    BC Module 655-685W Panel - Technical Highlights

    Advantage PointTechnical HighlightUser Benefit / Comparative Value
    24.5% Efficiency + 156-Cell Layout for MW-Scale DensityAdopts advanced GBC gapless back-contact technology, 24.5% maximum efficiency (0.3% higher than Jinko N-type TOPCon), and 156-cell large-format designCuts module quantity per 100MW project by ~4,200 units vs. 600W-class panels; reduces land occupation by 14% (critical for ground-mount projects with limited acreage) and slashes installation labor costs by 18%
    70±5% Bifacial Gain + 10-15% Yield Surpass Tier 1
    Bifacial factor of 70±5%, 10-15% higher than typical Tier 1 modules—captures rear-side irradiance from ground reflections (gravel/white membranes) or diffused light (overcast regions)
    Adds ~2.5GWh extra annual energy for a 100MW project; shortens investor payback periods by 2.5-3 years, enhancing project competitiveness in PPA bidding
    5400Pa Load + -40℃~+85℃ Climate Versatility5400Pa front/2400Pa rear static load resistance (withstands heavy snow in Northern Europe/Canada), 25mm hail impact resistance, and -40℃~+85℃ operating rangeEliminates downtime risks in extreme climates (Middle East high heat, Southeast Asia humidity); reduces long-term maintenance costs by 35% vs. modules with 4800Pa load ratings
    1500V High Voltage + 30A Fuse for BOS Cost Optimization1500V maximum system voltage (IEC standard) + 30A high-current fuse—supports longer string lengths (up to 32 modules/string)Lowers BOS costs by 20-23%: reduces inverter quantity by 22%, cuts cable/racking usage by 17%, and simplifies system design for large-scale projects
    0~+3% Power Tolerance + IP68 Safety for Contract Reliability0~+3% positive power tolerance (actual output often exceeds rated power) + IP68 junction box (moisture/dust-proof) + IEC Class A fire ratinFulfills strict energy output clauses in utility contracts; meets global safety certifications (CE/IEC/UL), enabling distributors to enter 90+ countries without compliance rework
    ≤0.35% Annual Degradation + 25-Year Linear Warranty≤1% first-year degradation, ≤0.35% annual degradation, and 25-year linear warranty (guarantees 88.85% output after 25 years)Ensures stable performance for 20+ year utility PPAs; avoids underperformance penalties, and provides reliable data for project financing (critical for securing investor funds)
    2465×1134×30mm Standard Size + Bulk PackagingStandardized dimensions (compatible with mainstream racking systems) + bulk packaging (37 pcs/pallet, 888 pcs/40’ HC)Eliminates custom racking costs; 888 units per 40’ HC lowers logistics cost per unit by 15%, boosting distributor profit margins by 6-8%
