400W Bifacial Solar Panel 2-Pack 200W N-Type 18BB High Efficiency Modules for RV Off-Grid Systems
Two powerful modules provide expanded solar capability
The 400W Bifacial Solar Panel includes two 200W N-Type monocrystalline solar panels, delivering a combined 400W rated output. Built with premium N-Type A+ Grade cells and 18BB silver busbar technology, the system achieves up to 25.2% efficiency for stable solar conversion.
The bifacial structure allows both panels to capture sunlight from the front and rear sides, helping increase energy production under suitable reflective conditions. This design provides an efficient solution for RVs, rooftops, boats, and outdoor off-grid systems.
High-efficiency technology improves power stability
Each 200W module uses advanced N-Type cells designed to reduce resistance and minimize micro-crack risks. The 18BB busbar structure improves electrical performance while supporting stable power output during long-term use.
The panels feature low degradation performance with ≤1% power loss during the first year and ≤0.4% annual degradation, helping maintain reliable solar generation throughout the service life.
Durable construction protects against outdoor conditions
The solar panels are equipped with IP68 waterproof junction boxes and connectors using advanced potting technology. The sealed structure helps prevent water, steam, and dust from entering internal components.
The 3.2mm tempered glass surface, corrosion-resistant aluminum frame, and heat-dissipating junction box design provide additional protection for outdoor environments and long-term installation.
Compact installation design supports flexible placement
The 2-pack 200W configuration provides higher total output while keeping installation flexibility. Each panel includes pre-drilled mounting holes for faster setup with different mounting methods such as Z-shaped brackets, angled brackets, and upright pole mounts.
With a compact module size of 52.76 × 26.38 × 1.2 inches, the panels are designed for Class B vans, RV rooftops, marine systems, and other applications with limited space.
