Product Details
Key Features
High Power Output: Each panel delivers a rated maximum power of 445W, providing strong energy generation per square meter.
Superior Module Efficiency: With a module efficiency of 21.0%, the panel converts sunlight to electricity more effectively than many conventional panels.
Bifacial Design: The 70 ± 5% bifaciality captures additional sunlight from the rear side, boosting overall yield especially on reflective surfaces.
Robust Voltage Characteristics: Open circuit voltage of 49.4V and voltage at maximum power of 41.2V ensure compatibility with a wide range of inverters and system designs.
Strong Mechanical Load Capacity: Designed to withstand 5400 Pa on the front and 2400 Pa on the rear, the panel resists wind and snow loads for reliable long‑term operation.
Wide Operating Temperature Range: Operates safely from -40°C to +85°C, making it suitable for Bangladesh’s hot climate and cooler winter nights.
High System Voltage Compatibility: Supports a maximum system voltage of 1500V DC, allowing larger string configurations and reduced balance‑of‑system costs.
Safe Fuse Rating: Maximum series fuse rating of 25A provides built‑in protection against over‑current conditions.
Compact and Lightweight: Dimensions of 2094×1038×35 mm and a weight of 27.5 kg make installation easier on rooftops and mounting structures.
Long-Term Reliability: The panel’s robust construction and high-quality cells ensure stable performance over decades of operation.
