The work of this thesis is placed in the context of the phenomenon known as "energy transition", which has been going on for several years all over the world. In fact, factors such as global warming, climate change and the problems of air pollution due to the emissions of hazardous substances are pushing public authorities to promote the generation of energy from renewable sources. In this scenario, a fundamental role is played by policies in the field of sustainability. In particular, for geographical and political reasons that granted very favorable incentives, Italy is positioned among the best producing countries in the world for the generation of solar photovoltaic energy.
