EcoFlow NextGen 220W Bifacial Portable Solar Panel - 25% Efficiency

EcoFlow NextGen 220W Bifacial Portable Solar Panel folds into a compact black case before opening into a long, two-sided panel for portable power stations. Its front side is rated at 220W, while the rear side is rated at 175W, giving the panel a design built around direct and reflected sunlight.

Power And Panel Design

The panel uses N-type TOPCon monocrystalline silicon and lists 25% conversion efficiency. EcoFlow rates the front side at 220W plus or minus 5W and the rear side at 175W, while the photovoltaic connector is designed for portable power-station use.

The folded dimensions are 24.2 by 23.2 by 1.3 inches. Open, the panel measures 24.2 by 84.8 by 1.0 inches and weighs approximately 15.4 lb. Its IP68 rating covers water and dust resistance, and the panel's open-circuit voltage is 21.5V.

Independent Test Results

OutdoorGearLab measured 193 watts from the EcoFlow NextGen 220W during its comparison test. The same test recorded 88% measured efficiency and placed the panel against several 200W folding alternatives.

The test also recorded a measured weight of 16.5 lb with the carrying case, compared with EcoFlow's approximately 15.4-lb panel specification. Its comparison table lists a one-year warranty, a 70-second assembly time, and the ability to daisy-chain panels.

Compatibility And Protection

EcoFlow identifies the panel for use with portable power stations, including the company's DELTA and RIVER product lines. The photovoltaic connector and the station's input requirements must match before operation, because the panel itself is a charging source rather than a standalone battery.

The IP68 rating gives the panel a defined protection class for water and dust exposure. The operating specification lists an optimal voltage of 18.4V, a short-circuit current of 12.4A, and a recommended ambient-temperature range from -4°F to 185°F.

Price And Warranty

EcoFlow lists the NextGen 220W Bifacial Portable Solar Panel at $399.00 as of 09/24/2026. The same listing identifies a 12-month US warranty.

OutdoorGearLab lists a $649 price for the tested model and measured 193 watts during testing. That comparison places the panel's rated output above the 200W alternatives in the same test, although the measured result remains below the 220W nameplate rating.

Who It Fits Best

The EcoFlow NextGen 220W is a portable solar panel for owners of compatible EcoFlow power stations who want more rated output than a 200W folding panel. Its 15.4-lb panel weight, 84.8-inch unfolded length, and one-year warranty are practical limits for frequent carrying, long-term outdoor storage, and demanding travel use.
