This design not only enhances the stadium's appearance but also contributes to its sustainability by partially powering its operations and reducing carbon emissions, according to LONGi. The company estimates that over the next 25 years, the system will reduce carbon emissions by 4,930 metric tons.

LONGi said the installation of the photovoltaic modules was designed to accommodate both functional and aesthetic goals.

"The Workers' Stadium renovation differs from other photovoltaic projects we've undertaken for older buildings," said Guo Hua, vice-president of the photovoltaic systems unit at LONGi. "As the stadium holds cherished memories for Beijing residents, the project was conducted with a protective approach, preserving its original internal and external structures."
