Charge the station from the sun
Add panels — we will work out how much sun a full charge takes and whether generation covers your daily use. Add panels — we will work out charging time and energy balance.
An estimate: panel yield for Kyiv is 4.5 hours of full sun a day in summer (with a margin) and 1 hour in winter, panel losses included; charging and inverter efficiency 85%; panels give no more than the solar input of the station accepts. Appliance hours are typical, the fridge counts only compressor time (~35%); half of the daily use is taken as night use, which the station has to cover. Real generation depends on cloud cover, the angle and how clean the panels are.
The EcoFlow 100W Flexible Solar Panel is a 100 W flexible solar panel that is mounted directly on the roof of a motorhome, van, boat or canopy. It weighs about 2.3 kg and bends up to 258 degrees, so it follows a curved roof where an ordinary framed panel will not fit. If you plan to buy EcoFlow 100W Flexible Solar Panel for a camper or a country house, note that this model is designed for permanent mounting rather than daily folding.
The panel works with all EcoFlow power stations and with most third-party 12 V systems. You can install one panel or connect several to reach the power you need.
Why the flexible 100W
70% lighter than a conventional panel
A conventional 100 W panel with glass and an aluminium frame weighs about 6 kg. The flexible EcoFlow panel weighs about 2.3 kg, which is 70% less. On the roof of a van or a boat this matters: less load on the mounts and less effect on the centre of gravity.
Bends up to 258 degrees
The panel follows the curve of the roof and does not stick out above it like a framed structure. It catches less wind on the road and needs no brackets. It is fixed with double-sided mounting tape, sealant adhesive or through the holes in its corners.
182 monocrystalline cells
Inside there are 182 monocrystalline silicon cells laminated with fibreglass. Conversion efficiency is 23%. The top of the panel is covered with a protective ETFE film.
IP68 protection
EcoFlow states an IP68 rating under IEC 60529: in laboratory conditions the panel withstands immersion at a depth of up to 1 m for up to 72 hours. On a roof this means peace of mind in heavy rain, snow and fog.
Connecting to a power station
The panel has a universal solar connector compatible with MC4. A Solar-XT60i cable is not included, so for an EcoFlow station you need a separate MC4 – XT60i cable, 2.5 m. If the station is far from the roof, add an MC4 extension cable, 3 m.
The open-circuit voltage of one panel is 20.3 V and the short-circuit current is 6.3 A. So one panel fits even stations with a narrow 11-30 V input:
- EcoFlow RIVER 2, RIVER 3 and RIVER 3 UPS – one panel on an input of up to 110 W.
- EcoFlow TRAIL 300 DC and TRAIL Plus 300 DC – XT60 input, 10-30 V.
- RIVER 3 Plus, RIVER 2 Pro and RIVER 2 Max – one panel or two in series.
- DELTA 2, DELTA 3, DELTA 3 1500 and DELTA 3 Max – one panel or two in series. Four panels are connected as two pairs in parallel: 40.6 V and 12.6 A, within the 11-60 V / 15 A input.
Two panels in series give up to 40.6 V open-circuit voltage. That is within the input range of DELTA, RIVER 3 Plus and RIVER 2 Pro, but more than RIVER 2, RIVER 3 and TRAIL accept. For those, several panels are connected in parallel through an MC4 branch connector, and the station still draws up to 110 W.
How much energy 100 W gives
The rating is measured in a laboratory at 1000 W/m² and +25 °C. In practice a roof panel delivers roughly 60-80% of its rating because it lies flat and heats up. On a clear summer day in Ukraine that is roughly 350-500 Wh per day; on a cloudy day it is several times less. You can work it out for your station and number of panels in the calculator above this description.
On a camper, two of these panels can cover lighting, a router and phone charging during the day, with the surplus going into the station for the night. A compressor fridge usually needs more, so check the balance in the calculator.
Who it is for
- Motorhome and van owners whose curved roof will not take a framed panel.
- Boats and yachts: the panel is light, does not mind moisture and needs no brackets.
- A canopy, gazebo or greenhouse at a country house, where a light structure must not be overloaded.
- A mobile office or coffee van where the station runs all day.
If you only need a panel from time to time and it is easier to lay it on the ground, look at the portable Lightweight series.

Installation tips
Before gluing, degrease the roof and check there are no sharp bumps under the panel. Leave a few millimetres between the panel and the roof where possible: it heats up less, and each degree of heating costs about 0.4% of power. Do not bend the panel further than 258 degrees and do not walk on it. Route the cables so that water runs away from the connectors, not towards them.
Frequently asked questions
Can I walk on the flexible panel?
No. The flexibility is for mounting on a curved surface, and the point load of a foot can damage the cells inside. On the roof, step around the panel or lay a temporary board over it.
Do I need a separate charge controller?
Not for EcoFlow stations: they have a built-in MPPT controller. For a third-party system with a 12 V battery you need an MPPT controller rated for the panel current.
How do I connect several panels?
In series if the station input accepts the combined voltage, or in parallel through an MC4 branch connector if the input is low-voltage. Before connecting, compare the combined open-circuit voltage with the input range of the station.
How is it different from a portable panel?
A portable panel is laid out on the ground and folded away every time. A flexible panel is mounted once on a roof or canopy and works whenever the sun shines, with no effort on your part.
The manufacturer warranty on the EcoFlow 100W Flexible Solar Panel is 36 months under the EcoFlow Europe policy, with service handled by EcoFlow in the EU. To buy EcoFlow 100W Flexible Solar Panel, place an order on the website: we ship by Nova Poshta across Ukraine, and you can pay on delivery.
