REC Solar REC400NP3 400W N-Type TOPCon Bifacial Monocrystalline Solar Panel
REC400NP3 | N-Type TOPCon | 132 Half-Cell | Bifacial | 1000V System Voltage
Product Overview
The REC Solar REC400NP3 400W N-Type TOPCon Bifacial Monocrystalline Solar Panel is a premium choice for modern energy systems. This advanced module delivers 400 watts of peak power with an impressive 20.3% efficiency rating. It features 132 half-cut monocrystalline cells built with cutting-edge N-type TOPCon technology. The all-black design ensures a sleek appearance that blends perfectly with residential roofs or commercial installations. Bifacial capability allows the panel to capture sunlight from both sides, boosting total energy yield significantly. REC Solar Pte. Ltd. manufactures this panel in Singapore with strict quality controls. It operates reliably in extreme temperatures ranging from -40°C to +85°C. The panel includes a robust anodized aluminum frame and anti-reflective glass coating. This product is designed for grid-tie, off-grid, and residential applications worldwide.
Key Benefits
High Power Output: This panel generates 400 Wp of maximum power for efficient energy production.
Superior Efficiency: It achieves a 20.3% module efficiency to maximize sunlight conversion per square meter.
Bifacial Technology: Captures light from both front and rear sides, increasing total effective power by over 12%.
Advanced Cell Tech: N-type TOPCon technology reduces degradation and ensures long-term performance stability.
Durable Construction: Features anti-reflective glass and a black anodized frame for weather resistance and aesthetics.
How It Works
The REC400NP3 solar panel converts sunlight into electricity using advanced photovoltaic principles. Sunlight strikes the 132 half-cut N-type cells, exciting electrons to create an electric current. The bifacial design allows the rear side to capture reflected light from the ground or roof surface. This dual-sided absorption significantly increases the total energy generated compared to standard panels. The N-type TOPCon technology minimizes electron loss and reduces thermal degradation over time. A split-cell junction box design lowers internal resistance and improves current flow efficiency. The anti-reflective glass coating ensures maximum light penetration into the cell structure. This system operates efficiently even in low-light conditions or high-temperature environments.
Photovoltaic Conversion: Sunlight photons hit the silicon cells, releasing electrons to generate direct current electricity. The half-cut cell design reduces resistance and improves power output under partial shading.
Bifacial Energy Gain: The rear side captures albedo light reflected from surfaces below the panel. This adds approximately 50 watts of rear gain, boosting total effective power to 450 watts.
N-Type Stability: N-type cells use a different doping process that prevents light-induced degradation. This ensures the panel maintains over 92% of its original power after 25 years.
