The installation of PV systems in residential buildings has significantly increased in the last decade, thanks to national programs such as Feed-in Tariffs and Net Metering. To maximize their earnings from these systems, some users must boost their self-consumption. Various components have been successfully tested, but there are still several challenges to overcome before these technologies can become fully viable. An initial purchase of a photovoltaic system requires a significant investment. This article outlines the cost of installing and wiring solar panels, inverters and related equipment. Additionally, conventional academic sections are included, and the language remains formal with no biased or emotional language. Lastly, correct spelling, grammar, and punctuation are employed. The article aims to provide an economic assessment of potential electricity bill savings via self-consumption in the residential sector of Rome, limiting the solar panel capacity between 1 kWp to 4.5 kWp. Technical terms are explained upon first use, ensuring the logical flow of information throughout. To fulfill this objective, we compare the situation of a typical Italian household, which solely relied on purchased power from the grid, with a hypothetical circumstance in which the residence participated in a scheme to construct a photovoltaic self-generation system that can meet some or all of its energy requirements. In Rome, employing "PV 1 kWp", we obtained a commendable result (IRR = 26%) and the greatest NPV (€4438.046).
