They have surpassed two million installations. In Italy, 40 GW of photovoltaics are already connected.

The number of installed and grid-connected photovoltaic systems in Italy has exceeded two million devices. During the first seven months of this year, 132,276 new photovoltaic power plants were added, with a total installed capacity of 3,354 MW. This brings the total number of grid-connected PV systems to 2.01 million by the end of July, with a capacity exceeding 40 GW. According to the Italian solar association, the continued growth of installations, driven by households, industry, and energy companies, is raising awareness of the benefits of self-consumption. "We have passed a symbolic milestone. Two million systems mean millions of households, businesses, and public offices that have chosen a clean, reliable, and autonomous energy source. Photovoltaics is no longer a niche solution but an integral part of our energy infrastructure," says Paolo Rocco Viscontini, president of the Italia Solare association. "It is time to accelerate mechanisms that support self-consumption and the integration of electricity storage, overcoming the lengthy bureaucratic and legislative processes that still hinder the development of an energy system based on clean technologies, which will ensure low and stable electricity prices for our country in the long term." Although the average monthly installed capacity of residential photovoltaics for the first half of 2025 (88 MW) reached half of the record year 2023 (188 MW), it is still four times the installed growth compared to 2020. According to the association, this shows that demand remains relatively strong despite the reduction in subsidy support.

Economic Factors

"Two factors are driving demand. The first is the decrease in the price of technologies, not just photovoltaics but also and especially electrochemical technologies for electricity storage. The second factor is the growing awareness of the economic viability of photovoltaics," the association states. Data from the association indicates that, similar to elsewhere in Europe, large ground-mounted installations are increasingly contributing to Italy's PV growth at the expense of smaller systems. This is primarily related to the termination of the so-called "superbonus" subsidy for households. Residential installations slowed by 21% year-on-year last year, while the capacity of large-scale energy projects grew by 163%. Although the south of Italy has the most favorable natural conditions for photovoltaics, the regions with the largest installed capacities are located in the more economically developed north, where there is higher demand for electricity. In addition to Sicily and Puglia, the largest capacities are concentrated in the more densely populated regions of Lombardy, Emilia-Romagna, Veneto, and Piedmont.

Residential photovoltaics are also slowing down in Slovakia

Slovakia also saw a slowdown in the pace of residential PV installations last year. Distribution system operators connected 280 MW of new sources, primarily photovoltaic systems. Most of the capacity was installed by companies, while residential installations decreased, and large-scale projects traditionally saw low growth. The reason for the weaker interest in small-scale systems was the suspension of the "Green Households" subsidy program, which was not renewed until the summer of 2024. The subsidies for purchasing a photovoltaic system from EU funds were also quickly depleted this year, and support has been suspended for all regions of Slovakia except Bratislava.
