I think the point is that you can replace one big solar panel with one big lens and a small solar panel. The footprint on the roof is the same, but the implication is a big glass lens is cheaper than a big solar panel.

the glass lens probably is cheaper than a big solar panel
but the cost of setting up a glass lens in 5-10 meters altitude (because that’s what’s needed to bundle any sunlight) is probably more expensive than setting up a big solar panel at hip height.
and considering that labor cost is a significant part (i guess 10% - 50%) of overall solar park cost, i guess it’s probably not worth it.
