Photovoltaic

In 2009, in the Municipality of Isera (TN), Autostrada del Brennero built an anti-sound and sound-absorbing barrier on which 3,944 photovoltaic modules are installed. It is 1,067 meters in length and up to 5.6 meters in height, sheltering the town from the noise coming from the tollway and at the same time producing clean energy for the area. This structure guarantees on average an electricity output of around 750,000 kWh per year, which corresponds to the domestic consumption of over 250 families. With regard to the reduction of sound pollution, it produces excellent results during both the day and night: the barrier has significantly reduced the noise from traffic from the section of tollway, by up to 10 dB.
