In our daily work, we frequently receive inquiries about "how much does a flexible photovoltaic (PV) bracket cost per watt". However, this question is actually difficult to answer simply, as flexible PV brackets come in a wide range of types and complex models.
Flexible PV brackets can be regarded as the most complex product in the broad category of PV brackets. Compared with fixed brackets, they feature higher technological content and include various types such as single-layer cable (two-cable), double-layer cable (three-cable), single-layer cable net, and double-layer cable net structures.
Each type further derives hundreds of different structural forms due to variations in span, clear height, application scenarios, and geological conditions. This results in the average manufacturing cost per watt of flexible PV brackets ranging from 0.1 yuan to 0.8 yuan.
Furthermore, the market price is also affected by factors such as the manufacturer's reputation and marketing strategies. There is a significant price gap among homogeneous products, and in some cases, products with poor quality may even be sold at a higher price. In the complex environment of the PV bracket market, there is no absolute correlation between price level and product quality.
To gain an in-depth understanding of the cost and price of flexible PV brackets, one needs to have the following knowledge reserves: first, proficiency in the structural technology of flexible brackets; second, familiarity with the characteristics of various materials; and finally, an understanding of processing techniques.
To help you gain a preliminary understanding of the cost overview of flexible PV brackets, the following are reference data on the steel consumption per 1-megawatt (MW) flexible bracket:
-
Single-layer cable (two-cable) structure: It is mostly used in mountainous scenarios. When PHC pipe piles are used as the pile foundation and the spacing span of the pile foundation is generally around 16 meters, the steel consumption per 1 MW is approximately 14 - 19 tons; if a steel column structure is adopted, the steel consumption is about 16 - 24 tons. For a single-layer cable net structure, the steel consumption increases by an average of 2 - 3 tons on this basis.
-
Double-layer cable (three-cable) structure: The foundation of this type of flexible bracket is mostly PHC pipe piles, and the steel consumption per 1 MW is roughly between 15 - 24 tons. In the case of a double-layer cable net structure, the steel consumption per 1 MW needs to be increased by an additional 2 - 3 tons.
-
Special complex scenarios: When flexible brackets are applied in special scenarios such as sewage treatment plants, river channels and ditches, building rooftops, and service area parking lots, and the structure is relatively complex, the steel consumption per 1 MW may reach 40 - 70 tons or more.
It should be emphasized that the above data are only preliminary estimates. The actual steel consumption and cost are comprehensively affected by various factors such as the design input conditions of the flexible bracket, the specific application scenario, and the professional capabilities of the designer. The actual figures may be lower or higher. The content of this article is for reference only and does not represent industry standards or the views of specific enterprises. It is hoped that it can provide some assistance for you in exploring the cost and price of flexible PV brackets.
