It might be interesting for rooftop solar where space is limited and installation costs make up a large part of the expense.

It’s likely going to make your roof much heavier though, being made of glass. And that’s usually a bad thing.

So unless they find a different lighter material with which they can create the same kind of lens, it probably won’t be suitable for many kinds of roofs.

I don't know where you live, or what your roofs are made of. But the 1.6m x 1m panels we have weigh only 20KG.

That's much lighter than the tiles they replaced.
