Renovated Beijing Workers' Stadium sets record for most photovoltaic panels

After its comprehensive renovation last year, the roof of Beijing Workers' Stadium set the record for having the most solar panels of any stadium in China.

This stadium's solar system, comprising 351 kilowatts of photovoltaic modules, was supplied by LONGi Green Energy Technology, a Chinese solar technology company.

Installed along the stadium's roof, the photovoltaic modules form a golden collar encircling the venue, spanning an area of 3,712 square meters.

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."

One of the primary challenges was the stadium's large curved roof, which required the use of custom-designed photovoltaic components, according to Guo. In total, the project utilized 129 unique component sizes to accommodate the roof's intricate geometry.

Originally built in 1959 and spanning over 80,000 sq m, the Workers' Stadium has hosted numerous international sports and entertainment events. The renovation project, launched in 2020 by the Beijing government, was designed to align with the city's urban development goals.

By integrating modern sustainability features with the original architectural design, the updated stadium underscores its cultural and social significance while showcasing the potential of green technology in building construction.
