PVNB, or Photovoltaics Noise Barriers, offer a clever fix for two problems at once. These systems cut down noise from busy roads and train tracks while making renewable energy. These installations integrate photovoltaic (PV) panels into noise barriers along highways, railways, and other noisy environments. It helps lower carbon emissions and pushes for more green energy use. By installing solar panels on noise barriers, these structures not only mitigate noise pollution but also contribute to sustainable energy production.
PVNB Sites Around the World
Now let’s explore some PVNB sites that not only reduced the noise pollution but also generated electricity simultaneously.
1. Domat/Ems A13, Switzerland
- Rated Power: 262 kW (repowered)
- Year of Construction: 1989, repowered in 2019
The Domat/Ems A13 is the world’s first PVNB, setting the benchmark for future installations. This pioneering project has demonstrated the reliability and longevity of PVNBs, even in high-dust environments where regular cleaning is not feasible. In 2019, this system was repowered thus able to generate more than 300 MWh of electricity annually.
2. A9 Motorway, Netherlands
- Rated Power: 220 kW
- Year of Construction: 1996
Installed in 1996, it is one of the largest PVNBs in the Netherlands which generates 176 MWh annually with 2160 shell solar cSi solar modules each with a 100 W micro inverter ensuring high system efficiency and reliability. The A9 barrier is a prime example of large-scale PVNB implementation, significantly contributing to the local renewable energy supply.
3. Oppeano, Italy
- Rated Power: 833 kW
- Year of Construction: 2010
The barrier has a zigzag or shingled design with tilted PV modules, around 45°, mounted on a vertical barrier, on the lowest part of the barrier. It holds aluminum cassettes that have good sound-absorbing properties. On the top part standard PV modules are mounted.
4. Marano d’Isera, Italy
- Rated Power: 730 kW
-
Year of Construction: 2009
The main objective of this installation seems to be the production of solar electricity. It has a total length of 1067 m and an average height of 5.6 m. 3944 PV modules were used. According to the specifications, it produces 690 MWh per year.
5. A2 Motorway, Giebenach, Switzerland
- Rated Power: 104 kW
-
Year of Construction: 1995
This PV plant on average produces 850 kWh / kWp. The modules face away from the motorway, it was therefore possible to have a wider and therefore shorter area for the PV array. The plant features PV modules facing away from the motorway, showcasing that the PV array can be installed on either side, one facing the motorway and the other on the opposite wall facing the outside.
6. A27 Motorway, Utrecht, the Netherlands
- Rated Power: 55 kW
-
Year of Construction: 1995
It is the first photovoltaic noise barrier located in the Netherlands. It consists of 1116 modules. The modules were placed on top of the concrete noise barrier with a tilt angle of 50°. The total length of the system was 590 m.
7. Germany, Aschaffenburg
- Rated Power: 2.65 kW
-
Year of Construction: 2009
In Aschaffenburg, Germany, the NBPV system is integrated with a tunnel on the A3 highway, making it the world’s largest PV plant combined with road infrastructure. This installation covers a 2.7 km stretch of the highway and features advanced solar technology. The panels used are high-efficiency monocrystalline modules designed to maximize energy production while minimizing visual and noise impact.
8. The Netherlands, Waalwijk
- Rated Power: 674 kW
-
Year of Construction: 2004
This is one of the biggest PV installations in the Netherlands. Built on a former landfill site, it features 4,212 Shell Solar SQ 160-C WP panels that produce about 600,000 kWh annually. It yields a yearly return of 890 kWh/kWp and serves as a model for integrating renewable energy sources like wind and biomass.
Conclusion
Photovoltaic noise barriers are an effective solution for addressing urban noise pollution while generating renewable energy. These barriers utilise existing infrastructure thereby offering an efficient use of space and resources. As more countries adopt PVNB technology, the global impact on noise reduction and sustainable energy production will continue to grow.
