Photovoltaic (PV) power plants have shown rapid development in the renewable sector, but the research areas have mainly included land installations, and the study of fishery complementary photovoltaic (FPV) power plants has been comparatively less. Moreover, the mechanism of local microclimate changes caused by FPV panels has not been reported. This work revealed this mechanism using a physical model to illustrate the impact of FPV power plants in a lake on the environment. The results indicated that the lake becomes a heat sink after deploying the PV panel on water. The comprehensive albedo (0.082) decreased by 18.8% relative to the free water surface (0.101). The water energy change was dominated by the water-air vapor pressure deficit. In addition, the FPV panels had a heating effect on the ambient environment; however, the range of this effect was related to the water depth. The installation had an obvious heating effect on surface water.
光伏（PV）发电厂在可再生能源领域发展迅速，但研究领域主要集中在陆地上的设施，而对渔业互补光伏（FPV）发电厂的研究则相对较少。此外，FPV 面板引起的局部小气候变化的机制尚未有报道。本工作使用物理模型来阐明在湖泊中部署 FPV 发电厂对环境的影响，从而揭示了这一机制。结果表明，在水面上部署光伏板后，湖泊变成了一个热汇。综合反照率（0.082）相对于自由水面（0.101）降低了 18.8%。水能量变化主要由水-空气蒸气压差决定。此外，FPV 面板对周围环境有加热作用，但这种作用的范围与水深有关。该设施对地表水有明显的加热效果。
