The Holy See will be adopting solar panels many of its buildings, in accordance with the wishes of Pope Benedict XVI who has "concern about conserving
the Earth’s resources". First in line is the Pope Paul VI auditorium, which seats 6,300 people.
"The roof of the Paul VI auditorium will be redone next year, with its cement panels replaced with photovoltaic cells to convert sunlight into electricity," engineer Pier Carlo Cuscianna said.
The integrated PV cells will provide enough electrical power to provide illumination and temperature control for the auditorium. When not in use, excess power will be fed into the Vatican’s grid.
