Design ideas and engineering practice of roof PV mounting system in distributed photovoltaics

The role and functional positioning of the roof PV mounting system
The roof photovoltaic bracket not only serves as the installation platform for photovoltaic modules, but also needs to meet the following core functions:
*Structural fixation: Reliably fix the photovoltaic modules on the roof surface to prevent displacement or falling off caused by external forces such as wind load and snow load;
*Angle adjustment: By reasonably setting the inclination angle and direction, the light receiving efficiency is improved, thereby increasing the power generation;
*Adapt to the roof structure: cope with different roof forms such as concrete, color steel tiles, glazed tiles, etc., to achieve stable connection;
*Anti-seepage and anti-corrosion: Ensure that the roof is not damaged and resist corrosion and oxidation in long-term outdoor environments;
*Easy to install and maintain: The structural design must take into account the efficiency of on-site assembly and the convenience of later operation and maintenance.
Dongsheng New Energy uses the roof PV mounting system as the basic support unit, and designs it from multiple dimensions of structural performance, material technology and use environment, striving to achieve a balance between the safety and economy of the overall system.

System classification design for different roof types
Due to the significant differences in roof structures, the bracket system needs to be classified in scenes at the beginning of the design. Taizhou Dongsheng New Energy has established a bracket solution system for the following typical roof types:
Concrete flat roof bracket system
* Two structures, fixed and adjustable: using cement pier counterweight, expansion bolt fixing or chemical anchor bolt reinforcement;
* Integrated design of base and diagonal beam structure: Enhanced stability;
* Suitable for optimal south-facing inclination: Maximize light utilization.
Color steel tile roof bracket system
* Clamp-type connection solution: Avoid perforating the roof and reduce the risk of water leakage;
* Modular combination of horizontal and vertical beams: Convenient for workers to assemble quickly;
* Lightweight materials: Reduce the load on the roof while taking into account structural safety.

Tile roof PV mounting system
* Hook-type fixing design: Adapt to different tile types such as glazed tiles, small green tiles, etc.;
* Point support method: Protect the original roof structure and improve ventilation capacity;
* Waterproof structural parts matching: Reduce the risk of rainwater penetration.
Each system is customized according to the actual roof structure, geographical location wind pressure, installation density and other conditions to ensure the safety and service life of the project.

Material technology and surface protection design
The roof bracket is exposed to the external environment for a long time, and factors such as wind, rain, ultraviolet rays and pollution can easily cause corrosion and aging. Therefore, the reliability of materials and surface treatment directly affects the life of the system. Dongsheng New Energy adopts the following standards in material selection and process:
*Aluminum alloy bracket (6005-T5): It has the characteristics of high strength, light weight, corrosion resistance, etc., suitable for light load requirements of roofs;
*Hot-dip galvanized steel: Commonly used in industrial roof systems that require higher strength, and the thickness of the galvanized layer meets the national standard anti-corrosion requirements;
*Stainless steel connectors: Used for bolts, hooks, clamps and other parts to ensure stable connection;
*Anodizing treatment/hot-dip galvanizing process: Extend the surface corrosion resistance life, especially suitable for seaside, high humidity and other areas.
All materials of Taizhou Dongsheng New Energy have passed ISO quality system certification, and a strict incoming material inspection and batch control mechanism has been established to ensure product consistency.

How to balance installation efficiency and operation safety in rooftop PV mounting system

Definition and function of roof PV mounting system
The roof PV mounting system is an installation structure that fixes solar cell modules on the roof. Its basic functions include:
*Fixing and supporting function: ensuring the structural stability of photovoltaic modules under natural conditions such as wind load and snow load;
*Angle optimization function: improving light receiving efficiency by adjusting the inclination of modules;
*Structural protection function: reducing the damage of the external environment to the photovoltaic system and ensuring long-term operation;
*Cooperative building adaptability: the bracket design needs to fully consider factors such as the building material, load-bearing capacity and drainage structure.
Dongsheng New Energy's roof bracket system takes into account factors such as structural mechanics, photovoltaic power station efficiency, and on-site construction convenience, and promotes it to form a systematic solution in multiple roof applications.

Bracket system solutions corresponding to different roof types
Roofs are diverse, and different building structures have different design requirements for brackets. Dongsheng New Energy combines roof materials and load requirements to provide the following typical bracket system solutions:

*The fixed structure is mainly used, and expansion bolts are often used for anchoring or counterweight piers for fixing;
*The angle between the bracket and the component is adjustable, which is suitable for the south-facing inclination layout;
*Wind-resistant design considerations, according to the wind load coefficient ratio component array arrangement method;
*Suitable for industrial parks, office buildings and public building roofs, convenient for large-scale installation.
Colored steel tile roof bracket system
*Use special clamps to fit with corrugated tiles to avoid penetrating the roof structure and reduce the risk of water leakage;
*The modular design of beams and longitudinal beams is suitable for tiles of different specifications;
*Suitable for light steel structure buildings such as factories and logistics warehouses, with low requirements for roof load bearing.

Material and structural design points
Roof brackets are exposed to outdoor environments for a long time and must have the basic properties of corrosion resistance, aging resistance and high strength. Dongsheng New Energy adheres to the following principles in material and structural design:
Standard selection standards
Aluminum alloy brackets (such as 6005-T5): suitable for weight-sensitive roofs with strong corrosion resistance;
Hot-dip galvanized carbon steel brackets: suitable for scenes requiring high wind load resistance and high rigidity;
