Those are concentration mirror, they reflect light onto the spire in the middle which had a receiving element at the top. Conventially they're used for thermal application where you use the sun to generate steam at the top of the tower, although there has been research into beam down variants where the light is reflected down to a very high efficiency PV cell.
