/PRNewswire/ — JA Solar, a trusted global green energy partner, has hosted a new edition of its Power Talk webinar series, highlighting one of Europe’s most iconic solar energy projects: the photovoltaic installation at SIGNAL IDUNA PARK, Borussia Dortmund stadium.
JA SOLAR Power Talk Webinar Showcases Landmark PV Project at Borussia Dortmunds SIGNAL IDUNA PARK
Certified by RID as the world’s most powerful photovoltaic system on a stadium roof, the project represents an important step in the integration of photovoltaic technology into large-scale urban infrastructure. More than 11,000 JA Solar full-black modules now cover the stadium roof, producing more than 4GWh of clean electricity per year and reducing CO₂ emissions by around 1,700 tonnes per year. The installation demonstrates that high-performance photovoltaic solutions can be deployed on iconic sites while meeting strict architectural, security and operational requirements.
Webinar speakers took the history of the project from design to commissioning, emphasizing the importance of preliminary feasibility studies, long-term planning and close collaboration between stakeholders. They highlighted the logistical and technical challenges of working in one of Europe’s busiest stadiums, where construction had to align with a busy calendar of sporting and non-sporting events, strict safety standards and variable weather conditions.
Beyond energy production, the installation constitutes a powerful sustainability intention. With millions of visitors and viewers each year, SIGNAL IDUNA PARK is an unrivaled showcase for presenting the energy transition and demonstrating how professional sport can actively support climate goals.
For JA Solar, this project is a flagship reference in the provision of photovoltaic solutions for complex and prestigious environments. It illustrates the company’s ability to guarantee reliable products and high-performance modules for demanding applications, opening new possibilities for integrating photovoltaic energy into public infrastructure and sports venues in Europe and beyond.
The webinar featured Petra Zelenická, Head of Marketing and Market Research Europe at JA Solar, Florian Demnitz, Head of Energy at Borussia Dortmund and Christoph Kielhorn, Project Manager PMO Battery Development at RWE. The session was moderated by Gianluca Michieletto, Head of Marketing and Social Media at JA Solar.
