JA Solar's Landmark PV Project at SIGNAL IDUNA PARK

In the latest installment of JA Solar's Power Talk webinar series, the global green energy partner unveiled its impressive photovoltaic project located at the SIGNAL IDUNA PARK, home of Borussia Dortmund. This project is hailed as one of the most significant solar energy initiatives in Europe, marking a pivotal moment in the integration of photovoltaic technology into large-scale urban infrastructures.

An Unprecedented Achievement

Certified by RID as the world's most powerful photovoltaic system atop a stadium, this project features over 11,000 sleek black JA Solar modules spread across the stadium's roof. The installation generates more than 4 GWh of clean electricity annually, effectively reducing CO₂ emissions by approximately 1,700 tons each year.

JA Solar's innovative approach showcases how high-performance photovoltaic solutions can be successfully implemented in iconic locations while adhering to stringent architectural, safety, and operational standards. The impressive metrics from this project not only highlight its energy-generating capabilities but also underscore its role as a symbol of sustainability in sports.

Project Journey Revealed

During the webinar, speakers discussed the evolution of the project — from its initial concept to commissioning. They emphasized the importance of early feasibility studies, long-term planning, and close collaboration with stakeholders. The logistics and technical challenges posed by constructing in one of Europe's busiest stadiums were also addressed. Construction activities had to progress in sync with a packed schedule of sporting events and other activities, all under strict security protocols and variable weather conditions.

"The project at SIGNAL IDUNA PARK is a testament to the power of sustainable energy and a clear demonstration of how professional sports can actively contribute to climate goals," stated one of the speakers. With millions visiting the stadium annually, this project provides unparalleled visibility for showcasing the transition to renewable energy.

The Future of Photovoltaic Integration

For JA Solar, this landmark project acts as a benchmark for delivering photovoltaic solutions to complex and high-profile environments. It highlights the company’s ability to ensure reliable supply chains of high-performance products suitable for demanding applications, opening new avenues for photovoltaic integration in public infrastructures and sports facilities both in Europe and worldwide.

The webinar featured insights from key figures in the industry, including Petra Zelenická, Marketing and Market Research Director for Europe at JA Solar; Florian Demnitz, Energy Director at Borussia Dortmund; and Christoph Kielhorn, Project Manager for Battery Development at RWE. The session was moderated by Gianluca Michieletto, Marketing and Social Media Director at JA Solar.
