Could Edinburgh Castle go solar?

Edinburgh Castle sits on its volcanic crag as Scotland's best-known fortress, and the roof read here covers the cluster of summit buildings around Crown Square — Google merges them into one. Together they measure close to 8,000 sq m, a theoretical 1.0 MW and roughly 2,500 panels. As a scheduled monument, it's the definition of look-but-don't-touch for solar.
