Structural logic and application practice of carport pv mounting system

Basic structural composition of carport pv mounting system
The carport pv mounting system is mainly composed of steel structure frame, pv module mounting mounting, foundation structure, drainage system, fastening connectors and other parts. According to the structural method, it can be divided into single slope, double slope, inverted T type, Y type, flat top type and other forms, usually customized according to factors such as site size, vehicle layout, lighting requirements, etc.
The support system must not only have the function of carrying pv components, but also meet the requirements of wind load, snow load and vehicle traffic, and have certain technical standards for the safety, durability and drainage capacity of the structure.

Functional integration: the core advantage of the carport support system
1. Compatible with power generation and shading needs
The carport pv mounting system integrates pv components on the top of the carport, so that the original single shading facility has the function of power generation, saving land resources and improving the economic benefits per unit area. For areas with tight urban land use, it is particularly suitable for the construction of green energy supporting facilities in large parking lots or commercial places.
2. Enhance the added value of buildings
The carport mounting system can be combined with charging piles and battery energy storage systems to build an "integrated pv storage and charging" platform, which is suitable for new energy vehicle charging scenarios and is also convenient for local energy consumption and management.

Key points and adaptability of structural design
Taizhou Dongsheng New Energy Power Engineering Co., Ltd. fully considers the following aspects in the design of the carport mounting to improve the applicability and safety of the system:
1. Structural stability analysis
The mounting structure needs to calculate the load based on data such as wind speed, snow thickness, and earthquake level at the project site. During the design process, the company widely uses structural analysis software for three-dimensional modeling and force simulation to ensure that the system can operate stably for a long time.
2. Material selection and anti-corrosion treatment
The main structure is mostly made of hot-dip galvanized carbon steel or aluminum-magnesium-zinc alloy steel, which has strong corrosion resistance. In coastal or high-humidity areas, surface passivation, spraying or stainless steel components are also used to enhance the service life.
3. Drainage and snow removal design
The top of the carport is usually designed with a certain inclination angle to facilitate the natural discharge of rainwater and snow. Some structures will also integrate drainage troughs and drainage pipe systems to prevent rainwater from dripping directly and causing water accumulation on the ground.

Customized application solutions in different scenarios
1. Commercial building parking lot
It is suitable for modular assembly structure, quick installation, and improved on-site construction efficiency. It can be integrated with intelligent lighting, advertising system, guide system, etc. to enhance the additional functions of commercial space.
2. Industrial park carport
The structure is mostly large-span Y-type or inverted T-type, with stronger bearing capacity, which can meet the parking needs of employee commuting vehicles and trucks. The pv system can be connected to the factory power system on site to reduce electricity costs.
3. Residential area or hospital carport
It is usually designed as a double slope or flat roof, with a simple structure, beautiful and coordinated appearance, focusing on safety and shading effect. It is often combined with the community green power management system to support indirect power supply of electric vehicles.

Construction method and operation and maintenance system
1. Factory prefabrication and on-site assembly
In order to improve construction efficiency and product consistency, the company promotes prefabricated construction methods. The main structure is cut, drilled and surface treated in the factory, and then transported to the site for modular assembly to reduce on-site welding and secondary processing time.
2. Installation guidance and quality control
Taizhou Dongsheng New Energy Power Engineering Co., Ltd. provides customers with on-site installation guidance services to ensure that the mounting is laid out in a standardized manner and the pv components are arranged reasonably. After installation, structural inspection and system debugging are carried out, and the reliability of the project is improved through a third-party acceptance mechanism.
3. Post-operation and maintenance support
The operation and maintenance of the carport pv mounting system focuses on structural stability inspection, anti-corrosion coating repair, fastener maintenance, and dust cleaning. The company provides regular inspection and maintenance plans to help users maintain stable operation of the system.

Build a green travel and energy synergy scenario
Driven by the "dual carbon" goal, the carport pv mounting system is developing towards an "energy + transportation" fusion model. Linking the pv system with energy storage equipment, electric vehicle charging piles, and energy consumption management systems can achieve the following synergy scenarios:
* pv power generation directly supplies energy to new energy vehicles during the day;
* Use energy storage equipment to peak power supply in the evening;
* Establish a green travel recharge station to serve the city's low-carbon transportation system.
In the future, the carport pv system will not only be a combined carrier of parking and power generation, but also a basic node for realizing the integration of multi-scenario functions.

Integrated application and development trend of multifunctional carport PV mounting system

Dual value positioning of carport pvs
The carport pv mounting system is a structural system that integrates pv power generation and vehicle shading functions, and is usually installed in parking lots, residential areas, commercial plazas or industrial parks. It not only provides vehicles with shading, rain shelter, and slowing aging functions, but also realizes the on-site conversion and utilization of solar power through pv modules. This type of system is an important branch of distributed pv systems, and is often promoted simultaneously with urban energy planning and transportation infrastructure upgrades. While achieving functional integration, the carport pv mounting has put forward multi-dimensional design requirements for structural strength, bearing performance, spatial layout, drainage capacity and installation convenience.

