Abstract

This research aims to compare the energy output potential of land-based and floating bifacial photovoltaic (PV) systems of 50 MW and 400 kW with an existing land-based and floating monofacial PV system of the same dimensions and design in Bui, Ghana. The study uses ground weather files and PV system configurations to compare the energy yield from simulations of the different PV systems based on capacity factor, performance ratio, and monthly, final/annual energy yield. The results show that the bifacial gain of land-based and floating bifacial PV systems is 2.51% and 4.57%, respectively, and the capacity factor and performance ratio of the bifacial PV system are higher than the monofacial PV system. However, the additional energy generated by the bifacial PV system is not significant enough to justify the installation of a new system. Therefore, the study recommends optimizing system parameters such as albedo, tilt angle, and ground cover ratio to 0.5, 15°, and 0.3 respectively to enhance the performance and increase the bifacial gain of the PV system. Overall, this study provides valuable insights into the potential of bifacial PV systems in Bui, Ghana, and highlights the importance of optimizing system parameters for maximum energy output.

加纳基于单面和双面组件的地面和浮动太阳能光伏系统性能比较
本研究旨在比较50兆瓦和400千瓦的陆基和浮动双面光伏(PV)系统与加纳Bui现有的相同尺寸和设计的陆基和浮动双面光伏系统的能量输出潜力。该研究使用地面天气文件和光伏系统配置,根据容量系数、性能比、月度、最终/年度能源产量,比较不同光伏系统的模拟发电量。结果表明,陆基和浮式双面光伏系统的双面增益分别为2.51%和4.57%,双面光伏系统的容量因子和性能比均高于单面光伏系统。然而,双面光伏系统产生的额外能量不足以证明安装新系统是合理的。因此,本研究建议将反照率、倾角、地被覆盖比等系统参数分别优化为0.5°、15°和0.3°,以提高光伏系统的性能和双面增益。总的来说,这项研究为加纳Bui双面光伏系统的潜力提供了有价值的见解,并强调了优化系统参数以获得最大能量输出的重要性。
