The flexible photovoltaic support beam is an essential part of the flexible photovoltaic support system.

Flexible photovoltaic support refers to a prestressed structural system formed with cables as the main load-bearing components. Its primary materials are steel and cables, and it can be categorized into the following two types based on structural form:

- Flexible systems such as single-layer cable-suspended structures primarily composed of flexible cables.
- Semi-rigid systems such as cable-truss structures and tensegrity structures formed by combining rigid components with flexible cables.

Compared to traditional photovoltaic supports, flexible photovoltaic supports offer better crack resistance, reduced steel usage, lower load-bearing requirements, lower cost, minimal site foundation demands, and strong pre-assembly capabilities, significantly shortening the construction cycle. Additionally, their large span and flexible operation enable maximum land space utilization, ensuring excellent ventilation, high power generation efficiency, and strong wind resistance.

Flexible photovoltaic supports can reduce construction costs to some extent on complex terrains and are applicable in various large-span environments such as agricultural-photovoltaic互補(bǔ), fishery-photovoltaic互補(bǔ), mountainous photovoltaic installations, and sewage treatment plants, without affecting crop cultivation or fish farming.
