مشروع الطاقة الشمسية الموزعة على سطح مصنع منطقة تشجيانغ تشنهاي الصناعية في تشجيانغ تشنهاي
Project Type: Large-scale Industrial & Commercial Rooftop Distributed Solar Power System
Installed Capacity: 3000KW
Project Overview
Located in Zhenhai Industrial Zone, Ningbo City, Zhejiang Province, this project
provides efficient rooftop distributed solar power solutions for multiple
manufacturing enterprises within the zone, covering 12 large industrial factory
buildings. The project fully utilizes Zhenhai’s superior geographical location
and abundant solar resources, employs high-efficiency monocrystalline silicon
PV modules and advanced intelligent management systems to achieve a
“self-consumption with grid feed-in” green energy model, setting new benchmarks
for industrial & commercial distributed solar applications in the Yangtze River
Delta region and supporting Zhenhai Industrial Zone’s carbon peak and carbon
neutrality goals.

Customer Testimonial
The Zhenhai solar project has brought us dual value. On one hand, it
has significantly reduced our production electricity costs, and on the other hand,
it has enhanced our company’s green image. The Jia Mao team provided professional
anti-corrosion and anti-salt spray solutions tailored to our special coastal
environment needs, and the system operates very stably. Now we have not only
achieved substantial reductions in electricity costs but also gained more business
opportunities through green manufacturing.
