A 46-module roof-layout reference for a standing-seam metal roof application in South Korea. It documents the array geometry and mounting path while keeping site wind, snow, roof-seam compatibility and structural checks project-specific.
What the 46-Module Drawing Establishes
The useful information in this reference is the module count, module format, total DC capacity and array geometry. These values can be carried into an early roof-layout study only when the proposed module dimensions and available roof area remain compatible.
Array geometry
The drawing can be used to discuss how 46 modules fit into an irregular roof area. It should not be treated as a final construction layout without field dimensions.
Mounting path
The concept follows a seam-clamp-to-bracket-to-rail-to-module load path. Final clamp type, spacing and rail spans depend on the actual roof and engineering inputs.
Site verification
Wind, snow, roof-sheet capacity, seam geometry, purlin/support conditions, setbacks and module clamp zones must be checked for the actual building.
Layout Inputs That Can Be Read Directly from the Concept
This section keeps only the information that is visible in, or directly derived from, the reference layout. It intentionally avoids assigning unverified Korean wind, snow or roof-profile values.
Roof-context image. Final attachment selection must be based on the actual seam profile and roof construction.
Reference project data
- Module power: 370 W
- Module quantity: 46
- Reference capacity: 17.02 kW
- Reference array: 8 × 6 minus 2
- Roof type: Standing-seam metal roof concept
- Mounting path: Seam clamp + bracket + rail
How the Roof-to-Module Connection Is Intended to Work
For a compatible standing-seam roof, a seam clamp can provide a non-penetrating attachment to the raised seam. The rest of the mounting assembly transfers module loads through the bracket and rail system. Compatibility and load capacity must be verified for the selected roof panel and clamp.
Seam clamp interface
The clamp must match the actual seam geometry. Clamp approval should be based on the roof-panel profile, material, seam-forming method and project load demand rather than a generic seam width or spacing value.
Rail and bracket interface
The bracket and rail distribute module reactions between attachment points. Final rail span, splice position and attachment spacing should be determined from the actual loads and the selected mounting components.
What Must Be Verified Before the Reference Becomes a Buildable Design
The following items are more important than copying a wind or snow figure from the source drawing. They determine whether the same 46-module concept can be used on the actual roof.
- Roof geometry: field dimensions, usable roof area, obstructions and drainage paths.
- Seam compatibility: seam shape, height, width, fold geometry and roof-panel manufacturer information.
- Structural support: roof sheet, clips, purlins or other supporting members and their allowable capacities.
- Environmental loads: site-specific wind and snow inputs under the applicable local design basis.
- Module requirements: approved clamp zones, orientation, edge distances and manufacturer installation limits.
- Access and setbacks: fire, maintenance, roof-edge, drainage and other project-specific clearance requirements.
Keep the Array Logic; Recalculate the Building-Specific Details
A regional adaptation should preserve only the parts that are genuinely transferable. Everything controlled by the actual building or site should be redrawn or recalculated.
Concept plan used to illustrate the adaptation process; final dimensions and attachment positions belong to the project-specific drawing set.
| May remain as a reference | Must be project-specific |
|---|---|
| 46-module target count | Actual roof outline and usable area |
| 370 W/module capacity assumption | Selected module dimensions and clamp zones |
| 17.02 kW arithmetic | Wind, snow and structural design inputs |
| Seam-clamp / bracket / rail concept | Clamp model, attachment spacing and rail spans |
| General array organization | Setbacks, access, obstructions and drainage clearances |
Need This Layout Adapted to an Actual Metal Roof?
Provide the roof dimensions, seam profile, module datasheet, roof-support information, building height, site photos and project wind/snow design inputs. The mounting layout can then be checked against the real building instead of copied from the reference drawing.
