USA 20-Panel Tile Roof Solar Mounting Project
A 20-panel tile-roof PV mounting reference using a conventional roof-hook and rail architecture. The documented layout uses two rows of ten modules, aluminum mounting members and clamp-based module fixation, with ASCE 7-10 listed as the wind-design reference.
Documented Roof-Mounting Inputs
The project information sheet defines the module format, mounting architecture and array quantity. It does not state module wattage or total project capacity, so no kW value is estimated.
Two Rows of Ten Modules
The documented array information uses two segments by ten columns, giving 20 modules in total. This creates a compact roof layout that can be coordinated with roof edges, setbacks and the supporting rafter structure.

- Array:2 × 10
Conventional Roof Hooks with Aluminum Rails
The project note specifically calls for a conventional roof-hook and rail solution. On a tile roof, the hook provides the structural connection below the tile surface while the rail creates the module-support and alignment plane above the roof.
Roof-hook interface
The roof hook should be positioned to transfer loads into the supporting roof structure rather than relying on the tile itself as a structural element.
Rail and module connection
The source describes a clamp-based module-fixing method. Rails align the array and provide the interface for the module clamps.
ASCE 7-10 Listed as the Wind Reference
| Documented Input | What It Means for the Mounting Review |
|---|---|
| ASCE 7-10 reference | The original design information points to a U.S. wind-design basis. |
| 20 panels / 2 × 10 layout | Defines the array geometry used to plan the rails, clamps and attachment positions. |
| 1722 × 1134 × 30 mm modules | Module dimensions affect rail spacing, clamp zones and roof-area requirements. |
| 21.5 kg module weight | Contributes to the gravity load transferred through rails and roof hooks into the building. |
| Conventional roof hooks | The exact hook and fastener must match the tile profile and supporting roof structure. |
Tile Interface, Attachment and Water Management
The most useful detail image for this type of case is the roof interface: how the tile is accommodated around the hook, how the attachment reaches the structural member and how the installation maintains a weather-resistant roof assembly.

What This 20-Panel Tile Roof Reference Shows
A Simple Array Still Needs Structural Coordination
Even a compact 2 × 10 layout depends on the relationship between module size, rail position, hook spacing and the actual roof structure.
Roof Hooks Are Structural Attachments
The hook should transfer load to the building structure while allowing the tile covering to remain properly supported and weather resistant.
About This USA 20-Panel Tile Roof Project
How many solar panels are in the project?
The project information sheet lists 20 modules arranged in a 2 × 10 layout.
What module size is documented?
The modules are listed as 1722 × 1134 × 30 mm with a weight of 21.5 kg each.
What mounting method is used?
The project note specifies a conventional roof-hook and rail configuration with clamp-based module fixation.
What is the snow load?
The snow load is 30 psf.
What wind speed was used?
The wind speed is 115 mph.
Can the same roof-hook layout be reused?
Not automatically. Hook selection and spacing should match the actual tile profile, supporting structure, module layout and project loads.
Need a Tile Roof Solar Mounting Configuration?
Send the module datasheet, roof tile profile, roof structure or rafter spacing, project address, wind and snow basis, and available roof drawings or photos. These inputs can be used to match the roof hooks, rails, clamps and attachment layout.
