[0002] In recent years, with the rapid development of solar power generation, the available land has gradually become less. In addition, in the process of photovoltaic construction, there are generally narrow corners of land that cannot be used, resulting in low actual land utilization. For example, during the construction of fish pond photovoltaics, agricultural photovoltaic complementarity, and tea photovoltaic complementarity, some local locations are narrow and not enough to arrange a set of flexible photovoltaic bracket components, resulting in waste of land on both sides. The size of the flexible bracket component is prepared according to the size of the photovoltaic panel. Since the standard size of the photovoltaic panel is fixed, the size of the flexible bracket component is limited. If the size of the flexible bracket is changed, the standard size of the photovoltaic panel cannot be fixed. Therefore, in order to improve land utilization and effectively utilize the narrow corners of the land, a photovoltaic hybrid bracket structure is needed.
