The future massive deployment of renewable energies will also include the sector of offshore installations, which has not yet been exploited in Italy to date. Two technologies are considered in this report: wind technology, particularly floating, which is close to commercialization and offshore photovoltaic technology which is still developing. The technical-economic evaluations of integrated offshore wind and photovoltaic systems, even if of a preliminary nature and with a high degree of uncertainty, are important to guide the choices of all stakeholders.

To conduct such assessments, models capable of providing appropriate quantitative information both on the characteristics of the resource and on the performance of the devices considered are necessary.

For the evaluation of the possible compensation of wind and photovoltaic production in a given site, the concept of a typical meteorological year is introduced, the procedure for its construction is described and its application in an offshore site of interest in the Strait of Sicily, where RSE has installed a measurement buoy called MOBI buoy, is reported.

For production evaluation, RSE has already developed models for wind production, a refinement of which is presented. As regards the production from solar energy, the model adopted for calculating the performance of a photovoltaic panel is described.
The developed models are parametric and can be used in studies involving different configurations and different sites.
