Fig. 11.12 PV noise barrier located on the A22 motorway and protecting the village of Marano
(Trento, Italy) from noise pollution. The PV plant has a nominal capacity of 730 kW and was
connected to the grid in 2009. Credits: Autostrada del Brennero Spa
Plant description: The plant is consists of 3,944 mono-crystalline modules
covering a surface of ~5000 m
2 . The PV barrier is displaced along the western
carriageway of the motorway with an extension of 1.07 km and a height of
5.6 m. It has a variable orientation (along the carriageway) and two different
tilts (35° and 60°, a compromise between acoustical and energy-yield performance). The modules are fully integrated into the noise barrier and constitute
the sound absorption element. The plant generates on an average 690,000 kWh
per year, enough to cover the annual electricity needs of approximately 600
households of the closest villages.
Box 13–Solar on a waste water treatment plant
See Fig. 11.13.
Plant description: This plant consists of 1,320 polycrystalline modules
and is integrated into a retractable solar folding roof that can use the open
basins of a waste water treatment plant to generate solar power. Key features
are: extreme lightweight design, wide pole distance and retracting function to
access the basins any time by crane. Waste water treatment plants have very
