About Solar PV Technologies

Solar energy systems are composed of integrated components — including panels, inverters, mounting structures, cabling, electrical boards, and monitoring solutions — built on the principles of high efficiency and long-term reliability.

1. Solar PV Modules

High Efficiency, Long Lifespan, and Maximum Energy Output

Solar photovoltaic (PV) panels are the fundamental components of solar energy systems, converting sunlight directly into electricity. Dev Marmara projects utilize high-efficiency modules in the 455 W, 550 W, 590 W, and 640 W power classes. The latest N-Type TOPCon technology provides lower temperature coefficients and higher conversion efficiency, resulting in greater energy yield.

With their glass-glass structure, half-cut cell design, and PID/LID-resistant cell technology, these panels ensure durability and long-term performance. They maintain stable energy generation even under low-irradiance conditions, reducing the return-on-investment period.

In addition, the modules are backed by a manufacturer’s warranty of up to 30 years, offering long-term reliability and investment confidence.

2. Inverters

Smart and Uninterrupted Power Conversion

Inverters convert the direct current (DC) generated by solar panels into alternating current (AC) suitable for grid or facility use, effectively serving as the “heart” of the system. High efficiency, multiple MPPT tracking, advanced communication, and protection features directly influence overall performance.

Dev Marmara integrates both string and central inverter solutions, supported by remote monitoring and SCADA integration for real-time system tracking. Full grid compliance, low harmonic distortion, and long warranty periods make these devices reliable and efficient choices for all scales of PV installations.

Depending on the project requirements, on-grid (grid-tied) inverters are used to synchronize production with the utility network, enabling energy export and self-consumption optimization. In off-grid or hybrid systems, stand-alone invertersoperate independently, providing power through integrated battery storage or backup generators — ensuring uninterrupted supply even in remote areas.

3. Mounting and Structural Systems

Safe, Durable, and Tailor-made for Each Roof Type

Mounting and support systems secure solar panels on rooftops, ground surfaces, or carports, forming the foundation of a durable installation. Aluminum and galvanized steel profiles provide high resistance to wind and snow loads.

Dev Marmara carries out project-specific engineering to select the most suitable mounting systems and connection details, considering structural analysis, waterproofing, and maintenance access.

For flat roofs, ballast-type or low-tilt structures reduce roof load and maximize energy yield without penetrating the surface. In membrane roof systems, non-invasive clamps and compatible mounting methods protect the waterproof layer and maintain the roofing warranty.

For sandwich panel and trapezoidal roofs, engineered brackets ensure secure load transfer without damaging the surface. Standing seam and tile roofs use non-penetrative clamps and adjustable hooks to preserve waterproofing while ensuring stable, visually consistent installations.

This approach guarantees a safe, long-lasting, and aesthetically uniform solar infrastructure.

4. Solar Cables and Components

Reliable Transmission, Minimum Loss, Maximum Safety

For energy transmission in PV systems, H1Z2Z2-K solar cables are employed. These cables provide high temperature resistance and excellent UV and ozone protection, ensuring long-term reliability in outdoor conditions. Their double insulation, flame-retardant, and halogen-free composition enhances fire safety and minimizes power losses.

On the alternating current side, Dev Marmara prefer N2XH-type AC power cables. These halogen-free, low-smoke cables offer high dielectric strength and extended service life, making them a safe and efficient choice for building and industrial applications.

All connection components — including MC4 connectors, DC combiner boxes, fuses, breakers, grounding, and lightning protection systems — are selected in compliance with relevant standards to ensure performance and long-term reliability.

5. AC Boards and Power Distribution

Secure, Controlled, and Integrated Power Management

AC boards manage power distribution, protection, and monitoring functions within the electrical infrastructure of solar power systems. They include switchgear, measuring instruments, protection relays, and automation components that ensure safe energy flow and full grid compliance.

Dev Marmara designs project-specific configurations — including AC/DC distribution boards, medium-voltage switchgear, and metering systems — to provide efficient and reliable operation.

All boards are fully integrated with SCADA systems, allowing remote control, real-time data acquisition, and performance reporting. This ensures both operational safety and long-term reliability across all project scales.

6. Smart Energy Management

Real-Time Monitoring, Safe and Smart Operation

Modern solar power plants require intelligent monitoring infrastructure to ensure continuous production and operational safety. Inverters, energy analyzers, and data acquisition units enable real-time performance tracking.

AI-supported software provides production forecasting, fault detection, and performance reporting. In addition, leakage current monitoring, surge protection, and fire safety systems ensure operational continuity and long-term reliability.

Energy generation, consumption, and grid export values are continuously measured and recorded through advanced metering systems. The collected data are analyzed on a daily, monthly, and yearly basis to generate detailed performance and efficiency reports. This enables investors to monitor production trends, detect potential losses, and manage maintenance needs through comprehensive digital dashboards.
