A 343 kWp distributed rooftop solar project on an aging metal roof.
The Zhaoyi Furniture project uses a distributed PV solution on a metal roof with an installed capacity of around 343 kWp. The roof area is about 1920 m² and the system uses 528 modules of 650 W each.
343 kWp metal-roof project · completed · owner invests zero capital
Installed scale: 343 kWp
Module configuration: 528 modules of 650 W
Project type: commercial / industrial distributed rooftop solar
Energy model: self-consumption, surplus exported to grid
Investment model: owner invests zero capital, project financed and built by our side
Building type: furniture factory building
Roof type: metal roof
Roof area: approx. 1920 m²
Construction condition: lifting and site access were broadly unconstrained
Roof treatment: the aging metal roof was structurally reviewed and upgraded with an added metal-sheet layer before rails and modules were installed
The project uses a rail-mounted installation system on the metal roof.
On an aging metal roof, the project combines an added roof layer, optimized inverter placement, cable-tray routing, and smart monitoring to improve safety, code compliance, and long-term.
For an aging metal roof, the project integrates array design, construction organization, electrical O&M logic, and investment delivery into one.
The roof is a metal-roof factory building of about 1920 m².
The project uses 528 modules of 650 W with a total installed capacity of about 343 kWp, based on a rail-mounted system on the metal roof.
All project cables are routed through trays, resulting in a cleaner, safer, more waterproof, and more standardized electrical path.
This project is financed and built by our side, without energy storage, under a “file first, build second” implementation path.
