About Italy solar energy supply
Government targets for renewable energy sources (RES) and different support schemes, especially for solar photovoltaics, resulted in an increase from 7.9% (2005) to 18.2% (2015) in total share of renewable energy in the total primary energy supply (TPES). 1.6% of the 18.2% renewables share is made up of solar energy.

Government targets for renewable energy sources (RES) and different support schemes, especially for solar photovoltaics, resulted in an increase from 7.9% (2005) to 18.2% (2015) in total share of renewable energy in the total primary energy supply (TPES). 1.6% of the 18.2% renewables share is made up of solar energy. From 2005 to 2015 solar power has increased on average by 63.7% per year. The share of renewables in electricity generation has increased from 17.2% in 2005 to 40.2% in 2015, including 9.3% of solar power. This is the highest share of solar in electricity among International Energy Agency (IEA) countries. And the third-highest share of solar power in TPES. Institutions Important institutions that are responsible for energy policies, the promotion and development of renewable energy, energy efficiency, co-ordination and payment of incentives are the Ministry of Economic Development (MSE), the Ministry for the Environment, Land and Sea (MATTM), the Ministry of Agricultural, Food and Forestry Policies (MIPAAF), the Regulatory Authority for Energy, Networks and Environment(ARERA, formerly AEEGSI, Autorità per l‘Energia elettrica e il Gas), the Gestore Servizi Energetici (GSE), the National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) and Terna. Policy The Directive 2009/28/EC establishes a framework for promoting the use of renewable energy sources. According to this Directive, 17% of Italy's final energy consumption must be supplied by renewable sources in 2020. Ital.
Solar power is an important contributor to electricity generation in , accounting for 11.8% of total generation in 2023, up from 0.6% in 2010 and less than 0.1% in 2000.Total installed solar power capacity in the country reached 30.3 GW at the end of 2023. Current (2023) government plans are targeting solar PV capacity to rise to 79 GW by 2030.Solar power is an important contributor to electricity generation in , accounting for 11.8% of total generation in 2023, up from 0.6% in 2010 and less than 0.1% in 2000.Total installed solar power capacity in the country reached 30.3 GW at the end of 2023. Current (2023) government plans are targeting solar PV capacity to rise to 79 GW by 2030.Like most countries, solar power usage in Italy was minimal before the 21st century. During the 2000s, however, Italy was the third country after Germany and Spain to experience an unprecedented boom in solar installations after actively promoting the energy source through government incentives. Solar capacity growth slowed in the 2010s, due to cessation of governmental subsidy programmes,but installations have picked up in the 2020s.
The entire nation of Italy retains high potential for solar energy production, ranging from 3.6 kWh per square meter per day in the Po river plain to 5.4kWh per square meter per day in .
Installed capacityInstalled capacity in Italy was less than 100 MW before 2008. Growth accelerated during 2008 and 2009 to reach over 1,000 MW installed capacity and tripled during 2010 to exceed 3,000 MW. The standout boom year in Italy was during 2011 when over 9,000 MW of solar power. Installed capacityInstalled capacity in Italy was less than 100 MW before 2008. Growth accelerated during 2008 and 2009 to reach over 1,000 MW installed capacity and tripled during 2010 to exceed 3,000 MW. The standout boom year in Italy was during 2011 when over 9,000 MW of solar power was added. This huge and rapid rise in installations was mostly due to the very generous "Conto Energia" support schemes operating during these years. A more responsive support scheme might have reduced support more quickly and lead to less rapid growth during 2011 but stronger medium term growth. By the end of the solar boom during 2011 Italy was second in the world in terms of installed capacity after Germany. Solar power accounted for 2.6% of electricity generated in the EU and 6.7% of electricity generated in Italy, the most in Europe. In 2011 Italy ranked first in installed solar power from new PV plants, with roughly four times the amount of power that was supplied in 2010.As of the end of 2010, there were 155,977 plants, with a total capacity of 3,469.9 MW. By the end of 2011 there were 330,196 installations, totalling 12,773 MW.Plants were increasing both in number and size as can be seen from the faster pace of growth of installed capacity compared with raw installation numbers.

Four types of CSP technologies are currently available on the market. These include , , power towers, and solar dish collectors.The 15 MWtis a thermal field atnear . The plant was inaugurated on 14 July 2010,and continues to be operational in a solar field of 31,860 square meters.It is the first concentrated solar power plant to usefor heat transfer and storage which is integrated with agas facility. Upon generating thermal energy, two tanks are available to store thermal energy for up to 8 hours.The two other CSP systems are the ASE demo plant,which usestechnology to focus solar energy, and the Rende-CSP plant, which uses technology to focus solar energy to one point of fluidised storage consisting of oil.Salerno based Magaldi Industries, partnered withand , pioneered a new form of CSP called Solar Thermoelectric Magaldi (STEM). The first plant of this type was pioneered inin 2016. This technology uses off-grid applications to produce 24-hour industrial scale power for mining sites and remote communities in Italy, other parts of Europe, Australia, Asia, North Africa and Latin America. STEM uses fluidised silica sand as a thermal storage and heat transfer medium for CSP systems.This fluidised bed benefits from a high thermal diffusivity and heat transfer coefficients, as well as high thermal capacity as a sol.
Italy has long sought to develop alternative energy resources due to having few domestic fossil fuel resources. Around 1850 wood,and straw were the main energy sources for many European countries. In Italy, due to a lack of coal, renewable from the Alps made industrialisation possible at the end of the 19th century. Using the local hydro resource. Italy has long sought to develop alternative energy resources due to having few domestic fossil fuel resources. Around 1850 wood,and straw were the main energy sources for many European countries. In Italy, due to a lack of coal, renewablefrom the Alps made industrialisation possible at the end of the 19th century. Using the local hydro resources made it also possible to be independent of coal imports. In 1914, 74% of the Italian electric power came from . By the early 1990s there were already pioneers of solar energy in Italy. One was the chemist . In his journal article, ‘The Photochemistry of the Future’ he predicted the use of solar energy. During , Italy was not able to prevent an energy crisis revealing the dependence on imported , mainly coal. After the crisis, hydro-power installations increased to ensure energy independence. This interest in locally available energy sources was in line with the economic self-sufficiency policies of the . With the promotion of these policies, research into renewable energy use increased. As a result, more than 90% of total electricity production was renewable energy by the start of . After World War II there was a change in policies. Energy demand was rapidly growing, and new policies aimed at supplying energy through importedand the development of . Due to these changes, dependence on imported fuels grew to more than 80% in 2005. With the .
