The price of roof-mounted residential photovoltaic (PV) systems in Italy decreased from 3.6 euros per watt in 2011 to 1.45 euros per watt in 2023. A similar trend can be observed in the prices of commercial and industrial PV systems and ground-mounted plants. The growth of the solar PV sector in Italy made the market more competitive.  
Growth of the PV market in Italy
In fact, the number of photovoltaic systems in Italy experienced a 10-fold increase between 2010 and 2023. Also, the cumulative installed capacity grew steadily, peaking in 2023 at 30 gigawatts. Lombardy was the region with the greatest share of PV installed capacity nationwide, followed by Veneto.  
PV in Italy’s power mix
The share of renewable electricity produced from solar PV facilities in Italy increased by almost 10 percentage points between 2018 and 2023. The southern regions of the country have a high potential for solar installations given the frequent sunny days, and this figure is expected to increase in the next few years.
