Solar Backpack
Solar powered backpacks are an excellent way to save and utilize energy outdoors. Millions are already advocating energy-efficient techniques of living to save the planet. You can do your part by utilizing solar energy to charge your gadgets.
The modern human cannot survive without electronic gadgets. There is just a pressing urgency to remain connected to the world, at the expense of money and the Earth’s energy. Since it’s already hard to take away gadgets from the person, the best compromise is to advocate environment-friendly ways of maintaining this gadget.
The solar powered backpack is a very good investment because it’s a one-time, big-time purchase. Once you’ve bought the backpack, you can charge your gadgets using the backpack whenever you want to as long as there’s energy stored in the battery cells. You only have to pay for the backpack. You can forget about paying for electricity and hurting Mother Earth.
How Solar Powered Backpacks Work
You need to understand solar technology to get a deeper understanding of the mechanics behind a solar powered backpack. Solar technology is made possible by photovoltaic or PV cells. PV cells located on the solar panels gather light energy from the sun. With the help of a semiconductor, the gathered light is converted into usable electricity. The semiconductor material is usually silicon. However, since silicon is reflective, it doesn’t really absorb the rays of the sun. The silicon semiconductor is usually coated with an anti-reflective coating so that the semiconductor doesn’t lose too much energy.
The silicon absorbs sunlight energy when the sunlight shines on the solar panel. The electrons in the silicon flow around freely when the sunlight hits them. The electricity of the photovoltaic cells pushes the shocked electrons of the silicone towards one direction. The flow of electrons creates an electric current that can be collected with attached metal points found at the opposite ends of the PV cell. The energy is stored in batteries and can be used later on.
Solar powered backpacks have little solar panels attached to them. These solar panels collect the rays of the sun. This little piece of solar technology makes it possible for you to charge your gadgets such as your mobile phone, PDA, and mp3 player. If you expose the solar panel of a regular solar powered backpack, it can collect enough energy to charge a mobile phone for a little more than an hour. Solar powered backpacks are good for outdoor use because they’re really light and waterproof.
Choosing the Solar Powered Backpack for You
Upon entering the department store to look for a solar powered backpack, you will probably be swamped with different offerings from salesmen of different brands. If you’re a heavy-duty user of gadgets who’s always on the go, you might want a backpack that can store the excess power that you do not currently need. You can use the free power later on. In this case, you might want to consider getting an extra battery pack. If your backpack can hold at least 15 watts of power, then you’re good to go.
Since solar power is all about using energy wisely, the solar panels attached to it should ideally be recyclable. Aside from that, they should be high-efficiency panels. Outdoor use of the backpack should make the panels waterproof and scratch-resistant.
Some people use solar powered backpacks for business and professional use. If this is so, you may want to get a bag that has a storage space for laptop. This means that the panels of the bag have to be padded for protection. In the end, it’s all about choosing what fits your lifestyle.
