Grid parity, where the cost of the kilowatt-hour produced by photovoltaics is less than the price of the kilowatt-hour acquired from the grid, is a recent success that in Italy made photovoltaics competitive even without incentives, and leads the continuing record-breaking growth at the global level of this technology. In this work, we show a sensitivity analysis for the Levelized Cost of Energy in the Italian domestic photovoltaic market. Moreover, we also propose a sensitivity analysis regarding the payback time related to the investment in a PV plant considering a 50% tax-reduction that is today available in the Italian market.
