With a capacity of 47.9 kWp, the system is projected to generate about 58,856 kWh in its first year, supplying power to parts of the embassy complex, including the ambassador’s residence and the adjacent main office building.
“Switzerland gives very high priority to energy-saving and sustainable buildings” said Swiss Ambassador to China Jürg Burri. “This year, we've taken many measures to make this embassy green.” We have high energy consumption at the embassy. With conventional measures, we could only cut that by 20 percent, maybe less. Adding photovoltaics helps us make a real, substantial difference.”
Situated in Beijing’s Chaoyang District, the nearly 50-year-old embassy building demanded more than just technical compatibility. GoodWe’s Galaxy Series offers high performance while seamlessly integrating with the architectural integrity and visual harmony of the historic site.
“While we're making this embassy green, we must respect it as a historic building” added Ambassador Burri. “We were looking at the product which is not changing the optics or the aesthetics of the embassy too much.”
Weighing just 5.6 kg/m2, the solar panel array significantly reduces structural load. Its frameless, waterproof membrane-integrated design allows for a clean, unified integration with the existing architecture.
According to GoodWe, the supplied Galaxy series was customised to integrate with the existing Sika-made waterproof membrane in the rooftop, preserving its structure and function.
Blending seamlessly into the embassy environment, GoodWe’s SDT series commercial string inverter is also a natural fit. It offers not just reliable energy conversion but also helps preserve the calm atmosphere essential to the spaces. The 40kW model used in this project emits less than 45 decibels during operation, ensuring minimal acoustic impact. As the first commercial inverter globally to receive TÜV’s low-noise certification, the SDT series has become a trusted solution for noise-sensitive sites such as schools, hospitals, and government buildings.
To meet the embassy’s unique requirement for remote monitoring from its headquarters in Switzerland, the project integrated the Swiss-made data logger, with engineers from both sides collaborating to ensure protocol compatibility.
