Project facts

What the source information actually documents

The case information provides the array quantity, module dimensions, module weight and several design inputs. It does not provide module wattage, total system capacity, site address, roof pitch, exposure category, risk category or attachment spacing.

Design-basis note: the source also lists ASCE 7-10. This is retained here only as a historical project input. It should not be reused as the design basis for a new project without confirming the current code edition, jurisdictional requirements and site-specific loading criteria.

Array and mounting configuration

Roof hooks, rails and module clamps

The documented mounting concept is a conventional rail-based rooftop assembly. The exact hook geometry, fastener, spacing and waterproofing detail are not established by the case information shown on this page.

Project details

Visible attachment and rail interfaces

The detail images are useful for understanding the physical arrangement of the mounting components. They should not be treated as a complete engineering or waterproofing specification for another roof.

Roof-hook interface

The attachment detail shows the roof-side interface. For a new project, verify the supporting structure, tile clearance, fastener selection and the roof manufacturer's water-management requirements.

Rail and module connection

The project uses rails with module clamps. Clamp location and rail spacing for another project must follow the selected module's approved installation and clamp-zone requirements.

Inputs that should be confirmed before hardware selection

A project reference can show the mounting concept, but hardware selection still depends on the actual roof assembly, structure, module and local design loads.

Installation detail at the roof attachment area.

Tile profile and conditionConfirm the actual tile shape, overlap and available clearance.

Supporting structureConfirm rafters, trusses, deck or other approved structural fixing points.

PV module dataUse the selected module dimensions, frame details and approved clamp zones.

Current design loadsConfirm the applicable wind, snow and other load criteria for the project location.

Attachment spacingDetermine spacing from the project-specific structural design rather than copying this case.

Water managementUse a roof-compatible flashing or sealing detail accepted for the actual roof system.
