1. Analysis of solar photovoltaic energy potential in Brazilian hydroelectric reservoirs through floating panels
Abstract Sustainability, a concept used to exploit natural resources without harming future generations, is being applied to power generation. In Brazil, the main source of electric energy comes from hydroelectric plants, due to abundant water resources. However, the implementation of these plants causes irreversible impacts on the environment and society.
