Could Tower of London (White Tower) go solar?

The White Tower — the Norman keep that gives the Tower of London its name — is compact by the standards of this list, its four-turret roof covering just under 1,000 sq m. Even so, that measures a theoretical 142 kWp, some 350 panels and 110,000–135,000 kWh a year. As a World Heritage Site and scheduled monument, it's a figure for curiosity alone.
