BTR EnerjiTürkiye solar tracker gain map: tracker and fixed-tilt yield in 81 provinces
How much more does a single-axis tracker produce than fixed tilt in each Turkish province? We simulated all 81 provincial capitals with the same method. The median gain is 19.7%.
Summary: across 81 provincial capitals, the tracker gain runs from 10.3% to 22.9%, with a median of 19.7%. The highest gains are in Mugla (22.9%), Kilis (22.4%), Isparta (22.3%); the lowest are in Artvin (10.3%), Trabzon (11.5%), Giresun (12.4%).
Gain and yield are not the same thing. For annual tracker yield, the top three are Mardin (2,262 kWh/kWp), Antalya (2,246 kWh/kWp), Aydin (2,197 kWh/kWp). Look at both when making an investment decision.

Method
- Calculation: our simulator itself, with an hourly PVGIS typical year for each provincial capital, 710 W bifacial modules and 10 hectares of land.
- Comparison: tracker and fixed tilt at the same installed capacity and row pitch (GCR 0.32). The fixed system faces south at a 35° tilt.
- Included: backtracking, wind stow, temperature, soiling, cabling, inverter and transformer losses.
- Not included: real terrain slope and near shading. Each point represents the provincial capital; coast and inland can differ noticeably within a province.
Simulation, not measurement. How the simulator compares with PVGIS: validation page. Comparison with world sites: solar tracker energy gain by location.

Frequently asked questions
Where in Türkiye does a tracker gain the most?
In this simulation the highest percentage gain is in Mugla (22.9%). Percentage gain and annual yield can rank differently; the table shows both.
Do these values apply to my site?
They give a direction, not a project calculation. Terrain slope, shading, module and inverter choice change the result. Run your site in the free simulator.
