Italy has surpassed 40 GW of installed solar PV capacity, with more than two million grid-connected systems nationwide. In the first seven months of 2025 alone, 132.276 new systems were added, totaling 3,35 GW, according to data from the association. Solar Italy.
Although the current pace represents a slight slowdown compared to the 6,8 GW of 2024, the sector maintains stable growth, driven by residential, commercial, industrial and public services.
According to Italia Solares, Italian solar installations are concentrated in regions with larger populations, reflecting a greater demand for electricity. Lombardy leads among the most supplied regions (5,4 GW), being the most populous region in the country, with more than ten million inhabitants.
Similarly, Lazio and Campania, both with over five million inhabitants, have cumulative solar installations of 3,8 GW and 1,7 GW, respectively. Italy currently has a population of 59 million.
Growth and new auctions
In parallel, the state agency GSE launched a new renewable energy auction under the "FER X Transitory" decree. With a cap of up to 8 GW of solar energy to be added, the auction received 1,3 proposals, totaling 17,5 GW of interested projects. The strike price was set at €76,37/MWh.
"We've reached a symbolic milestone: two million systems represent millions of families, businesses, and governments that have chosen a clean, reliable, and autonomous energy source," said Paolo Rocco Viscontini, president of Italia Solare. He added that it's time to "overcome the bureaucratic slowdown" to ensure low prices and energy stability.
The government also relaunched a €323 million call for proposals for agrovoltaics, following underutilization of previous funding. The strategy reinforces the role of solar energy as a central axis of Italy's energy transition.
