Benefits of Solar Panels For Backpacking
- Lightweight and compact design. A key virtue of solar panels for backpacking is the fact that they fit in with any gear. You can tuck them into your backpack. Most come with a protective layer to prevent scratches. Since they are neither bulky nor heavy, you can tow them with you almost effortlessly.
- Environmentally friendly energy. Harnessing the sun’s rays to convert into power for your devices is one of the most ecologically forward ways to get power. Instead of relying on fossil fuels or the chemicals in batteries, you can limit your carbon footprint without foregoing convenience.
- Safety while hiking and backpacking. Nature walks have inherent risks. The ability to access GPS, cell-phone technology and even email can make this a lot safer. Solar panels give you the chance to explore the wilderness without being out of touch with the outside world.
- Works in conjunction with other gear. A solar panel can complete your setup for outdoor travel. When used in conjunction with a quality sleeping arrangement, you can take longer trips and have them be more enjoyable.
- Cost-effective power solution. Instead of paying for batteries for your flashlight or GPS, you can save the expense and rely on solar energy instead. Though it may take some time, it is lighter than batteries and costs less as well.
- Long-lasting appeal. Solar panels are pretty hardy. They are designed to be moisture-resistant and usually have a cover to protect them from impact. Most aren’t too vulnerable to wear and tear thanks to quality circuitry. This means the panels will provide a reliable charge over the long-term.
Types of Solar Panels For Backpacking
This type of solar panel is one of the most common for backpackers. It is designed to spread out to maximize surface area when in use. After you are done, it folds down compactly and can be placed easily in a backpack. Most of these accommodate standard USBs. Others can work with micro-USBs and DC outlets. Generally, these consist of two or three panels that work together to catch the sun.
The most compact of solar panels, you can find handheld options that are only a few inches across. These are designed for small-scale use and are generally suited for those looking to only charge a smartphone. In most cases, these will have only a USB or a micro-USB port. Though efficient, the small size means fewer rays are caught. It can take a while to get an effect out of a handheld model. As a result, it is best as an emergency or survival tool.
This refers specifically to the kind of solar technology used in the panel itself. The monocrystalline is constructed using a single crystal, usually made out of silicon. It is very pure; and, as a result, highly efficient. This piece is cut to form cells, much like in natural tissue. It takes in the sun's rays quickly and offers a high level of efficiency.
Another type of solar technology, this kind of panel consists of several different small pieces of silicon. These different parts are placed together like cells. This forms the solar panel. Generally, these are effective, though have less efficiency than a monocrystalline option. As a result, they are less costly. However, they are often less compact making it ill-suited to backpacking.
Perhaps the least common type of solar panel, the thin film is made out of various semiconductors that are placed on a backing. Usually, the back is made out of glass or metal, though there are polymers as well. Lightweight and flexible, this type represents some of the more expensive tech on the market. Despite being easy to maneuver, this type of panel is more vulnerable to scratches.
Opening its doors in 2010, Renogy began as a student project in Louisiana. Since that time, it has become a common name in the field of energy efficiency. With solar tech available in all sizes, this brand remains a strong competitor in the industry. A popular offering from this brand is the Renogy Eclipse Solar Panel.
After commencing operations in California in 2015, Jackery quickly became an international name. Starting with the first-ever portable lithium power station, it expanded its offerings into renewable power sources. One of this company’s leading offerings is the Jackery Solar Saga Portable Generator.
Solar Panel For Backpacking Pricing
- Under $50: In this range, you are most likely to find handheld options and smaller folding selections. Usually, they can charge one device at a time.
- $50 and up: Solar panels in this range are almost always monocrystalline in design. They have a big surface area, overheating safeguards, and can charge multiple devices.
To gather and process solar energy, the panels are essential. Either this tech will be monocrystalline, polycrystalline, or thin film. The most common is monocrystalline. Depending on the structure, size, and design, efficiency can get to over 23 percent. The more efficient the panel, the more quickly you can get the charge you need. Larger panels can be bulkier, though tend to work more quickly.
To charge your devices, you need to be able to connect them to the power source. Most solar panels feature a standard USB outlet. While some have multiple outlets, it will always reduce each device’s access to power when multiple pieces are charging. There are also panels with micro-USB attachments and those which offer DC outlets. Ensure that the devices you plan to charge are compatible with the panel.
Since backpacking is mostly outdoors, the safety features are essential to the lasting performance of the device. An important feature is the ability to resist water. While most aren't waterproof, a certain amount of moisture-resistance is very helpful. Secondly, quality panels feature smart-charging tech. It optimizes the amperage for each device. This charges the piece more quickly and prevents circuitry damage and overheating.
The backing may seem like a small feature, but it goes a long way to protect the panels from scratches and damage. If the panel has a sturdy enough backing, you can place it on the ground directly. Otherwise, it needs mounting hardware. Usually, the backing is polymer and nylon. It keeps water away from the outlet. It also helps in the event the panel gets dropped and to prevent overheating in general.
- Weight and Size. When you pick your solar panel, keep an eye on the size. You want something that folds out to give you a large surface area. This catches sunlight well. However, it should also fold down to be small enough to fit into your backpack. Since you’re going to be hauling it everywhere with you, opt for something light enough to tow easily.
- Maintenance Needs. Especially when you’re out in nature, you want low-maintenance tools on hand. Though all tech requires a certain level of upkeep, it is more convenient to choose something less demanding. Find a solar panel that is easy to clean and comes protected against scratches and moisture damage.
- Time to Charge. Pick something that charges your devices quickly. Choose a device that is easy to set out in the sun without causing overheating damage. Ultimately, you want to consider your amperage needs. Pick a solar panel that has a higher amperage rating and an overall high efficiency. These two aspects of the panel will determine how soon your device can be working again.
- Durability. The goal is to have a lasting power source. To get this out of your solar panel, you want something tough. Choose something that comes with a case or has a strong protective backing. Consider how sturdy it is, both when folded and when expanded. By opting for something that isn’t prone to overheating and is water-resistant, you can slow wear and tear.
- CompatibilityF. inally, consider the devices you are going to have plugged into the piece. Think about the kind of charger you need to use for them. Is it a micro-USB or a standard one? Perhaps you need a DC outlet. Whatever the case, be sure that the panel can provide sufficient amperage to the device. Also, make sure that you can plug it into the panel itself.
