EcoFlow · 220 W folding panel, bifacial
EcoFlow NextGen 220W Bifacial solar panel
220 W, 15.4 lb, folds to 24.2×23.2×1.3 in/615×590×32 mm. $399 at EcoFlow, checked Oct 11, 2026: $1.81 per watt. It charges 95 of the 105 stations we have solar limits for, 15 of them EcoFlow's. The fastest refill from one input: the EcoFlow RIVER 3 Plus, 1 panel, about 1.3 h of full sun.
From EcoFlow's published figures and our own arithmetic; we have not tested it ourselves.

On a -10 °C (14 °F) morning one panel's open-circuit voltage rises to about 23.4 V. That is the figure each station's limit is checked against.
Which stations it charges
One input of each station, the arrangement that takes the most with the fewest panels; fastest refill first. Its maker names no MC4 plug, so it links to other panels only through the maker's own adapters and is counted one panel to an input.
