Recent industry data highlights Italy's significant progress in solar energy adoption throughout 2025. According to figures from the Italian grid operator Terna, as analyzed by the national photovoltaic association Italia Solare, the country added approximately 6.4 gigawatts (GW) of new solar photovoltaic (PV) capacity last year. This sustained growth has brought Italy's cumulative installed PV capacity to 43.5 GW by the end of December 2025.
The solar sector now represents a substantial portion of Italy's renewable energy landscape, contributing 52% of the nation's total renewable capacity. This expansion is supported by a diverse and growing base of over two million individual installations nationwide.
Industry experts point to several factors for this positive trajectory. A spokesperson for Italia Solare suggested that the actual installed capacity for 2025 might have been even greater, potentially nearing 7 GW. Furthermore, the association anticipates continued market growth in the coming years, fueled in part by government-led renewable energy incentive programs.
The integration of energy storage solutions is advancing alongside solar deployment. Data indicates that by the close of 2025, a significant number of new renewable energy systems were paired with storage, contributing additional grid flexibility.
