Signal Iduna Park， The home stadium of the legendary BVB in European football. As the largest and most seated professional football stadium in Europe, it is renowned worldwide for its stunning viewing experience and innovative design. Since its opening in 1974, it has hosted top-level events such as the European Championship and World Cup multiple times.

Recently, Rekord Institut f ü r Deutschland officially awarded the venue the world record certification for the "world's most powerful stadium rooftop photovoltaic system". Behind this record is the exclusive empowerment of over 11000 JA Solar DeepBlue 4.0 Pro all black modules, creating a historic milestone in the intersection of professional sports, urban large-scale infrastructure, and renewable energy.

Focusing on the project itself, Signal Iduna Park is most famous for its full station stand design, which can accommodate 25000 fans and is the largest independent stand in Europe. It is also known as the "yellow wall" due to its bright yellow color. Nowadays, the JA Solar DeepBlue 4.0 Pro's all black components and the yellow wall of the stadium logo complement each other, not only adding a scenic line that combines technological beauty and sustainable concepts to this "football temple", but also achieving an annual power generation of over 4GWh (equivalent to meeting the lighting needs of 1000 matches), reducing about 1800 tons of carbon dioxide emissions, and setting a new benchmark for sustainable operation of large public venues.

Since entering the European market, JA Solar DeepBlue 4.0 Pro's all black modules have won wide recognition from home and business users for their outstanding aesthetic design. The joint creation of world records by JA Solar and BVB once again demonstrates the outstanding applicability and competitiveness of JA Solar module products in the European market.Editor/Cheng Liting
