275.5 kW Metal Roof Triangle Solar Mounting Project in the Philippines
A large rooftop PV mounting project using fixed 15° triangle supports above a metal roof. The supplied engineering drawing shows a repeatable 1 × 23 module table with long aluminum rail runs, module clamps, rail clamps and project-specific roof support connections.
Key Engineering Inputs
The supplied drawing defines the table geometry and structural inputs below. The total project capacity is confirmed as 275.5 kW, while the drawing itself does not state individual module wattage or total project module count.
Repeatable 1 × 23 Module Rows
The engineering drawing uses a long single-row table with 23 modules. The rail length is built from five 4,200 mm sections plus one 2,450 mm section, giving a total longitudinal run of 23,450 mm.
Repeatable 1 × 23 module rows arranged across the metal-roof PV array.
Documented row geometry
- Modules per table: 23
- Table form: 1 × 23
- Rail run: 23,450 mm
- Rail build-up: 5 × 4,200 + 2,450 mm
- Module width: 996 mm
- Module gaps: 22 × 20 mm shown
15° Fixed-Tilt Support Above the Metal Roof
The drawing shows a 1,400 mm triangle base and a 15° module angle. The triangle frame creates a controlled tilt independently of the underlying roof slope.

Why the triangle geometry matters
The support frame controls module tilt, array height and the structural lever arm above the roof. That means triangle spacing, roof attachments and rail connections should be verified together for the project loads.
- Tilt: 15°
- Triangle base: 1,400 mm shown
- Support base detail: 4-M10 shown
- Table support spacing: 19 × 1,200 mm shown
Module Clamp, Rail Clamp and End Clamp Interfaces
The engineering drawing identifies three connection details by name: Inner Clamp, Rail Clamp and End Clamp. These interfaces secure the modules and rails to the triangle structure.
Rail and module connection
Module clamps create the final retention points at the panel frame, while rail clamps connect the rail system to the underlying triangle members.
Roof support connection
The drawing shows a project-specific support base with a 4-M10 fastener pattern. The exact roof-side connection should follow the actual roof profile, support member and waterproofing detail used on site.
What This Philippines Project Shows
Large Roof Projects Benefit from Repeatable Tables
The 1 × 23 row creates a repeatable structural unit that can simplify rail planning, support spacing and installation sequencing across a larger commercial rooftop.
Tilt Changes the Roof Load Path
A 15° triangle frame raises the module plane above the roof, so the rail, triangle, support base and roof structure need to be checked together rather than treating the triangle as a stand-alone accessory.
Wind Input Should Stay Project-Specific
The 2.21 kPa wind-load value belongs to this project drawing. A new Philippines project should be checked using its actual site, building height, terrain, roof geometry and applicable structural requirements.
What to Confirm for a Similar Metal Roof Triangle Project
| Project Input | Why It Matters |
|---|---|
| Module dimensions and clamp zones | Define module support positions and the rail/clamp interface. |
| Metal roof profile | Determines the correct support foot, fastener and waterproofing detail. |
| Roof purlin / structural spacing | Controls where the triangle bases can transfer load into the building. |
| Required tilt | Sets triangle geometry, row height and wind exposure. |
| Wind design basis | Influences rail span, triangle spacing, fasteners and roof reactions. |
| Array layout | Controls the number of repeatable 23-module tables and the final BOM. |
About This 275.5 kW Philippines Metal Roof Project
What installation angle is shown?
The engineering drawing specifies a 15° installation angle for the triangle mounting frame.
How many modules are in one table?
The drawing identifies Array 1 × 23, so the reference table contains 23 modules in one row.
What wind load is shown?
The project drawing lists a wind load of 2.21 kPa. This should not be treated as a universal rating for other projects.
What is the total project module count?
The supplied drawing does not state the total number of modules across the 275.5 kW project, so this page does not estimate it.
Is this a flat-roof ballasted system?
No. The drawing shows triangle frames connected through project-specific support bases/fasteners, so this reference is treated as a mechanically supported metal-roof triangle system.
Can this exact 15° layout be reused?
Not automatically. A new roof should be checked for module size, roof profile, purlin spacing, wind load, attachment details and the required project tilt.
Need a Metal Roof Triangle Mounting Configuration?
Send the module datasheet, roof profile, purlin spacing, preferred tilt, array layout, wind requirements and available roof drawings or photos. We can use them to match the triangle frame, rail, clamp and roof-support configuration.
