Types of Portable Solar Panels
This solar panel type uses structured pieces of silicon to craft a catch for the sun’s rays. Usually, the cells are brought together in lines on the panel. This type of panel has the most complex structure. Typically, this design is capable of generating a lot more power due to increased efficiency. It tends to be heavier and more difficult to fold. As a result, even the portable options are a lot bulkier.
Perhaps the most common material in portable solar panels, the thin structure type is made out of blended materials. Usually it is a mix of elements, each lending a different benefit when capturing rays. Common materials include silicon, gallium, copper, indium, and selenide. By incorporating a different range of ingredients in different concentrations, the panel becomes more or less efficient. It also means there is more wiggle-room in terms of weight.
Earning its title by cutting a silicon crystal instead of using fragmented cells as in the polycrystalline counterpart, this type of solar panel is fairly common. Though they usually run a higher price tag, the structure can take in a lot of the sun’s rays. It is very energy efficient, thanks to the focused lines in the design. The panels come with a film over the top of the silicon parts since they need to be protected.

Portable Solar Panel Pricing
- Under $100: Portable solar panels in this price range use a trickle charge and are usually very small. Folding compactly, they work only for minimum energy requirements.
- Between $100 and $300: Most portable solar panels fall within this price range. You can find options of all sizes and all three types. Depending on efficiency, the price varies within this spectrum.
- $300 and up: High-end solar panels almost exclusively use poly or monocrystalline structures. A bit bulkier, these are suitable for extreme energy demands and longer outdoor trips.
The panel itself is probably the most essential feature. It is the component that uses raw elemental traits to convert the sun’s rays into electric energy. The type of construct largely dictates the quality and type of the panel. Most portable panels use a thin-film design, letting it bend and stay lightweight. Look at the surface area and overall structural integrity when investigating this feature.
Solar panels inherently take up a lot of space. The larger the surface area, the more rays can be absorbed. When it comes to portable selections, however, there is a balance between mobility and efficiency. Most portable options fold down, meaning they are less likely to use a crystalline structure. The thin-film is less vulnerable to bending and lets you tow it more easily.
Whether the unit folds onto itself or comes with a backrest, there needs to be a way to prop it in the sunlight without risking damage. Instead of leaning it flat on the ground, even a small level of elevation can improve access to rays. Take a look at the style of the stand and if it's easy enough to adjust. This will ensure that you don't have struggles with accessing the raw energy source and preventing impact damage.
Though it is less common on portable options, many solar panels include a power bank. It holds onto the charge in battery form until you are ready to use it. This adds a lot of value since you no longer require full sun exposure and a trickle charge. Usually, if the portable option has a power bank, it will be very small.
Finally, you need to be able to extract the power from the panel. There needs to be a viable outlet to use electrical energy. Most options rely on USB connections, though there are some which are compatible with car adapters. It is less common to see portable adapters with AC outlets since users would usually just use the electrical grid. However, it isn’t unheard of and can be useful in survival scenarios.
- Size: When you make your pick, keep in mind the size you are willing to deal with. A huge factor in portability is the sheer size and structure. Check the dimensions on the solar panel to be sure that it will fit with your regular gear. Also, consider how much room it will take up when expanded and in use. This will determine how much utility you can get from it.
- Weight: Another way to measure portability is to consider how heavy the solar panel is. Think about whether you need a solar panel for an RV or boat or will be trucking it around in a backpack. Consider how heavy an item you are willing to bring with you when you go to make your choice.
- Maintenance: Next, take a look at the upkeep needs for the solar panel. All of them need to be wiped down, avoid scratches, and be stored somewhere safe. Naturally, the larger the panel, the more work and care are required. While maintenance needs are fairly limited, consider how much time you can afford to spend on the task.
- Supply: It may seem obvious, but take a look at the power demand of the devices you plan to charge. Try to work with real numbers in terms of wattage and amperage. The wattage speaks directly to the amount of power you get. In most situations, it takes a large surface area to get up to 100 watts.
- Time Investment: Finally, think about the transfer rate between the solar panel and the technology you’re charging. For this, you want to direct your attention to the amperage. It speaks to the electron flow rate during charging. Lower amperage means you will spend more time waiting to get the charge you seek.

- Keep your solar panel in direct sunlight. While ambient rays may cause a small-scale effect, the real results come from the brightest beams. If possible, use it as close to high noon as you can.
- Clear out the outlets with pressurized air to prevent dust from occurring. Be careful when plugging in your devices to avoid issues with the circuitry and connection.
- Position it properly relative to the sun’s place in the sky. These panels work best when receiving the most access to sunlight. Use the stand and angle it correctly.
- Prevent scratches to the panel and the protective layer. These scratches impede the energy efficiency of the overall system and often can’t be repaired.
- Don’t let dust build up on the panel. Wipe it down after using it, or if you see it get too dusty. It might seem like a small layer, but it directly impacts the sunlight’s uptake.
- Try to charge only one device at once. While most panels have multiple outlets, it draws power from the same source. To dedicate more amperage to your device, make it the only one charging.
- Unplug your device once it’s done charging. Though most modern versions have a chip to prevent overcharging, it is best to play it safe and take out your device once it’s ready.
- Check the compatibility beforehand to ensure that you can use your chosen devices with that solar panel. In most cases, you can get an adapter if there isn’t a good fit.
