                         food security in semi-arid regions. However, during severe 
                         droughts, the priority of energy demand leads to critical 
                         conditions of water availability. To reduce water use for energy, 
                         one possible measure is the adoption of solar power, an abundant 
                         energy source in semi-arid regions. This study assessed the 
                         influence of adding floating photovoltaic power (PV) in the 
                         largescale reservoir of Sobradinho HPP, located in the S ao 
                         Francisco River (SFR), in Brazil, from 2009 to 2018. The simulated 
                         scenarios varied the installed PV power capacity from 50 to 1000 
                         MW. For each scenario, water allocation was modified based on the 
                         solar-hydro equivalence that restrained the historical outflow of 
                         Sobradinho to maintain water in the reservoir. Besides, a diverse 
                         operation rule for the reservoirs in cascade of SFR was adopted to 
                         avoid ecological impacts of low streamflow. The scenarios were 
                         assessed in water security, solarhydro electricity output, 
                         capacity factor of the powerplant, water and energy losses by 
                         evaporation and spilled water. Results show that a PV system 
                         starting from 250 MW was necessary to improve water security 
                         during the severe drought, reserving 0.72.3 of the annual water 
                         demand. In addition, the capacity factor was optimized from 29% to 
                         3447%. However, as the HPPs installed at SFR work as one system, 
                         the constrain of the river flow reduced the hydroelectricity by 
                         4.4% for 750 MW. We concluded that PV significantly influenced 
                         water security and ecological conditions of SFR, with benefits in 
                         the range of 250750 MW. The research provides assessment on 
                         substituting hydro for solar power on the operation of reservoirs 
                         in cascade and identifies the correlated benefits in social and 
                         ecological aspects. This information can support decisions of 
                         water and energy supply system operators and public policies 
                         focused on integrated resources management in semi-arid regions.",
