In photovoltaic agriculture scenarios, tracking support structures can also dynamically adjust their angle according to the light requirements of different crops at different growth stages (such as light-loving crops needing strong light and shade-tolerant crops needing diffused light). This ensures photovoltaic power generation while providing suitable light conditions for the crops below, achieving synergistic optimization of power generation and planting.
