According to a study by Aceper (Association of Consumers and Producers of Renewable Energy), which brings together 10,000 renewable energy production plants with over 7,000 members and a total installed capacity exceeding 2 GWp, the report provides the following insights.

The study was conducted on a large sample of 5,236 photovoltaic systems distributed across 17 Italian regions. Each region’s performance is assessed based on the ratio between actual photovoltaic production and expected photovoltaic production. Expected production is estimated using the official measurement tool Pvgis (Photovoltaic Geographical Information System), a program that calculates the actual production of the system, including projections for future years, considering variables such as installation location, month of interest, inclination, and orientation.

Aceper’s ranking shows Valle d’Aosta as the leading region with the highest efficiency, having produced 960,391 KWh (kilowatt-hours) against an expected production of 1,011,502 KWh, resulting in a ratio of 95% between actual and expected production.

Emilia Romagna is in second place, with 37,939,525 KWh produced and 43,840,630 KWh expected (an 87% ratio), followed by Piemonte in third place, with 139,917,414 KWh produced and 162,741,031 KWh expected (an 86% ratio). Piemonte ranks first for the total KWh produced by photovoltaics.

Three regions have 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, which ranks second 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 (an 84% ratio), making it the third highest producer. Marche, with 20,328,123 KWh produced and 24,622,400 KWh expected (an 83% ratio), precedes Tuscany, which has 5,830,869 KWh produced and 7,263,032 KWh expected (an 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. Umbria, with 21,396,944 KWh produced and 27,506,185 KWh expected, has a 78% ratio.

The subsequent regions are Sicily (2,325,953 KWh produced, 3,144,591 KWh expected, 74% ratio), Lazio (16,105,440 KWh produced, 22,635,310 KWh expected, 71% ratio), Campania (13,893,494 KWh produced, 19,822,080 KWh expected, 70% ratio), Sardinia (49,792 KWh produced, 71,369 KWh expected, 70% ratio), and Basilicata, which ranks last with 4,171,443 KWh produced, 6,836,095 KWh expected, and a 61% ratio.

“This research also considers the average ratio of production for Aceper members between actual KWh produced and KWh expected according to Pvgis, which stands at a satisfactory 79% for plants maintained and revamped by Aceper,” specifies Veronica Pitea, President of Aceper.

“However, the national average is around 65% productivity, a figure that concerns Aceper greatly. This is why we are requesting a meeting with the government as soon as possible to understand how to bring national production to at least 85%.

We need to focus on how to increase the power and productivity of our plants – concludes Pitea – not on how to save by reducing consumption.
