Whether you're planning a driving trip, a sailing adventure, a beach vacation, or a camping trip, charging electronic devices in remote areas can be a challenge. Solar energy is an excellent, eco-friendly option for keeping power on the go, but traditional panels are bulky and designed to be fixed in one place. However, there are now tons of portable solar panels that are lightweight, powerful, and built to withstand the elements. They're also compact enough that you can store them in case of an emergency power outage.
How do I use a folding solar panel?
Portable solar panels can charge devices directly, or they can charge batteries or solar generators. Some panels can be attached directly to a cell phone or small device to charge it when the sun is out (the panel must face the sun). However, direct charging from the sun can be inconsistent. It is better to use solar panels to capture energy and store it in some sort of battery (such as a solar controller, battery bank, or charging station), and then connect the device to the battery - especially with more robust panels.
We have categorized a wide variety of products to find the best portable solar panels.
Power Output
When buying a panel, consider how much you need to calculate what size panel you need. A small device like a cell phone will be fine with a 15-watt panel, while a larger device like a cooler will require a larger panel (and usually a battery to store the energy). Wattage refers to the maximum DC output under optimal conditions, but keep in mind that cloud cover can prevent it from reaching maximum output.
Durability.
Since you're probably planning to take the panel with you when you travel (or at least move it around the yard), you'll want something sturdy, weather-resistant, and compact so it can be stored and transported easily. Keep in mind the type of traveling you'll be doing: If you're hiking and carrying your gear, the lighter the panel, the better. Heavy-duty latches, rust-resistant materials, protective glass, and reinforcing components are important to the longevity of the panel.
Size and Weight
Depending on how you travel and the amount of storage space you have available when you're not using it, the size and weight of your solar panels are important factors. Many panels can be folded into easy-to-carry cases, but if space is limited, you may need something smaller. While nylon-cased panels may be lighter, they may not be as durable as panels with metal frames. If you just want to power the light without needing to charge the device, then you're better off with a lightweight solar light.
Compatibility of the device
Finally, think about the panels you want to charge with and check if your solar panels are compatible with these devices. If not, you may need to purchase additional cables or adapters. Many of these panels are designed to be compatible with batteries and rechargeables made by the same manufacturer.
