In 2021, a large-scale solar thermal project was successfully implemented in Taihe Swan Castle, a picturesque urban residential community in Qing County, Cangzhou. Surrounded by mountains and water, this scenic development embraced clean energy by installing 3,650 balcony-mounted flat plate solar water heaters for each of its 3,650 apartment units.
Project Year: 2021
Location: Qing County, Cangzhou
Scale: 3,650 households
System Type: Wall-mounted flat plate solar water heater (balcony installation)
By integrating flat plate solar collectors directly onto balconies, the system offers an elegant and efficient solution for modern residential buildings. It provides each homeowner with an independent solar hot water system that is reliable, maintenance-friendly, and environmentally conscious.
Urban architecture often limits the use of rooftop-mounted systems due to shared space and structural regulations. In contrast, balcony solar water heaters offer a flexible solution that fits seamlessly into multi-story apartment buildings.
The flat plate solar water heater system installed in Taihe Swan Castle is designed to:
Capture maximum sunlight from south-facing balconies
Heat water efficiently even during the winter months
Operate independently for each household with easy access
According to post-installation data, the project is expected to save approximately 4.1 million kWh of electricity per year, reducing carbon emissions while significantly lowering energy costs for residents.
That’s equivalent to saving more than 1,500 tons of coal annually, showcasing how urban residential developments can adopt scalable solar heating systems to support national sustainability goals.
