Flexible photovoltaic bracket system

In recent years, there have been more and more photovoltaic application scenarios, and the proportion of composite or integrated applications of photovoltaics with different business types and environmental management is increasing. The industry's requirements for photovoltaic brackets and environmental suitability will also become higher and higher. For rigid fixed supports, due to their limitations in pile foundation density, row spacing and clearance, in some scenarios, they can no longer fully meet various needs, especially in land composite and efficient utilization.

In recent years, photovoltaic flexible brackets have effectively solved the adaptability and economic problems of brackets in certain scenarios by virtue of their structural characteristics of "large span, high clearance, and long row spacing". The flexible photovoltaic support is a large-span, multi-span structure that tensions prestressed steel wire ropes between fixed points at both ends. The fixed points use a rigid structure and outer cable-stayed steel strands to provide support reaction force. It can achieve large spans of 10~30m and adapt to situations such as undulating mountains and increased vegetation. It only needs to set the foundation at the appropriate location and tension the prestressed steel strands or wire ropes.

The construction of rigid columns, foundations and flexible supports can be realized in lakes and fish ponds while the water level remains constant.

Because flexible brackets have the advantages of large spans and flexible and adjustable span ranges, they have a wider range of applications, including:

(1) It is suitable for areas with mountainous slopes and large undulations. It is not affected by factors such as the height of vegetation. The height of the lower edge of the module from the ground can be adjusted within 1m~7m, which is suitable for using longer single-row array lengths (row spacing). ). In current actual projects, the longest single-row array length reaches 1,500m.

(2) It is suitable for fishing ponds, tidal flats and other areas. It breaks through the limitations of traditional supports such as water depth, area size and other conditions. Through the advantages of the large-span solution of 10 to 30 m of flexible supports, as well as other solutions such as additional support columns that can be installed in the middle, it solves the problem of fishing It is difficult to construct and install traditional supports in ponds, tidal flats and other areas;

(3) It is suitable for the top of the sewage plant pool. Due to the requirements of the sewage plant water treatment process, it is impossible to install a bracket foundation inside the large-volume pool. The flexible bracket can cleverly avoid this difficulty, making it possible to build a photovoltaic power station in the sewage plant pool.

System advantages

(1) Application scenarios that combine photovoltaics with agriculture and fishery can avoid or reduce the impact on breeding operations. The flexible bracket adopts a large-span, high-clearance structural design, which is more suitable for photovoltaic application scenarios that are combined with agriculture and fishery. It can Truly achieve "both are suitable, both are correct".

(2) In some scenarios, it can reduce the damage or impact on vegetation, which is beneficial to the reduction of the number of water and soil conservation foundations and the amount of earthwork construction. It can reduce the damage or impact on vegetation, which is beneficial to water and soil conservation, especially for water and soil conservation requirements. , an area with a relatively fragile environment.

(3) It is conducive to improving the power generation efficiency of the system, including the gain level of double-sided power generation. The structural features of high clearance and large span are beneficial to the ventilation and heat dissipation of the photovoltaic array, reducing the operating temperature of the components, thereby reducing the temperature loss of the maximum power of the components.
