They can be positioned for optimal sun exposure, avoid roof structural limitations, and provide easy access for maintenance. However, their success depends entirely on proper foundation design and installation. When designing flexible photovoltaic supports, the requirements of structural stability, weather resistance, lightweight and strength must be comprehensively considered to ensure the long-term reliability of the supports in different climate conditions. The invention relates to the technical field of brackets, and provides a flexible photovoltaic bracket suitable for complex terrains, which comprises steel upright posts, wherein a plurality of groups of steel upright posts are arranged, the number of each group of steel upright posts is two, the. In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed. What is a flexible PV support. Featuring a distinctive support structure, aluminum alloy tracks, and Z-shaped clamping components, our bracket system is designed with CZT's signature characteristics. Pre-installed brackets reduce labor and installation time, making the process quick and efficient. Therefore, flexible PV mounting systems have been developed.
