Vietnam 1,800 m FRP Solar Roof Walkway Project
This rooftop PV access project was supplied with 500 FRP grating panels, short support rails and roof-fixing hardware. The documented panel size is 3,600 × 1,220 × 38 mm, giving 1,800 m of nominal panel length before site cuts, turns and transitions.
Documented Supply Scope
The project record provides panel dimensions, quantities and the main support hardware. This case study keeps those project-specific figures separate from general product claims or universal installation rules.
Maintenance Route Through the PV Array
On a large commercial roof, the walkway needs to connect the areas technicians actually service. Route planning therefore has to be coordinated with the PV layout, roof structure, access points and rooftop obstructions rather than treated as a separate line item.
Route planning checks
- Service access: connect the PV areas and equipment that require routine inspection or maintenance.
- Roof structure: coordinate support locations with the actual roof construction and approved fixing detail.
- Obstructions: account for vents, skylights, plant equipment and other rooftop features.
- Transitions: plan turns, endpoints and changes in level before panel cutting begins.
- Site access: connect the walkway route to practical roof entry and maintenance points.
Walkway Panel Specification
The documented walkway sheets are Fiberglass Reinforced Plastic (FRP) panels. The project record lists two mesh options and a panel weight per square metre.
Panel data from the project record
- Material: Fiberglass Reinforced Plastic (FRP)
- Panel size: 3,600 × 1,220 × 38 mm
- Mesh options: 38 × 38 mm or 40 × 40 mm
- Listed weight: 19.5 kg/m²
- Project quantity: 500 panels
Support Rails and Roof Connections
The supply list also includes short rail sections, connection components and self-tapping screws. These quantities describe this project only; they should not be reused as a spacing rule for a different roof.
Documented hardware
- Support rail size: 41 × 41 × 2.0 × 400 mm
- Support rail quantity: 244 pcs
- Self-tapping screws: M6.3 × 60
- Screw quantity: 488 pcs
- Other hardware: connection components included
Plan the Full Route Before Cutting Panels
A long rooftop access route is rarely a single uninterrupted straight run. Coordinating the route before installation helps keep panel cuts, support positions and transitions aligned with the actual maintenance path.
Items to confirm on site drawings
- PV layout: module rows, service corridors and equipment zones
- Roof construction: suitable support and fixing locations
- Obstructions: vents, skylights and rooftop plant
- Route geometry: straight runs, turns and endpoints
- Panel cutting: lengths required around site geometry
- Access points: roof entry and maintenance approach
What This Project Illustrates
Access planning belongs in the roof layout
The walkway route needs to be coordinated with the solar array and maintenance points so technicians can reach the areas they need to service.
Panels and supports work as one assembly
The grating panels, support rails, connection components and roof fixings have to be considered together when the installation detail is developed.
Large quantities require route-level coordination
With 500 panels in the supply scope, sequencing, cutting and transitions need to be planned across the full roof instead of panel by panel.
