A hybrid rooftop solar project combining concrete and metal-roof areas.
This project has an installed capacity of around 210 kWp and a total roof area of about 1200 m², combining concrete roof and metal-roof sections.
A quick summary of project type, roof combination, and the key site constraints.
Installed scale: approx. 210 kWp
Project type: commercial / industrial rooftop solar
Energy model: self-consumption
Investment model: self-built · self-invested · self-operated
Status: grid-connected and operating
Total roof area: approx. 1200 m²
Concrete roof: approx. 520 m²
Metal roof: approx. 680 m²
Structural form: sunroom structure + metal-roof combination
The project uses a framed sunroom structure as the unifying logic across different roof conditions.
Under constrained lifting conditions, a sunroom-style structure turns fragmented roof zones into one coordinated system.
Focus: structural unification, array layout, and long-term operating logic under constrained site conditions.
The project is located in a dense urban-village environment where road access and lifting conditions are restricted, increasing construction complexity.
A sunroom-style structure is used as the main unifying system, integrating different roof conditions into one continuous usable space.
Inverters are positioned according to site conditions, and cable routing is organized through trays for a cleaner and safer electrical path.
The project is self-invested, self-built, and self-operated, without energy storage.
