Solar Carport Mounting System | Winture

A solar carport is a freestanding canopy structure that combines vehicle shelter with solar panel mounting. Solar panels are installed on the carport roof, generating electricity while the structure below provides shade and weather protection for parked vehicles.
Unlike rooftop solar — which is constrained by roof load capacity, orientation, and structural access — solar carports are purpose-built structures with no constraints from existing building design. This makes them the preferred solar solution for large flat parking areas where the roof is either unavailable, insufficient in area, or structurally unsuitable.
Winture manufactures the complete structural steel package: columns, primary beams, secondary beams, purlins, bracings, and base plates — all from a single factory, with matched production scheduling and consistent dimensional tolerances throughout.
 

Application Scenarios

Commercial Parking Lots & Factory Yards

Wide‑span beam designs (up to 15m clear span) support multi‑row layouts without intermediate columns, preserving vehicle circulation lanes and emergency vehicle access routes. Structural load capacity is engineered for bifacial module weight combined with regional snow load (up to 1.5 kN/m²) and wind load (up to 60 m/s, customizable by site).

Suitable for: shopping malls, logistics parks, manufacturing facilities, EV fleet charging bases, airport ground transport zones.

Residential Communities, Hotels & Office Buildings

Slim‑profile columns (≤150×150mm) minimize visual obstruction while maintaining structural integrity. Optional Powder coated color finishes in standard RAL colors are available to coordinate with building exteriors. Integrated LED lighting conduit routing is pre‑designed into column and beam sections as standard.

Suitable for: apartment complexes, hotel parking areas, office campus lots, hospital staff parking.

EV Charging Integrated Carports

Winture's carport frame includes pre‑designed EV charging infrastructure integration as standard — not as an add‑on. This includes:

• Conduit sleeves through column sections for power cable routing
• Cable tray mounting brackets along primary beams
• Earthing connection points at column base plates
• Structural load distribution designed for simultaneous EV charger operation alongside panel output

This eliminates the retrofit cost and structural interruption of adding EV infrastructure after the carport is erected.

Solar Carport Mounting Structure Configuration

WINTURE supplies single-row, double-row and multi-row solar carport mounting structures for commercial parking lots, industrial facilities and EV charging areas. The appropriate configuration depends on the parking layout, vehicle dimensions, available space and required column positions.

Column Position and Clear Span

Column placement should be reviewed against the actual parking bay dimensions and vehicle movement. A column positioned too close to a parking entrance can restrict turning, while an unsuitable beam height can interfere with taller vehicles.

WINTURE offers solar carport structures with clear spans up to 15 m and column heights from 2.5 m to 5.0 m, subject to the structural configuration and project design requirements. Our engineering team can use the parking layout and vehicle dimensions to review suitable column positions, beam arrangements and steel member sizes.

For a custom layout, provide the parking plan showing bay dimensions, driving aisles, vehicle types and required access routes.

Solar Carport Roof Drainage and Waterproofing

Solar carport mounting structures can provide vehicle shading, but rain protection depends on the roof construction. Standard framed PV modules may leave gaps between panels, allowing rainwater to pass through unless a separate waterproofing arrangement is incorporated.

For projects requiring covered parking with rain protection, the roof design should address the following details:

WINTURE's solar carport structures offer standard roof tilt angles of 5°–15°, with custom angles subject to the project design. Roof drainage requirements should be confirmed together with the mounting geometry and steel support arrangement.

If the project requires a watertight roof, provide the proposed PV module layout, drainage drawings and waterproofing specifications. The required roof accessories, connection details and supply responsibilities can then be clarified before quotation.

Solar Carport Foundation and Column Connections

Solar carport columns must be positioned to support the steel canopy without restricting vehicle access. For new parking developments and existing parking lot retrofits, the column base and foundation details should be confirmed before fabrication.

WINTURE manufactures SHS and H-beam columns, primary beams and base plates. Connection plate dimensions and bolt-hole arrangements can be specified according to approved project drawings.

For Existing Parking Lot Projects

Before confirming column positions, check underground drainage pipes, power cables, utilities and existing pavement conditions. Where columns are close to vehicle circulation areas, allow space for suitable impact protection.

For New Carport Projects

Coordinate the parking layout, steel frame and concrete foundation drawings before producing the columns and base plates. This helps ensure that the fabricated connection details match the approved foundation arrangement.

WINTURE's engineering team uses structural analysis and 3D modeling to support project-specific steel structure design. Customers can submit the carport layout and foundation drawings for review of column arrangements and connection details.

Final foundation dimensions and anchor requirements should follow the approved structural and geotechnical design.
