180 W and a conversion efficiency equal to 13.6%. Consequently, models of Meteonorm software. Starting from the historical series
the array global power was equal to 2.7 kW. As regards solar radi- data and the geostatistical models implemented in Meteonorm,
ation assessment, it was estimated with a specific interpolation the Favignana island solar radiation on horizontal plane was
