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 220W Lightweight Solar Panel is a new-generation 220 W bifacial portable panel. EcoFlow makes it 46% lighter than its previous 220 W bifacial model: folded, it measures 603 x 598 x 36 mm and is carried by its handle. If you want to buy EcoFlow 220W Lightweight Solar Panel for a RIVER 3 Plus or a DELTA, it is the most powerful panel in the series that one person can still carry comfortably.
The XT60 cable is built in, and the stand is integrated into the housing and adjusts from 30 to 60 degrees.
Why the 220W Lightweight
Lighter and more compact
Unfolded, the panel measures 2270 x 598 x 26 mm; folded, 603 x 598 x 36 mm. According to EcoFlow’s specifications it weighs 5.1 kg (±0.3 kg). It fits in the boot next to the station and needs no separate kickstand case.
Bifacial generation: up to 243 W
Under standard conditions the front side delivers 220 W. Using the BNPI method, which counts light on the rear side, EcoFlow states 243 W. Over a light surface, grass, sand or snow the rear adds energy to the rating.
N-Type TOPCon and 25% efficiency
The monocrystalline N-Type TOPCon cells convert up to 25% of light and lose less power in the heat. On a Ukrainian summer day this shows most in the hours when the panel is hottest.
30-60° stand and angle guide
The built-in stand adjusts from 30 to 60 degrees, and the solar angle guide on the housing shows when the panel is aimed straight at the sun. This makes it easier to turn the panel during the day.
IP68 protection
The panel is protected against water and dust to IP68, so rain and dew do not harm it. EcoFlow does not recommend leaving Lightweight portable panels hanging outdoors for long periods or mounting them on a vehicle.
Compatible power stations
Open-circuit voltage is 21.4 V and short-circuit current is 12.2 A under standard conditions. Compatibility:
- RIVER 3 Plus, RIVER 3 Plus Wireless, RIVER 3 Max Plus, RIVER 3 Max, RIVER 2 Pro and RIVER 2 Max – input up to 220 W, which the panel fills completely. A RIVER 3 Plus charges from 0 to 100% on it in about 1.5 hours.
- DELTA 2, DELTA 3, DELTA 3 1500, DELTA 3 Plus, DELTA 3 Max and DELTA 3 Max Plus – one panel directly. Two panels in series give 42.8 V within the 11-60 V input, 440 W in total; this needs XT60 – MC4 adapters.
- DELTA Pro and DELTA Pro 3 – several panels in series within the high-voltage input.
- RIVER 2, RIVER 3, RIVER 3 UPS and TRAIL – the voltage fits, but these stations draw up to 110 W from solar. The 110W Lightweight is enough for them.
How much energy 220 W gives
In practice a portable panel delivers roughly 60-80% of its rating. On a clear summer day in Ukraine that is roughly 750-1100 Wh per day. That is enough to fill a DELTA 3 with 1024 Wh during the day or charge a RIVER 3 Plus several times. Two panels in series roughly double that figure. The calculator above this description works it out for your station.
Who it is for
- RIVER 3 Plus, RIVER 3 Max and RIVER 2 Pro owners: one panel fills their 220 W solar input.
- DELTA 2 and DELTA 3 owners who want to start with one panel and add a second later.
- A country house and road trips, where the panel is unfolded and folded often.
- A backup during power cuts, when the station with a fridge and router needs charging during the day.

Tips for use
Unfold the panel completely and set it up in an open spot without shade. Even the shadow of a branch on one section noticeably reduces the current. Turn the panel towards the sun two or three times a day using the angle guide. For bifacial generation, set it over a light surface. After use, wipe the surface and fold the panel when dry.
Frequently asked questions
How is it different from the NextGen 220W Bifacial?
Both are 220 W bifacial panels. The Lightweight is lighter and has a built-in XT60 cable, a built-in stand and a solar angle guide. The NextGen 220W uses a separate Solar-XT60i cable.
Does it charge a RIVER 3?
Yes, the voltage fits, but the RIVER 3 draws up to 110 W from solar. If you have a RIVER 3 or RIVER 2, the 110W Lightweight is the better buy.
How many panels does a DELTA 3 need?
The DELTA 3 input accepts up to 500 W. Two 220W Lightweight panels in series give 440 W and 42.8 V within the input; they are connected with XT60 – MC4 adapters. This is the optimal setup for a country house.
Can I use it in winter?
Yes. Cold does not harm the panel, and in frost the cells even work more efficiently because they do not overheat. There is less sun, so set the stand to 60 degrees and turn the panel more often.
Can I charge the station and use it at the same time?
Yes. EcoFlow stations support pass-through charging: the panel charges the battery while connected devices keep working. If consumption exceeds what the sun provides, the station takes the difference from the battery.
The manufacturer warranty on the EcoFlow 220W Lightweight Solar Panel is 5 years under the EcoFlow Europe policy, with service handled by EcoFlow in the EU.
