The best camping solar panels must meet a few requirements: portability, efficiency, and durability.
Portability comes first because when you’re camping — especially if you’re hiking or backpacking — you need a solar panel that can easily fit into your car and camping gear. If the panel is too large or heavy, then there is no use taking it with because it will consume too much space.
Efficiency is also important because the ultimate job of your solar panel is to turn solar energy into usable energy for your mobile devices. Panels that have a higher efficiency rating can do this more effectively, which is why this percentage matters.
Finally, durability is key because if you’re an avid camper, you are bound to encounter some bad weather. Your portable solar panel must be hardy enough to withstand high winds, rain, and even snow.
After evaluating each of these key components, it was clear that the FEELLE Power Bank was the winner. Not only can it fold up small enough to fit in your back pocket, but it’s waterproof and has the capability to charge several mobile phones at a time.
Because they can be used to recharge smartphones and emergency devices when you’re off the grid, flexible solar panels make your trip safer. Many of them have built-in LED flashlights for night use, and larger models can power small 110V appliances.
Diesel generators can also be used for this purpose, but they have several disadvantages: they’re noisy, they’re polluting, they can be dangerous and you must also carry their fuel.
On the other hand, solar panels are completely silent, which means they won’t disrupt the natural environment. They’re an energy-independent option that uses nothing but the power of the sun.
There are three major types of solar panels: thin-film, polycrystalline, and monocrystalline solar panels.
Monocrystalline solar panels have the highest efficiency ratings in the industry and can convert more than 20% of sunlight into usable electricity. Less efficient yet more affordable than monocrystalline, high-quality polycrystalline solar panels have an efficiency rating of around 17%.
Whereas mono and poly solar panels have a single silicon crystal and multiple silicon crystals per cell respectively, thin-film solar panels are not divided into cells. Instead, their entire surface is covered in layers of photovoltaic material. This allows for their enhanced flexibility and lightweight design.
Solar panels for camping can be classified into two main types:
The cost of solar panels for camping depends on many factors, especially wattage. For example, you may find pocket solar panels below 10W for less than $40, but you can expect to pay over $100 for a larger panel with an output over 30W. Features like durability and sunlight conversion efficiency also affect the price of portable solar panels.
Additionally, there are larger systems available, and prices increase accordingly. For instance, if you’re looking for a 1,500-watt power station with its own solar panels for recharging, the price can exceed $2,000. This may sound expensive, but it can be well worth it if you’re using RV solar panels for camping or need a reliable long-term setup.
Any solar expert will agree that purchasing the right product is key — this applies to both portable solar generators and fixed installations.
When comparing solar panels for camping, you should look for products that are durable and easy to use. Since you’re dealing with electricity, safety is also important — the risk of electric shock is higher when using low-quality solar panels.
The following are some other important factors you should consider before purchasing portable solar panels for camping:
If you choose the right wattage and battery capacity, you only need to carry one or two solar panels. For example, you can look for a compact and foldable 6W panel that fits in your pocket, and will produce enough power for your smartphone and an LED flashlight. On the other hand, a 50W panel produces enough electricity for several smartphones and small appliances.
We picked the FEELLE Portable Solar Power Bank as the Best Overall since it unfolds into a 6W panel that meets the most important needs — smartphone charging and lighting. You will need a larger system if you want to use small appliances. For example, you can use the Renogy PHOENIX 200W Power Station with a 50W solar panel to power most camp amenities.
Yes — portable solar panels are silent, safer, and easier to use than diesel generators. In addition, there is no need to carry diesel when using solar panels. When compared with standalone power banks, the advantage is that they can be recharged over and over again without a wall outlet.
Portable solar panels have a lifespan of between nine and twelve years. This is much shorter than fixed panels, which have an average lifespan of about twenty-five years. The lifespan of your panels depends on how often you camp, whether you stay on top of maintenance, and the weather conditions the panels are exposed to.
Solar panels for camping are designed to be user-friendly and can be set up without needing a professional electrician. The smallest foldable panels fit in your pocket or backpack, and you can simply unfold them and connect your smaller devices.
On the other hand, larger panels are normally connected to a portable power station, which includes adapters for many types of larger devices and appliances.
