A recent investigation by researchers at Sapienza University of Rome has determined the optimal locations for deploying offshore floating photovoltaic systems in Italy. The work, which appears in the journal Energy for Sustainable Development, employed a geospatial multi-criteria evaluation framework to gauge technical viability.
The team utilized QGIS software to merge oceanographic, environmental, and operational information, producing a feasibility index ranging from zero to one for both offshore and nearshore zones. Ten critical factors were integrated into the model: wave height, wave period, wind speed, current speed, bathymetry, distance from the coastline, fishing activity, marine protected zones, and ferry routes. Each factor was assigned a suitability rating derived from engineering limitations and published research. A Hydrodynamic Severity Index was also developed, merging wave height and peak period to more accurately depict conditions impacting floating structures.
The spatial evaluation pinpointed highly appropriate offshore zones in the Adriatic Sea, the Gulf of Taranto, specific areas surrounding Sicily, and portions of Sardinia. These sites are characterized by moderate wave and wind patterns, advantageous bathymetry, and relatively short distances to the shore.
Principal author Leonardo Micheli stated that the group pinpointed appropriate zones for offshore floating PV deployment by applying realistic limitations based on present industry practices, constraints, metocean conditions, and bathymetric data. The Italian Exclusive Economic Zone was employed as a representative example. Locations were categorized according to their degree of appropriateness; certain variables, like protected zones and ferry paths, served as binary exclusion factors, whereas others were evaluated using a continuous suitability ranking.
The analysis revealed that utilizing merely 2% of Italy’s technically viable offshore solar area could theoretically produce sufficient electricity to satisfy the nation’s yearly power consumption of 306.1 TWh. Sensitivity checks confirmed that, even under cautious projections, only a minor portion of the identified appropriate marine area would be necessary to fulfill national electricity needs.
The researchers observed that offshore floating PV is still in an early developmental phase because of the technical difficulties associated with functioning in severe marine settings. Notable obstacles include corrosion from saltwater, structural strain from waves and wind, increased upkeep demands, and higher levelized electricity costs. Environmental issues also continue, especially concerning effects on marine life, disruption of the seabed, and diminished light penetration through the water. Earlier studies indicated that wave motion can change module tilt and orientation, potentially decreasing yearly energy output by as much as 9% during harsh sea conditions.
Nevertheless, the scientists pointed out that offshore installations could gain from large, unobstructed areas, strong solar radiation, and reduced operating temperatures due to cooler surroundings and stronger winds, which can boost module efficiency. They also have minimal visual impact and can be situated alongside offshore wind farms, allowing for shared infrastructure, more consistent power generation, and reduced overall system expenses.
The study concluded that, with ongoing technological progress and decreasing costs, offshore floating PV could emerge as a competitive and supplementary element of the national energy mix, especially in nations with dense coastal populations and abundant solar resources. The modeling method can be readily adapted to other areas.
