Valle d’Aosta is the most efficient region in generating electricity from the sun, followed by Emilia Romagna and Piedmont. This is established by a study from Aceper (Association of Consumers and Producers of Renewable Energy), 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 sample of 5,236 photovoltaic systems across 17 Italian regions.

A region’s efficiency is determined by 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).

Aceper’s ranking shows the Aosta Valley as the leading region with the highest efficiency, producing 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. The national average is 65%.

In second place is Emilia Romagna, with 37,939,525 KWh produced and 43,840,630 KWh expected (an 87% ratio), followed by Piedmont, which is third with 139,917,414 KWh produced and 162,741,031 KWh expected (an 86% ratio), but is significantly first for KWh produced from photovoltaics.

There are then 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, which ranks second in 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 Italian region for production.
