Solar power in Greece

Development of solar power in Greece started in 2006 and installations of photovoltaic systems skyrocketed from 2009 because of the appealing feed-in tariffs introduced and the corresponding regulations for domestic applications of rooftop solar PV. In 2019, 90% of the ca. 2.5 GWp capacity was installed in 2011, 2012 and 2013. However, funding the FITs created an unacceptable deficit of more than €500 million in the Greek "Operator of Electricity Market" RES fund. To reduce that deficit, new regulations were introduced in August 2012 including retrospective feed-in tariffs reduction,[1] with further reductions over time.[2] These measures enabled the deficit to be erased by 2017.[3]

Auctions have replaced FITs and after stagnating since 2013, as of 2019 Greece is again installing hundreds of MWp per year.[3] By May 2022,[4] the installed capacity of Photovoltaic systems, in the interconnected grid, has reached a total installed capacity of 4199 MWp for large parks. Moreover, anothe 352 MWp of rooftop - photovoltaic systems with a net power output of less than 10 kWp are also installed by this date.

By April 2015, the total installed photovoltaic capacity in Greece had reached 2,442.6 MW_p from which 350.5 MW_p were installed on rooftops and the rest were ground mounted.[5] Greece ranks 5th worldwide with regard to per capita installed PV capacity and PV covers 7% of the country's electricity demand in 2019.[3]
