A hybrid rooftop solar project combining rail-mounted metal-roof areas with a framed sunroom structure, where string organization and long-term maintainability are central to the delivery logic.
This project has an installed capacity of around 215 kWp, using a combined solution of metal-roof mounting and framed sunroom-style structure.
A commercial rooftop project delivered under mixed roof conditions with a stronger focus on string logic and long-term serviceability.
Installed scale: approx. 215 kWp
Module configuration: 399 modules of 540 W
Project type: commercial / industrial rooftop solar
Energy model: self-consumption
Investment model: self-built · self-invested · self-operated
Status: grid-connected and operating
Roof type: metal roof + concrete roof
Metal-roof area: approx. 671 m²
Sunroom area: approx. 553 m²
Site condition: rooftop access, lifting, and working area broadly unconstrained
The metal-roof zones use rail-mounted installation, while the sunroom zone uses a 5-degree double-slope framed structure.
The strings are relatively complex, so the real focus is system organization and long-term O&M rather than simple installation speed.
Focus: structure zoning, complex string logic, and long-term operation under hybrid roof conditions.
The project combines metal-roof areas with a framed sunroom structure, creating a mixed structural condition where the roof zones are clearly separated but the string organization.
The metal-roof zones use rail-based installation, while the sunroom area uses a 5-degree double-slope framed structure.
Inverters are positioned close to their relevant roof areas, and all major cable routes are organized through trays to balance waterproofing, safety, and visual order.
The project is self-invested, self-built, and self-operated, without energy storage.
