A seguito del cambiamento climatico causato dalle emissioni inquinanti della combustione di combustibili fossili, diversi accordi sono stati sottoscritti a livello mondiale, europeo e nazionale, per aumentare la produzione di energia rinnovabile, riducendo le emissioni con l’obiettivo di rallentare e infine arrestare questi cambiamenti. Questi accordi impongono dei traguardi vincolanti riguardo la riduzione delle emissioni e la quota di rinnovabili nel mix di produzione energetica. In questa tesi si analizzano diverse strategie utili ad incrementare i guadagni generati dagli impianti fotovoltaici, in modo da individuare i metodi più efficaci per promuoverne la diffusione, aumentando le possibilità di raggiungere gli obiettivi sopracitati. Per avere una visione completa e realistica del panorama commerciale relativo al fotovoltaico, questa ricerca è stata condotto in collaborazione con Myenergy S.p.a.: azienda leader nella realizzazione di impianti fotovoltaici in Italia e in attività da 20 anni. Per raggiungere questo obiettivo sono stati studiati il design e la suddivisione di tutti i costi necessari alla realizzazione di un impianto fotovoltaico, in modo da avere un’idea chiara ed accurata dell’investimento iniziale. A seguito si è valutato il beneficio economico generato dagli impianti nel corso della loro vita utile, considerando il risparmio legato all’autoconsumo, i ricavi della vendita dell’energia in rete e le variazioni dei flussi economici nel tempo legate alla degradazione dei componenti e all’inflazione. Questi passaggi sono stati applicati allo studio di diversi casi reali, a cui sono stati applicati gli incentivi della comunità energetica, transizione 5.0, il FER-X e ISI Inail per l’amianto. Infine, son stati studiati anche il revamping e repowering di impianti esistenti, oltre all’utilizzo di sistemi di accumulo su impianti fotovoltaici industriali. I risultati ottenuti dimostrano miglioramenti concreti nei rientri di investimento, apportati da comunità energetiche, transizione 5.0, ISI Inail e revamping + repowering di impianti soggetti al Conto Energia. FER-X e sistemi di accumulo invece faticano a dare un apporto concreto all’aumento dei guadagni.

Abstract
Following the climate change caused by pollutant emissions from the combustion of fossil fuels, various agreements have been signed at global, European, and national levels to increase the production of renewable energy and reduce emissions, with the aim of slowing down and ultimately stopping this change. These agreements impose binding targets on the reduction of emissions and the share of renewables in the energy production mix. This thesis analyses different strategies to increase the economic benefit generated by photovoltaic plants, to identify the most effective methods to promote their diffusion and raise the chances of meeting the previously mentioned objectives. To obtain a complete and realistic view of the commercial photovoltaic landscape, this study was conducted in collaboration with Myenergy S.p.A., a leading company in the construction of photovoltaic plants in Italy and active for 20 years. To achieve this objective, the design and breakdown of all costs required to build a photovoltaic plant were studied, to provide a clear and accurate view of the initial investment. Subsequently, the economic benefit generated by the plants over their useful life was assessed, considering the savings linked to self-consumption, the revenues from the sale of energy to the grid, and the changes in cash flows over time due to component degradation and inflation. These steps were applied to the study of several real cases, to which incentives from energy communities, Transizione 5.0, FER-X, and ISI INAIL for asbestos cement were applied. Finally, the revamping and repowering of existing plants were also examined, as well as the use of storage systems on utility scale photovoltaic plants. The results obtained show concrete improvements in payback times brought by energy communities, Transizione 5.0, ISI INAIL, and revamping + repowering of plants under the Conto Energia. FER-X and storage systems, on the other hand, struggle to make a tangible contribution to increasing profits.| File | Dimensione | Formato | |
