The core of a solar carport mounting system lies in its support structure, which must not only bear the weight of photovoltaic (PV) modules but also withstand wind, snow, rain, and other environmental loads while ensuring long-term stability and safety. This article focuses on the design, materials, types, and key technical aspects of solar carport mounting structures.
The main roles of a solar carport mounting system include:
Supporting PV modules: Ensuring stable installation of solar panels at optimal tilt angles to maximize power generation efficiency.
Wind and snow resistance: The structure must comply with local climatic conditions to ensure safety during extreme weather.
Providing shade and weather protection: Generating electricity while sheltering vehicles from sun and rain.
Adaptability to different sites: Adjustable in height, span, and layout to meet various parking lot requirements.
The material used significantly impacts durability and cost. Common options include:
Advantages: High strength, cost-effective, strong corrosion resistance (zinc coating prevents rust).
Applications: Suitable for large commercial and industrial solar carports due to high load-bearing capacity.
Advantages: Lightweight, corrosion-resistant, requires no additional anti-rust treatment—ideal for coastal or high-humidity regions.
Disadvantages: Higher cost, slightly lower load-bearing capacity than steel.
Applications: Small to medium-sized carports or weight-sensitive projects.
Advantages: Exceptional corrosion resistance, extremely long lifespan.
Disadvantages: Expensive, typically used only in special environments (e.g., chemical plants or high-salinity areas).
Based on installation methods and design, solar carport mounting structures can be categorized as follows:
Design: Each row of panels is supported by a single column, with PV modules tilted for optimal sunlight exposure.
Advantages: Simple structure, lower cost, suitable for small parking areas.
Disadvantages: Limited span, relatively weaker wind resistance.
Design: Each row is supported by two columns, forming a more stable framework.
Advantages: Higher load-bearing capacity, ideal for windy or snowy regions.
Disadvantages: Occupies more space, slightly higher cost.
Design: Only one side has support columns, with PV modules extending outward, maximizing open space underneath.
Advantages: Aesthetically pleasing, space-efficient, suitable for high-end commercial projects.
Disadvantages: Complex structural design, higher cost.
Design: Multiple carport units connected to form a large-span structure, ideal for expansive parking lots.
Advantages: Material-efficient, structurally integrated, ideal for large-scale installations.
Disadvantages: Complex installation requiring precise load calculations.
Must comply with local wind load standards (e.g., ASCE 7, Eurocode).
Reinforced with diagonal bracing and robust connectors for stability.
Integrated gutters or sloped structures to prevent water accumulation.
Typical tilt angles (5°–15°) balance power generation efficiency and natural water runoff.
Galvanized steel should have a sufficient zinc coating (≥80μm).
Aluminum alloy structures may use anodizing for extra protection.
Prefabricated components for easy transportation and quick assembly.
Adjustable height and span to accommodate different vehicles (cars, SUVs, trucks).
Structures must be grounded to prevent lightning damage.
Cabling should be concealed or routed in waterproof conduits.
Foundation Work: Concrete footings or anchor bolts to secure columns.
Column Installation: Ensure vertical alignment using a level.
Beam and Purlin Assembly: Connect primary and secondary beams to form the support frame.
PV Module Installation: Secure solar panels using clamps or rails.
Electrical Integration: Wiring, inverter installation, and grid connection testing.
Lightweight Designs: High-strength aluminum alloys or composite materials to reduce weight.
Smart Tracking Mounts: Auto-adjusting angles to follow the sun (tracking carports).
Building-Integrated Photovoltaics (BIPV): Seamless integration with architectural structures for enhanced aesthetics.
The mounting structure is the backbone of a solar carport system, directly impacting safety, efficiency, and longevity. Selecting the right material (galvanized steel or aluminum alloy), structural type (single-column, double-column, or cantilever), and optimizing wind resistance and drainage are critical for project success. With advancing technology, future mounting systems will become lighter, smarter, and more efficient, further driving the adoption of solar carports worldwide.
