Ankara Utility Solar Design: Why 12.6MW Fits the Site
Resource and load profile
Ankara is a strong candidate for a utility-scale solar PV plant because its inland Anatolian location combines meaningful electricity demand with stable solar resource. The city sits at 39.93°N, 32.85°E and has a population above 5.8 million, which makes it a major industrial, public-sector, and logistics load center. For a site with 4.5 kWh/m²/day irradiance, a fixed-tilt ground-mount architecture is technically credible and easier to standardize than a rooftop-only approach.
Market context and grid fit
The project concept analyzed here is a 12.6MW DC configuration designed for Ankara’s grid environment. Türkiye’s distribution and transmission structure commonly uses 34.5kV/35kV-class medium-voltage collection, so a utility interconnection path with LV collection and step-up export is practical. The IEA (2024) notes that solar PV remains among the lowest-cost new-build generation options where land is available and irradiation exceeds 4.0 kWh/m²/day. That context supports Ankara as a credible B2B deployment zone for SOLARTODO-style engineering and procurement planning.
Core System Architecture and Performance Assumptions
Main electrical and mechanical specs
The recommended layout uses 21,749 TOPCon 580W modules, which yields 12.614MW DC nameplate capacity. The array is set at 25° fixed tilt, a geometry aligned with Ankara’s latitude and suitable for windy continental conditions where tracker complexity can add risk. The design also uses a central inverter with 98% CEC efficiency, a 5-year inverter warranty, and a 1.15 DC/AC ratio.
| Parameter | Value |
|---|---|
| Module type | TOPCon 580W |
| Module count | 21,749 |
| DC capacity | 12.614MW |
| Tilt angle | 25° |
| DC/AC ratio | 1.15 |
| Inverter efficiency | 98% CEC |
| Inverter warranty | 5 years |
| System life | 30 years |
Losses, yield, and degradation
Modeled total system losses are about 14%, split across 2% soiling, 3% shading, 2% mismatch, 3% wiring, and 3% availability. Under these assumptions, annual generation is estimated at 17,817,906 kWh. The module bank is specified with a 25-year warranty and 0.4%/year degradation, which supports long-horizon procurement and lifecycle modeling for a TOPCon n-type bifacial panel supply strategy.
Infrastructure, Export Path, and Environmental Impact
Collection and substation architecture
For a project of this size, the electrical backbone typically uses LV collection followed by step-up to 35kV before export to the substation. This is a standard architecture for a string inverter solar PV or central-inverter utility block, depending on EPC preference and site topology. In Ankara’s outer districts, the land-grid combination is better suited to a single utility block than to fragmented commercial rooftops.
Carbon reduction and sourcing implications
The modeled annual emissions benefit is approximately 7,484 tons of CO₂ reduction per year, which is roughly comparable to 336,780 trees on a standard equivalency basis. For B2B buyers, the key takeaway is that SOLARTODO can support procurement, system architecture, and component selection around a bankable utility design while keeping performance assumptions explicit and auditable.
