400W Bifacial Solar Panel 4-Pack N-Type 18BB High Efficiency Modules for RV Marine Applications
Four modules provide scalable solar power options
The 400W Bifacial Solar Panel includes four 100W N-Type monocrystalline solar modules, creating a combined 400W solar power solution. Equipped with advanced 18BB cell technology and up to 25% efficiency, the panels provide reliable energy conversion for outdoor and off-grid applications.
The bifacial structure improves light utilization by capturing available solar energy from different directions. This modular 4-pack design allows flexible installation across RVs, campers, boats, cabins, rooftops, and other 12V solar systems.
N-Type 18BB technology enhances output stability
The solar panels use N-Type monocrystalline cells with an 18BB structure that helps reduce resistance and improve electrical performance. The optimized busbar design helps minimize micro-crack impact and supports stable power generation during long-term operation.
With ≤1% degradation during the first year and 0.4% annual linear degradation, the panels maintain consistent performance for extended outdoor use.
Weather-resistant construction improves durability
Each 100W module is built with IP68 waterproof junction boxes and connectors, helping protect against moisture, dust, and outdoor exposure. The waterproof sealing structure supports reliable operation in different weather environments.
The combination of low-iron tempered photovoltaic glass and anti-corrosion aluminum alloy frames provides additional protection for long-term installation.
Multiple installation options improve system adaptability
The four-panel configuration provides more flexibility compared with a single large module. Each panel includes pre-drilled mounting holes and MC4 connectors, allowing convenient wiring and installation.
Compatible with 12V MPPT and PWM controllers, the 400W system can be integrated into different off-grid setups including recreational vehicles, marine systems, cabins, and rooftop solar applications.
