TL;DR
The Port of Valencia is installing vertical photovoltaic panels on its breakwaters under the EU-funded Renewport project. This pilot aims to test the technical, economic, and environmental viability of large-scale vertical PV systems on port infrastructure, with completion expected by September 2026.
The Port of Valencia has begun installing vertical solar panels on its breakwaters as part of the EU-funded Renewport project, marking a significant step toward integrating renewable energy into port infrastructure to reduce carbon emissions.
The project, launched in January 2024, involves installing a pilot system of 21 photovoltaic modules on the North Breakwater wall, with an expected operational date in September 2026. The system has a combined capacity of 8.6 kW, with each module rated at 410 W. The installation is managed by Pavener Servicios Energéticos S.L., with a contract valued at approximately €169,315 ($195,000). The initiative is co-financed at 80% by the European Union through the Interreg Euro-MED programme under the Greener MED scheme.
The project aims to demonstrate the feasibility of large-scale vertical PV systems in port environments, assessing their technical, economic, and environmental impacts. Prior testing in 2023 on a section of the North Breakwater verified the system’s efficiency and installation process, paving the way for this larger deployment.
The PV system uses a proprietary matrix structure developed by SunnerBox, called IT3, which mounts photovoltaic panels on a mesh secured to the breakwater with stays and tensioners. This design leverages existing infrastructure, reduces structural costs, and simplifies maintenance, according to the company.
The pilot will monitor energy generation and structural behavior in real time over two months, with sensors providing data to evaluate system performance. The energy produced will power the sensor system itself, enabling continuous data collection.
Impact of Vertical PV on Mediterranean Ports
This deployment represents a pioneering effort to incorporate large-scale vertical photovoltaic systems into port infrastructure, potentially transforming how ports generate renewable energy. If successful, it could lead to wider adoption across Mediterranean ports, helping reduce their carbon footprint and supporting EU climate goals. The project also offers insights into cost-effective, scalable solutions that leverage existing port structures for renewable energy generation, contributing to the broader transition toward sustainable maritime operations.

Background on Renewport and Vertical PV Trials
The Renewport project, launched in January 2024 and co-financed by the EU, aims to support the clean energy transition of Mediterranean ports by validating innovative renewable solutions such as solar, wind, and geothermal power. The Port of Valencia was among the first to test vertical solar panels on its North Breakwater in 2023, demonstrating the feasibility of this approach. The current installation builds on that initial testing, moving toward large-scale deployment.
This initiative aligns with broader European efforts to decarbonize port operations and expand renewable energy use in maritime hubs. The project also involves collaboration with the Polytechnic University of Valencia’s PRINS research center, which will monitor the system’s performance.
“The vertical PV system leverages existing port infrastructure, which could significantly reduce installation costs and time compared to traditional ground-mounted systems.”
