I mean, don't airships also have the advantage of not needing to expend energy for lift, just forward motion? A solar plane doesn't have to worry about this either I suppose, but an airship is much easier to make have useful cargo capacity than a solar plane.
Neither do naval ships.
I can only see this being useful over land and short distances.
