Types of Portable Solar Panels 

Portable solar panels can be classified into three types based on the material used to make their cells, including monocrystalline, polycrystalline, and thin-film, whether you use them as camping solar panels or as everyday on-the-go device chargers.


Constructed with silicon wafers cut from a single silicon crystal, monocrystalline solar panels rank best in both energy production and efficiency. The purity of the solar cell increases the ability of the solar panel to absorb energy from the sun, allowing the monocrystalline solar panels to output a high amount of electrical energy.

This type of portable solar panel is easy to recognize because the solar cells are black and thicker than thin-film products. The silicon wafers are typically assembled into rows and columns to form a rectangle. These high-quality panels cost more than either polycrystalline or thin-film.


On polycrystalline panels, the solar cells are blue, not black, because the silicon wafers used to make the solar chargers and solar panels are composed of silicon crystal fragments that have been melted together and not made from a single silicon crystal. This manufacturing process reduces the price so they’re less expensive, but it also lowers the energy output. However, polycrystalline solar panels are still more efficient than thin-film solar panels.


Thin-film portable solar panels, which are made with a variety of materials, including cadmium telluride (CdTe), amorphous silicon (a-Si), and copper indium gallium selenide (CIGS), typically incorporate conducting layers made of glass, ethylene tetrafluoroethylene (ETFE), or aluminum or steel. Thin-film portable solar panels are the least efficient type of the three, but they’re generally more affordable than both polycrystalline and monocrystalline panels.

What to Consider When Choosing the Best Portable Solar Panel 

Whether you are looking for a portable solar panel for the RV or a smaller solar panel for a backpacking kit, learn about the various products’ features and specifications to make certain it’s the best portable solar panel for your purposes.

Size and Weight 

Size can actually refer to both the physical size and the size of the power output, but here, the focus is on the physical size and weight.

A solar panel’s size can be limited by its intended purpose. For instance, hiking with a 36-by-24-inch solar panel in the backpack might be difficult, but this size of solar panel is an excellent option for an RV. Choose a solar panel that’s large enough to gather the required energy, but small enough that it’s not a burden. A lightweight portable solar panel could weigh as little as 1 pound, while a heavy-duty portable solar panel can exceed 60 pounds.

Efficiency Rating

The efficiency rating is typically dictated by the type of portable solar panel.

  • Monocrystalline portable solar panels have the highest efficiency rating because they use a single piece of pure silicon crystal. Their efficiency ratings can exceed 20 percent.
  • Polycrystalline portable solar panels, with an efficiency rating ranging from 15 to 17 percent, are close to monocrystalline in efficiency, but they fall just short because of the impurities in the silicon wafers used to make the solar cells.
  • Thin-film portable solar panels vary in efficiency among products because they’re made with a variety of different materials. However, they typically have an energy efficiency rating of just 11 percent.

Higher efficiency is always better, but these products also cost more than low-efficiency solar panels.

Power Output 

Because of the differences in materials used to make the solar cells and the number of solar cells in a panel, power output also depends on the type of solar panel.

  • Monocrystalline portable solar panels are the best choice for power output. Some monocrystalline solar panels have power capacities that exceed 400 watts (W).
  • Polycrystalline portable solar panels and monocrystalline solar panels come in standardized sizes, including 60, 72, and 96 solar cell variants, and often hit a maximum of 200 watts.
  • Thin-film portable solar panels vary between products, but thin-cell solar panels rarely have power capacities of 100 watts or more.

Device Charging

Also determine goals for the charger; those who want to charge their devices directly should determine if a product has the outputs that allow for a direct connection. Many portable solar panels are designed to connect only to a battery. Other products connect with an RV battery or a car battery to provide power to the vehicle and its accessories.

While a boat or an RV may have built-in power outlets, when the engine isn’t running, the alternator isn’t recharging the battery. Connecting it to a portable solar panel can provide the power necessary to charge devices without draining the battery.

Battery Integration 

Adding a battery to a portable solar panel ensures stored energy is available even when the sun has gone down. However, only specific portable solar panels can connect to a battery. Some products are designed to connect directly to devices through USB ports, while other solar panels are made for charging vehicle batteries specifically.

To connect a portable solar panel to a vehicle battery, attach the positive wire from the solar panel to the positive battery terminal and attach the negative wire to the negative terminal—the same configuration used to connect a solar panel to a portable battery. However, a charge controller may be necessary to prevent the solar panel from overloading the battery and causing a reverse flow of energy from the battery to the solar panel.

How We Chose the Best Portable Solar Panels

Selecting the top portable solar panels currently available on the market was possible through extensive research into each product, including an inspection of the various product specifications, like power capacity, weight, panel type, and versatility.

Portable solar panels are used in a wide range of situations, whether users are sitting in the backyard at home or climbing up the side of a cliff, so it was necessary to identify products that could be used in a variety of circumstances without impacting the efficiency of the panel. If the weight was too high, then a user could carry the panel only for a short period of time, limiting portability. However, products that were too light needed to be mounted or otherwise secured to prevent them from blowing away.

The type of panel was another factor that was key to choosing top-of-the-line products. Monocrystalline solar panels were preferred over both polycrystalline and thin-film products due to the increased efficiency and power capacity. However, some polycrystalline and thin-film products were selected in order to provide a range of options.


Portable solar panels, solar chargers, and solar power banks are essential to enjoying an extended trip, but it can be difficult to choose a specific product. Take a look below for more information to help you decide on the best portable solar panel for your needs.

Q: Are portable solar panels effective? 

The best portable solar panels for RV trips are effective tools for generating electricity with little more than clear access to the sun.
