The solar backpack (solar folding bag) looks the same as a normal backpack in appearance. But the difference is that it has a solar panel on the front. This solar panel absorbs solar energy and converts it into electric charge. At the same time, it stores the absorbed charge in a generator box.

The factors you consider when buying a solar backpack are different from ordinary bags. You should consider the following factors for a solar backpack:

1. Types of solar panels

Monocrystalline Silicon: These are made of a single large silicon crystal. Monocrystalline silicon panels are arguably the most efficient because they can generate a lot of electricity even in the absence of sunlight. In terms of efficiency, monocrystalline silicon solar panels are the best. Although they are the most expensive of the three types, they are generally the most durable and the least sensitive to high temperatures.

Polycrystalline: Polycrystalline silicon solar panels are usually laid on a large area and are composed of multiple silicon blocks. They take up much less space than amorphous silicon panels and are less expensive than monocrystalline silicon panels. They don't generate as much electricity as monocrystalline silicon panels, but they're still a good investment for a home or RV.

Amorphous silicon: Also known as thin-film solar panels, the flexibility and flexibility will be much better than polycrystalline silicon and monocrystalline silicon, allowing more installation options. On the negative side, they take up about three times the space of polycrystalline and monocrystalline solar panels, produce only so much electricity, and some will cost more per unit than solar panels.

2. Efficiency

Efficiency values refer to the amount of solar energy converted to direct current. They are usually displayed as a percentage. Higher efficiency means the panels weigh less and take up less space, but still have a solid output. Make sure you get solar panels that maximize energy output without taking up too much space. It is important that the power output exceeds what you need to power your electronics. Also consider what climate conditions you will be using it in. Efficiency is even more important if you can't guarantee constant exposure to sunlight.

3. Power (wattage)

Higher wattage means the panel is better able to power several electronics at once. Typically, higher wattage means a better efficiency rating, but also a higher price point.

4. Weight

It has a lot to do with the type of trip you're going to be doing and where you're going to put your solar backpack. If you're going hiking, you should be looking for the smallest solar panels you can find so you don't get dragged down. If you're just putting her in the RV, there's not much to worry about.

For ordinary solar backpacks, you have to consider the following points:

1. Appearance

Does it look good, and does the color and shape match your style of clothing?

2. Capacity

Whether it can meet the daily necessities you carry

There are not many differences between solar backpacks and ordinary bags. It’s just that solar backpacks need to consider the solar panels in the front, and it has some advantages over ordinary solar panels. It has the storage function of ordinary bags and can charge mobile phones and other electronic devices at the same time. If you want to know more about solar panels, please leave a message and contact AES PV Technology Co., Ltd., which is a professional manufacturer of solar panels.
