Some of the most expensive parts of solar installations these days is the support structure to hold the panels, so a giant air mattress might be cheaper.

This is indeed one of the possible positive points of such a project. An achievement:

Flexible organic solar cells on a balloon (time lapse)

In altitude a lifter kite could be added.
