• Installation time and labor requirements

• Land/roof space requirements by 15-20% compared to 600W alternatives

2.TOPBiHiKu7 705 watt N-type Bi-facial Canadian  Superior Bifacial Performance

• >90% Bifaciality: Industry-leading rear-side efficiency

• Real-World Gains: 5-30% additional energy yield depending on surface albedo

• Optimal Applications: Elevated ground-mount systems with high-reflectivity surfaces (sandy terrain, white membranes, gravel)

3. N-Type TOPCon Advantages Over PERC

• Lower Degradation: <1% first-year degradation vs. 2% for PERC

• Better Temperature Performance: Maintains higher output at elevated temperatures

• Enhanced Low-Light Response: Superior dawn/dusk and cloudy day performance

• Zero LID (Light-Induced Degradation): Eliminates PERC’s initial power drop

• ROI Impact: 10-15% lower LCOE (Levelized Cost of Energy) over project lifetime

• Temperature Performance: Only 8.7% power loss at 60°C vs. 12% for PERC alternatives

Ideal Applications

Primary Markets:

1. Utility-Scale Solar Farms

   • Large ground-mounted installations (10+ MW)

   • High-albedo environments (desert, coastal, snow-prone regions)

   • Tracking system compatibility (single-axis and dual-axis)

2. Commercial & Industrial Rooftops

   • White membrane roofs (enhanced bifacial gain)

   • Large flat commercial buildings

   • Carport solar structures

3. Specialized Applications

   • Agri-photovoltaic systems (crop-compatible installations)

   • Floating solar farms (water surface enhances bifacial gain)

   • Noise barrier integration along highways

Installation Considerations:

• Mounting: Requires specialized racking for 700W+ class modules

• Spacing: Increased rear-side clearance recommended for optimal bifacial gain

• Electrical Design: Higher current requires compatible string inverters (≥20A input)

• Handling: Two-person minimum recommended due to size/weight

Financial & Environmental Impact

Project Economics

• Reduced BOS Costs: ~$0.05/W reduction in overall system costs

• Increased Energy Yield: 5-30% higher than monofacial equivalents

• Shorter Payback Period: 6-18 months faster ROI compared to standard bifacial

• Land Efficiency: 1.2-1.5 MW/acre achievable (vs. 1.0 MW/acre for 600W panels)

Sustainability Credentials

• Carbon Payback: <1 year (faster than industry average)

• Recyclability: 96% recoverable materials

• Manufacturing: Low-carbon production with renewable energy usage

• Certifications: IEC 61215, IEC 61730, IEC TS 62994 (bifacial), UL 61730
