Ground mount solar plants offer the highest energy density and lowest levelised cost of electricity (LCOE) of any solar deployment model. With abundant land availability in the Antalya region and one of Turkey's highest solar irradiance levels (GHI ~1,850 kWh/m²/yr), ground mount projects deliver exceptional returns for landowners, investors, and industrial self-consumers alike.
Antalya Solar Energy Co. has delivered ground mount projects from 1 MWp on agricultural land to a 10 MWp utility-scale plant in Burdur. Our in-house engineering, procurement, construction, and commissioning capabilities mean complete project execution under a single EPC contract.
How Ground Mount Systems Work
Mono-crystalline panels are mounted on galvanised steel piling or ballasted foundations at an optimised tilt angle (typically 25–30° for Antalya latitude). Strings feed to central or string inverters located in weather-proof combiner/inverter stations. MV transformers step up voltage for grid injection, and a dedicated HV connection cable runs to the nearest TEİAŞ/TEDAŞ transformer substation.
For systems with a YEKDEM or YEK-G market licence, production is metered and sold to the grid at the applicable renewable energy support tariff or bilateral market price.
System Options & Technologies
- Fixed-Tilt: Lowest CapEx, optimal for sites with minimal shading and flat terrain. Typical yield: 1,500–1,600 kWh/kWp/yr in Antalya.
- Single-Axis Tracker (SAT): 15–25% higher yield vs. fixed tilt. East-west tracking of the sun. Higher CapEx but superior LCOE on large sites (>2 MWp).
- Bifacial Modules: 5–12% additional yield from rear-side reflection (especially on light-coloured sandy/gravel ground). We model bifacial gain in PVsyst for every project.
- Central vs. String Inverters: String inverters (Huawei SUN2000-100KTL) offer better MPPT granularity and easier maintenance. Central inverters (1.25 MVA) lower installation cost for very large plants.

Frequently Asked Questions
Solar farms can be built on marginal agricultural land (Class 6–8), pasture land with Ministry of Agriculture permission, and industrial/treasury land. Prime agricultural land (Class 1–4) requires special cabinet-level permission. We conduct land zoning analysis in the first phase of every project.
Systems up to 1 MW are exempt from EPDK generation licence (unlicensed, net-metering generation). Systems between 1–10 MW require a preliminary licence from EPDK followed by a generation licence. Systems above 10 MW follow a full EPDK licensing procedure with TEİAŞ connection study.
From contract signature: 3–4 months for licensing, 2 months for procurement, 3 months for civil and electrical construction. Total: 8–12 months. EPDK licensing (for systems over 1 MW) can add 6–18 months depending on the capacity queue.
Yes — agrivoltaic (dual-use) systems allow solar panels to share land with crops, livestock grazing, or beekeeping. We design agrivoltaic configurations with raised mounting structures (3m clearance) to maintain agricultural machinery access.
