光伏（PV）发电系统通常配有电池，以弥补发电和负载需求之间的差距。太阳跟踪还用于增强功率稳定性并增加从太阳收集的能量。然而，电池和跟踪设备显着增加了系统成本，并且它们容易磨损，这使得免维护安装具有挑战性。在这项工作中，我们对太阳能系统的双三维光伏电池板进行了设计优化。通过所提出的三维布置，我们延长了仅由太阳能供电的目标应用的太阳能供电时间。实验结果表明，与相同光伏板面积的不可重构平板相比，所提出的架构和控制方法将目标系统的服务时间延长了高达 23%。
Photovoltaic (PV) power generation systems are usually accompanied by battery to bridge the gap between the generation and load demand. Solar tracking is also used to enhance the power stability and increase the amount of collected energy from the Sun. However, battery and tracking devices significantly increase the system cost, and they are subject to wear and tear, which makes maintenance-free installation challenging. In this work, we conduct the design optimization of a twofold three dimensional PV panel for solar-powered systems. With the proposed three dimensional arrangement, we extend the solar-powered time of the target application that is powered only with solar power. Experimental results show that the proposed architecture and control method extend the service time of the target system by up to 23% compared to a non-reconfigurable flat panel with the same PV panel area.
