JA SOLAR, a leading photovoltaic module manufacturer, has partnered with the renowned football club Borussia Dortmund to install a new solar power system on the roof of SIGNAL IDUNA PARK. This project will create the largest photovoltaic system ever built on a stadium roof anywhere in the world. SIGNAL IDUNA PARK, known for hosting the highest average number of spectators per match in European football, will now also set a record for its commitment to sustainable energy.

The project reflects the shared values of JA SOLAR and Borussia Dortmund, emphasizing honesty, respect, and a strong focus on sustainability. With this installation, JA SOLAR will provide high-quality products designed to support decarbonization efforts. The photovoltaic system will generate reliable, eco-friendly electricity for at least 30 years, aligning with the long-term sustainability goals of both partners. It also highlights JA SOLAR’s ongoing dedication to strengthening its presence in the European photovoltaic market.

The solar system will feature more than 11,000 highly efficient Full-Black modules from JA SOLAR, chosen not only for their superior performance but also for their visual appeal, perfectly matching Borussia Dortmund’s iconic black-and-yellow colors. These modules have been widely used on private homes and commercial buildings, thanks to their attractive appearance and compliance with JA SOLAR’s ITS supply chain standards.

Carsten Cramer, CEO of Borussia Dortmund GmbH & Co.KGaA, said in a statement, “We are very pleased to be partnering with JA SOLAR , which will play a significant role in the planned renovation of the photovoltaic system on the roof of SIGNAL IDUNA PARK. This cooperation underlines our commitment to sustainability and innovative technologies. With JA SOLAR solar modules , which will be used in the largest photovoltaic system on the stadium roof, we are showing the way to an environmentally friendly future.”

Henning Schulze, Vice President of JA SOLAR, stated, “We believe that Borussia Dortmund and JA SOLAR share many common values, and we are truly proud that our modules will be used for this project in this iconic stadium. In a time of rapid political change and market difficulties, our participation in this project is a clear statement from JA SOLAR that we are here to stay.”

Once completed, the system is expected to generate over four gigawatt-hours of electricity annually for Borussia Dortmund’s own use. This will help the club significantly reduce its carbon footprint by approximately 1,800 tonnes of CO₂ emissions each year and enhance the stadium’s energy security and resilience. The system will also make it possible to power the stadium’s floodlight system for up to 1,000 matches each year using clean solar energy.

Installation work for the project is scheduled to begin in the summer of 2025, with completion expected by the end of that summer. In addition, JA SOLAR and Borussia Dortmund plan to showcase their collaboration at Intersolar Europe, the leading solar industry trade fair, in Munich from May 7 to 9, where they will welcome visitors at stand A2.280. This project stands as a strong example of how leading sports organizations and energy companies can work together to advance the transition to renewable energy.
