The best portable solar panel for overlanding is the one that refills your power station faster than your fridge empties it. A 12V fridge can draw 360 to 600 Wh a day, and a panel only gives you that on a good day. The right size depends on sun, season and what you plug in.
This is a researched buying guide built from manufacturer spec pages for Jackery, EcoFlow and Bluetti. We compare three folding panels from 200W to 350W on weight, price per watt, voltage and connector, and the daily watt-hours you can plan on. Pair it with our power station guide so the panel and battery match.
Our pick: Jackery SolarSaga 200W, 14.33 lbs, about $380, IP68 and a 3+2 year warranty. Lightest per watt: EcoFlow NextGen 220W Bifacial, 15.4 lbs and a listed $399, though EcoFlow's own store showed it sold out. For big batteries: Bluetti PV350, 350W and 30.6 lbs, with MC4 connectors. Plan on about 750 Wh a day from the 200W in good sun, which covers one hot fridge day or two mild ones.
Jackery SolarSaga 200W
Jackery lists the SolarSaga 200W at 14.33 lbs, which is about 14 watts per pound. It carries an IP68 rating, a 3+2 year warranty and a roughly 25% conversion rate, and Jackery's own page shows about $379. In good sun it gives you about 750 Wh a day by our math, enough for one hot fridge day at 600 Wh or two mild ones at 360 Wh. It folds to about 23.6" x 23.5" x 1.6" so it stores flat behind a seat.

This table puts the specs side by side. The last two columns are our own calculation, so you can see what you pay per watt and carry per watt.
| Panel | Watts | Weight | Price | Price per watt | Watts per lb |
|---|---|---|---|---|---|
| Jackery SolarSaga 200W | 200 | 14.33 lbs | about $380 | $1.90 | 14.0 |
| EcoFlow NextGen 220W | 220 | 15.4 lbs | about $400 | $1.82 | 14.3 |
| Bluetti PV350 | 350 | 30.6 lbs | about $750 | $2.14 | 11.4 |
Formula: price / watts, and watts / weight in lbs, using the front-face rating. Prices are rounded from maker sites in October 2026.
The Jackery and EcoFlow are close on both measures, and the EcoFlow's rear face adds output only when light reaches the back. The Bluetti is heavier for its output and costs the most per watt, but it is the only one here with enough watts to fill a big battery in a day.
How Much Power You Actually Get Per Day
The watts on the box are lab numbers. A panel makes its rated watts only under bright sun, pointed at it. To plan, use peak sun hours (PSH), the equivalent hours of full-strength sun, and a loss factor for heat, cables and angle. We assume 75% of rated output, our own planning figure, the same one we use in the power station guide.
| Panel | Wh/day at 3 PSH | Wh/day at 5 PSH | Mild fridge days at 5 PSH (360 Wh) |
|---|---|---|---|
| Jackery 200W | 450 | 750 | 2.1 |
| EcoFlow 220W | 495 | 825 | 2.3 |
| Bluetti 350W | 788 | 1,313 | 3.6 |
Formula: watts x PSH x 0.75. Fridge days = Wh at 5 PSH / 360 Wh, using a 30 Ah/day (360 Wh) planning figure; a hot day at 600 Wh cuts it to about 60 percent of that.
Sun varies by season and place. The Department of Energy notes that Denver receives nearly three times more solar energy in June than in December. So 3 PSH is a fair winter or Pacific Northwest figure, and 5 PSH suits a clear desert summer day. Check your fridge's own spec sheet for its real draw.
Matching a Panel to Your Station
Three numbers decide the match. First, the panel's watts must not exceed your station's maximum solar input. Second, the panel's open-circuit voltage (Voc) must stay under the station's maximum input voltage. Third, the connector must match, or you need an adapter cable.
The Jackery lists a 22V Voc, the EcoFlow 21.5V and the Bluetti 46.5V. The Bluetti's figure is more than double the others, which is why a panel built for one brand of station is not always a drop-in for another. The Jackery uses a DC8020 port, the EcoFlow ships an XT60i cable, and the Bluetti uses MC4 connectors per retailer listings. Read the solar input line on your station's spec sheet before you buy, then match watts, volts and plug.
Two panels wired in series add their voltages, and two wired in parallel add their current. A pair of 22V panels in series gives about 44V, which can exceed a small station's limit, so follow your station's manual rather than guessing.
