Best Portable Solar Panels – At a Glance

1. BigBlue 21W Portable Solar Panel – Best Overall

Specs:

• Power: 21 Watts (28 and 80 Watt versions also available)
• Number and type of port(s): 2 USB ports (5V/2.4A max each and 5V/3.8A max overall)
• Level waterproof: IPX4
• Dimensions: NC
• Weight: about 600 g

In terms of overall performance, very few panels can stand up to this model signed BigBlue, which comes in several versions (21 – 28 and 80 Watts). It is therefore quite natural that it ranks as the first step of our selection.

BigBlue 21W Portable Solar Panel features an optimized foldable design to lend itself to use on the go, camping, or during outdoor activities (hiking, climbing….). It includes four sturdy eyelets, four carabiners, and a zipped pocket to put your phone. A hook is also provided for attaching to a backpack.

When folded, this panel reveals its sleek and practical design. However, many will find it bulky and heavy at a weight of around 600 g. It has an IPX4 level of waterproofing. This means you can use it in the rain or a humid fog. However, USB ports must remain out of the reach of water.

BigBlue 21W Portable Solar Panel is our special recommendation for outings because it offers the most consistent and efficient portable power source we’ve reviewed. Composed of panels made from monocrystalline, the BigBlue 21W provides a constant charge for most small gadgets, and in many situations.

Whether the weather is partly cloudy or the scattering of sunlight, you can choose this device to keep your electronic devices active. This compact solar panel is also CE, FCC, and RoHS certified, and includes overheating, overloading, and short circuit protection.

It is compatible with almost any 5V Android or IOS gadget. This device is equipped with two USB ports (5V/2.4A max each and 5V/3.8A max overall), allowing two devices to be charged simultaneously. Although there are other options that charge faster or are more durable, the BigBlue 21W is appreciated for its reasonable price, ease of use, and reliability.

Best Portable Solar Panels: Selection Criteria

To find the right portable solar panel for your needs, follow our buying guide.

Type of Portable Solar Panel

There are several types of portable solar panels available on the market, each with its own advantages and applications. Some common types include:

• Foldable Solar Panels: These panels are designed to fold into a compact size, making them easy to carry and transport. They often come with built-in handles or carrying cases for added convenience.
• Rollable Solar Panels: Unlike rigid panels, rollable solar panels are flexible and can be rolled up like a mat. They are lightweight and easy to store, making them suitable for backpacking, camping, and other outdoor activities.
• Briefcase Solar Panels: These panels are designed to resemble a briefcase when folded, with handles for easy carrying. They are often used for charging small electronic devices or providing power in remote locations.
• Backpack Solar Panels: These panels are integrated into backpacks or attached as accessories, allowing users to charge their devices while on the move. They are popular among hikers, travelers, and outdoor enthusiasts.
• Solar Chargers: These compact panels are designed to directly charge devices like smartphones, tablets, and power banks. They typically come with USB ports for easy connectivity.

Power Output (Wattage)

Consider the power output of the solar panel, usually measured in watts (W). Determine your power needs based on the devices you plan to charge or power using the solar panel. Higher wattage panels can charge devices faster and handle more power-intensive devices.

Size and Portability

Evaluate the physical dimensions and weight of the solar panel. A balance between size/portability and power output is essential, especially if you plan to carry the panel during outdoor activities or travel.

Type of Solar Cells

Different types of solar cells, such as monocrystalline, polycrystalline, and thin-film, have varying efficiencies and performance characteristics. Monocrystalline panels are more efficient and compact but may be more expensive.

Durability and Build Quality

Look for portable solar panels made from durable materials that can withstand outdoor conditions like moisture, UV exposure, and impact. Quality construction ensures longevity and reliable performance over time.

Output Connectivity

Check the output connectors and compatibility with your devices. USB ports are common for charging smartphones and small electronics, while DC outputs may be needed for larger devices or battery banks.

Integrated Features

Some portable solar panels come with integrated features like built-in battery packs, charge controllers, LED indicators, and protective cases. Assess these additional features based on your requirements.

Frequently Asked Questions

Q1. How long will it take to charge a smartphone?

The speed of recharging a smartphone via a solar panel will depend on the power of the solar panel, sunshine, and your smartphone. For example, it is considered that a 15W solar panel will take between 1h30 and 2h to charge a smartphone in direct sunlight, compared to 3 to 5h in overcast weather.

Q2. How much power can I expect from a portable solar panel?

The power output of a portable solar panel is measured in watts. Outputs can range from around 5W for small, ultra-portable panels to over 100W for larger, more powerful models. Your choice should depend on the devices you plan to charge and how much energy they require.

Q3. What type of device can I charge with a portable solar panel?

Depending on the type of solar panel, you can recharge both small electronic devices (such as headlamps for example) and slightly larger devices such as walkie-talkies, GPS, smartphones or devices. More powerful solar panels will allow you to charge computers (provided they have a DC outlet) or more power-hungry devices. All this information will be placed in the context of your use.

Q4. I hesitate between a solar panel and a hybrid solar panel with battery, which is the best choice?

Everything will depend on your needs and your uses. A conventional solar panel will charge your devices faster. But the charge will not be constant. On the other hand, a solar panel with battery will be able to keep the charge accumulated during the exposure phases even in cloudy weather or after dark.

Some models will even be charged via a conventional electrical outlet. On the other hand, the batteries will see their charge capacity decrease (like any device equipped with a battery).

Q5. Are there essential or practical accessories to facilitate the use of a solar panel?

Depending on your use, you can find a multitude of accessories that can facilitate your use of a solar panel. We note among others: the presence of eyelets to hang the solar panel on a backpack or a tree, a pocket for folding models that will allow you to shelter your smartphone while it is charging by using the solar panel, and the presence of a detachable battery for hybrid models or even different types of interchangeable connectors.

Q6. I would like to bring a portable solar panel for outdoor water activities, is this possible?

Absolutely! Portable solar panels are a fantastic choice for outdoor water activities. They provide a convenient and eco-friendly way to power various devices and equipment you might use during these activities. Just make sure to choose a waterproof model!
