We did not test these panels. Specs below come from each Amazon listing.

1. Best Overall for Backpacking: BigBlue 28W Solar Panel Charger

BigBlue 28W High-Efficiency Solar Panel Charger

• Weight and size: 1.5 lb; folds to 11 x 6 x 1.4 in
• Ports: 2 USB-C and 1 USB-A, 5V/3A each, 5V/4.8A combined
• Weather: IP44 panel (the USB junction box is not waterproof)
• Included: USB-C to USB-C cable, carabiners

Check Price on Amazon

Why it made the list: At 1.5 lb, this is the lightest pick, and it has by far the biggest rating pool, thousands of ratings with a solid average. BigBlue says its N-type cells help in low light. Two USB-C ports let you charge a phone and a power bank at once.

Highlights:

• Lightest panel of the three
• Top rated portable solar panel for backpacking by volume
• Carabiners for hanging on a pack

Trade-off:

• USB only; the maker says it cannot charge laptops or large power stations.

Best for: Backpackers who want to keep a phone, GPS and headlamp charged on long trips.

2. Best Budget (Under $100): FlexSolar 40W Foldable Solar Panel

FlexSolar 40W Foldable Solar Panel Charger, USB-C, USB-A and DC Outputs

• Weight and size: 1.76 lb; folds to about 8 x 11.1 x 1.8 in
• Ports: PD USB-C and QC3.0 USB-A (18W max each), 19V DC output (40W max)
• Weather: IP67 panel with ETFE coating (junction box is not fully waterproof)
• Efficiency: 24% monocrystalline cells (maker claim)

Check Price on Amazon

Why it made the list: The FlexSolar costs less than our top pick and adds a DC output for small power stations, which the BigBlue lacks. It is well rated by buyers, with over a thousand ratings. The maker notes that shade or a poor angle can cut output by up to 70%, so aim it at the sun around 45 degrees.

Highlights:

• Lowest price of the three
• USB-C, USB-A and DC outputs
• IP67 rated panel and two carabiners included

Trade-off:

• At 1.76 lb it is a little heavier than the BigBlue, and the junction box should stay out of heavy rain.

Best for: Hikers who base-camp or carry a small power station and want a cheap, good portable solar panel for backpacking.

3. Best Premium / Upgrade Pick: Goal Zero Nomad 20

Goal Zero Nomad 20, Foldable Monocrystalline 20W Solar Panel

• Weight and size: 2.25 lb; folds to 11.5 x 7.4 x 1.25 in
• Output: built-in 8mm cable plus USB port; 18 to 22V
• Setup: 180° adjustable kickstand; hangs on a backpack
• Warranty: 1 year, US-based support

Check Price on Amazon

Why it made the list: Goal Zero builds a full ecosystem of power banks and stations, and the Nomad 20 plugs straight into them with its 8mm cable. It is highly rated by buyers, with hundreds of ratings. It is heavier and lower in watts than the BigBlue, so it earns the premium slot for its ecosystem, kickstand and support, not raw output.

Highlights:

• Direct 8mm link to Goal Zero power banks
• Adjustable kickstand for better sun angle
• Brand with US-based support

Trade-off:

• 20 watts is less than our other picks for more money.

Best for: Backpackers who already own Goal Zero gear.

We did not test these panels. We compared Amazon listings for small folding panels on stated weight, folded size, output ports, weather rating and included extras, then looked at star averages and rating counts. We left out 100W-plus car camping panels as too heavy.

Size & form factor

• 100w: Great for car camping but usually several pounds; too heavy for most packs.
• 200w: Built for power stations; see our best 200w portable solar panel guide.
• 400w: RV and base-camp territory only.
• 60w: The upper limit for a strong pack; better for base camps.
• Small: 10 to 30W panels are the sweet spot for backpacking.
• Large: More watts, more weight; save these for vehicles.

Type

• Foldable: The standard; the best foldable solar panel for backpacking packs flat.
• Portable: Check the actual weight.
• Monocrystalline: The most common cell type in efficient small panels.
• Flexible: Thin sheets that bend; lighter, but check durability.
• Bifacial: Collects light from both sides; mainly larger panels.
• Waterproof: Look for an IP rating and check whether the ports are covered.
• Suitcase: Rigid panels for vehicles, not for trails.

Features worth paying for

• Kickstand: Helps you angle the panel at camp.
• Mc4 cables: Used on big panels for power stations; not needed for USB charging.
• Usb ports: USB-C is the most useful for modern phones and power banks.
• Charge controller: Built-in chips on USB panels regulate output; big panels rely on the power station.

Weight vs comfort: car camping or backpacking

For car camping, weight hardly matters, and our best portable solar panel for camping guide covers bigger panels. On foot, every ounce counts, so a 1.5 to 2.5 lb panel is the realistic range.

Weather & season ratings

A water-resistant panel survives light rain, but keep ports dry. In winter, short days and low sun cut output a lot, so carry a bigger power bank.

Setup, packing & storage

Strap it to your pack on open trails; at camp, face it at the sun and move it as shadows shift. Store it flat and dry.

Materials, repairs & warranty

Fabric-covered panels resist scratches; keep the cell surface clean. Check the warranty; Goal Zero lists 1 year on the Nomad 20.

How much should you spend?

• Under $100: Small folding panels like the BigBlue and FlexSolar.
• Under $200: Branded panels like the Goal Zero Nomad 20, or 100W folders for car camping.
• Under $300: 200W panels for power stations.
• Under $500: Large premium panels for vehicles or an RV; see our best portable solar panel for rv guide.

Weight and output ports matter most. A panel you leave at home because it is heavy helps no one, so start with the lightest model that charges your devices.

How long does a portable solar panel last?
