Türkiye deployed 4,694 MW of new solar in 2025, according to data from the country’s national transmission system operator TEİAŞ, taking cumulative solar capacity to 24,795 MW.
Although down on the record amount of solar deployed in 2024, 2025’s figures represent continued momentum for Türkiye’s solar market, after 3.1 GW was added in the first half of the year and the country surpassed its annual deployment target by the end of June.
Unlicensed power plants generating electricity for self-consumption made up 4,175 MW of added solar in 2025 and now account for a total 22,255 MW.
Bahadır Sercan Gümüş, energy analyst at Ember, told pv magazine the share of residential solar in this figure is “negligibly small”, meaning nearly all of the unlicensed solar capacity in 2025 came from the C&I segment.
Gümüş explained that through most of 2025, businesses benefited from a policy mechanism that allowed solar power plants for self-consumption to be located in a different location from the consumption point.
