Back in “ye olden days,” hikers and campers explored the backcountry (and sometimes even the front-country) without the luxury of modern electronics. They were forced to rough it with only the most essential camping gear, sans smartphones, FaceSpace, and Wordle. Thankfully, those days are in the past—and now, we’re living squarely in the future. Even the hardiest, weight-conscious backpackers are toting some form of electronics into the wilderness, be it an outdoor watch, a digital camera or just an iPhone for emergencies.
Most campers these days—whether car camping, RV’ing, or overnighting in the backcountry—are carrying more than a handful of electronics. All those gadgets demand power, and it’s still hard to find electricity when you’re camping. That’s where solar power comes in. Today’s portable solar panels and solar generators have the capacity (literally) to allow us to stay off-grid almost indefinitely—and some, you can even carry on your backpack. But, the dizzying list of specs—wattage, amperage, energy efficiency percentage—and buzzwords like “monocrystalline” and “ethylene tetrafluoroethylene coatings” can be confusing. That’s why we’ve done the legwork for you to round up the best camping solar panels of 2022.

Are solar panels on campers worth it?
If you spend time camping and traveling in an RV, a solar panel setup can be a cost-effective, environmentally friendly, and convenient way to use electricity on the go. Solar panel systems generally require little to no maintenance and provide a dependable source of electricity when the sun is shining
How many watts of solar do I need for camping?
If you have a single 12 volt battery, at about 100 AH, you should have 300 watts of solar panels, minimum. With two 12 volt batteries, or two 6 golf cart volt batteries, with between 200-250 AH, you should have 400 watts of solar panels, minimum
Best Solar Panels for Camping of 2022 | Outdoor Life
The Best Solar Panels for Camping of 2022 Updated Aug 1, 2022 10:07 AM Experienced campers know that you can get off the grid without having to ditch your electronics if you bring along a great solar panel that’s built for camping and outdoor environments. Modern panels have come a long way since the low amperage models of even a few years ago and with the right setup, you can power anything from a laptop to an electric cooler, with nothing more than a clear view of the sky on a sunny day (sometimes you don’t even need that). To find the best solar panels for camping, I put high-performing models from the top brands to the test: Best Overall: Anker 625 Solar PanelMost Stable: Jackery SolarSaga 60Best for Chaining: Goal Zero Nomad 50Best Crossover: GoSun SolarPanel 30Best for Smartphones: BioLite SolarPanel 5+Best Budget: Anker 515 Solar Panel Things to Consider Before Buying a Solar Panel for Camping How Solar Panels Work At its most basic, solar panels are made up of solar cells that convert sunlight into electricity. Each cell has two conductive layers, in between which are two different types of silicone—one with extra electrons, and one with space for electrons. When sunlight hits a solar panel, it sends a photon slamming into a solar cell, which in turns knocks one of the extra electrons loose. When that electron makes its way over to one of the silicone layers with space for electrons it creates a positive charge on one side and a negative charge on another. The solar cell channels the movement of the electrons, so that it can capture the energy it produces as it moves. While the amount of energy captured by each solar cell is negligible, when strung together in a solar panel, it can be quite impressive, with some of the solar panels in my test able to produce as many as 100W. Some solar panels are better at regulating this output of energy than others, which matters when you are trying to capture this energy on the other side, whether in a power bank or directly into a device like some of the best solar generators. For instance, if you try to charge your smartphone on a port that can output 20V of power, then there is a good chance that you’ll damage the battery of your phone, even if in the moment it appears that your phone is simply charging extremely quickly. The solar panels in my test limited the voltage output from the USB ports (5V or less), while the DC ports, which are intended to pair with one of the best power banks for camping, provided a higher voltage output (between 14.5V and 26.5V). While this provides some protection against accidentally overcharging your devices, it’s still worth knowing how the max voltage output of each solar panel port compares to what your device’s or power bank’s battery can handle. Power Output While there are differences in the power ratings between solar panels, generally speaking, the larger a solar panel is, the more power it will generate. This is why solar panels for camping are typically folded twice or more—to maximize the amount of surface area they can cover when in use, while also minimizing the amount of space they occupy during transit.

