EcoFlow 100W Flexible Solar Panel
Ultra-light at 5.1 pounds and flexible up to 258 degrees, it hugs the roof of a van, a boat, or an RV: a discreet solar panel that disappears once mounted.
Characteristics
- Power: 100W, flexible panel
- Weight: 5.1 lbs (ultra-light)
- Flexibility: Curves up to 258 degrees
- Durability: IP68 rating, universal compatibility
- Flexible 258 degrees, 5.1 lbs, hugs curved surfaces
Detailed overview: EcoFlow 100W flexible solar panel for van and boat
The EcoFlow 100W flexible solar panel covers a need that rigid panels cannot: permanent solar mounting on curved or lightweight surfaces. Where a framed panel stays flat and heavy, this flexible model bends up to 258 degrees, hugging the domed roof of a van, an RV, a boat, a trailer, or a cabin.
Its biggest advantage is weight: at just 5.1 pounds, it is a fraction of the weight of a rigid panel with similar output. That opens up mounting spots that would not handle a heavier load without extra reinforcement. Thin and low-profile, it sits close to the surface for a clean, aerodynamic finish.
On durability, it carries an IP68 rating, strong protection against water and dust that suits it for permanent outdoor exposure through all seasons. Its universal compatibility means it works with most solar setups, whether wired through an EcoFlow charge controller or a third-party one, using standard MC4 connectors.
Light, flexible, and rugged, the EcoFlow 100W flexible solar panel is built for anyone fitting out a van, an RV, a boat, or a cabin who wants to add solar capacity without piling on weight or drilling more holes than necessary.

☀ How fast does this panel recharge a power station?
The EcoFlow 100W Flexible panel (100 W) recharges une Jackery Explorer 1000 v2 (1070 Wh) in ~15h or une EcoFlow Delta 2 Max (2048 Wh) in ~29h, in full sun.
| Compact / mid | Recharge |
|---|---|
| Jackery Explorer 100 Plus (99 Wh) | ~1h25 |
| EcoFlow River 2 (256 Wh) | ~3h40 |
| EcoFlow River 2 Max (512 Wh) | ~7h20 |
| EcoFlow River 2 Pro (768 Wh) | ~11h |
| High capacity | Recharge |
|---|---|
| EcoFlow Delta 2 Max (2048 Wh) | ~29h |
| Allpowers R3500 V2 (2880 Wh) | ~41h |
| Jackery Explorer 3000 v2 (3072 Wh) | ~44h |
| EcoFlow Delta Pro 3 (4096 Wh) | ~59h |
Estimate in full sun (ideal conditions). In practice, count on 3 to 5 hours of truly useful sunlight per day, so a full recharge may span several days depending on weather and orientation.

Comparison
Around $150 to $250, the EcoFlow 100W flexible solar panel competes with the field of 100W flexible panels, the kind shoppers land on searching for a "flexible solar panel" or a "van flexible solar panel." Here is how it stacks up against three references: the Renogy 100W Flexible, a generic flexible panel, and a classic rigid 100W panel.
| Criterion | EcoFlow flexible 100W | Renogy 100W Flexible | Generic flexible 100W | Classic rigid 100W |
|---|---|---|---|---|
| Power | 100W | 100W | 100W | 100W |
| Type | Flexible (258 deg) | Flexible (248 deg) | Flexible | Rigid |
| Weight | 5.1 lbs | 6.2 lbs | ≈ 5.5 lbs | ≈ 15 lbs |
| Rating | IP68 | IP67 | IP65 | IP65 |
| Observed price | ≈ $199 | ≈ $210 | ≈ $170 | ≈ $130 |
In short, the EcoFlow 100W flexible panel stands out for its strong curve (up to 258 degrees), its low weight, and its top-tier IP68 rating, well suited to a permanent mount on a curved surface. A classic rigid panel costs less but is far heavier and cannot bend at all, while the Renogy and generic options offer similar specs at a comparable price. For fitting out a van, boat, or cabin without adding weight, the EcoFlow flexible 100W is a strong choice.

Our tester's review: Julien De Jurquet
This 100W flexible panel earns its keep doing what a rigid panel simply cannot: mounting permanently on a curved roof. On a domed van roof, it laid flat with almost no effort thanks to that 258 degree flex, and once secured, you genuinely forget it is there, no wind noise, no snagging on low branches, no dent in the vehicle's lines. At 5.1 pounds, it is light enough to mount on structures that would not take a framed rigid panel without reinforcing something. In daily use, 100W is enough to keep a leisure battery topped off or give a steady daytime boost, exactly what you want so the battery never runs flat mid-trip. The IP68 rating is reassuring for something that lives outside year-round. Two honest notes: like any flexible panel, it needs airflow underneath, laid flat on a dark surface it runs hot and loses some output, and it has no kickstand, this is a permanent mount, not a portable panel you fold out. For fitting out a van, a boat, or a cabin without adding weight or drilling more than necessary, it does exactly what it promises.

Thanks to its 258 degree flex, it hugs most curved or flat surfaces: van, RV, boat, trailer, or cabin roofs. It is built for a permanent mount, not to be unfolded like a portable panel.
It weighs just 5.1 pounds, against roughly 15 pounds for a framed rigid panel, and it bends to follow the shape of the surface. Ideal for lightweight or curved structures where a rigid panel would not fit.
Yes. Its IP68 rating gives strong protection against water and dust, so it is built for permanent outdoor exposure, rain included.
Yes, it offers universal compatibility and fits most solar setups through standard MC4 connectors, whether paired with an EcoFlow charge controller or a different brand.
