[0002] With the rapid development of photovoltaic power generation, flexible support structures, a relatively land-saving solution, are being used more and more frequently. As flexible support technology matures, photovoltaic power generation projects such as fish-solar hybrid projects and those in mountainous areas often adopt a combination of flexible and fixed support structures. To better conserve land resources, flexible support structures are typically used on larger, relatively flat plots, while fixed support structures are placed in the remaining corners and edges. Flexible support structures require inclined tie rods to prevent tilting. The presence of these tie rods leads to significant land waste at the junction of flexible and fixed support structures. This increases project costs to some extent and may prevent timely completion.
