Techno-Economic Analysis of Floating Solar FPV: Case Studies and Comparative Studies


Floating solar photovoltaic (FPV) systems have gained significant attention as a promising technology for harnessing solar energy. As the demand for renewable energy grows, it becomes imperative to conduct techno-economic analyses to evaluate the feasibility and cost-effectiveness of floating solar FPV installations. This article aims to provide a comprehensive review of case studies and comparative studies conducted to assess the techno-economic aspects of floating solar FPV systems.

  1. Case Studies: Evaluating Performance and Economic Viability

    Numerous case studies have been conducted to evaluate the performance and economic viability of floating solar FPV systems. These studies analyze various factors, including solar resource availability, system efficiency, power generation, and levelized cost of electricity (LCOE). By examining real-world installations in different locations, valuable insights can be obtained to inform future projects.

    Case studies have demonstrated that floating solar FPV systems can exhibit comparable or even superior performance compared to land-based solar PV installations. The cooling effect of water can enhance module efficiency and overall power generation. Additionally, the reduced competition for land and the potential to utilize water bodies that are not suitable for other purposes make floating solar FPV economically attractive in certain regions.

  2. Comparative Studies: Land-Based vs. Floating Solar PV

    Comparative studies between land-based and floating solar PV systems have been conducted to assess their techno-economic characteristics. These studies consider factors such as land availability, installation costs, system performance, environmental impacts, and economic indicators. By comparing the two approaches, the advantages and trade-offs of floating solar FPV systems can be identified.

    Comparative studies have revealed several advantages of floating solar FPV systems over land-based installations. Floating solar FPV can make use of underutilized water bodies, reducing land constraints and the need for land acquisition. Additionally, the cooling effect of water enhances module efficiency and can offset the higher installation costs associated with floating structures. However, site-specific factors, such as water quality, site accessibility, and regulatory considerations, must be carefully evaluated for each project.

  3. Techno-Economic Considerations and Cost Reduction Strategies

    Techno-economic analyses of floating solar FPV systems also involve considerations of various factors, including capital costs, operational and maintenance expenses, financing options, and government policies. These analyses help identify potential cost reduction strategies and highlight areas for optimization.

    To enhance the techno-economic feasibility of floating solar FPV systems, several strategies can be implemented. These include advancements in floating platform design, module manufacturing, installation techniques, and system monitoring and maintenance. Collaboration between industry stakeholders, research institutions, and policymakers can facilitate knowledge sharing and the development of best practices, ultimately driving down costs and improving the economic viability of floating solar FPV projects.


Techno-economic analyses, encompassing case studies and comparative studies, play a crucial role in assessing the feasibility and cost-effectiveness of floating solar FPV systems. These studies provide insights into system performance, economic indicators, and the advantages of floating solar FPV over land-based installations. By identifying cost reduction strategies and promoting technological advancements, floating solar FPV can become a competitive and economically viable solution for renewable energy generation.

Furthermore, supportive government policies, financial incentives, and streamlined regulatory frameworks can enhance the attractiveness of floating solar FPV investments. The knowledge gained from techno-economic analyses should inform future project planning and decision-making processes, leading to the widespread adoption of floating solar FPV as a sustainable and economically viable alternative in the global energy landscape.

Through continued research, innovation, and collaboration, floating solar FPV systems have the potential to contribute significantly to the transition towards clean and renewable energy sources, fostering sustainable development and mitigating climate change.
