The Port of Valencia is installing vertical solar panels on its breakwaters under the EU-funded Renewport project. This pilot aims to evaluate the technical, economic, and environmental viability of large-scale vertical photovoltaics in port infrastructure, with installation expected to complete by September 2026.
The Port of Valencia has begun installing vertical solar panels on its breakwaters as part of the EU-funded Renewport project, aiming to demonstrate the feasibility of large-scale vertical photovoltaics in port infrastructure. This initiative is significant for advancing renewable energy in Mediterranean ports and reducing their carbon footprint.
The project, launched in January 2024 and co-financed at 80% by the European Union through the Interreg Euro-MED programme, involves installing 21 photovoltaic modules with a combined capacity of 8.6 kW on the port’s breakwaters. The work, awarded to Pavener Servicios Energéticos S.L. for approximately €169,315, is scheduled for completion by September 2026.
The pilot system utilizes SunnerBox’s proprietary IT3 matrix, which mounts photovoltaic panels on a mesh structure anchored directly to the breakwater, leveraging existing infrastructure to reduce costs and simplify maintenance. The system aims to assess the technical, economic, and environmental aspects of vertical PV deployment in port settings.
Real-time monitoring over the next two months will evaluate energy generation and structural behavior, with the energy produced used to power sensor systems. The project builds on previous testing of vertical panels on the North Breakwater wall in 2023, which demonstrated the feasibility of such installations and paved the way for this larger pilot.
Potential Impact on Mediterranean Port Renewable Strategies
This initiative could set a precedent for Mediterranean ports seeking to integrate renewable energy solutions into their infrastructure, potentially reducing reliance on fossil fuels and lowering emissions. Successful deployment and validation of vertical PV systems may encourage broader adoption across the region, aligning with EU climate goals and port sustainability targets.

Renewport and Vertical PV Development in Valencia
The Renewport project aims to support the clean energy transition of Mediterranean ports by testing innovative renewable solutions, including solar, wind, and geothermal power. Valencia’s port has been a pioneer in this effort, having previously tested vertical solar panels on its North Breakwater in 2023, which demonstrated the practicality of such systems. The current installation marks a significant step toward deploying large-scale vertical PV parks in port environments, supported by EU funding and regional cooperation.

Uncertainties About Long-Term Performance and Scalability
It is not yet clear how the vertical PV system will perform over extended periods or how scalable this approach is for larger installations in other ports. Monitoring results over the coming months will be critical to assess durability, maintenance needs, and overall efficiency.

Next Steps for Validation and Regional Expansion
The project team plans to complete the installation by September 2026, followed by a two-year monitoring phase to gather data on performance and environmental impact. If successful, the results could promote wider adoption of vertical PV systems across Mediterranean ports and inform future renewable infrastructure policies.
