ERDM Solar 620W N-Type Bifacial Solar Panel
Model ERDM 610 M10-78*2 N Type | N-Type | 156 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The ERDM Solar 620W solar panel is built for high-output commercial performance. It uses N-type bifacial technology to capture more usable energy across the front and rear sides. The design supports strong performance in low-light conditions and demanding environments. With a module efficiency of up to 22.38%, this panel is engineered for projects that value reliable yield and long service life. The 156 half-cell layout helps improve power density and system efficiency. Its monocrystalline construction supports consistent generation across varied installation conditions. This model is suitable for utility-scale rooftops, commercial arrays, and large solar farms.
Key Benefits
High power output: Delivers up to 620W for strong energy production in large installations.
N-type bifacial design: Captures sunlight from both sides for improved total generation potential.
Excellent efficiency: Reaches 22.38% module efficiency for better space utilization.
Built for harsh conditions: Passed salt spray and ammonia corrosion testing for improved durability.
Low-light performance: Maintains strong output when sunlight levels are reduced.
Long-term reliability: Includes a 25-year warranty and controlled annual degradation.
How It Works
This ERDM Solar module converts sunlight into electricity through high-efficiency N-type monocrystalline cells. The front surface captures direct irradiance during normal operation. The bifacial structure also gathers reflected light from the rear side. That increases total energy harvest in suitable mounting conditions. The 156 half-cell configuration helps reduce resistive losses and supports stable output. Its temperature coefficients are optimized for hot climates and variable weather. The panel is designed to work with modern high-voltage solar systems. It is well suited to commercial installations that need dependable performance over many years.
N-type cell conversion: The module uses N-type cells to turn sunlight into usable DC electricity. The design supports stronger output retention over time.
Bifacial light capture: The rear side can absorb reflected light from the installation surface. This can improve total generation in reflective environments.
Half-cell electrical layout: The 156 half-cell architecture helps reduce internal losses. It also supports better current handling and system stability.
