ERDM Solar 400W Bifacial Monocrystalline Solar Panel
Model 400W | Monocrystalline | 108 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The ERDM Solar 400W Bifacial Monocrystalline Solar Panel is built for dependable performance and long service life. It combines 108 half-cut 182×182 mm cells with a bifacial design for stronger energy capture. The panel is rated at 400 Wp under STC and reaches up to 21.27% efficiency in higher-rated versions. Its aluminium frame, IP68 junction box, and MC4-compatible connectors support reliable installation. The panel is designed for demanding environments, including high wind and snow loads. It is a strong choice for residential and commercial solar projects.
Key Benefits
High Power Output: Delivers 400 Wp at STC, with model options extending to 415 Wp for added generation potential.
Bifacial Energy Gain: The bifacial architecture can capture reflected light from the rear side for improved yield.
Strong Efficiency: Module efficiency ranges from 20.46% to 21.27%, supporting excellent output per square meter.
Durable Construction: An aluminium alloy frame and IP68 junction box support outdoor reliability and weather resistance.
Harsh-Environment Ready: The module is tested for wind loads up to 2400 Pa and snow loads up to 5400 Pa.
How It Works
This solar panel converts sunlight into usable electricity through monocrystalline cells arranged in a half-cell configuration. The cells absorb solar radiation and generate direct current with strong electrical stability. The bifacial build can also use reflected light, which helps increase total energy harvest. The panel then sends power through MC4-compatible cabling for connection to a solar inverter or battery-based system. Its electrical ratings, temperature performance, and protective construction help maintain output across varied operating conditions. This design supports efficient energy production in both standard and challenging environments.
Monocrystalline Cell Conversion: The monocrystalline cells convert sunlight into DC electricity with stable performance. Their 182×182 mm format supports high power density and consistent output.
Bifacial Light Capture: The bifacial structure can collect light from both sides of the module. This increases usable energy when the installation surface reflects sunlight.
System Integration: Power is delivered through MC4-compatible connectors and 4 mm² cable. This simplifies installation and helps ensure secure electrical connection.
