Features Technical Indicators Overall Dimension

TOPCon Cell Technology
- Higher Efficiency: ~22.5% (vs. ~21.5% for N-type) due to reduced recombination losses.
- Lower Degradation: <0.3% annual degradation (vs. <0.4% for N-type).
- Superior Temperature Coefficient: -0.28%/°C (vs. -0.30% for N-type) → 1–2% less power loss at high temps.
108 Half-Cell Design
- Compact Configuration: Smaller form factor (assumed 1754mm x 1096mm) → Ideal for residential rooftops.
- Lower Current: ~11A (vs. ~18A for 700W modules) → Simplifies string design.
Bifacial Power Generation
- 5–20% Yield Gain: Maximized with reflective surfaces (e.g., white roofs, light-colored gravel).
- Perfect for carports or commercial rooftops with limited space.
Mechanical Robustness
- 2400Pa Wind / 5400Pa Snow Load: Certified for extreme weather (same as N-type models).
- Thicker front glass (2.0mm) enhances impact resistance.
IP68 Junction Box
- Dustproof/waterproof with 3 bypass diodes → Reliable in humid/coastal environments.
Cost Efficiency
- Lower BOS Costs: Fewer modules per string → reduced cabling/racking expenses.
- LCOE Advantage: +8% energy yield → ~5% lower LCOE vs. conventional 400W modules.

Parameter	Value	Industry Context
Model	ET175N-108D (assumed)	TOPCon bifacial module with 108 half-cut cells. Targets residential/commercial rooftops.
Power Output	435W–455W	Mid-range power class (similar to N-type but with TOPCon advantages).
Cell Technology	TOPCon monocrystalline, 108 half-cells	TOPCon ensures <0.3% annual degradation (better than N-type). Half-cell design reduces resistive losses.
Bifaciality	Double-sided (5–20% rear-side yield gain)	Optimized for elevated installations (e.g., flat roofs, carports).
Cables	300mm length, 4mm² cross-section	Standard for moderate currents (~11A at 440W). 4mm² minimizes voltage drop.
Front Glass	2.0mm high-transparency tempered glass	Double-glass construction ensures durability (30-year lifespan).
Packaging	936 modules per cabinet	Efficient logistics (≈30 metric tons/cabinet, assuming 32kg/module).
