Environmental conditions have a strong influence on the behavior and quality of the generated photovoltaic (PV) power. The partial sharing condition is a natural phenomenon that reduces the lifetime of the PV array and the effectiveness of the entire system. Dispersing the shadow equally over PV panels is the solution to avoid the negative impact of the partial shading condition. Accordingly, PV array reconfiguration has become an attractive topic of study for researchers. In this paper, the authors provide a comprehensive review of all the schemes proposed for the PV reconfiguration system. In addition, a comparative study among all the published approaches and the challenges facing each approach are presented. Future research topics that highlight new methods to produce higher power from an available PV system are discussed.

环境条件对所产生的光伏（PV）功率的行为和质量有很大影响。部分共享条件是一种自然现象，会缩短PV阵列的寿命并降低整个系统的效率。解决方案是将阴影均匀地分散在PV面板上，以避免局部阴影条件的负面影响。因此，PV阵列的重新配置已成为研究人员的研究热点。在本文中，作者对为PV重构系统提出的所有方案进行了全面回顾。此外，还对所有已发布的方法以及每种方法面临的挑战进行了比较研究。讨论了未来的研究主题，这些主题突出了从可用的光伏系统产生更高功率的新方法。
