What Is A Solar Backpack?

The solar backpack is a backpack with a solar panel system. It comprises solar panels, LiFePO4 Battery, charge controllers, cables, and individual layers, making it ideal for hiking, camping, and travel. Its photovoltaic panels are mounted on the top or back of the backpack and generate electricity whenever it is exposed to full sunlight, which is used to power electrical devices such as phones, tablets or other electronics. After power supply, it can store excess power in mobile solar cells, allowing users to have sufficient power supply at any time.

How Does A Solar Backpack Work?

Most of the photovoltaic cells in a solar system backpack can produce 120 watts of electricity per day and are the energy converters for the entire power generation system. It produces electricity through the photovoltaic effect, also known as the internal photoelectric effect. When sunlight shines on a solar cell, the cell absorbs light energy and produces photogenerated electron-hole pairs.

Under the action of the built-in electric field of the battery, they are separated, and there is an accumulation of charges of different signs at both ends of the battery, that is, a photogenerated voltage is generated. If electrodes are drawn out on both sides of the built-in electric field and a load is connected, current will flow through the load, thereby obtaining power output and completing the conversion of light energy into electrical energy. The power generated by the electric panel can be directly stored in the battery, and can also be integrated into the power grid through the inverter to dispatch and use the electric energy.

Features Of Solar Panel Backpack

Solar Powered: The monocrystalline silicon solar panel of the solar backpack is assembled from several monocrystalline silicon cells on one board. The photoelectric conversion efficiency reaches up to 24%, and the charging conversion efficiency is higher than that of polycrystalline solar panels. It can absorb solar energy more quickly and convert it into electric charge to quickly power devices in times of emergency and avoid users losing contact with the outside world.

Multi-Level Storage Space: The solar backpack's multi-layer construction design allows it to have multiple pockets, including side pockets, interior as well as exterior pockets. These bags help users organize and place various digital products and daily necessities needed for travel in a neat and reasonable manner, so that they can be found quickly when needed.

Removable Battery Panel: Parts of hiking solar backpacks have removable solar panel that is attached to the backpack using hiking buckles. They can be removed from the pack at any time and placed on the surface of the tent or on the grass to get more sunlight, so that they can build up power faster. When the user is on the move, the panels can be mounted to the surface of the backpack to store power without interfering with mobility.

Imbricate Structure Technology: The solar backpack's battery panels use shingled structure technology with a honeycomb pattern on the surface to make the connections between the battery sheets closer. This kind of battery uses active materials to replace lead, and increases the content of the electrolyte and the surface area of the electrode, making it highly transmittable, which can increase photoelectric conversion by 5% and has a light-concentrating effect.

Waterproof: The backpack is protected from the potential effects of rain and snow, keeping your electronics and personal belongings dry and safe. It's made with waterproof materials and lining, such as 300D polyester and 600D Pu, as well as double-stitching and stress-point reinforced construction technology, making it waterproof, abrasion-resistant, and tear-resistant.

External USB Port: The solar backpack's USB charging port is located on the side, bottom, or above the shoulder straps of the backpack, allowing you to charge a variety of electronic devices while on the go without taking off the bag. It has a waterproof design with a silicone lid for a tight seal.

How To Use The Solar Backpack For Charging?

1. Users can directly connect the device to the USB port on the solar backpack for charging. This usage is especially suitable for situations where users need electricity urgently or the mobile power supply runs out of energy, which is faster and more convenient.

2. Users can first let the solar backpack fully charge the mobile power supply, and then charge the mobile phone through the fully charged mobile power supply. This method is especially suitable for cloudy days and insufficient solar energy. When the mobile power supply supplies power to the device, the solar backpack's panels can store electricity at the same time to prepare for the next power supply.

Energy Independence

A solar backpack stores excess power after your device is charged for next use, so you don't have to scramble to find an outlet or charging station.

Application Scenarios

1.Traveling: it powers travelers' small batteries, cell phones, cameras, and other USB devices.
2.Commuters: to charge their tablets, cell phones, computers and other devices during their commute.
3.Outdoor activities: the backpack provides emergency backup power to keep radios, broadcasting devices functioning to maintain contact with the outside world.
4.Remote areas: it powers medical equipment for public service workers and devices that do not have access to utility grid power.
5.Schools: The solar backpack can be connected to a TV or projector that can display a lesson or PowerPoint on a large screen, providing children with the opportunity to learn from online videos, digital tools and data.

Warnings:

1.Avoid using solar backpack in extremely hot or cold weather.

2.Do not expose its charger to direct heat or sunlight.

3.Do not abuse, knock or damage the battery.

4.Watch for any warning signs: A buzzing or hissing sound from the battery panel may indicate a damaged or failed battery or panel.

5.Make sure the battery is fully charged before use to avoid affecting the power output.

6.Do not let the entire solar panel be immersed in water.

7.Regularly clean the surface of the solar panel and recharge the battery.
