📖 Product Details
The 132 Half-Cell Giant for Utility-Scale Dominance
The UE670B-66HBD BC PV Panel is the ultimate tool for EPCs and developers looking to maximize ROI on massive tracts of land. By utilizing 132 (66×2) large-format 182*210mm cells, we have expanded the module dimension to 2382×1134×30mm, unlocking a colossal 670W output. Fewer modules mean faster installation, less racking, and dramatically reduced labor costs on site.
Unprecedented 75% Bifacial Gain
Featuring an upgraded dual-glass structure with a 75±5% bifaciality ratio, this module outperforms standard bifacial panels. When mounted on trackers or elevated structures over highly reflective surfaces (albedo), the rear side captures more scattered light, pushing the effective power output up to 732W (BNPI).
Built for Extreme Environments
Constructed with dual 2.0mm semi-tempered glass, IP68-rated junction boxes, and a robust anodized aluminum frame, this module is highly resistant to PID, salt mist, and ammonia. The double-glass design inherently prevents micro-cracks during transportation and installation, ensuring a 30-year operational lifespan in the world's harshest climates.
💡 Core Selling Points
- 👑 Absolute Flagship Power: A staggering 670W maximum output drastically reduces the number of modules, combiner boxes, and DC cabling required per MW.
- 💎 Top-Tier 24.8% Efficiency: Harness the power of 182*210mm large-format BC cells for maximum energy density in vast utility-scale arrays.
- ☀️ Unmatched 75% Bifaciality: An upgraded 75±5% bifacial ratio means significantly higher rear-side power generation (up to 732W under BNPI conditions), maximizing yield on reflective grounds like sand, snow, or tracker systems.
- 🌗 Superior Shading Tolerance: The advanced Back Contact (BC) technology eliminates front gridlines, ensuring exceptional performance even in harsh, partially shaded environments.
- 🛡️ Robust Mega-Structure: Built with dual 2.0mm semi-tempered glass and an anodized aluminum frame (32.5kg), passing 25mm hailstone tests at 23m/s and bearing heavy static loads (Front 5400Pa / Back 2400Pa).
- 🚢 Optimized Mega-Logistics: High-density packaging allows 720 pcs per 40' HC container, significantly slashing ocean freight costs per watt compared to conventional panels.
- ⏳ 30-Year Bankability: Backed by a 15-year materials warranty and a 30-year power warranty (First year 99.00%, ≤0.38% annual degradation).
