Calculateur de Batterie Solaire — Italie

Italy has the highest residential electricity prices in the dataset at $0.398/kWh — nearly double the US rate and 50% above the European average. This alone creates an enormous financial incentive for solar self-consumption. The country also has a rich solar history: the early Conto Energia feed-in tariff programs (2005-2013) made Italy one of the world's first mass solar adopters, creating a mature installation ecosystem and public familiarity with the technology.

The Scambio sul Posto (SSP) net metering scheme allows households with solar systems to offset their consumption on an annual basis. When your system produces more than you consume, the surplus is injected into the grid and credited — you can draw that credit back when your production falls short. The Gestore dei Servizi Energetici (GSE) administers the program, providing a centralized and transparent process.

Key advantage: Southern Italy — Sicily, Puglia, Calabria, and Sardinia — receives over 5.0 kWh/m²/day of solar irradiance, rivaling North Africa. Even the Po Valley in the north receives ~3.5, which is comparable to central France. Battery storage is particularly valuable under SSP because it shifts your self-consumption to high-value evening hours when Italian time-of-use tariffs (monoraria/bioraria) are most expensive.
