Italy installed 4.83 GW of new solar capacity in the first nine months of 2026, with 147,632 new systems connected to the grid, according to data released by industry association Italia Solare. As a way of comparison, the newly installed PV capacity for the January-September period in 2025 was 4.08 GW across 161,962 new installations
The additions brought the country’s cumulative installed PV capacity to 48.35 GW across 2,314,113 systems at the end of September 2026.
The figures are based on Italia Solare’s analysis of data from Italian grid operator Terna’s Gaudì database, covering PV and energy storage installations connected to the grid through the third quarter of 2026.
In the third quarter alone, Italy connected 1.74 GW of new PV capacity, up 5% from 1.65 GW in the second quarter and 37% from 1.27 GW in the third quarter of 2025. The number of new connections also increased, rising from 38,660 in the second quarter to 58,459 in the third quarter, a 51% quarter-on-quarter increase.
The data indicate that the Italian solar market continued to expand in the third quarter, with utility-scale projects accounting for the largest share of new capacity.
Utility-scale projects dominated the Italian PV market in the first nine months of 2026, accounting for 2.24 GW of newly connected capacity across 473 installations, or approximately 46% of the total.
70 GW across 11,905 installations, representing 35% of new capacity. Residential installations of up to 20 kW accounted for 897 MW across 135,254 systems, equivalent to approximately 19% of newly connected capacity.
