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. This "downfall" of the market is mainly due to the lack of funding and the structural changes in the institutional framework.
Solar panels accounted for 50% of the domestic market of photovoltaic systems (based on value) in 2018.
The annual installed capacity of wind systems has registered fluctuations over the last three years (2016-2018).
