LEDI Scout SW20 vs Schenker Zen 30
Zen 30 costs 2.7× less energy per litre (3.7 against 10.0 Wh/L). Zen 30 makes 1.5× the water per hour (30 against 20 L/hr).
One side of this comparison rests on a reported figure. LEDI Scout SW20 is published by the manufacturer and corroborated across independent lookups, but we have not yet read the figures page-in-hand the way we have for the rest of the table. The comparison is shown because it is still the best available, not because it is settled. The manufacturer states a draw of 180–220 W; the midpoint is used, matching how we treat published output ranges. How we source figures.

Your boat runs on solar and every watt-hour is spoken for, because this is the cheaper litre to make; you want tanks full in the shortest possible run, or you have a genset that is going to run anyway; you have no generator and no intention of fitting one.
