/PRNewswire/ –JA Solar, a trusted global partner in green energy, hosted a new edition of its “Power Talk” webinar series, highlighting one of Europe’s most prominent solar energy projects: the photovoltaic system at SIGNAL IDUNA PARK, home of Borussia Dortmund.
JA SOLAR Power Talk Webinar Showcases Landmark PV Project at Borussia Dortmunds SIGNAL IDUNA PARK
The project was certified by RID as the world’s most powerful PV system on a stadium roof and marks a milestone in the integration of PV technology into large-scale urban infrastructure projects. More than 11,000 all-black modules from JA Solar now cover the stadium roof and produce over 4 GWh of clean electricity annually, reducing CO₂ emissions by around 1,700 tonnes per year. The installation demonstrates how high-performance PV solutions can be deployed in significant locations while meeting strict architectural, safety and operational requirements.
The webinar speakers followed the project’s journey from concept to commissioning, emphasizing the importance of early feasibility studies, long-term planning and close collaboration with stakeholders. They highlighted the logistical and technical challenges involved in working in one of Europe’s busiest stadiums, where construction work had to be balanced with a packed calendar of sporting and non-sporting events, strict safety standards and changeable weather conditions.
Beyond energy production, the system makes a strong statement for sustainability. With millions of visitors and spectators each year, SIGNAL IDUNA PARK offers unparalleled visibility to showcase the energy transition and show how professional sport can actively support climate goals.
For JA Solar, the project is a showcase for providing PV solutions for complex, high-profile environments. It demonstrates the company’s ability to ensure reliable product supply and high-performance modules for demanding applications, and opens up new opportunities for the integration of PV systems into public infrastructure and sports venues in Europe and beyond.
The webinar offered insights from Petra Zelenická, Head of Marketing and Market Research Europe at JA Solar, Florian Demnitz, Energy Manager at Borussia Dortmund, and Christoph Kielhorn, Project Manager PMO Battery Development at RWE. The event was moderated by Gianluca Michieletto, marketing and social media manager at JA Solar.
