Italy has crossed a major renewable energy milestone, exceeding 2m grid-connected PV systems and 40GW of installed capacity, according to new figures from ITALIA SOLARE.

As of 30 July 2025, the country counted 2,011,056 PV systems with a combined capacity of 40,430 MW. In the first seven months of 2025 alone, 132,276 new systems were connected, adding 3,354 MW.

Paolo Rocco Viscontini, President of ITALIA SOLARE, commented:

“We have reached a symbolic milestone: 2m installations represent millions of families, businesses, and governments who have chosen a clean, reliable, and autonomous source. Today, photovoltaics is no longer a marginal option; it is an integral part of our energy infrastructure.”

Viscontini urged policymakers to remove barriers slowing down further development:

“It’s time to accelerate the mechanisms that support self-consumption and integration with storage, overcoming the bureaucratic and legislative slowness that is still hindering the development of an energy system based on clean technologies that can ensure our country’s low and stable energy prices over time.”

Residential growth and incentives

Between 2020 and 2024, residential PV connections in Italy grew significantly. Average monthly installations rose from 22 MW in 2020 to 140 MW in 2024, with a peak of 188 MW in 2023 during the height of the Superbonus scheme.

In the first half of 2025, installations averaged 88 MW per month – four times higher than pre-Superbonus levels, indicating strong demand even without extraordinary incentives.

The trend has been supported by falling technology costs, particularly in photovoltaic and electrochemical storage, and rising consumer awareness of the financial benefits of solar.

Regional distribution

The regions with the highest number of solar systems are also some of Italy’s most populous. Lombardy leads with 326,586 PV systems, followed by Veneto (274,699), Emilia-Romagna (198,003), Lazio (141,210), Sicily (136,511), and Piedmont (134,729).

In terms of installed capacity, Lombardy again ranks first with 5,419 MW, followed by Veneto (4,055 MW), Puglia (3,912 MW), Emilia-Romagna (3,855 MW), and Lazio (3,787 MW).

Driving the energy transition

ITALIA SOLARE noted that solar’s role is becoming increasingly central as electrification accelerates across heating, mobility, and industry.

“Photovoltaics, integrated with storage systems and digitalisation, meets these needs and enables a more flexible and participatory system,” the association said.

With the European Union targeting full decarbonisation of building stock by 2050, Italy’s PV sector is expected to continue expanding.
