The demand for solar panel backpack is gradually increasing primarily because of a number of instabilities that we are currently experiencing in our environment. A number of these instabilities are causing a direct effect on the power supply of various countries around the world even those dependent on nuclear energy. Moreover, this type of energy source provides ample power to those who choose to live in the wilderness or go outdoors every once in a while for relaxation and commune with nature.
Unfortunately, despite the desire to go hiking or live outdoors, many people simply cannot survive without their precious gadgets. These hallmarks of modern life need ready source of power once their batteries begin to die down. The solar panel backpack is one of the most practical solutions for this problem because it relies mostly on free solar energy, which is converted to usable electricity capable of powering and charging other devices for considerable number of hours.
However, you must be aware that not all solar panel backpacks are made the same, which is why you must take into consideration the following tips:
- Built in solar panels
The design of the solar panel backpacks may differ substantially depending on its manufacturer and intended functionality. When shopping around, make sure to look for one that has the solar panels built into the unit to eliminate potential problems like damaging the panels or charging capability of the unit. This also makes it easier for you to simply pack up and go without forgetting to install the solar panels.
When in the market for a solar panel backpack, keep in mind just how much power you will normally need. This would allow you to decide on precisely how big the panels would need to be including the storage capability of its battery. Keep in mind that the power ratings for these units can be distinct, which is why you must base your decisions based on your practical power requirements. Please also note that not all solar panel backpack models include a battery pack.
- Flexibility of battery chargers
There are some units that have been designed to recharge specific types of batteries such as AA or AAA batteries for example. The reason is that these are the most common types of batteries used by the majority of devices in the market today. Even portable mobile phone chargers powered by either of these two types of batteries can be bought to transfer power to the battery of your mobile phone for example.
Therefore, it would be ideal to shop for solar panel backpacks that have more flexibility in the types of batteries that they can charge. For one, this eliminates the need to carry additional battery chargers, which may prove to be too bulky and impractical. If you can find a unit that is capable of powering and charging majority of your devices, then this would be the best type of solar powered device for you.
One last bit of information to consider when deciding on a solar panel backpack is the battery packs capacity. For the typical smart phone such as an iPhone the capacity of its battery is 1,400 mAh. Ideally you would want to choose a battery pack that is at minimum 2,000 mAh. Most beginners would think that if their device has a 1,400 mAh battery than that is the capacity of battery pack they need to fully charge their device. This is completely false. You need to consider that for example an iPhone even at idle is still using up battery life for tasks such as incoming sms messages or radio signals. If you would want to fully charge your device such as an iPhone I would make sure to purchase one with a minimum of 2,000 mAh.
- Consider mobile solar panels
Many people who buy a solar panel backpack believe that it is enough for all their needs while on the trail. Unfortunately, they find out later on, that they need more power than they had planned for, or their units are not storing as much solar power as they would want. This is where the foldable solar panels can be used to resolve your problem. Aside from being completely functional, they remain easy and convenient to carry.
By simply hanging them across your solar panel backpacks, you will gain additional panels to allow you to harness more solar energy and at a shorter time. One of the advantages of these types of panels is that they can be arranged in a way that they can capture more energy from the sun. There are those with clamshell designs that feature a hard outer shell, which would be ideal when on the trail where equipment abuse can be expected.
- Direct power connection
One of the best choices when it comes to solar panel backpacks is those that have been designed to connect directly to the devices that need to be powered using a USB connection. This allows the solar power source to function similar to a wall outlet in the home where electricity flows directly to the device being charged or powered. The device may not be charged completely by the solar panel, but it will keep it running continuously.
The reason to look for this feature in a solar panel backpack is that it is extremely useful when in an emergency and you suddenly find yourself running out of batteries for you mobile phone or GPS device for example. Usually, this feature is available only for smaller devices and may not be powerful enough to apply to laptops and similar devices that require higher power deliveries.
- Weather proofing
Many buyers of solar panel backpacks often forget the fact that one of the most important features to look for in this unit is weather proof. You cannot discount the fact that when in the wilderness, you will not have control of the weather. This means that it can be sunny at one time and then suddenly you will experience rain. If you buy solar panel backpacks that are not treated for waterproofing, the rain can ruin your unit altogether.
The first solar panels: Initially, when solar panels were introduced they were unstable and required to be installed in special casings, which in turn limited their capabilities severely. With the improvements in technologies, solar panels are now made with thin-film materials that allow for more opportunities for use. It also means that solar panels are now more flexible not only in their use, but also where they can be implemented.
Undoubtedly, this is one important factor that you should look for in solar panel backpacks. There is no question that you will be using the unit outdoors more than indoors and quite possibly in rough terrain. Although these rolled panels are made of a solid material, the durability can be significantly different from one manufacturer to another.
It is important to note though that there is no glass component, which means that nothing will break. Most are likewise tolerant to different temperatures and weather, so choose based on the type of environment you are most likely to use it in.
Solar power undeniably is an extremely stable source of alternative energy. In order to maximize the benefits derived from it, you must have a device that will not only harness it properly, but also serve your needs correctly. Following these six buying tips will ensure that you get the best solar panel backpack for your requirements.
