Abstract

This study investigates the techno-economic viability of Floating Photovoltaic (FPV) systems as a sustainable solution for Türkiye's energy requirements, in light of the increasing urge to tackle climate change and shift towards renewable energy sources. The analysis evaluates FPV deployment on 1% of the surface area of three hydroelectric power plant (HEPP) reservoirs—Sarıyar, Ermenek, and Kapulukaya—and compares them with Land-Based Photovoltaic (LPV) systems. This study includes not only energy generation and economic performance but also environmental benefits such as evaporation reduction and CO2 mitigation. The estimated annual energy generation for FPV systems is 2.6 TWh, 2.0 TWh, and 0.73 TWh for Sarıyar, Ermenek, and Kapulukaya, respectively, while LPV alternatives produce 1.3 TWh, 1.4 TWh, and 0.23 TWh. The Levelized Cost of Energy (LCOE) for FPV systems is calculated as 60.98, 55.53, and 55.28 €/MWh, compared to 51.36, 45.43, and 47.04 €/MWh for LPV systems. Although FPV systems yield higher energy production, LPV systems currently offer better economic feasibility under Türkiye's current market conditions. Nevertheless, developments in FPV technology could make FPV systems economically competitive and more advantageous in the near future.