Best Portable Solar Panels for Camping in 2022
Best Portable Solar Panels for Camping in 2022 The best solar panels for camping are now incredibly affordable. You can easily find a quality solar charger for recharging smartphones for under $50. Or, you can go all out and spend several hundred on a top-of-the-line setup that pairs portable solar panels with a portable power station. Today, I’m going to break down all the different options. We’ll start with my top recommendations for both solar chargers and solar panels in 2021 before moving onto a basic rundown of what makes these solar power devices tick. Best Portable Solar Panels and Solar Chargers for Camping in 2021 $35.99 $49.99 in stock as of September 3, 2022 1:28 pm $62.91 in stock 9 new from $62.91 as of September 3, 2022 1:28 pm $71.96 $79.99 in stock 3 new from $71.96 1 used from $60.59 as of September 3, 2022 1:28 pm $129.99 in stock 1 used from $97.91 as of September 3, 2022 1:28 pm out of stock as of September 3, 2022 1:28 pm We’ve done the legwork for you by reviewing dozens of the top solar panels and solar chargers over the past couple years. Here are our top picks for 2021. 1. BigBlue 28W Type: Solar Charger The BigBlue 28W is our favorite solar charger for camping in 2021. Not only is it affordably priced, but it’s durable, reliable, and has one of the fastest charging speeds of any solar charger. The BigBlue 28W boasts 28 watts plus a large surface area for a quick charge. It features SmartIC Technology to detect exactly which type of device you’re using to deliver the fastest charge possible. Two USB outlets let you charge two devices at once. This BigBlue camping solar charger is known for its durability. It’s made from high-quality, waterproof materials to prevent damages. It’s our favorite solar charger for camping in the rain. This device’s only downside is its weight. It’s not huge by any means, but at 24 ounces, it’s a little too hefty for most backpackers. 2. X-Dragon 40W Type: Solar Charger The X-Dragon 40W is a fantastic solar charger for those planning to charge laptops while camping. Because it’s so powerful, it’s quite large. It’s pretty dang heavy and also quite bulky, which makes it best for car camping only. The large size does have its benefits in terms of performance. The 40 watt output capacity and large surface area make the X-Dragon ideal for charging smartphones, laptops, and more. As a solar charger, the X-Dragon doesn’t have a built-in battery. For best results, we recommend pairing it with a portable power bank or power station. This allows you to recharge your devices at night. We definitely recommend this camping solar charger for car campers, vandwellers, and the like – but we recommend backpackers steer clear of it. 3. Goal Zero Nomad 10 Type: Solar Charger The Goal Zero Nomad 10 is our favorite ultralight solar charger for backpacking. It weighs in at just 1 lb 1.6 oz total. A compact, foldable design complements this lightweight construction. Fold open for a larger solar surface area or fold closed to stash in your pack. A weatherproof outer layer helps the Nomad 10 excel in lackluster conditions. Designed to shed rain and snow, you can even use this portable solar charger while camping in the winter. As the name implies, this Goal Zero portable solar panel boasts an output capacity of 10 watts, more than enough to efficiently charge smaller devices like smartphones, GPS units, and headlamps. Additional highlights include the built-in LED indicator that displays current solar strength and an included kickstand to achieve an optimal charging angle (and provide a shady place for your charging devices). 4. Goal Zero Boulder 100 Type: Solar Panel The Goal Zero Boulder 100 is my favorite portable solar panel for charging portable power stations. As the largest device on our list, this solar panel is best for car camping only… In fact, the Boulder 100 is a top choice for solar for RVs, camper vans, and other vehicle dwellers that want a portable power setup. Unlike a solar charger,…

The 7 Best Portable Solar Panels of 2022 We independently research, test, review, and recommend the best products—learn more about our process. If you buy something through our links, we may earn a commission. Treehugger / Chloe Jeong Whether you’re planning a road trip, sailing adventure, beach getaway, or camping trip, keeping electronics charged up in remote areas can be challenging. Solar energy is an excellent, eco-friendly option for staying powered up on the go, but traditional panels are bulky and designed to stay fixed in one place. However, a large number of portable solar panels are now available that are lightweight, powerful, and built to withstand the elements. They’re also compact enough that you can keep them stored away for use in the event of an emergency power outage. We’ve sorted through a variety of products to find the best portable solar panels. Courtesy of Amazon For a portable panel that’s ideal for van life and recharging RV or boat batteries, the Renogy folding 100-watt panel is built to withstand the elements. It tops our list because it’s a versatile, sturdy, and efficient panel at a moderate price. Measuring 40 inches long x 27 inches wide (when open), the panel is extremely efficient—even in low-light areas or cloudy days. The unit includes a corrosion-resistant aluminum stand and a rugged protective case with heavy-duty handles and latches. The Renogy panel can be purchased with or without the solar controller and can be combined with a power station for the full off-grid package. The panel weighs just under 27 pounds. Courtesy of Amazon Weighing 28.66 pounds, the Go Power! GP-PSK- 130 is one of the heavier options out there, but it’s a great match for RVers who require a little extra off-grid power to top off batteries (or if an RV park bills for electricity separately). The 130-watt panel delivers an impressive 6.9 amps per hour, has a built-in solar controller with a digital screen to monitor input and transmit power, plus adapter cables to connect to a battery. The self-standing panels can easily fold in two and fit into the included case for easy storage—making them a great alternative to mounting to the roof. Courtesy of Home Depot If you’re interested in a solar panel for traveling but also require a battery charge station, Jackery Power Outdoors is a leader in off-grid power supplies. The Solar Generator SG550 comes with a whopping 100-watt panel that folds shut and can easily be toted away using the carry handle. The power station’s 500-watt continuous output can charge a laptop at least seven times before it requires a recharge. The panel also has a built-in MPPT module that monitors the voltage and output of the solar panel, adding up to 23% more efficiency, and can charge up to seven devices at one time. Courtesy of ebay Despite providing an impressive 160 watts of power, the Dokio Portable Monocrystalline Controller is a surprisingly affordable option for those shopping for panels on a budget. The folding panel is lightweight (just 9 pounds) and easy to carry but must be positioned in the sun by leaning it against a tent, car, or another sturdy surface (no kickstand is included). The panels can be connected directly to most power stations, but if you’re powering up a battery, alligator clips and a solar controller are included. Although water-resistant, the exterior is made of nylon and should not be left outside when not in use. Courtesy of EcoFlow When bringing a solar panel on camping trips, you’ll want to look for something lightweight, durable, and powerful enough to charge your cameras, portable speakers, lights, and other camping gadgets.

