Detailed analysis of flexible photovoltaic brackets

1. Definition and structure
Definition: Flexible photovoltaic brackets use prestressed flexible cable structures (such as prestressed steel strands) as the main force-bearing components to form a large-span photovoltaic module support system. This bracket structure not only has a large span and clearance height, but also has high flexibility and plasticity.
Structural composition: Flexible photovoltaic brackets are mainly composed of foundations, steel structures and cable bodies, connection accessories, wind-resistant systems and other parts. Structurally, it can be divided into single-layer suspension cable systems, prestressed double-layer cable systems (load-bearing cables + stabilizing cables), prestressed cable nets, hybrid systems and other types.

2. Advantages and characteristics
Strong adaptability: Flexible photovoltaic brackets are not limited to sites and have strong pre-installation. They can be used in a variety of large-span sites such as barren slopes, mountains, ponds, and woodlands. Its installation methods are flexible and diverse, with high space utilization, low usage, small load-bearing capacity, and low cost.
Large-span characteristics: Compared with traditional fixed brackets, flexible photovoltaic brackets have a larger span and can solve installation problems in complex terrain and special projects. For example, in the steep mountainous projects in Yunnan, Guizhou and Sichuan, conventional fixed brackets may not be installed normally, while flexible brackets can adapt well to these terrains.
Convenient installation: The installation process of flexible photovoltaic brackets is simple and quick, and can generally be carried out by simple methods such as pasting and fixing, which greatly shortens the overall construction period.
Cost advantage: By optimizing the structure and the arrangement of steel strands, the investment cost of flexible photovoltaic brackets is lower than that of traditional power stations while reducing the amount of pile foundations.
Versatility: Flexible photovoltaic brackets can not only be used for photovoltaic power generation, but also be combined with industries such as agriculture and fisheries to achieve the composite utilization of land and resources. For example, in the fishery-photovoltaic complementary project, the flexible bracket can generate photovoltaic power without affecting the fishery operation.

3. Application scenarios
The application scenarios of flexible photovoltaic brackets are very wide, including but not limited to:

Photovoltaic power generation projects for public facilities such as sewage treatment plants and parking sheds.
Photovoltaic power generation projects in the agricultural and fishery fields such as agricultural-photovoltaic complementary and fishery-photovoltaic complementary.
Photovoltaic power generation projects in complex terrains and special scenarios such as mountain photovoltaics and building-integrated photovoltaic systems.
Photovoltaic power generation projects for transportation facilities such as highways and streets.
IV. Precautions
Although flexible photovoltaic brackets have many advantages, the following issues still need to be noted during use:

Stability and reliability: Flexible photovoltaic brackets may have safety problems such as tilting and collapse under extreme weather conditions such as strong winds, so their stability and reliability need to be fully considered during the design and installation process.
Maintenance and care: Regularly check and maintain the prestressed cable structure and other components of the flexible photovoltaic bracket to ensure that they are in good working condition.
Topography: Topography factors need to be fully considered during the design and installation process to avoid problems such as component shading and mopping.
