Researchers from the Renewable Energies Chair at the University of Évora in Portugal have concluded in a study on floating photovoltaic systems in Portugal that the installed capacity can exceed the national goal of 7 GW, defined in the National Energy and Climate Plan (PNEC) 2030 for PV energy in the electrical sector.

Researchers identified the region of Alentejo in south-central and southern Portugal as the area with the greatest potential as it combines water surfaces and solar resources.

The University of Évora said in a statement that even applying an 85% reduction to the total surface of water available at the national level, “the potential of floating photovoltaic solar energy systems can reach at least an estimated national capacity of 10.8 GW.”

“The analysis results from a mapping of the potential areas for floating photovoltaic solar systems applied in the national territory, establishing a relationship between the availability of solar radiation and the geographical distribution of the bodies of water in the different regions of the country,” said  Luís Fialho, a researcher at the University of Évora's Renewable Energies Chair.
