Ecological Impact versus Energy Generation by Floating Photovoltaic Power Plant for a Small Romanian Lake

The development of floating photovoltaic systems in Romania can help to the share of more than 30.7 % of the total energy produced from renewable energy sources set for the year 2030. Floating photovoltaic plants ensure the achievement of overall energy targets without affecting biodiversity and/or agricultural crops. This study evaluates the insolation and the possibility of installing this technology on Lake Făcău, Romania, to benefit from the generation of electricity but also better water quality and reduction of carbon dioxide emissions $\left(\mathrm{CO}_{2}\right)$. The obtained results are promising as Floating photovoltaic plants covering around 0.22 % of the lake surface, provide 26.76 $M W h /$ year and the estimated reduction of CO
2
emission is 7.52 $\mathbf{t C O}_{2 \mathrm{eq}} /$ year.
