The residential photovoltaic system installed in Agropoli, in the province of Salerno, has a power output of 4.92 kWp and covers an area of 25 square meters. Thanks to this solution, an annual energy production of approximately 6,540 kWh is estimated, allowing for a self-consumption rate of 65%, which means that most of the energy produced is used directly by the home, significantly reducing electricity costs. The system was built using JASolar photovoltaic modules and a Zucchetti inverter.
