This annual report, developed under IEA PVPS Task 1, provides a comprehensive overview of Italy's photovoltaic (PV) market, including installation data, policy frameworks, industry developments, and future prospects. Record Growth in Installations: In 2023, Italy added 5.2 GW of PV capacity, the highest annual increase in the past decade.
Since then, over 2 GW of Building Integrated Photovoltaic (BIPV) plants have been installed in Italy, including plants built beyond all the possible definitions of BIPV. The path to success for BIPV has been built on a number of requirements, for PV modules, buildings, and installation criteria, with a long-term vision.
From pv magazine Italy Italy's Council of State has issued two different rulings stating that agrivoltaic projects cannot be treated in the same way as conventional ground-mounted PV plants. A lawyer who followed the matter, Andrea Sticchi Damiani, told pv magazine Italy that these are only the first two rulings, with more to follow.
The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the TCP's within the IEA and was established in 1993. The mission of the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems.”
In 2005 the Italian government introduced the first feed in tariffs (FIT) specifically for photovoltaics connected to the grid, the Conto Energia schemes. The payments for the schemes were designed to be made over a 20-year period and to incentivise both smaller and larger producers to invest in the installation of photovoltaic plants and systems.
The Italian government has introduced incentives such as feed-in tariffs, tax credits, and simplified permitting procedures, fostering growth across all market segments. The continued emphasis on energy storage solutions, with nearly 300,000 systems installed in 2023, further enhances PV adoption.

The SisAl Pilot project produces solar-grade silicon from Spanish quartz without using coal and with zero CO2 emissions. The company behind the project claims that the process.
Currently (2012–2013) more than 90% of all solar cells produced are based on this vast group of technologies. The availability, the cost and the quality to the silicon feedstock is therefore a strategic issue of paramount importance for the entire photovoltaic sector.
However, Elkem of Norway developed a process for polycrystalline solar-grade silicon production and is building a 5000 metric tons plant . The major problem of the chemical route is that it involves the production of chlorosilanes and reactions with hydrochloric acid.
However, the vast majority of solar grade silicon (>90%) is still produced by the historical so called “Siemens” process applying chemical vapor deposition/CVD of high purity trichlorosilane/TCS/SiHCl 3 on a hot filament as this class of process currently is the only one available from technology suppliers and engineering firms.
In spite of the confusion on absolute cost, there is general agreement that the single largest operational cost driver for solar grade silicon production is energy consumption. Large energy consumption impacts negatively silicon economics, energy pay-back time and carbon emissions of PV.
SilBuCam, a Spanish consulting firm that specializes in metallurgical processes, is producing solar-grade silicon as part of the SisAl Pilot project in Spain. It is led by the Norwegian University of Science and Technology (NTNU) and involves 22 companies from nine countries on three continents, with a budget of €14 million ($13.9 million).
In the middle of the last decade hundreds of projects were announced to expand production capacity (both through debottlenecking, brown field projects and green field projects) as well as to develop new low energy, low cost processes more suitable for solar cells than the traditional and proprietary high cost, hyper purity polysilicon processes.
