The Floating Solar Photovoltaic System (FSPV) is emerging as a favorable technology to policymakers for economically harvesting renewable energy. The implementation of large-scale photovoltaic (PV) systems is often disrupted due to the unavailability of land. The FSPV systems, where the PV modules are floated in water bodies facilitate optimal utilization of water resources and land assets. The FSPV provides higher power output compared to land-based PV systems of the equal area because of improved energy conversion efficiency at a lower temperature. Another opportunity for the FSPV system is integration with hydropower stations, storage systems, and the electric grid. This paper explores the flood duration curve-based optimal sizing of the FSPV System with the objective of electrification of rural micro-grid. A comparison of energy output and module temperature rise has been made for the FSPV system and its equivalent land-based PV system of equal area. The system generates 18.08 GWh, which is 10.04% more than the land-based PV system. The DC Capacity factor is 17.2%. The Demand Supply Factor () for a particular day in winter, spring, summer, and monsoon is 37.55%, 41.7%, 45.9%, and 25% respectively. The results indicate that the FSPV system is a sustainable alternative to power renewable energy-based mini micro-grid and provide cost effective electricity to all.
漂浮式太阳能光伏系统（FSPV）正成为政策制定者青睐的一种技术，可经济地获取可再生能源。由于土地资源有限，大规模光伏（PV）系统的实施常常受到干扰。FSPV系统将光伏组件漂浮在水体上，有利于水资源和土地资产的优化利用。与同等面积的陆基光伏系统相比，FSPV系统在较低温度下能量转换效率更高，因此能提供更高的功率输出。FSPV系统的另一个机遇是与水电站、储能系统和电网集成。本文以农村微电网电气化为目标，探讨基于洪水历时曲线的FSPV系统优化规模。对FSPV系统及其同等面积的等效陆基光伏系统的能量输出和组件温度上升进行了比较。该系统发电量为18.08吉瓦时，比陆基光伏系统多10.04%。直流容量系数为17.2%。冬季、春季、夏季和季风季节某一天的需求供应系数（）分别为37.55%、41.7%、45.9%和25%。结果表明，FSPV系统是为基于可再生能源的微型微电网供电的可持续替代方案，可为所有人提供具有成本效益的电力。
