400W Bifacial Solar Panel 4-Pack N-Type 18BB Monocrystalline Modules for 12V Off-Grid Systems
Four-panel design increases solar system flexibility
The 400W Bifacial Solar Panel combines four 100W N-Type monocrystalline solar panels with advanced 18BB cell technology, delivering a total rated power of 400W. With up to 25% cell efficiency, the N-Type solar cells provide improved light absorption and stable energy conversion for various outdoor applications.
The bifacial design helps capture solar energy from different directions, providing flexible installation options for RVs, camper vans, boats, cabins, rooftops, and other off-grid solar systems.
High efficiency cells support consistent power generation
Each 100W panel uses N-Type 18BB solar cells designed to reduce electrical resistance and minimize micro-crack effects. The optimized structure helps maintain stable output with low degradation performance, including ≤1% degradation in the first year and 0.4% yearly linear degradation.
The four-panel configuration provides higher total output while maintaining the advantages of compact individual modules, making system expansion more convenient.
Strong protection design improves outdoor reliability
The 400W Bifacial Solar Panel features IP68 waterproof junction boxes and connectors to protect against water, dust, and moisture. The sealed design helps maintain stable operation under different outdoor conditions.
The panels use 3.2mm low-iron tempered photovoltaic glass and anti-corrosion aluminum alloy frames to improve durability during long-term outdoor installation.
Flexible 12V compatibility simplifies solar integration
The 4-pack 100W solar panel configuration works with 12V MPPT and PWM controllers as well as compatible power stations. MC4 connectors and pre-drilled mounting holes allow easier installation and system connection.
The modular design provides flexible placement options for different applications, including RV solar systems, marine power setups, rooftop installations, and outdoor cabins.
