400W Bifacial Solar Panel 2-Pack 200W N-Type 18BB Monocrystalline Modules with 25.2% Efficiency
Dual 200W modules deliver higher solar output
The 400W Bifacial Solar Panel combines two 200W N-Type monocrystalline solar panels with advanced 18BB silver busbar technology, providing a total rated output of 400W. With up to 25.2% efficiency, the high-performance N-Type cells deliver stable energy conversion for RVs, rooftops, boats, and off-grid applications.
The bifacial design captures sunlight from both the front and rear sides, helping increase solar energy collection under suitable reflective conditions. This two-panel configuration provides higher power output while maintaining flexible installation options.
Advanced cell structure improves long-term performance
Each 200W panel uses premium N-Type A+ Grade cells combined with 18BB technology to reduce resistance and improve current transmission. The optimized structure helps minimize micro-crack risks and supports stable output during extended operation.
The panels feature low degradation performance with ≤1% degradation in the first year and ≤0.4% annual degradation, helping maintain reliable solar generation over time.
Waterproof protection supports outdoor environments
The 400W solar panel system features IP68-rated waterproof junction boxes and solar connectors with advanced potting technology. The sealed structure helps prevent water, dust, and moisture from reaching internal components.
The corrosion-resistant aluminum frame, 3.2mm tempered glass, and heat-dissipating junction box design improve durability and support stable operation in demanding outdoor conditions.
Flexible mounting design simplifies system installation
The 2-pack 200W solar panel configuration provides a practical solution for larger solar setups while maintaining installation flexibility. Each panel includes pre-drilled mounting holes that support quick installation with Z-shaped brackets, angled brackets, or upright pole mounts.
With a compact size of 52.76 × 26.38 × 1.2 inches per panel, the system is suitable for Class B vans, RV rooftops, marine applications, and other limited installation spaces.
