In July 2013, the Italian photovoltaic (PV) support policies changed the feed-in tariff (FIT)\udmechanism and turned to a tax credits program, which is currently in force. The aim of this paper is\udto investigate how such a radical change has influenced the electricity demand coverage of the PV\udsystems installed in urban contexts. A methodology, which connects the economic assessment to a\uddetailed architectural and energy suitability analysis, was applied to some case studies to analyse the\udrelationships between the physical parameters related to multi-storey buildings (roof shapes, number\udof floors and area of flats) and the most relevant economic and financial features affecting the viability\udof rooftop PV systems. The study, which considers only the electricity produced by the PV systems\udthat are economically profitable, highlighted that the tax credits scheme is even more effective in\udcovering the electrical consumption of densely urbanised Italian city districts. The results, which\udare significantly influenced by the latitude of the analysed districts, underline the opportunity for\udgovernments to adopt PV promoting policies that are more sensitive to the amount of solar energy\udavailable in the different regions of their national territory
