Currently only a small number of companies operate in imports, study and installation of photovoltaic systems in Greece. As regards wind power, the number of wind turbine suppliers that operate is small.
The annual installed capacity of photovoltaic systems in Greece reported an impressive development during 2011-2013. Since then it has registered a sharp fall and was particularly low in 2017. According to data from both the Hellenic Association of Photovoltaic Companies (SEF) and DAPEEP, the new installed capacity showed a small recovery in 2019. Therefore, the photovoltaic market has been on the rise. In 2020 new installed capacity of photovoltaic systems registered a sharp rise compared to 2019. The photovoltaic market value decreased by 10.9% in 2021 compared to 2020.
New installed capacity of wind systems registered a fall in 2021 compared to the previous year (-34.5%). Over the last decade, new installed capacity of wind systems has registered fluctuations, reaching its peak in 2019, 747 MW. 2019 was a "record" year for the wind energy sector, which despite the decline recorded in 2020-2021 is still of investment interest.
