes and screw them together.

8. Attach To Your Backpack

The best way to do this is to sew a patch to hold the panel and then you would have to attach the panel in its patch to the part of the backpack you feel would be more exposed to the sun.
