Rooftop solar is the most accessible and cost-effective way to generate your own clean electricity. Whether you own a villa in Alanya, a factory in Kepez or a hotel in Belek, your roof is generating wasted potential every single day. Nexo Solar's rooftop systems capture that potential and convert it into real, measurable savings from day one.
Our rooftop systems use premium monocrystalline PERC panels — the highest-efficiency technology commercially available — paired with smart string or micro-inverters and our proprietary IoT monitoring platform. Every watt your panels produce is tracked, analysed and reported to your smartphone in real time.
From a 5 kWp home system to a 500 kWp commercial rooftop, our process is the same: a free survey, a custom engineered design, certified installation and full commissioning with grid connection. We handle every TEDAŞ/EDAŞ permit and inspection on your behalf.
How Rooftop Solar Works
Sunlight hits your panels and generates DC electricity. A grid-tied or hybrid inverter converts this to AC power which flows into your building's electrical system. Any surplus energy either flows back to the grid (earning you a net metering credit) or charges your battery storage system if you have one. Your IoT-connected monitoring box tracks every parameter — panel voltage, current, temperature, yield and CO₂ saved — accessible via our app.
Key Advantages
- Reduce electricity bills by 60–100% depending on system size and consumption
- 25-year performance warranty on all panels (typically degrading <0.5%/year)
- Antalya's 1,550 kWh/kWp annual yield — among the highest in Europe
- Net metering: sell surplus power back at regulated tariff
- Real-time fault detection via IoT — issues caught before they cost you money
- Property value increase: studies show solar adds 3–5% to property value
- Zero noise, zero emissions, minimal maintenance
Installation Process
Step 1 — Free Site Survey: Our engineer visits your property, assesses roof orientation and shading, analyses 12 months of electricity bills and designs your system. You receive a detailed proposal within 48 hours.
Step 2 — Design & Permitting: We prepare engineering drawings, submit grid connection applications to TEDAŞ/EDAŞ and obtain all necessary permits. This typically takes 2–4 weeks.
Step 3 — Installation Day(s): Our certified installation team arrives with all equipment. Mounting rails are fixed, panels are racked and wired, the inverter and monitoring unit are installed and tested. Most homes are done in a single day.
Step 4 — Grid Connection: We attend the official TEDAŞ/EDAŞ meter swap appointment and ensure your net metering is active and correctly set up.
Step 5 — Commissioning & Handover: We walk you through the monitoring app, explain your system and hand over all documentation. Your system begins generating — and saving — immediately.

Cost & ROI
A typical 10 kWp residential system in Antalya costs approximately ₺120,000–₺140,000 installed. With current electricity prices and Antalya's solar yield, this system will generate roughly ₺52,000 worth of electricity per year (at ₺3.50/kWh), giving a payback period of 2.5–3 years. After payback, the system generates free electricity for 20+ more years.
Commercial systems above 50 kWp typically achieve payback in 3–5 years and deliver internal rates of return of 18–25%, outperforming most alternative investments.

Detailed Financial Analysis: Rooftop Solar ROI in Turkey
Turkey's electricity prices have risen by an average of 45% per year over the past five years, making rooftop solar one of the highest-return investments available. In Antalya and the surrounding region, a correctly sized system typically pays back within 2.5–4 years — a return profile that outperforms most conventional asset classes. The combination of high solar irradiance and rising grid tariffs means that every year of delay costs you in both foregone savings and missed compounding.
* Based on ₺3.50/kWh tariff, 15% annual tariff increase, 1,550 kWh/kWp Antalya yield.
Antalya's Solar Advantage: Why This Region Outperforms
Antalya receives 2,956–3,060 sunshine hours per year — roughly double northern Europe and 30% more than Istanbul. The GEPA solar atlas puts Antalya's annual global horizontal irradiance at 1,971 kWh/m², giving installed systems a specific yield of 1,480–1,620 kWh per kWp annually. This means a 10 kWp system generates approximately 15,000–16,200 kWh per year, completely offsetting the average household's consumption.
- Peak summer (June–September): 8.5–9.2 kWh/m²/day
- Winter minimum (December): 3.1 kWh/m²/day — still productive
- Performance ratio: 79–84% (Antalya climate)
- Panel degradation: <0.5% per year (Tier-1 guarantee)
Net Metering: Turkey's Prosumer Scheme Explained
Turkey's EMRA (Energy Market Regulatory Authority) mandated net metering for all grid-connected prosumers in 2019. Under this scheme, surplus generation flows to the grid and is credited against future consumption on a 1:1 kWh basis. The credit is valid for 10 years from installation. Important details:
- Available to residential, commercial and small industrial customers
- No minimum system size — even a 1 kWp system qualifies
- Grid connection application (TEDAŞ/EDAŞ) handled entirely by us at no extra charge
- Meter swap to bidirectional smart meter completed as part of the project
Choosing the Right Technology
Panel quality varies enormously. Tier-1 (Bloomberg/PVEL classification) manufacturers carry sufficient financial strength to honour 25-year guarantees — lower-tier manufacturers may not. We exclusively install Tier-1 modules: LONGi Hi-MO6, JA Solar DeepBlue, Canadian Solar HiKu, and Jinko Tiger Neo. On the inverter side, Huawei SUN2000, SolarEdge HD-Wave, and Fronius Symo deliver proven 10–20 year field histories.
Mounting Systems: No Roof Left Behind
Every roof type has an engineered solution. Ballasted systems for flat roofs require zero penetrations. Hook mounts for tiled roofs are installed without removing tiles. T-bolt systems attach directly to trapezoidal steel without drilling. All systems meet IEC 61215 and local wind-load calculations for Antalya's coastal conditions.
Maintenance Over the System Lifetime
With no moving parts, solar systems demand minimal upkeep. A twice-yearly panel clean, periodic inverter health check, and remote monitoring platform (included with Huawei and SolarEdge systems) is essentially all that is required. Our IoT monitoring detects underperforming strings or individual panel faults in real time — often before the owner notices.
Environmental Impact
A 10 kWp rooftop system prevents approximately 350 tonnes of CO₂ over its 25-year life — equivalent to planting 175 trees annually. For hotels and businesses with ESG commitments or supply-chain sustainability requirements, rooftop solar provides measurable, verifiable carbon reduction that satisfies both regulatory and customer-facing sustainability goals.