Types of Portable Solar Panels Monocrystalline: These are constructed from a single large silicon crystal. Monocrystalline panels are arguably the most effective because they’re able to produce a high amount of power even when sunlight is lacking. In terms of efficiency, monocrystalline solar panels are the best. While they’re the most expensive of the three types, they’re usually the most durable and least sensitive to high temperatures. Polycrystalline: The best solar panels for RVs, polycrystalline solar panels are created from multiple blocks of silicon. They take up much less space than amorphous panels and are less expensive than monocrystalline panels. They don’t produce as much power as monocrystalline panels, but they’re still a good investment for an RV. Amorphous: These panels are created by spreading silicon on a large bed. Also known as thin-film panels, they’re well-liked because they’re more budget-friendly than the first two while also being flexible and allowing for more installation options. On the negative side, they can take up around three times more space than polycrystalline and monocrystalline solar panels while still producing only as much power. 2. Efficiency The efficiency values are the amount of solar energy converted to DC electricity. They are usually shown in percentage form. A higher efficiency means the panel can weigh less and take up less space, but still have a solid output. Be sure you get a solar panel that maximizes its output while not taking up too much space. It’s important for the electrical output to supersede what you need to power your electronics. Also consider the climates you’ll be driving in. Efficiency is much more important if you’re not guaranteed to be in sunlight often. 3. Wattage Cells A higher wattage means the panel is better able to power several electronics simultaneously. Typically, a higher wattage means a better efficiency rating, but also a higher price point. Keep in mind you can always buy a lower wattage panel,…

Thanks to its impressive charging abilities and consistent performance across the board, this panel maintains its place at the top of the pack for another year. Though there may be other options out there that charge faster or look cooler, nothing beats this model when it comes to overall performance. When your electronics need a boost, this panel will deliver a consistent charge in variable conditions (from full sun to partially cloudy). In terms of features, we love the built-in ammeter and the zippered accessory pouch. We also appreciate this panel’s simplicity and reasonable price tag. With three USB ports and a classic fold-out design, the BigBlue is an excellent all-arounder that will efficiently charge most small gadgets. One downside to this panel is its weight. Weighing in at 23.5 ounces, it’s a bit heavy. As a result, it’s better suited for front-country use, though it will excel wherever you use it. Other than its weight, this panel receives high marks across the board.

It has a fast-charging speed: 3 hours and 40 minutes to charge a 6,000 mAh external battery in full sun, one of the faster in our review. It was also excellent at charging multiple devices at once, and it handled charge interruption as well as you could expect. It’s not the lightest model that we tested, but it does pretty well for its size (over 20 watts). Its tri-folding design is about the size of a magazine and is easy to store. This contender was hard to beat when it came to charging capabilities, weight, and price.

We love that it has a large capacity and can fully charge a phone multiple times when the battery is topped off. Additionally, the small solar panel works well enough for the battery to replenish using solar, even if it takes a few hours. In addition to all these great features, the Goertek rings in as one of the most reasonably priced options for solar charger set-ups. Our issues with this battery pack are similar to the problems we’ve had with other battery pack/solar options — patience is required. This product does not work that well as a solar charger alone; if you’re planning to fully charge the 25,000mAh…
