Twice the panel. Twice the potential.
The EcoFlow NextGen 220W Bifacial Solar Panel is the natural companion to the RIVER 3 Plus. It collects energy from both sides, uses the most advanced solar cell technology available in a portable panel, and recharges the RIVER 3 Plus from empty in as little as 1.5 hours. If you're serious about taking steps toward running your home on solar, this is where the setup gets real.
Why It Works for You
Captures energy from both sides: The front collects direct sunlight at up to 220 watts. The back harvests reflected light off surfaces like grass, concrete, sand, or snow, adding up to 28% more energy on a good day. Most solar panels only work from one side.
The most efficient portable panel on the market: The TOPCon cell technology reaches 25% conversion efficiency, meaning more of the sunlight that hits the panel becomes usable electricity
Built-in angle guide takes the guesswork out: An integrated guide shows you exactly how to position the panel for maximum sun exposure, with a 30–60° adjustable kickstand to dial it in
Weatherproof and built for the long haul: IP68 waterproof rating and ETFE coating mean it handles rain, heat, dust, and years of outdoor use without degrading
Lighter than it looks: At 15.4 pounds for the panel, it folds flat and travels easily to a campsite, patio, or car trunk
Works with nearly any power station: Standard MC4 connector is compatible with the EcoFlow RIVER 3 Plus and most other portable power stations on the market
What It Charges
Paired with the EcoFlow RIVER 3 Plus Portable Power Station (sold separately), one full day of sun gives you roughly 880Wh of stored energy, enough to:
- Charge a phone about 65 times
- Run a laptop all day (about 15 hours)
- Power a mini fridge for most of the day
- Run LED lights for several days
- Run a Wi-Fi router for several days
The Lifetime Picture
At an average of 4 peak sun hours per day, this panel generates roughly 8,030 kilowatt-hours over 25 years. At the U.S. average electricity rate, that's around $1,450 in energy value. In higher-rate states like California or New York, closer to $2,710.
Based on a rated output of 220W, 4 peak sun hours/day, 25 years of panel life, and electricity rates of $0.1805/kWh (national average) and $0.3375/kWh (high-rate states).
