The Solar Building XXI has in the south fagade 96m2 of PV (Polycrystalline), which correspond to 12kWp, plus a 6kWp (Amorphous silicon) in the car parking in front of the building (see figure 12). These two systems are responsible for an overall PV annual production of 12 MWh (in the fagade) plus a 8MWh (in the car parking), which correspond to around 76% of the electricity consumption of the building.
