<p>Italy deployed 6,437 MW of new PV capacity in 2025, according to new data released by Italian grid operator Terna and elaborated by the national PV association Italia Solare.</p>
<p>By way of comparison, the country added <a href="https://www.pv-magazine.com/2025/02/20/italy-adds-6-8-gw-of-solar-in-2024/" rel="noopener" target="_blank">6.8 GW in 2024</a>, <a href="https://www.pv-magazine.com/2024/02/20/italy-added-5-23-gw-of-new-solar-in-2023/" rel="noopener" target="_blank">5.23</a> GW in 2023 and 2.48 GW in 2022, and 0.94 GW in 2021.</p>
<p>Italy’s cumulative installed solar PV capacity reached 43.5 GW at the end of December 2025. Of this total, 27% (11,627 MW) comes from residential systems, 43% (18,850 MW) from commercial and industrial (C&amp;I) installations, and 30% (13,036 MW) from large-scale plants.</p>
<p>“Last year’s new capacity represents a 5% decrease compared to 2024, primarily due to a slowdown in the residential and C&amp;I sectors, partially offset by increased large-scale plant connections,” said Italia Solare. “The number of new systems also declined in 2025, with 213,200 installations, down 25% from 283,914 in 2024.”</p>
<p>Residential installations appear to have stabilized at an average of 300 MW per quarter, representing a 24% reduction in capacity compared to 2024. The number of systems installed also fell, from 274,537 in 2024 to 198,667 last year, the association added.</p>
<p>The final quarter of 2025, buoyed by the commissioning of several utility-scale plants, saw an acceleration in connected capacity, with approximately 2.4 GW added out of a total 6.4 GW installed during the year.</p>
<p>The utility-scale segment recorded 15% growth, with numerous large-scale plants connected to the grid — 2,910 MW in 2024 compared to 3,412 MW in 2025.</p>
<p>This increase reflects the wave of authorizations issued in recent years. Data analysis shows a strong acceleration for plants above 10 MW, with a growing share of connections occurring in the final quarter alone (1,031 MW), exceeding the combined total of the previous three quarters (688 MW).</p>
