The Port of Valencia has begun installing vertical solar panels on its breakwaters under the EU-funded Renewport project. The pilot aims to assess the technical, economic, and environmental viability of large-scale vertical photovoltaics in port infrastructure. Installation is ongoing, with full operation expected by September 2026.
The Port of Valencia is currently 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 because it seeks to reduce the carbon footprint of Mediterranean ports and advance renewable energy deployment in maritime hubs.
The project, launched in January 2024, involves installing 21 photovoltaic modules rated at 410 W each, with a total capacity of 8.6 kW. The work is being carried out by Pavener Servicios Energéticos S.L., with installation expected to be completed and operational by September 2026. The system uses a proprietary matrix solution developed by SunnerBox, designed to leverage existing breakwater infrastructure while minimizing structural costs and simplifying maintenance.
The pilot system is part of a broader effort to validate the technical, economic, and environmental aspects of deploying large-scale vertical PV in port settings. Over a two-month period, sensors will monitor energy generation and structural behavior in real time, with the energy produced powering the sensor system itself. The project also includes installing official signage and promoting awareness of renewable energy initiatives within the port.
Implications for Renewable Energy in Mediterranean Ports
This project represents a step forward in integrating renewable energy solutions into port infrastructure, potentially reducing reliance on fossil fuels and lowering greenhouse gas emissions. Successful deployment could lead to wider adoption of vertical PV systems in other Mediterranean and European ports, supporting regional climate goals and energy transition strategies. Additionally, demonstrating the technical and economic viability of such systems may attract further investment in innovative renewable technologies for maritime hubs.

Renewport’s Role in Mediterranean Port Decarbonization
The Renewport project, co-financed by the European Union through the Interreg Euro-MED programme, aims to support the clean energy transition of Mediterranean ports by testing and validating renewable energy solutions. The Port of Valencia’s initiative builds on prior testing of vertical solar panels on its North Breakwater wall in 2023, which demonstrated the feasibility of such installations. The project aligns with broader EU efforts to decarbonize maritime infrastructure and promote sustainable port operations across the region.
“The installation of vertical PV panels on breakwaters could revolutionize how ports generate renewable energy, leveraging existing infrastructure while minimizing costs.”

Uncertainties Surrounding Long-Term Performance
It is not yet clear how the vertical PV panels will perform over the long term in a dynamic port environment, including their durability, maintenance needs, and actual energy output under varying conditions. The two-month monitoring phase will provide initial data, but full assessment requires longer-term observation.
Next Steps for Valencia’s Vertical PV Pilot
Following installation, the project will monitor the system’s performance until September 2026, with data informing potential scaling and replication. If successful, the port may expand vertical PV deployment and share findings with other Mediterranean ports. Further studies may also explore integrating these systems with other renewable sources like wind or geothermal energy.
Key Questions
What is the main goal of installing vertical PV panels at Valencia port?
The primary goal is to evaluate the technical, economic, and environmental feasibility of large-scale vertical photovoltaic systems on port infrastructure to support decarbonization efforts.
Who is funding and supporting this project?
The project is co-financed at 80% by the European Union through the Interreg Euro-MED programme under the Greener MED initiative, with local partners including Pavener Servicios Energéticos S.L. and the Polytechnic University of Valencia.
When will the project be fully operational?
The installation is expected to be completed and operational by September 2026.
What are the potential benefits of vertical PV systems on port breakwaters?
Benefits include leveraging existing infrastructure for renewable energy generation, reducing the port’s carbon footprint, and demonstrating innovative solutions that could be adopted elsewhere.
Are there any risks or challenges identified so far?
Long-term performance, durability under maritime conditions, and maintenance costs remain uncertain until the pilot has been operational and monitored over a longer period.
