Abstract
A methodology that permits to test the level of integration of the photovoltaic technology in urban areas is presented. The percentage of coverage of the electricity demand and the economic feasibility of grid-connected photovoltaic systems installed on the roofs of buildings were investigated in a district of the city of Palermo (Sicily). After classifying roofs according to their shape, orientation and pitch by means of satellite images provided by Google EarthTM, the ratio of the productivity of the PV systems and the consumption of electricity of the households was analysed considering all economic aspects. As a result, it can be always identified the number of floors in correspondence of which the size of the PV system that may be installed, and the consequent production of electricity, does not recover the costs for installation and maintenance of the system.
