ERDM Solar 405W Bifacial Monocrystalline Solar Panel
Model 405W | Monocrystalline | 108 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The ERDM Solar 405W is a high-performance bifacial solar panel designed for dependable energy generation. It uses monocrystalline technology with 108 half-cells for strong output and stable operation. The module reaches 405Wp under standard test conditions and delivers an efficiency of 20.72%. Its compact 1724 x 1134 x 30 mm format supports efficient installation across residential and commercial systems. The panel is built for long service life, with a 10-year power warranty and extended linear performance values through 30 years. It is also engineered for harsh environments, low-light performance, and strong mechanical durability.
Key Benefits
High Output Performance: The panel delivers up to 405Wp for reliable daily energy production.
Bifacial Design: Rear-side generation helps improve total energy harvest in suitable installations.
Strong Efficiency: A module efficiency of 20.72% supports better power density in limited roof space.
Durable Construction: An aluminum frame, IP68 junction box, and MC4 connector improve long-term reliability.
Low-Light Advantage: The module is designed to maintain stronger output during cloudy or early-morning conditions.
Weather Resistance: Salt spray and ammonia testing support use in demanding outdoor environments.
How It Works
This solar panel converts sunlight into direct current electricity through monocrystalline silicon cells. The 108 half-cell layout helps reduce internal resistance and supports more stable power delivery. Bifacial construction allows the module to capture reflected light from the rear side. That can increase energy output in installations with bright ground surfaces. The panel is also designed to perform under changing weather conditions, which helps preserve generation across the day. Its temperature characteristics and durable build support consistent operation over many years.
Monocrystalline Cell Conversion: Sunlight strikes the high-efficiency cells and creates usable electrical current. The cell structure supports strong conversion efficiency and stable module performance.
Half-Cell Electrical Design: The half-cell configuration lowers resistive losses and improves current handling. It also supports better output under partial shading conditions.
Bifacial Energy Capture: The rear side can absorb reflected sunlight from surrounding surfaces. This helps increase total system yield in the right installation environment.
