To meet the required load of a farm in the rural area in Mafraq, Jordan, the complete floating photovoltaic (FPV) water pumping sizing, modelling, and optimization of an on-grid PV system with comprehensive capacity, energy output cost, and emission estimations are outlined in this work. The novelty of this study lies in its comprehensive approach that integrates technical, environmental, and economic factors into a unified framework for designing a PV water pumping system, particularly in scenarios where grid supply is feasible or economically viable. A proposal has been made to install PV panels over the water lake to improve the overall system efficiency and to give an aesthetic appearance. The proposed system is composed of a 165 kW PV array and three 55 kW inverters, which cost 54696.92 JD as the initial cost, CO emission reduction of more than 5000 tons and produce electricity at 0.028 JD/kWh. The results indicated that the FPV option demonstrates an about 5 % increase in efficiency compared to the other two scenarios. Also, the FPV option has higher costs due to a 25 % increase in system cost but results in lower CO emissions compared to the other two options. Top of Form As shown from the results, the two sizing methods for solar water pumping systems, the equations-based method, and the PVsyst simulation tool give the same results. By following this methodology, one can assess the load, size the system, simulate its operation, and analyse the expected performance. Furthermore, the findings of this study could be valuable in designing a grid-connected FPV water pumping system.
为满足约旦马弗拉克农村地区某农场的所需负荷，本文概述了完整的浮动式光伏（FPV）抽水系统的选型、建模以及对具有综合容量、能量输出成本和排放估算的并网光伏系统的优化。本研究的新颖之处在于其采用综合方法，将技术、环境和经济因素整合到一个统一框架中，用于设计光伏抽水系统，特别是在电网供电可行或经济可行的情况下。已提出在水湖上安装光伏板，以提高整个系统效率并提升美观度。拟议系统由一个165千瓦的光伏阵列和三个55千瓦的逆变器组成，初始成本为54696.92约旦第纳尔，减少二氧化碳排放量超过5000吨，发电成本为0.028约旦第纳尔/千瓦时。结果表明，与其他两种方案相比，FPV方案的效率提高了约5%。此外，FPV方案由于系统成本增加25%而成本更高，但与其他两种方案相比，其二氧化碳排放量更低。结果表明，太阳能抽水系统的两种选型方法，即基于方程的方法和PVsyst模拟工具给出了相同的结果。按照这种方法，人们可以评估负荷、确定系统规模、模拟其运行并分析预期性能。此外，本研究结果对于设计并网FPV抽水系统可能具有重要价值。
