Product Description
The carbon steel solar cantilever carport is a building-integrated photovoltaic (BIPV) product that deeply integrates photovoltaic power generation with parking functionality. Its core structure uses high-strength carbon steel as the main frame, paired with aluminum alloy rails and a waterproof system, combining structural stability, power generation efficiency, and space utilization as its three core values. Compared to traditional carports, this product not only provides vehicles with sun and rain protection but also converts solar radiation into clean electricity using solar panels on the roof, achieving a "two-in-one" function.
The cantilever structure is the most prominent design feature of this product—an optimized column layout achieves a "pillar-free" design, providing an unobstructed passage experience for vehicle entry, exit, and parking. The overall design is simple and modern, suitable for diverse scenarios ranging from private family parking spaces to large public parking lots, and offers flexible options such as single-column bidirectional and double-column unidirectional structures.
Product Components
Advantage
▶ Maximized Space Utilization – Column-Free Parking Experience
The biggest advantage of the cantilever design is the elimination of the front pillar, creating an unobstructed parking space. Vehicles can enter and exit without having to avoid pillars, significantly reducing the risk of scratches and collisions, making it especially suitable for large vehicles and drivers with mobility impairments. The pillar foundation occupies a very small area; some products require only 70×50cm of space, making vehicle parking more convenient.
▶ Combining Structural Strength and Durability
Using high-quality Q235B carbon structural steel and other materials, the cantilever carports undergo hot-dip galvanizing for corrosion protection and have passed salt spray testing. Taking a commercial cantilever carport as an example, it can withstand wind loads of 60 m/s and snow loads of 1.4 kN/m², making it suitable for typhoon-prone areas and heavy snowfall climates, ensuring safe and reliable long-term outdoor use. The core carbon steel structure is designed for a service life of up to 25 years, and manufacturers generally offer a 10-year warranty.
▶ Customizable and Rapid Assembly
The product adopts a modular design, with extensive pre-assembly completed before shipment. On-site installation requires no cutting or drilling, only bolt connections, significantly shortening the construction cycle. It can also flexibly adapt to customers' customized needs in terms of different spans, parking space numbers, and structural forms, meeting the "one plan, one design" project requirements.
▶ Dual Economic and Environmental Benefits
The comprehensive cost per square meter of a photovoltaic carport is approximately 1,000 yuan, only 300-400 yuan more than a conventional membrane structure carport. However, the cost can be quickly recovered through national and local electricity subsidies. The photovoltaic system can generate electricity sustainably for 25 years, and after recovering the initial investment, a net return of -20% can be enjoyed. For example, a 1.6MWp cantilever carport project in Malaysia generates an average of 1.9 million kWh of electricity annually, meeting 15% of the factory's operational electricity needs.
▶ Enhanced Vehicle Protection and Integrated Charging
Solar carports not only block direct sunlight, solving the problem of high temperatures inside vehicles in open-air parking lots during summer, but also provide a natural on-board charging location for electric vehicle owners. The system can integrate charging piles to achieve a three-in-one system of "parking + charging + power generation".

Important Notes:
▶ Confirm Site Foundation Conditions
The ground must be flat and firm to avoid uneven settlement that could lead to structural deformation.
Inspect underground pipelines (cables, water pipes, gas pipes, etc.) in advance to avoid construction damage.
Consider drainage direction to ensure smooth connection between the carport's drainage channels and the site's drainage system.
▶ Strictly Calculate Wind and Snow Loads
Although aluminum alloy has high strength, different cross-sections and connection methods result in varying load-bearing capacities. Calculations or test reports from the manufacturer should be requested based on local 50-year return period wind and snow pressure.
In coastal typhoon areas, it is recommended to use a reinforced support structure and add diagonal bracing.
▶ Pay Attention to Waterproofing Details
The effectiveness of structural waterproofing depends on processing precision and installation quality. Leaks may occur after the sealant or sealing strips at joints age. A clear waterproofing warranty period (e.g., 5-10 years) should be specified.
For large-span carports, a water spray test is recommended to confirm the absence of leaks.
Summary
Carbon steel solar cantilever carports are a mature product in the field of "photovoltaics + building" integration, combining practicality, economy, and environmental value. Using high-strength carbon steel as its framework and a cantilever structure as its highlight, it achieves unobstructed passage without pillars and a highly flexible spatial layout; simultaneously, it integrates photovoltaic power generation, generating clean energy benefits for 25 years.
From private family parking spaces to large commercial parking lots, from industrial parks to public institutions, this product can provide customized solutions to meet the different needs of various scenarios regarding power generation efficiency, vehicle protection, and spatial aesthetics. Although the initial investment is higher than traditional carports, its short payback period and significant long-term returns are due to electricity cost savings, surplus electricity revenue from grid connection, and policy subsidies.
With the continued advancement of the dual-carbon strategy and the rapid popularization of new energy vehicles, carbon steel solar cantilever carports are not only a green upgrade for parking spaces but also an important infrastructure for achieving low-carbon transformation and enhancing asset value.
