Brazil 16-Panel Solar Roof Mounting Project
A Brazil solar roof mounting project developed around 16 PV panels in a 2 × 8 layout, using four continuous rail lines, adjustable roof-hook spacing and a rail-and-clamp architecture with AL6005-T5 aluminum and SUS304 stainless-steel hardware.
Tile Roof Mounting Configuration
The engineering drawing is dated 15 May 2019 and identifies a 2 × 8 tile-roof array for a Brazil solar roof project. The matching quotation uses the same rail, clamp and roof-attachment quantities implied by the drawing geometry.
2 × 8 Array with Four Rail Lines
The drawing shows eight modules across the row, two module rows, four horizontal rail lines and an 8,400 mm rail run built from paired 4,200 mm rail sections.
Simplified source drawing crop: Array 2 × 8, 20 mm module gaps, 8,076 mm array width, rail 2 × 4,200 mm = 8,400 mm, hook spacing approximately 1,000 mm adjustable.
Why the layout and BOM match
The component quantities in the project quotation align closely with the 2 × 8 drawing:
- Rails: 8 × 4,200 mm
- Rail Splices: 4 × 200 mm
- Mid Clamps: 28 for 40 mm frames
- End Clamps: 8 for 40 mm frames
- Roof Hooks: 36 SUS304
- Module Gaps: 20 mm shown
From Tile Roof to PV Module
The layout uses a conventional rail-based tile-roof structure. Roof hooks create the primary roof interface, aluminum rails provide continuous module support, and mid/end clamps secure the framed PV modules.
Continuous Rail Alignment
Four long rail lines establish a straight support plane across the 2 × 8 array and provide common clamp channels for the modules.
Adjustable Hook Placement
The drawing marks roof-hook spacing at about 1,000 mm with adjustment, allowing the attachment pattern to coordinate with the actual roof structure rather than a fixed decorative tile spacing.
40 mm Module Clamp Interface
The quotation specifies mid and end clamps for 40 mm module frames, connecting the module frame to the rail as a defined mechanical interface.
Wind, Snow and Material Inputs in the Quotation
The historical quotation provides a product/project screening basis for this Brazil tile-roof mounting package. These values should be treated as archive design inputs, not as universal ratings for every roof or present-day project.
| Quotation Input | Documented Basis | How It Affects the Mounting Review |
|---|---|---|
| Installation site | Tile roof | Drives the use of roof-hook or hanger-bolt attachment concepts rather than ground or flat-roof hardware. |
| Maximum wind speed | Up to 60 m/s | Requires the attachment pattern, rails, clamps and supporting roof structure to be checked together for the actual project geometry. |
| Snow load | Within 1.4 kN/m² | Affects rail span, module support, roof reaction and structural verification. |
| Primary materials | AL6005-T5 + SUS304 | Aluminum rails and stainless-steel connection hardware form the main corrosion-resistant mounting assembly. |
| Rail finish | Anodized aluminum | Matches the natural silver appearance documented in the quotation. |
Roof Hook Layout with an L-Foot / Hanger-Bolt Alternative
The engineering drawing is explicitly based on adjustable roof hooks. The related quotation package also evaluated an alternative L-foot + hanger-bolt solution using the same rail and clamp quantities.
- Rail 4,200 mm8 pcs
- Rail splice 200 mm4 pcs
- Mid clamp for 40 mm frame28 pcs
- End clamp for 40 mm frame8 pcs
- SUS304 roof hook36 pcs
L Foot + M10 × 200 Hanger Bolt
The alternative quotation keeps the same eight rails, four splices, 28 mid clamps and eight end clamps, but replaces the roof-hook set with 36 L feet using M10 × 200 hanger bolts.
The L-foot assembly is documented as AL6005-T5 + SUS304 + EPDM. This illustrates how the upper rail-and-clamp architecture can stay stable while the roof attachment changes to suit a different roof/substructure condition.

Array Geometry Drives the BOM
The rail, splice and clamp quantities can be traced directly back to the 2 × 8 layout. This is why a module-layout revision should trigger a mounting BOM review rather than reuse an old list automatically.
Attachment Can Change Without Redesigning Every Upper Component
The same rail and clamp architecture was quoted with both roof hooks and an L-foot/hanger-bolt alternative, showing how the primary roof interface can be adapted while preserving much of the upper mounting system.
Wind and Snow Inputs Belong to the Whole Roof System
The 60 m/s and 1.4 kN/m² values are documented quotation inputs. A new project still needs site-specific verification of the roof structure, attachment, rail span, module support and applicable design requirements.
About This Brazil 16-Panel Solar Roof Project
How many modules are shown?
The drawing identifies a 2 × 8 array, so the mounting layout supports 16 modules. The source package does not state the individual module wattage.
Why are there eight 4.2 m rails?
The drawing uses four horizontal rail lines, each 8.4 m long. Each line is formed by two 4.2 m rails, which produces eight rail pieces and four splices in total.
Was the roof-hook option the only attachment considered?
No. The drawing uses adjustable roof hooks, while a parallel quotation evaluated 36 L feet with M10 × 200 hanger bolts and EPDM as an alternative attachment concept.
Does the 60 m/s wind value apply to every tile roof project?
No. It is the wind basis recorded in the historical quotation. A new roof project should be checked using its own location, building geometry, roof structure, module, attachment spacing and applicable structural requirements.
Need a Tile Roof Mounting Configuration?
Send the module datasheet, roof tile profile, roof structure or rafter spacing, layout, wind and snow requirements, and available roof drawings or photos. We can use them to prepare a project-specific rail, clamp and attachment configuration.
