1.2MW Connected Factory Rooftop PV Project Huzhou
1.2MW Connected Factory Rooftop PV Project Case, Huzhou, China
1. Project Overview
Location: Distributed solar power station on multiple connected factory rooftops of industrial park, Huzhou, China
Key Parameters:
•Installed Capacity: 1.2MW
•Total Power Generation in 25 Years: 32GWh
•Standard Coal Saved Over Full Lifecycle: 390 tons
•Total CO₂ Emission Reduction: 1,000 tons
This solar project covers rooftops of multiple connected factories in the industrial park. It adopts self-consumption & surplus power grid feed-in mode, greatly cutting industrial power costs for park enterprises and supporting the whole park’s green low-carbon upgrading.
2. Standard 7-Step Service Process
1. Demand Survey
Full-site inspection of roof load, shading and available installation area of all factory buildings. Analyze overall industrial power load of the park and local grid policies to confirm the 1.2MW large-scale capacity plan.
2. Custom Solution Design
Zoned layout design for PV arrays, matched with high-power industrial inverters and heavy-duty anti-corrosion roof brackets. Calculate 25-year power revenue, coal savings and carbon reduction data, deliver complete construction drawings & benefit reports.
3. Custom Equipment Supply
Mass customized high-power PV modules, industrial inverters and non-damaging roof clamps. All auxiliary electrical materials meet national standards with full factory insulation & voltage resistance testing before delivery.

4. On-site Construction
Roof waterproof reinforcement, mass bracket installation by zones, AC/DC cable tray routing and full-park lightning protection setup, fully compliant with industrial high-altitude safety codes.
5. System Commissioning
Zonal group-by-group power testing, unified cloud intelligent monitoring platform deployment, full pre-grid self-inspection and coordination with local power bureau for acceptance.
6. Project Handover
Assist with grid connection filing, hand over complete as-built drawings, equipment certificates and O&M manuals. Provide professional operation training for park electricians and sign completion confirmation.
7. Long-term O&M Support
Monthly full-park inspection,cloud remote fault alarm, original manufacturer warranty repair for core equipment, and annual comprehensive report covering power output, cost savings & carbon reduction data.
3. Comprehensive Benefits
Economic Benefits
•Solar power prioritized for daytime factory production, drastically reducing expensive industrial peak power bills.
•Extra electricity exported to grid brings steady long-term extra revenue for the whole park.
•25-year system service life offsets the rising trend of industrial electricity prices.
Environmental Benefits
Over 25 years, the system saves 390 tons standard coal and cuts 1,000 tons CO₂ emissions, lowering discharge of dust and sulfur pollutants. It meets green park rating and corporate carbon audit standards, improving the park’s attraction for eco-friendly manufacturers.
4. Project Summary
This 1.2MW rooftop PV project for connected factories in Huzhou follows our standardized closed-loop 7-step service workflow, perfectly suitable for multi-building industrial parks. It solves two core pain points of manufacturers: high energy costs and park-wide low-carbon upgrading demand, serving as a benchmark case for large distributed solar projects in industrial parks nationwide.
