Complete Buying Guide for Best Solar Panels For Backpacking
Essential Factors We Consider
Choosing the best solar panel for backpacking boils down to four key things: weight, power, durability, and portability. Weight is critical; every ounce counts in your pack. Look for panels under two pounds. Power output, measured in watts, determines charging speed. For a phone, 10W is slow but usable, while 20W-30W is much faster. Durability means waterproof ratings like IPX7 or IP68, which protect against rain and dust. Finally, portability is about how small it folds and if it has carabiners or a pouch for easy carrying.
Budget Planning
Solar panels for backpacking range from about $50 to over $200. Set a realistic budget. For occasional weekend trips, a budget-friendly 10W-20W panel may be enough. For longer adventures or charging multiple devices, invest in a mid-range 25W-30W model. High-end 35W-40W panels offer the fastest charging but at a premium. Remember, the goal is to match the panel to your actual power needs without overpacking or overspending.
Final Thoughts
Always test your solar panel at home before a big trip. Understand how it performs in different light. Pair it with a reliable power bank to store energy for nighttime use. And don’t forget: solar charging is slower than a wall outlet. Patience and proper sun angling are part of the off-grid experience. With the right panel, you can enjoy endless views without worrying about a dead battery.
Frequently Asked Questions
Q: How long does it take to charge a phone with a solar panel while backpacking?
A: It varies widely. Under full sun, a 10W panel might take 4-6 hours to fully charge a modern phone, while a 30W panel could do it in 2-3 hours. Cloud cover, panel angle, and phone usage during charging will all affect the time.
Q: Can I use a solar panel to charge a device while walking?
A: Yes, many panels are designed to attach to your backpack. However, charging will be less efficient if the panel isn’t facing the sun directly. It’s best for trickle-charging a power bank throughout the day.
Q: What does the IP rating (like IP68) mean on a solar panel?
A: IP stands for Ingress Protection. The first number (6) refers to dust resistance (6 is total dust tightness). The second number (8) refers to water resistance (8 means it can withstand continuous immersion in water). For backpacking, IP67 or IP68 is ideal for heavy rain.
Q: Do I need a power bank with a solar panel?
A> It’s highly recommended. A power bank stores the solar energy, allowing you to charge devices at night or when the sun isn’t shining. It also protects your devices from potential voltage fluctuations from the panel.
Q: Are foldable solar panels durable enough for rough handling?
A> Most quality panels are made with durable materials like ETFE laminate and have reinforced stitching. However, they are still electronic devices. Avoid sharp bends, keep them clean, and store them in their protective case when not in use to maximize lifespan.
Embracing solar power can transform your backpacking trips, giving you freedom from wall outlets and dead batteries. Whether you choose the powerful BigBlue 35W, the efficient ELECOM NESTOUT, or the budget-friendly BigBlue 25W, you’re investing in more time enjoying the trail.
