Cantilever Solar Carport Structures

Single & Double Cantilever Steel Systems for Commercial and Industrial Sites

KLY Solar supplies engineered cantilever solar carport structures for commercial, industrial, and infrastructure-scale parking areas. Installation is typically delivered by EPC/installer partners.


Our systems are available in single cantilever and double cantilever configurations, allowing optimal layout efficiency, reduced foundations, and clear-span vehicle access.

​

Each structure is engineered to site-specific loading requirements and manufactured to UK and EU compliance standards.

Configurations

Single Cantilever Solar Carports

Single cantilever systems use a single row of columns positioned on one side of the parking bays, creating a clear-span canopy over the parking area.

Typical applications:

  • Perimeter parking rows

  • Retrofit installations

  • Sites with underground services or restricted foundations

  • Locations requiring simplified traffic flow

​

Key characteristics:

  • Columns on one edge only

  • Reduced foundation footprint

  • Unobstructed parking bays

  • Efficient for narrow or constrained layouts

Double Cantilever Solar Carports

Double cantilever systems support PV canopies extending in two directions from a central column line, covering parking bays on both sides.

Typical applications:

  • Central car park aisles

  • Large commercial or industrial parking areas

  • High-capacity solar carport projects

​

Key characteristics:

  • Central column row supporting dual canopies

  • Optimised steel-to-coverage ratio

  • Efficient land use

  • Suitable for large-scale PV deployment

Futuristic Car Charging

Structural Design & Engineering

All cantilever solar carport structures are designed by qualified engineers and manufactured using structural-grade steel.

Design considerations include:

​​

  • Site-specific wind and snow loads

  • Foundation reaction forces

  • PV module layout and loading

  • Drainage and cable routing integration

  • Long-term structural durability

Standards & compliance:

​​

  • EN 1090 (CE marked – EXC2)

  • EN 10025 structural steel

  • ISO 1461 hot-dip galvanising

  • Eurocode-based structural calculations

Applications
Philippine Post Office

Cantilever solar carports are commonly specified for:

  • Commercial office developments

  • Industrial and manufacturing facilities

  • Logistics and distribution centres

  • Retail and mixed-use developments

  • Fleet and depot parking

  • EV charging infrastructure projects

Integration with Solar PV & EV Charging

Our cantilever structures are designed to integrate seamlessly with:

​

  • Framed photovoltaic modules

  • Commercial PV mounting systems

  • EV charging points and cable management

  • Future system expansion

  • ​

Layouts can be optimised to balance structural efficiency, energy generation, and parking usability.

Electric Car Charging

Documentation & Project Support

EU and British Flag

Each project is supplied with a comprehensive technical documentation package, including:

​

  • Structural calculations

  • General arrangement drawings

  • Foundation reaction loads

  • Material certificates (EN 10204 3.1)

  • Declaration of Performance (DoP)​

​

This ensures smooth coordination with EPCs, consultants, and local authorities.
