Rooftop solar is the most capital-efficient form of renewable energy for commercial and industrial businesses. By generating electricity directly at the point of consumption, you eliminate transmission losses, reduce peak-demand charges, and hedge against rising grid tariffs — all from an asset on your own roof.
Antalya Solar Energy Co. has designed and built over 40 commercial rooftop systems ranging from 150 kWp factory installations to 2.4 MWp logistics centre projects. Our end-to-end EPC service removes every complexity from the client's plate.
How Commercial Rooftop Solar Works
Solar panels (photovoltaic modules) convert sunlight into DC electricity. String or central inverters convert DC to grid-compatible 3-phase AC electricity, which feeds directly into your main distribution board. Your building uses this solar power first; any shortfall is drawn from the grid as normal, and surplus production is exported under net metering at the retail tariff rate.
With Huawei FusionSolar or SolarEdge monitoring, you can track real-time and historical production from any device, set consumption alerts, and access monthly performance reports.
Key Advantages for Your Business
- Immediate reduction in electricity costs — typically 60–90% of daytime consumption offset
- Protection against electricity tariff inflation (average +15%/yr in Turkey since 2020)
- Positive EBITDA impact from year one in most industrial scenarios
- Net metering credit for surplus energy (10-year regulatory commitment)
- Carbon footprint reduction for ESG reporting and green procurement tenders
- Increased property/asset value (solar as a capital improvement)
- No roof penetration required for trapezoidal steel profiles — ballasted aluminium rail system

Investment & Financial Returns
For a typical Antalya industrial facility consuming 500,000 kWh/yr, a 320 kWp rooftop system would:
- Cost approximately ₺3.84M (turnkey EPC)
- Generate ~496,000 kWh/yr (offsetting 99% of consumption)
- Deliver ₺1.74M/yr in electricity cost savings at current tariff
- Achieve simple payback in 2.2 years
- Generate ₺23M cumulative savings over 25 years
- IRR approximately 38% — comparable to highly profitable business investments
Financing options: Green energy bank loans (preferential rates via Garanti BBVA, İş Bankası, Halkbank), operating lease structures, and PPA models where no upfront capital is required.

Frequently Asked Questions
Trapezoidal steel profiles (most common in industry), concrete flat roofs, membrane (TPO/EPDM) roofs, and fibre-cement panels. We perform structural load analysis for every roof type before proposing a mounting system.
For trapezoidal steel roofs we use clamp-based aluminium rail systems that do not penetrate the roof surface. For flat roofs we use ballasted systems or penetrating anchors with EPDM seals and extended warranty from the roofer.
Building permit: 4–8 weeks. TEDAŞ net metering application: 6–12 weeks. We submit both in parallel and typically complete grid commissioning within 12–16 weeks of contract signing for systems up to 1 MWp.
Panels still produce at reduced output (typically 10–25% of peak capacity) on overcast days. Antalya has 300+ sunshine days per year making it ideal for solar. Any shortfall is automatically drawn from the grid — no interruption to operations.
For most C&I clients with daytime operations, battery storage is not required and not financially justified currently. The payback on batteries adds 3–4 years. However, for clients needing backup power, zero-export (no grid export), or night-time self-consumption, we offer hybrid inverter + LiFePO4 battery options.
