Türkiye’s roof solar potential is ten times its current capacity

11 Dec 2023

Türkiye has a higher solar energy potential than most European countries, but currently lags behind in its share of solar electricity. In 2022, Türkiye generated 4.86%  (15.84 TWh) from solar, far below countries with lower potential and smaller surface areas such as the Netherlands 14.26% (17.29 TWh) and Germany 10.71% (60.01 TWh).

Rooftop solar has seen a huge boost in many European countries in recent years. Despite its limited land area, the Netherlands has become a leader in solar generation, thanks to a mix of policies, including net metering, subsidies, feed-in tariffs, and tax incentives. In the country 40% of solar electricity production is obtained from residential rooftops. Meanwhile, in Germany roofs host over 60% of the newly solar power plants each year. Overall, EU countries stand out in this regard, with 66% of total solar installed capacity on rooftops.

Rooftops are prioritised in energy transition policies across the world – and for good reason. Türkiye, which has ambitious solar targets, has a rooftop potential almost ten times its installed solar capacity. In addition to the current potential of roofs, tens of thousands of new buildings are being constructed every year in Türkiye with the rebuilding effort in the earthquake zone raising this figure even higher.

Introducing rooftop solar obligations for new buildings and public buildings, and the tendering of suitable apartment building roof areas by municipalities can both help Türkiye achieve its energy targets and enable people to generate their own electricity cheaply.

Methodology

The study calculates Türkiye’s technical potential of rooftop solar through an analysis of high resolution satellite images. Satellite images of roofs in 70 provinces were analysed and roofs were categorised based on their suitability for solar panels. The remaining 11 provinces declared disaster areas after the February 2023 earthquake were excluded. Microsoft Building Footprints database was used to identify roofs across the country and Google Earth Engine software was used to analyze satellite images.
