Choosing land for a solar power plant (GES)

GES stands for güneş enerjisi santrali, a solar power plant. Whether a piece of land is suitable for solar power depends not only on the sun but also on its slope, the grid and permits.

1. Solar yield (kWh/kWp)

The energy produced in a year by 1 kWp of panels in Türkiye is roughly 1,300–1,750 kWh depending on the region; the south and the interior are higher. The ParselX "Solar potential" card makes an estimate for the parcel using PVGIS (European Commission) data.

2. Slope and aspect

Flat land or a gentle slope facing south is ideal. On a steep north-facing slope, the rows of panels shade each other and more land is needed. The ParselX "Slope and elevation" card shows the average slope and aspect.

3. Grid connection

The most critical issue is usually connection capacity: if there is no room at the local transformer substation, the plant cannot be connected. Apply to the electricity distribution company for your area.

4. Unlicensed generation

A solar plant built without a licence is linked to a consumption point (an electricity subscription); the capacity that can be installed and the energy that can be fed into the grid are limited according to that consumption.

5. Agricultural land and zoning

On agricultural land, requests for ground-mounted solar plants are only put on the agenda of the Soil Conservation Board (Toprak Koruma Kurulu) for land classed as "dry marginal agricultural land" (Regulation on the Protection and Use of Agricultural Land, Official Gazette (RG) of 04.04.2026). This class is determined by a survey commissioned from the Provincial Directorate of Agriculture and Forestry. An energy generation area designation in the zoning plan may be needed.

6. Land needed

Roughly 15–20 dönüm of land is needed for 1 MWp (a dönüm is 1,000 m², so this is about 1.5–2 hectares; it varies with the panel type and the spacing between rows).
