Sustainable Solar Street Lighting for Industrial Park in China
In 2022, a large-scale industrial park in eastern China partnered with Queneng Lighting to upgrade their outdated outdoor lighting system with smart, energy-efficient solar street lights. The initiative was part of a wider infrastructure modernization plan to improve safety, reduce long-term energy costs, and promote green energy practices in line with China’s carbon neutrality goals.
🏗️ Project Background:
The industrial park, home to over 50 manufacturing and logistics enterprises, spans more than 30 hectares. Previously reliant on high-maintenance traditional lighting and vulnerable power cables, the park management was facing challenges such as:
-
High nighttime electricity bills
-
Frequent maintenance and outages due to aging grid infrastructure
-
Safety concerns in poorly lit loading zones and roadways
-
Environmental pressure to cut carbon emissions
The management decided to adopt solar-powered outdoor lighting as a solution that aligned with their goals for operational efficiency and corporate sustainability.
