BERLIN, Nov. 21 (Xinhua) -- Germany's largest football stadium, located in the western city of Dortmund, has completed the installation of what has been confirmed as the world's most powerful photovoltaic (PV) system ever mounted on a stadium roof, the stadium operators said Friday.
The project is part of a sustainability partnership between Borussia Dortmund (BVB), one of Germany's best-known football clubs, and RWE, a major German energy company. The newly completed system consists of 11,132 solar modules with an output of more than 5 megawatts, BVB said in a press release.
The installation is expected to supply up to half of the stadium's electricity needs and cut carbon emissions by about 1,700 tonnes a year.
A 3.7-megawatt-hour battery storage unit is scheduled to be added by early 2026. Once connected, it will enable the stadium to use solar power even when sunlight is not available.
The world record has been confirmed by the German Record Institute.
The announcement comes amid rising public interest in Germany's climate performance. A large-scale study released earlier this month by Germany's Research Institute Social Cohesion found that more than 70 percent of respondents are concerned about the negative effects of climate change, and a clear majority would like policymakers to take more active measures on climate protection. ■
