The Best Portable/Foldable Solar Panels


Purpose
Ideal for occasional solar users, portable (foldable) solar panels can be stored in a compact space and can be deployed only when needed. Whether you’re keeping one in your car for emergencies, using it for backup power during outages (though useless at night), or taking it camping, these panels provide a versatile and convenient power solution.

Not Weatherproof – Use Only on Sunny Days
Unlike permanent flat-panel solar systems, which are designed to be fully weatherproof, most portable solar panels are only water-resistant at best. In many models, the controller box must stay dry, so avoid exposure to rain, snow, or excessive moisture.

Everything Included (Except Battery for Power Storage)
A typical solar panel setup requires multiple components, including a charge controller, cables, and connectors. However, portable solar panels come with all of these built-in (except the cables). To use:
1️⃣ Unfold the panel and place it in direct sunlight
2️⃣ Connect your USB or DC device for direct charging
These panels do not include batteries for power storage. If you want to store solar energy for later use, you’ll need a USB Power Bank (for USB ports) or a Portable Solar Power Station (for DC ports) (Reviewed here).
Due to their lightweight and foldable design, these panels cost about 30%–60% more per watt than fixed panels—but their portability opens up a whole new range of uses.
