The paper deals with the new course of the Feed-in Tariffs mechanism for photovoltaic systems that will start from January 1; 2011 in Italy with the actuation of the Government Decree DM 06/08/2010. After a short introduction on Feed-in Tariffs and Net-metering in Italy; the paper focuses the attention on an economical comparison between the incentives established by the Government Decree DM 19/02/07; ended on December 31; 2010 and those introduced by the DM 06/08/2010. The economical comparison is based on three indexes: the Pay Back Period; the Net Present Value and the Internal Rate of Return; characterizing the investments done for the realization of the photovoltaic systems. In particular; simulations show how the new Decree significantly penalizes the architectural integration; that represents a strongly criticism of the new incentive policy.
