📖 Product Details
Advanced TOPCon BC Technology
The UE485B-54HBD utilizes cutting-edge Back Contact (BC) cell technology. By moving the metal contacts to the rear of the cell, we eliminate front-side shading, resulting in higher current generation, better temperature coefficients, and outstanding performance even when partially shaded.
Bifacial Double-Glass Design
Built with 2.0mm + 2.0mm coated semi-tempered glass on both sides, this module is highly resistant to harsh environmental conditions, including PID, salt mist, and ammonia. The double-glass structure significantly reduces micro-crack risks during transportation and installation, while the transparent backside allows for extra power generation from ground reflection (albedo).
Engineered for Maximum ROI
With a power tolerance of 0 to +3%, you are guaranteed to get the power you pay for. The lightweight (24.3kg) and compact design (1757×1134×30mm) reduce shipping costs (962 pcs per 40' HC) and make installation faster and safer.
💡 Core Selling Points
- 🚀 Ultra-High Efficiency: Up to 24.3% module efficiency and 485W maximum power, maximizing energy yield in limited spaces.
- ☀️ Bifacial Power Gain: Dual glass design with a 70±5% bifaciality factor generates extra power from rear-side reflected irradiance.
- 🌗 Partial Shading Optimization: Advanced BC technology offers better performance under shading conditions compared to traditional modules.
- 🛡️ Extreme Durability: Micro-crack resistance and 2.0+2.0mm coated semi-tempered glass ensure long-term reliability. Passed 25mm hailstone test at 23m/s.
- 📉 Better Temperature Coefficient: -0.26%/℃ Pmax temperature coefficient ensures higher power output in high-temperature environments.
- 💰 Lower BOS Costs: Higher power density means fewer modules, less mounting hardware, and lower balance-of-system costs.
- 🎨 Aesthetic Value: Sleek black anodized aluminum frame and uniform black back sheet for a premium visual appearance.
- ⏳ Superior Warranty: 15-year materials warranty and 30-year power warranty (First year 99.00%, ≤0.38% annual degradation).
