BC Module 470-500W All-Black Panel - Technical Highlights
| Advantage Point | Technical Highlight | User Benefit / Comparative Value |
| 24.5% Peak Efficiency for High-Density Projects | Adopts advanced GBC back-contact technology, hitting a maximum 24.5% module efficiency with 108-cell (6×18) layout | Reduces module count per MW by ~10% vs. 22% efficiency panels—cuts transportation/storage costs and shrinks installation time for large-scale projects (e.g., 10MW project saves 500+ panels); maximizes power yield for space-constrained commercial rooftops |
| All-Black Aesthetic for Premium Project Bids | Full all-black design: black anodized aluminum frame + 2.0+2.0mm dual glass black surface, matching luxury residential/commercial building exteriors | Enhances project competitiveness in high-end markets (e.g., villa communities, brand retail stores)—differentiates your bids from conventional silver-frame options, helping win contracts with strict aesthetic requirements |
| 70±5% Bifacial Gain vs. Industry Rivals | Bifacial factor of 70±5%, outperforming LONGJI N-type modules’ typical 65% factor; captures reflected light from rooftops/ground | Boosts total project energy yield by 8-15% annually vs. single-sided panels—improves PPA (Power Purchase Agreement) profitability and shortens investor payback periods by 1-2 years |
| Extreme Durability for Low Lifecycle Costs | 5400Pa front/2400Pa rear static load resistance, -40℃~+85℃ operating range, and 25mm hail impact test pass; IP68 junction box resists moisture/corrosion | Eliminates maintenance risks in harsh climates (coastal humidity, high-altitude snow, desert heat)—reduces long-term replacement costs (critical for 25+ year project lifecycles) and avoids costly downtime for repairs |
| 1500V System Voltage & Bulk Packaging Optimization | 1500V maximum system voltage (IEC standard); factory-direct packaging (37 pcs/pallet, 888 pcs/40’ HC) with customized cable length options | Lowers BOS (Balance of System) costs by ~13%—fewer inverters, cables, and racking needed; bulk packaging reduces logistics costs per unit, while customized cables cut on-site modification time for diverse project designs |
| Ultra-Low Degradation for Contract Reliability | ≤1% first-year degradation, ≤0.35% annual degradation, and linear power warranty (meets IEC/CE certifications) | Ensures stable energy output meets pre-signed project contracts (e.g., utility-scale supply agreements)—minimizes penalty risks from underperformance; certified quality supports global distribution (complies with EU, Southeast Asia, and Australian import standards) |
