SoliTek Photovoltaic Noise Barrier Installed in Italy

A new solar-integrated noise barrier pilot has been completed along the E80 highway near Rome, adjacent to the ANAS Smart Road Center, incorporating high-efficiency bifacial photovoltaic modules supplied by SoliTek. The installation, developed by ANAS in cooperation with GSM Continental as the main contractor, demonstrates how sound-mitigation structures can also contribute to renewable energy generation.

The project integrates 45 SoliTek B108 435 W glass–glass bifacial modules into sound-absorbing aluminum panels, forming a 100-meter section of reconstructed noise barrier. The system reaches an installed capacity of 19.575 kW, with an estimated annual production of 18,283 kWh.

Project specifications:
• Barrier length: 100 m (45 × 2.24 m)
• Number of modules: 45
• Technology: SoliTek bifacial glass–glass modules (B108 435 W)
• Installed capacity: 19.575 kW
• Estimated annual production: 18,283 kWh

ANAS, Italy’s national road infrastructure operator responsible for more than 32,000 km of roads and highways, initiated the project aimed at testing innovative solutions for modernizing noise-barrier infrastructure. The objective was to evaluate concepts that combine acoustic performance with sustainable on-site energy generation as part of the ANAS Smart Road program.

GSM Continental, acting as the main contractor, managed the engineering design, system integration, and installation works. SoliTek supplied the bifacial photovoltaic modules and provided technical input to ensure optimal energy performance, structural compatibility, and long-term durability within the noise-barrier system.

Over the next 12 months, ANAS will monitor the pilot installation to assess energy output, maintenance requirements, and overall system behavior. The insights gained will support future considerations for broader deployment of solar-integrated noise barriers across the national road network.

The final installed capacity of 19.575 kW corresponds to the 43 barrier segments suitable for photovoltaic integration, maximizing renewable energy production within existing structural constraints.
