Renewable Energy - Floating Solar Farms in Romania

Abstract

The paper presents the possibility of floating photovoltaic farms on the reservoirs of the Olt river in Romania. For the analysis, a database with the solar irradiance evolution for one year in the four possible locations was created, using the PVGIS-SARAH2 database. The locations were chosen according to the surface area of the reservoir, geographical position, and possibility of connection to the national energy system. After the analysis, it was observed that during the cold season, the solar irradiance is higher in locations 1 and 2, while locations 3 and 4 show higher irradiance during the warm season. Simulations of electricity production were carried out for the location of solar farms, with an installed capacity of 1 MWh, with a southern positioning of the panels having different tilt angles of: 0, 15, 30 and 45 degrees. The paper continues with a statistical analysis of the monthly and annual electricity production when installing solar farms in the analysed locations.
