In 2025, the Greek photovoltaic market installed more megawatts (MWp) than any other technology for yet another year, a result of the enormous investment interest. Specifically, according to data from the Association of Photovoltaic Companies, photovoltaics accounted for 84.2% of all new installed renewable energy capacity for that year.
Grid-connected systems (MWp)
- New grid-connected photovoltaic capacity in 2025: 1,840
- Total grid-connected photovoltaic capacity by 2025: 11,538
In 2025, at least 800 MW of additional photovoltaic stations were constructed; however, these were not connected to the grid during the year, and their connection is scheduled for 2026. Although we did not include them in the connections, the related investments and jobs were calculated for 2025 to provide a more realistic picture of the market.
Of the interconnected systems in 2025, 14.4% were self-consumption systems. In 2025, the market for self-consumption systems saw a significant decline and remained at 2023 levels.
This decline is primarily due to the sharp contraction of the residential self-consumption system market following the expiration of the “Roof-Top Photovoltaics” subsidy program .
Of the 5,180 residential systems connected in 2025, 2,795 were also equipped with a battery (49.2%).
In 2025, photovoltaics generated more energy than wind power for the first time, taking the top spot among renewable energy sources. In 2025 alone, €1.65 billion was invested in new photovoltaic projects in our country. This growth was accompanied by the creation of 26,600 full-time equivalent jobs.
In residential and small commercial projects, employment is estimated to have decreased by approximately 2,000 jobs, which were offset by larger projects and the first batteries installed in 2025.
Thanks to photovoltaics, 6.3 million tons of carbon dioxide (CO2) emissions were avoided in 2025. This is the amount of CO2 emitted by 5.4 million new cars with internal combustion engines, each traveling an average of 10,000 kilometers per year. The environmental benefit is equivalent to what we would achieve if we planted 163 million conifers or, respectively, 99.5 million deciduous trees within the urban fabric and let them grow for a decade.
