We could also see them on large buildings or rich people's villas whose owners perhaps want to use energy from solar panels, but don't like the "look" of solar panels on those buildings. So then the choice becomes using this or using no other solar panels.
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.
And the other key challenge is nighttime.
If we had relatively low-cost utility-scale electrical energy storage, we would see a much higher rate of solar energy adoption. More so in sunny places, but that would then drive down the cost for everyone.
I keep hoping something like a flow battery will turn out to be practical, where to size up the storage, you just need bigger storage tanks.
