Solar Carports
Solar carports are becoming more relevant in New Zealand, especially for commercial sites, storage facilities, schools, and logistics yards.
Generate Energy from Your Parking Areas
A solar carport is a purpose-built canopy structure with solar panels installed on the roof of the parking shelter rather than on a building.
It works in the same way as a rooftop solar system, generating electricity on-site while also providing protection for vehicles parked underneath.
Solar carports allow businesses to turn open parking areas into productive energy spaces. Instead of leaving large outdoor areas unused, organisations can generate renewable electricity during the day when demand is often highest. This can help reduce grid power use, lower operating costs, and support long-term energy planning

Solar Carports Installation Process
At Trilect Solar, we employ a three-stage process for solar carports. This careful, step-by-step process ensures that we only install the most efficient, safe, and durable solar carports for our clients.
- Feasibility assessment
The first step is to confirm whether a solar carport is suitable for your site. This is particularly useful where roof space is limited or where businesses want to make better use of existing parking areas. - System sizing and design
The system is designed based on your site’s energy use and parking layout. Depending on project goals, this may focus on offsetting electricity demand, maximising solar coverage across the car park, or allowing for future expansion. - Geotechnical study and structural planning
Ground conditions are assessed to inform foundation design and structural requirements, ensuring the carport is safe, compliant, and suited to the site environment. - Electrical design
Electrical design includes cable sizing, system layout, and solar string configuration to support safe installation and efficient long-term performance.
- Structural steel fabrication Once structural drawings are completed, a steel fabricator prepares shop drawings based on the engineering design. After approval, fabrication begins. This stage typically takes one to three weeks depending on the size and complexity of the project.
- Galvanising and delivery After fabrication, the steel components are galvanised to protect against corrosion and support long-term durability. The finished materials are then delivered to site, ready for installation.
- Foundations and footings Installation begins with preparing the foundations. This may involve cutting into existing concrete or asphalt surfaces, or preparing new ground areas depending on the site layout. Footing design is based on soil conditions, terrain, and structural requirements.
- Steel erection Structural columns and rafters are installed first, followed by purlins that support the solar panels. Alignment and structural accuracy are checked throughout this stage to ensure a safe installation.
- Panel installation and wiring Solar panels are installed once the structure is complete, followed by electrical wiring within the structure and connections to the inverter systems. Cabling is typically routed through underground conduits where required.
- Testing and commissioning After installation, the system undergoes electrical testing including insulation resistance, voltage, and performance checks. The project is then commissioned and prepared for handover.
frequently asked questions
Here are some common questions businesses ask when considering solar carports installation, including design requirements, approvals, and site planning considerations.
What is a solar carport?
A solar carport is a purpose-built structure that provides vehicle shelter while generating electricity using solar panels installed on the canopy above parking spaces.
Unlike rooftop solar systems, solar carports make use of existing parking areas to produce renewable energy without relying on available roof space. They can be installed over existing car parks, in open parking areas, or integrated into larger site layouts depending on project requirements.
What are the benefits of solar carports for businesses?
Solar carports offer both energy and site usability benefits.
Dual-purpose functionality
They provide vehicle protection from sun and rain while generating renewable electricity on-site. Solar carports can also support EV charging infrastructure.
Reduced reliance on grid electricity
Generating solar energy during the day helps offset power use and reduce exposure to rising electricity costs.
Visible sustainability investment
Solar carports demonstrate a practical commitment to renewable energy and support wider sustainability targets.
Future-ready infrastructure
Systems can be designed to allow for battery storage integration or additional EV charging capacity as site needs grow.
Demand for solar carports in New Zealand increased significantly in 2024, with imports rising sharply compared with the previous year. This reflects growing interest from commercial sites looking to improve energy resilience and make better use of existing parking areas.
Do solar carports reduce the number of available parking spaces?
No. Solar carports are typically designed to be installed over existing parking bays without reducing parking capacity or affecting normal vehicle access.
Can solar carports be installed over existing car parks?
Yes. Solar carports are commonly installed over existing parking areas with minimal disruption to site operations. Installation planning ensures traffic flow and access remain functional during construction.
Can solar carports be customised for different sites?
Yes. Solar carport structures can be designed to suit different parking layouts, ground conditions, and operational requirements. Systems can also support different panel configurations and future expansion if needed.
Can solar carports support EV charging infrastructure?
Yes. Solar carports are well suited for EV charger integration. Planning for charging infrastructure during the design stage helps improve installation efficiency and supports future fleet or staff charging requirements.
Can solar carports support additional site features?
Solar carports can be designed to accommodate additional infrastructure such as lighting, security systems, and other site services depending on project requirements.
Do solar carports require building consent in New Zealand?
Yes, solar carports typically require building consent because they are standalone structures with foundations. Structural engineering documentation is usually needed to confirm compliance with the New Zealand Building Code.
Consent requirements depend on factors such as structure size, height, wind zone classification, and site conditions. Early design coordination helps streamline this process.
Are wind zones important when designing a solar carport?
Yes. Wind zone classification is a key factor in solar carport design across New Zealand.
Because solar carports are elevated structures, they must be engineered to suit site-specific wind loading. This affects structural sizing, foundation design, and overall system configuration. Engineering is normally completed early in the project to ensure compliance and performance.
Do seismic requirements affect solar carport installation?
Yes. Like other structural elements on commercial sites, solar carports must meet New Zealand seismic design requirements.
Engineering design considers ground conditions and seismic loading to ensure the structure performs safely over its service life.
How are solar carports connected to the power grid?
Solar carports connect to your site’s existing electrical infrastructure in a similar way to rooftop solar systems.
Grid connection requirements depend on system size and site capacity. Larger commercial systems may require approval from the local network operator. Early electrical assessment helps confirm connection options and export capability if applicable.
