Lots of discussion of this in other comments in this thread, but at least theoretically, for a system of the same size, a change from 20 to 25% efficiency would reduce: the number of frames to manufacture, the weight of the transported goods, the number of panels needed to be installed, and the space needed all of which do plausibly reduce the total cost and time to deploy, no? That change is itself a 25% performance improvement (over the 20% baseline), meaning you need significantly less space and potentially weight/labor to install. Obviously we aren’t making that jump all at once.
