We really don't have a shortage of space to put solar panels. The challenge is making solar panels that are cost effective (e.g. $ per Watt).

In response to your edit: That is a possibility, that yes they may find a niche in the fancy of the rich.

But the point I'm making is that the article is hyperbolic and misleading.

Transparent solar is not the future of utility scale power generation. It is not going to solve any of the problems currently holding back solar power from becoming ubiquitous.
