How To Choose The Best Portable Solar Panel

Overall, the best portable solar panel for you would be fully capable of delivering your power needs – i.e., recharge your battery pack until it is fully equipped to recharge your devices. Whether you choose one solar panel or link several together for maximum energy, provided you get reliable solutions that best fit your need, it hardly matters. To ensure that you are delighted with your new renewable energy source, here are a few things to look out for when purchasing.

Type Of Solar Panel

When choosing a solar panel, you are likely to end up with one of three options – The CIGS, monocrystalline panel, or polycrystalline solar panels –

With the CIGS, you get a lightweight, flexible and cheaper option. However, it is often made of a few different materials, including plastic and fabric, which usually means that it is more prone to deterioration than panels made with one material alone. notwithstanding, this category of solar panels is often said to perform seamlessly in low light conditions

Alternatively, Monocrystalline panels are likely to handle deterioration more favorably. While  CIGS panels are significantly lighter and display more flexibility, monocrystalline panels are generally more efficient concerning performance than the CIGS – they are usually ideal for low power requirement users.

Finally, Polycrystalline panels are also relatively durable and efficient regarding power output. However, because of its many crystal ingots, which severely impact silicon purity, it ultimately leads to lower efficiency than monocrystalline solar panels.


Typically, your choice of how much power your portable solar panel can dispense depends on what you’re looking to power with your battery pack. Here is what you should know however; 2 Watts is sufficient power to handle iPods & cell phones – this is the barest minimum.

The recommended minimum for more significant devices such as laptops and cameras is 10 Watts, provided you can get up to 1-3 battery charges in one day.

30+ Watts will take care of everything from video equipment to powerful notebooks.

Ultimately, you can’t be tempted to buy a solar panel below your power requirements or too far above, affecting overall performance.

Battery Capacity

take note that your USB battery capacity should be at least 1-2x the daily power output of the USB solar panel charging it, and Universal battery packs for “12V” solar panels should have a capacity of at least 1-2x the daily production of the solar panel charging it


Look out for additional features such as water resistance. Weather resistance is an absolute must. Packability is also quite important. And since you’re looking to purchase portable solar panels, note overall weight. They should also have grommets, straps, loops, or handles to make them easy to attach to backpacks, panniers, tents, bikes, etc.
