In 2021, the Greek photovoltaic market installed more megawatts (MWp) than any other technology, as a result of the huge investment interest that continues unabated.
Interconnected systems MWp
New power of interconnected photovoltaics in 2021 – 838
Total power of interconnected photovoltaics until 2021 – 4,126

Of the 838 MWp of photovoltaics interconnected in 2021, 454 MWp had declared a readiness by 2020 but were electrified in 2021. Similarly, an additional 370 MWp made a declaration of readiness in 2021 but will be electrified in 2022.
In 2021, the market for self-generating systems more than doubled compared to the previous year. More specifically, 38 MWp of new systems with energy offset or virtual energy offset were installed, raising the total power of this category to 89 MWp.
Self-production
Newly installed power 2021 – 38 MWp (98% commercial, 2% domestic in terms of power)
Total power of self-production – 89 MWp (96% commercial, 4% domestic in terms of power)
Contributing to demand and reducing emissions
In 2021, photovoltaics in Greece produced 5.26 TWh (billions of kilowatt hours) or 9.2% of the country’s electricity demand (about the same as lignite production), eliminating the release of 3.7 million tons of CO2 from fossil fuel substitution.
