Cell Technology: 144 Half-Cell Monocrystalline PERC
The panel utilizes advanced Passivated Emitter and Rear Cell (PERC) technology combined with half-cell design to achieve superior performance:
- Enhanced Light Absorption: PERC technology adds a passivation layer to the rear of the cell, reflecting unabsorbed light back through the cell for a second chance at conversion
- Reduced Resistive Losses: Half-cell design cuts current in half while maintaining voltage, significantly reducing power losses
- Improved Shade Tolerance: 144 individual cells with optimized bypass diodes minimize the impact of partial shading
- Better Heat Dissipation: Smaller cell size and improved design reduce operating temperatures
Bifacial Technology Benefits
The panel’s bifacial design allows it to capture sunlight from both front and rear surfaces:
- Front-side Efficiency: 21.2% under standard conditions
- Rear-side Efficiency: Approximately 85% of front-side performance
- Bifacial Gain Range: 5-25% additional power output depending on installation conditions
- Optimal Ground Albedo: Light-colored surfaces (concrete, white gravel) maximize rear-side generation
Physical Construction and Durability
Built for longevity and reliability:
- Frame Material: 30mm anodized aluminum alloy for corrosion resistance
- Glass: High-transmission tempered glass with anti-reflective coating

Bifacial Technology Explained
How Bifacial Solar Panels Work
Unlike traditional monofacial panels that only capture direct sunlight on the front surface, bifacial panels generate electricity from both sides. The rear surface captures reflected and diffused light from the ground and surrounding environment.
The BlueSun 460W achieves this through:
- Transparent Backsheet: Allows light to reach the rear-side cells
- Dual-Glass Construction: Some variants use glass-glass design for enhanced durability
- Optimized Cell Layout: Rear contacts designed to maximize light absorption
Real-World Bifacial Gain Expectations
Actual bifacial gain varies significantly based on installation conditions:
- Ground-Mount Systems: 15-25% gain with optimal ground albedo
- Elevated Installations: 10-20% gain with proper clearance
- Roof-Mount Systems: 5-10% gain depending on roof material and tilt
- Tracking Systems: Up to 30% gain with single-axis trackers
Installation Considerations for Maximum Bifacial Benefit
To optimize bifacial performance:
- Minimum Ground Clearance: 2-3 feet for ground-mount systems
- Optimal Tilt Angle: Lower tilt angles (10-30°) often perform better than latitude-based tilts
- Row Spacing: Increase spacing by 20-30% compared to monofacial installations
- Ground Surface: Light-colored materials like white gravel or concrete maximize reflection
- Avoid Shading: Minimize obstructions that could shade the rear surface
