This was established by a study conducted by ACEPER (Association of Renewable Energy Consumers and Producers), which brings together 10,000 renewable energy production plants, representing over 7,000 members with a total installed capacity exceeding 2 GWp.

The study was conducted on a very large sample of 5,236 photovoltaic systems located across 17 Italian regions. A region is considered more or less virtuous based on the ratio between actual photovoltaic production and expected photovoltaic production, where the expected production is estimated according to the official measurement tool PVGIS (Photovoltaic Geographical Information System). This program allows for an accurate calculation of the system’s production, including projections for the coming years, taking into account variables such as installation location, month of interest, tilt, and orientation.

The Ranking

Now let’s look at the ACEPER’s ranking, which, as anticipated, places the Aosta Valley at the top as the most virtuous region with 960,391 kWh (kilowatt-hours) actually produced and an expected production, according to PVGIS measurement, of 1,011,502 kWh, resulting in a real-to-expected production ratio of 95%. The second spot goes to Emilia Romagna, with 37,939,525 kWh produced and 43,840,630 kWh expected (87% ratio), followed by Piedmont, third with 139,917,414 kWh produced and 162,741,031 kWh expected (86% ratio), but clearly first in terms of kWh produced from photovoltaics.

Next, we have three regions with an 85% ratio: Abruzzo, with 20,100,052 kWh produced and 23,625,127 kWh expected; Liguria, with 5,187,522 kWh produced and 6,108,499 kWh expected; and Lombardy, second in the ranking for photovoltaic production with 66,305,239 kWh produced and 78,089,977 kWh expected. Veneto follows, with 49,221,066 kWh produced and 58,691,563 kWh expected (84% ratio), the third Italian region for production. The Marche, with 20,328,123 kWh produced and 24,622,400 kWh expected (83% ratio), precedes Tuscany, with 5,830,869 kWh produced and 7,263,032 kWh expected (80% ratio).

Molise, with 1,589,155 kWh produced and 2,000,284 kWh expected, and Puglia, with 18,459,422 kWh produced and 23,406,458 kWh expected, both have a 79% ratio, while Umbria, with 21,396,944 kWh produced and 27,506,185 kWh expected, has a ratio of 78%. Following are Sicily (2,325,953 kWh produced, 3,144,591 kWh expected, and a 74% ratio), Lazio (16,105,440 kWh produced, 22,635,310 kWh expected, and a 71% ratio), Campania (13,893,494 kWh produced, 19,822,080 kWh expected, and a 70% ratio), Sardinia (49,792 kWh produced, 71,369 kWh expected, and a 70% ratio), and Basilicata, which closes the ranking with 4,171,443 kWh produced, 6,836,095 kWh expected, and a 61% ratio.