Roof Load, Carrying and Setup
These panels fold flat to 1 to 2.5 inches thick. Store them inside, not on the roof. The Jackery at 14.33 lbs is easy to carry. The Bluetti at 30.6 lbs is a two-hand job. If you do carry a panel on the roof, count it against your dynamic load alongside the tent and crossbars; a 125-lb tent plus 20-lb bars plus a 14-lb panel is 159 lbs.
Park so the panel sits in sun while the vehicle shades the fridge side. Tilt toward the sun, move it every few hours, and keep the cable out of the walkway. Keep the connectors dry and clean, and unfold the panel on a stable surface so wind cannot flip it onto your paint or a neighbor's tent. Solar is the quiet alternative to a generator. Never run a generator or fuel heater inside a tent or vehicle, because of carbon monoxide.
Check the cable length too. Jackery lists a 3 m (about 10 ft) cable, so you can park the vehicle in shade and set the panel in the sun beside it.
Who Should NOT Buy a Portable Panel Yet
Skip it if you drive every day. A vehicle alternator charging a dual-battery system with a DC-DC charger refills a fridge battery for free while you move. Skip it if you camp one night at a time, because the station's wall charge before you leave is cheaper. And skip it if you have not picked a power station, since the station sets the watts, volts and plug. Read the 12V fridge guide first, then the power station, then the panel. Our rooftop tent guide covers the roof budget.
One more case: if your station tops out at 100W or 200W of solar input, a 350W panel does not charge faster, it just costs more and weighs more. Buy to the station's input limit, not to the biggest number on the shelf. If you cannot find that limit in the manual, ask the station maker before you order, and keep the panel's return window open until you have seen it charge at the expected rate.
A 3-Day Trip Worked Example
Say your fridge runs 360 Wh a day in mild weather and your station holds 1,000 Wh. Over three days the fridge uses about 1,080 Wh, which is more than the battery holds. With no panel, you run dry on day three.
- Jackery 200W at 5 PSH: 750 Wh a day in, 360 Wh out, so the battery gains about 390 Wh a day and ends the trip full.
- Same panel at 3 PSH: 450 Wh a day in, so the battery still gains about 90 Wh a day.
- Hot weather at 600 Wh a day and 3 PSH: 450 Wh in against 600 Wh out loses 150 Wh a day, so the 1,000 Wh battery lasts about six days instead of one and two-thirds.
The lesson is that a 200W panel is enough for a mild three-day trip but thin for hot weather under clouds. Add the second panel, or move to a 350W panel, only if you camp more than three nights in one spot or your fridge is a large model.
How We Chose
This is a researched buying guide, not a field test. We started with panels sold on Amazon and kept those whose maker publishes watts, weight and price: Jackery, EcoFlow and Bluetti. We dropped the EcoFlow 400W because its US page lists no weight and retailers describe two different 400W models with different weights, the Jackery SolarSaga 400W because we could not find its current specs, and the Anker SOLIX PS100 because Anker's store was sold out with conflicting weights and prices and we could not confirm an Amazon listing. We ranked on watts, weight, price per watt, warranty and IP rating, then checked efficiency claims against each maker's page.
Prices are rounded from what we saw in October 2026 and change with sales, and Amazon prices can differ from maker prices. Efficiency figures are the makers' claims, not ours. The Bluetti connector type comes from retailer listings, not the maker page we could open.
Frequently asked questions
How many watts of solar do I need for a 12V fridge?
Start from your fridge's daily Wh, often 360 to 600 Wh on our planning figures. A 200W panel makes about 750 Wh on a 5-PSH day at 75% efficiency, so it covers one hot fridge day or two mild ones. Add a second panel or choose 350W if you want margin for clouds.
Can I plug any solar panel into any power station?
No. Match the panel's watts to the station's maximum solar input, keep the panel's open-circuit voltage under the station's input limit, and use the right connector or adapter. Jackery lists a DC8020 port, EcoFlow ships an XT60i cable, and Bluetti's PV350 uses MC4 connectors.
Is a 350W panel too big for a weekend trip?
Often yes. The Bluetti PV350 weighs 30.6 lbs and is 35.6 inches wide folded, and your station may cap solar input below 350W or below its 46.5V open-circuit voltage. For 1-3 nights, a 200W panel gives more than one fridge day at 5 PSH.
Do solar panels work in winter or on cloudy days?
Yes, but less. The Department of Energy notes that Denver receives nearly three times more solar energy in June than in December. Plan on about 3 PSH, or 450 Wh from a 200W panel, and carry a larger battery.
Should I mount a portable panel on my roof?
Fold it and store it inside. A roof-mounted panel counts against your dynamic roof load with the tent and crossbars, and your manual's number is the limit. Set the panel on the ground in the sun at camp.