Common structural forms and material selection
The carport pv mounting structure is often divided into single slope, double slope, cantilever and column symmetrical types. The specific form is determined according to the size of the site, the direction of vehicle traffic, the lighting conditions and the drainage layout.
*Single slope: suitable for wall arrangement or limited space area, simple shape and flexible installation angle.
*Double slope: symmetrical shape, main beam set in the middle of the mounting, relatively balanced structure, suitable for large parking lots.
*Cantilever type: The columns are arranged on one or both sides, and the beams are extended to form a sheltered area, which reduces the obstruction of parking spaces and improves the utilization rate.
In terms of materials, commonly used ones include hot-dip galvanized steel, aluminum alloy profiles and aluminum-magnesium-zinc alloy. Hot-dip galvanized steel has good corrosion resistance and high strength, and is suitable for areas with heavy wind and snow loads; aluminum alloy is used in projects with high visual and aesthetic requirements due to its light weight and neat appearance.

PV module layout and mounting connection method
In the carport mounting system, pv modules are usually installed on the top of the mounting in a horizontal or vertical layout. The layout method should optimize the inclination angle according to the on-site solar radiation angle, generally between 10° and 25°, to improve the average annual power generation efficiency.
In terms of connection method, the rail clip-on module installation system can be used for rapid deployment and maintenance; some projects also combine block-type and clamp-type connection methods to adapt to different module frames and load distribution characteristics. The layout of the top module of the carport should consider the design of the drainage channel to avoid water accumulation and leakage.

Foundation form and ground adaptation strategy
The foundation form of the mounting system varies depending on the site soil, load-bearing requirements and construction period. Common foundation methods include:
* Precast concrete foundation: used in areas with stable geology and a relatively wide construction period.
* Expansion bolt-type anchor foundation: suitable for built hard ground (such as concrete floor, paving brick surface).
* Screw pile foundation: suitable for some soft ground or removable application scenarios.
Taizhou Dongsheng New Energy Technology Co., Ltd. provides flexible adaptation solutions in foundation design, which can adjust the foundation type and depth according to different terrain differences to ensure overall stability and service life.

Key points of structural load design of carport pv system
The carport pv system needs to fully consider the combined effects of wind load, snow load and seismic load, especially in areas with high altitudes or drastic seasonal climate changes. In conventional design:
* Wind load is calculated according to the local annual maximum wind speed to ensure that the wind resistance level of the structure meets the standard;
* Snow load is analyzed by simulating the uniformly distributed load under the snow state to analyze the main beam, auxiliary beam and connection nodes;
* Earthquake load focuses on the overall rigidity and the seismic resistance of the connection nodes, and expansion joints and shock absorption devices are configured when necessary.
Dongsheng New Energy Technology Team uses finite element simulation analysis tools to evaluate the stability of the system in advance and verify the structural reliability through actual tests.

Electrical connection and energy utilization of carport pv system
The carport pv mounting system is the structural basis of the pv power station. The upper pv components are connected in series and parallel to form an array. After connecting to the inverter, they output AC power, which can be directly connected to the park power grid, used for charging pile power supply, or grid-connected power generation.
Common electrical configurations also include:
* The DC combiner box is arranged on one side of the carport for centralized wiring;
* The inverter is installed on the column or independent platform behind the mounting;
* The system reserves cable troughs or pipes to avoid cable exposure and improve safety and cleanliness.
Taizhou Dongsheng New Energy Technology Co., Ltd. can provide complete solutions from wiring diagram design, equipment selection to protective installation in terms of system integration.

Operation and maintenance management and long-term economic benefit analysis
The operation and maintenance of the carport pv system is more convenient than that of ordinary roof systems because the mounting is of moderate height, which is convenient for maintenance and cleaning. Regular inspection of mounting fasteners, inverter status and power generation data is the core link to ensure stable operation of the system.
From the perspective of economic benefits, the carport pv mounting system has the following characteristics:
*The initial investment can be recovered through multiple channels such as carbon trading, electricity cost savings, and green building certification;
*The mounting body has a structural durability of more than 10 years, and the life of pv modules is usually more than 25 years;
*After the integration of auxiliary facilities such as charging piles, an integrated green energy ecology of "pv + energy storage + travel" can be formed.

Future development trends and technology upgrade directions
As the construction of urban green infrastructure advances, the carport pv mounting system will evolve in the following directions:
*Combined with smart microgrids to improve the self-generation and self-use rate;
*Modular mounting design to achieve rapid installation and disassembly;
*Introducing BIPV (building integrated pv) components to improve the integrity of the building;
*Configuring intelligent operation and maintenance systems to achieve remote monitoring and early warning maintenance.
Dongsheng New Energy is actively planning the functional integration of carport pv systems and expanding the extension possibilities in application scenarios such as transportation hubs, logistics centers, and industrial parks.
