The scope for water-based photovoltaic (WPV) installations has raised questions related to its performance in comparison to traditional land-based photovoltaic (LPV) installations. In literature, few studies exist, and they mainly highlighted the performance of WPV and LPV based on energy analysis but fails to give a detailed understanding. In this paper, the exergy based parametric approach is used to understand the realistic performance and the energy conversion process of the photovoltaic (PV) module in both water and land environments. Three amorphous silicon thin-film PV modules installed in ground-mount PV (GMPV), floating PV (FPV), and submerged PV (SPV) methods are considered for experimentation to understand the exergy performance. The experimental results show that the exergy efficiency is varied for each installation method. It is observed that the exergy efficiency of SPV is 3.07% higher than the FPV and 43.65% higher than GMPV installation methods, respectively. Overall, the thermodynamic analysis of the thin-film PV module provided in this study delivered a critical understanding of the performance, and this study will serve as a useful reference in selecting the best installation methods.

与传统的陆基光伏（LPV）装置相比，水基光伏（WPV）装置的范围引发了与其性能相关的问题。在文献中，很少有研究，它们主要基于能量分析强调了WPV和LPV的性能，但没有给出详细的了解。在本文中，基于火用的参数方法用于了解水和陆地环境中光伏（PV）模块的实际性能和能量转换过程。实验中考虑了三种安装在地面安装式PV（GMPV），浮动式PV（FPV）和潜水式PV（SPV）方法中的非晶硅薄膜PV模块进行实验，以了解火用性能。实验结果表明，每种安装方法的火用效率都不同。可以看出，SPV的火用效率分别比FPV高3.07％和比GMPV安装方法高43.65％。总体而言，本研究提供的薄膜光伏组件的热力学分析对性能提供了重要的了解，该研究将为选择最佳安装方法提供有用的参考。
