Solar Carport Mounting System: Design and Selection Guide
Evaluating a solar carport mounting system? Verify the parking use, structural load path, foundation, drainage, module layout and installation documents before approving a design.
Requirements for a Solar Carport Mounting System
The mounting system is part of a larger canopy package. It must work with the parking structure, foundations, PV modules, cable management, drainage and local approval requirements.
- Layout: define bay dimensions, vehicle circulation, headroom, posts and maintenance access.
- Load path: identify the canopy members, connections, columns and foundation reactions used in the design.
- Roof and drainage: confirm canopy slope, water collection, discharge points and interfaces with adjacent pavement.
- PV arrangement: confirm module orientation, tilt, shading, inverter locations and cable routes.
- Materials: check material compatibility, corrosion environment, fasteners, finishes and replacement scope.
Selection Criteria for Carport Mounting Systems
Structure-only, PV mounting and integrated packages
| Package | What it can cover | Questions to ask |
|---|---|---|
| Structure-only | Columns, beams, canopy framing and foundations or foundation interfaces. | Who designs the PV attachment, drainage, cable routing and electrical coordination? |
| PV mounting package | Rails, clamps, fasteners, module support and related installation details. | How does it connect to the canopy and what structural assumptions apply? |
| Integrated package | Coordinated structure, PV mounting, drawings, BOM and installation documentation. | Which calculations, site inputs, exclusions and approval documents are included? |
Practical Recommendation for a Supplier Review
Compare suppliers on the same drawings, design conditions and deliverable list. Require a written statement of the load path, foundation assumptions, waterproofing or drainage detail, material specification and installation boundaries before treating a proposal as comparable.
