“…FPV systems are classified into three major groups based on their supporting structures: (1) Fixed Tilt arrays: rigid pontoons are required; (2) Tracking: it can be installed with or without pontoon; and (3) Flexible arrays: Due to the low weight, no supporting structure in the form of the pontoon is needed; FPV can also be classified based on the scale of implementation: small scale (few kW), medium scale (kW to MW) and large scale (MW to GW) [37]. Based on the different supporting structure designs of FPV systems, it can be classified as fixed floating PV systems [38], floating-tracking PV systems [39], and cooled FPV systems [40]. Floating-tracking PV systems have greater net capital costs than fixed floating PV systems, but they generate more electricity [41].…”

The world’s demand for electricity will double by 2050. Despite its high potential as an eco-friendly technology for generating electricity, solar energy only covers a small percentage of the global demand. One of the challenges is associated with the sustainable use of land resources. Floating PV (FPV) plants on water bodies such as a dam, reservoir, canal, etc. are being increasingly developed worldwide as an alternative choice. In this background, the purpose of this research is to provide an outline of the hybrid floating solar system, which can be used to generate renewable energy. The hybrid technologies discussed include: FPV + hydro systems, FPV + pumped hydro, FPV + wave energy converter, FPV + solar tree, FPV + tracking, FPV + conventional power, FPV + hydrogen. The review also summarizes the key benefits and constraints of floating solar PV (FPV) in hybrid operation. Among the various hybrid FPV technologies, with solar input and hydro energy were among the most promising methods that could be potentially used for efficient power generation. The valuable concepts presented in this work provide a better understanding and may ignite sustainable hybrid floating installations for socio-economic growth with less environmental impact.

“…In this context, FPV systems can be an effective solution to avoid evaporation while producing solar power. Several studies reported the effectiveness of the FPV systems in reducing the evaporation up to 90% through experimental and analytical investigations (Azami et al 2017;Liu et al 2017;Lopes et al 2020;Mckay 2013;Mittal et al 2017;Nagananthini and Nagavinothini 2021;Nazififard et al 2017;Ravichandran et al 2021;Rosa-Clot et al 2017;Santafé et al 2014;Taboada et al 2017). The significant observations in terms of installed capacity and water-saving effect of the FPV plants from the literature are outlined in Table 1.…”

“…An additional advantage of the FPV system is the possible combination of the FPV plants with the hydroelectric power plants (HEPPs) in the reservoirs. Recent studies reported that the combination of renewable technologies had resulted in a higher energy yield (Cazzaniga 2020;Lee et al 2020;Nagananthini and Nagavinothini 2021;Rosa-clot and Tina 2020). In India, the installed capacity of HEPP is about 44.95 GW, which accounts for 13.50% of the nation's total power generation capacity (MNRE 2019).…”

“…However, detailed studies on the suitability of this novel technology in India, with specific attention to hybrid FPV-HEPP systems, are scarce in the literature. Few studies had reported the performance analysis of model FPV systems in specific dams in India (Nagananthini and Nagavinothini 2021;Ravichandran et al 2021). But the large-scale performance analysis covering the entire nation to highlight the chances of potential improvement in solar power production in India is not available.…”

Floating photovoltaic system for reservoirs is a recent innovative technology that is highly advantageous in reducing evaporation while generating solar power. In addition, the integration of floating photovoltaic systems with the existing hydroelectric power plants will increase renewable power production. The present study aims to assess the electrical performance of floating photovoltaic systems in major reservoirs with existing hydroelectric power plants in India. The reservoirs with large water surface area were selected for the study, and a model floating photovoltaic system with a 5-MW capacity was designed for the selected reservoirs. The numerical analysis showed that installing floating photovoltaic systems will result in an annual energy yield of 160 GWh. Further, the systems also save 1.40 million cubic meters of water per day and also help in generating additional energy of 514.80 MWh/day from the saved water through its integration with hydroelectric power plants. A single-axis tracking mechanism to the floating photovoltaic systems will increase the annual energy generation by 11%. The detailed cost analysis and carbon emission analysis were also carried out. The results indicate that the tracking mechanisms increase the total installation cost of the systems. The annual carbon emission reduction from the floating photovoltaic systems accounts for about 3.30 million tons of CO2. The obtained results highlight the suitability of this innovative technology for installation in Indian reservoirs and its effectiveness in reducing evaporation and carbon emission. Graphic abstract

This study assesses the impact of implementing a floating solar photovoltaic system (FSPV) on the Turgutlu irrigation pond in Sakarya, Turkey, aiming to reduce energy expenses in agricultural irrigation and promote sustainability in farming. Two scenarios are developed to evaluate the FSPV, focusing on CO2 emissions mitigation, energy generation potential, evaporation reduction, conservation of terrestrial land, effects on agricultural production, decreased reliance on fossil fuels, and associated costs and return on investment (ROI). In the first scenario, the FSPV is expected to generate 7168 MWh of energy, preventing the emission of 4520 tons of carbon, and reducing annual evaporation by 6686 m3. In the second scenario, the FSPV's energy output is estimated at 99 MWh, preventing 64.2 tons of carbon emissions, and reducing annual evaporation by 94.4 m3. These findings provide valuable insights at the regional level, presenting a compelling case study for potential replication in other irrigated agricultural regions.
