Abstract

The optimization of floating bifacial solar panels (FBS PV) in tropical freshwater systems is explored by employing response surface methodology (RSM) and central composite design (CCD). Previous studies have yet to explore the long-term durability, environmental impact, economic viability, and performance of FBS PV systems under various climatic conditions. This study addresses this gap by focusing on panel height, water depth, and tilt angle to improve performance. The quadratic model reveals significant non-linear relationships impacting FBS PV power generation with freshwater cooling. Our models demonstrate high explanatory power, with R-squared values of 0.9831 for output power and 0.9900 for Bi-Facial gain. Experimental validation using conventional white surface (CWS) and proposed freshwater surface (PFS) indicates notable improvements in power generation, achieving a 4.34 to 4.86% gain in bifacial efficiency across various irradiation levels. Under 950 W/m irradiation, freshwater cooling achieves a 3.19% higher bifacial gain compared to CWS cooling. Panel temperature analysis shows consistent reductions with freshwater cooling, ranging from 1.43 to 2.72 °C, enhancing overall efficiency and longevity. This research highlights the potential of freshwater cooling in optimizing bifacial solar systems, offering actionable insights for sustainable energy solutions in tropical regions.

摘要

通过采用响应面法（RSM）和中心复合设计（CCD），探索了热带淡水系统中浮动双面太阳能板（FBS PV）的优化方法。以往的研究尚未探讨FBS PV系统在各种气候条件下的长期耐久性、环境影响、经济可行性和性能。本研究通过关注面板高度、水深和倾斜角度来提高性能，从而填补了这一空白。二次模型揭示了影响FBS PV淡水冷却发电的显著非线性关系。我们的模型具有很高的解释力，输出功率的决定系数R²值为0.9831，双面增益的决定系数R²值为0.9900。使用传统白色表面（CWS）和提议的淡水表面（PFS）进行的实验验证表明，发电量有显著提高，在各种辐照水平下，双面效率提高了4.34%至4.86%。在950 W/m的辐照下，与CWS冷却相比，淡水冷却的双面增益高出3.19%。面板温度分析表明，淡水冷却可使温度持续降低，降幅在1.43至2.72°C之间，提高了整体效率和使用寿命。本研究突出了淡水冷却在优化双面太阳能系统方面的潜力，为热带地区的可持续能源解决方案提供了可操作的见解。
