JA Solar has announced a partnership with Borussia Dortmund to install the world’s largest photovoltaic (PV) system on a stadium roof.
The system will be installed on Signal Iduna Park, home to Borussia Dortmund, which holds the highest average match attendance in European football.
The installation is set to position the stadium as a flagship for sustainable innovation.
The project aligns with both JA Solar’s and Borussia Dortmund’s sustainability goals, and it is expected to generate over 4MWh of green electricity annually for the club’s own consumption.
JA Solar will provide more than 11,000 of its Full-Black solar modules for the system, which will help reduce the club’s CO₂ emissions by approximately 1800 tons per year, making the stadium more energy-efficient and resilient.
“This collaboration underlines our commitment to sustainability and innovative technologies,” Carsten Cramer, Managing Director of Borussia Dortmund GmbH & Co. KGaA said.
“With JA Solar’s modules, which will power the largest photovoltaic system on any stadium roof, we are setting the course for a more environmentally friendly future.”
The rooftop system is set to power the floodlights for 1000 matches per year and will serve as a model for other organisations considering the adoption of renewable energy.
Installation is expected to begin in summer 2025, with completion targeted by the end of the same year.
The collaboration also highlights JA SOLAR’s long-term commitment to the European PV market.
The company’s sleek black modules are already popular in private homes for their aesthetic appeal, and this project demonstrates their suitability for commercial applications as well.
