100MW PV system for the Vatican
100MW PV system for the Vatican
(OP)
It may not be entirely PV, but seems headed in that direction.

RE: 100MW PV system for the Vatican
"More recently the Vatican has put words into actions.
The 5,000-square-meter roof of the Paul VI auditorium -- built in 1971 by Pier Luigi Nervi, the architect who designed Milan's Pirelli Tower -- was covered with 2,400 solar panels to produce 300 kilowatt hours of energy a year, enough for 100 households, cutting carbon-dioxide emissions by about 225 tons. "
300 kw-hr?
RE: 100MW PV system for the Vatican
Leave it to reporters to screw up the numbers.
$6.6 isn't expensive, if its the installed cost. That would fit up with the MW project costs in the EU, given the panels have recently come down in price a bit. And I think Italy is paying what must be around 0.60 US per PV kWh, so the payout is much less than 20 years. In fact it may be 8 or 9 years, as insolation in the middle latitudes of Italy isn't too bad.

However, the reporter did correctly use kWh and energy.

RE: 100MW PV system for the Vatican
300 kWp x 6 avg stdandard Sun h/day = 1800 kWh/d,
1800 kWh/d x 0.75 eff w/cable & inverter losses = 1350 kWh/d
1350kWh/d / 100 homes = 13.5 kWh/Home-d.
That's pretty much the same as the Spanish national average household consumption, with a lot of LPG usage for heat in the small towns.
It keeps looking like 300 kWp.
