📖 Product Details
Next-Generation TOPCon BC Technology
The UE500B-54HBD BC Solar Panel adopts state-of-the-art Back Contact (BC) cell technology combined with 182mm cells. By moving the metal contacts to the rear of the cell, we completely eliminate front-side shading, resulting in higher current generation, superior temperature coefficients, and outstanding performance even when partially shaded.
Bifacial Double-Glass Construction
Built with 2.0mm + 2.0mm coated semi-tempered glass on both sides, this module offers superior resistance to harsh environmental conditions, including PID, salt mist, and ammonia. The double-glass structure significantly reduces micro-crack risks, ensuring long-term durability. Meanwhile, 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 24.8kg lightweight and 1800×1134×30mm compact design optimize shipping efficiency (888 pcs per 40' HC), making logistics and installation faster and more cost-effective.
💡 Core Selling Points
- 🚀 Peak Power & Efficiency: Up to 500W maximum output and 24.5% module efficiency, generating more energy per square meter.
- ☀️ Bifacial Power Gain: Dual glass design with a 70±5% bifaciality factor captures reflected light from the rear to boost total energy yield.
- 🌗 Superior Shading Tolerance: Advanced BC (Back Contact) technology eliminates front-grid shading, offering better performance under partial shading conditions.
- 🛡️ Micro-Crack Resistance: 2.0+2.0mm coated semi-tempered glass significantly reduces the risk of micro-cracks during transport and installation. Passed 25mm hailstone tests at 23m/s.
- 📉 Excellent Temperature Coefficient: -0.26%/℃ Pmax temperature coefficient ensures stable power output even in high-temperature environments.
- 💰 Lower BOS & LCOE: Higher power density means fewer modules, less mounting hardware, and lower overall system costs.
- 🎨 Premium Aesthetics: Sleek black anodized aluminum frame and uniform appearance, perfect for projects with high visual requirements.
- ⏳ 30-Year Reliability: Backed by a 15-year materials warranty and a 30-year power warranty (First year 99.00%, ≤0.38% annual degradation)
