Case Study: Achieving 81% Energy Autarky in Antalya A Solar Project Due Diligence Report

December 26, 2025

In the realm of high-end solar investments, success is not determined by the hardware alone, but by the rigor of the engineering. For investors and homeowners, Solar Project Due Diligence is the critical process of verifying that a system can perform under real-world conditions before a single cable is laid.

This case study analyzes a luxury residential project in Döşemealtı, Antalya. It demonstrates how Lion Solar’s engineering-first approach transformed a high-consumption villa complete with an EV charger and heated pool into a self-sustaining energy fortress achieving 81.2% energy independence.

1. The Project Site & The Consumption Challenge

The first step of technical due diligence is understanding the load profile. This project was far from a standard residential installation. The villa in Döşemealtı presented a complex energy demand:

Location: Antalya, Döşemealtı (High solar irradiance, but also extreme summer heat which degrades panel efficiency).
Total Annual Consumption: ~14,901 kWh/year.
Critical Loads:
- Electric Vehicle (EV): An EV traveling ~18,250 km/year, requiring substantial overnight charging (~2,884 kWh/year).
- Swimming Pool: A 900 m³ indoor pool with circulation pumps running continuously (~4,000 kWh/year).

Without a precision-engineered solution, a standard solar setup would fail to cover these heavy loads, leaving the homeowner dependent on the grid during peak usage times.

2. The Engineering Solution: Combatting Heat & Managing Loads

To ensure maximum ROI (Return on Investment), we had to overcome the physical limitations of the Antalya climate. Solar panels lose efficiency as they get hotter. To mitigate this and manage the complex loads, Lion Solar deployed the following configuration:

A. Heat-Resistant Technology: Jinko N-Type TOPCon

We specified a 11.18 kWp array using 26x Jinko Solar Tiger Neo modules.

Why this matters: We selected N-Type TOPCon technology specifically for its low temperature coefficient. Unlike standard panels that suffer in 40°C+ heat, these modules maintain peak performance during Antalya’s hottest hours.
Precision Layout: Our 3D shading analysis confirmed that despite roof obstacles, shading losses were minimized to just 1.3%.

B. The Hybrid Storage Ecosystem: Huawei SUN2000 & LUNA2000

Generating power is only half the battle; storing it is the key to autarky.

Inverter: Huawei SUN2000-10KTL-M1 Hybrid Inverter.
Storage: A 10.2 kWh Huawei LUNA2000 Battery System.

This integration allows the “Green Mobility” concept to become reality. The battery stores excess midday sun to power the pool pumps at night and charge the EV after sunset.

3. Performance Results: The Data Behind the Promise

Using PV*SOL advanced simulation software, we conducted a technical due diligence stress test on the design. The results confirm the system’s ability to operate largely off-grid.

Total Yield: 18,273 kWh/Year. (Exceeding the home’s total need of 14,901 kWh).
Degree of Autarky:81.2%.
- What this means: For more than 80% of the year, this luxury home requires zero energy from the public grid.
Green Mobility: The simulation proves that out of the 18,250 km traveled by the EV annually, approximately 15,149 km are powered purely by the sun.

The “Energy Flow Graph” below visualizes this efficiency, showing how solar production (yellow) flows directly to the battery, the home loads, and the EV charger, with minimal grid interaction.

4. Environmental Impact

True luxury is sustainable. Beyond the financial savings, this project eliminates 6,772 kg of CO2 emissions annually. By replacing grid power with clean solar energy for both the home and the vehicle, the project creates a net-positive environmental footprint.

Why Engineering Matters

In the solar industry, equipment is a commodity, but expertise is the asset. This Döşemealtı case study proves that with the right components Jinko N-Type panels and Huawei Storage and Lion Solar’s rigorous engineering, energy independence is achievable even for high-consumption properties.
