A 4.4MW solar energy facility in Orestiada and a 2MW development in Evros were completed and interconnected by 26 July 2012.
The company said both systems are providing power to the Greek Public Power Corporation through 20-year power purchase agreements.
In addition, a 1MW solar energy facility is being constructed in Rhodopi and is scheduled for completion by mid-September.
SPI Solar chief executive Stephen Kircher said as Greece continues to diversify its energy sources, the firm will continue to pursue additional projects across the country.
"These are the first two large-scale SEFs we have completed in Greece, and they mark significant milestones for SPI," Kircher added.
The company has entered into a memorandum of understanding (MOU) with the Taneo Fund to develop 23MW of utility-scale solar energy facility across Greece; all of which are fully permitted and ready for construction.
As per the MOU, the goal for SPI Solar and Taneo is to potentially develop a total of 100MW across the country.
