Sungrow Solar 630W N-Type Double Glass Bifacial - Silver Composite Frame
The Sungrow SG-66TG4D is a high-efficiency N-type TOPCon solar module engineered for superior performance and durability.
This panel delivers 630W high power output, making it ideal for commercial and large-scale installations.
Its advanced double-glass bifacial design enables energy generation from both the front and rear sides, increasing total energy yield and improving overall system performance.
KEY FEATURES:
- 630W high-power output with module efficiency of 23.3%
- N-type bifacial TOPCon technology
- Silver composite frame - a robust, corrosion-resistant, non-metallic structure reinforced with 78% glass fibre and polymer composite materials
- Cell orientation: 132 (6 x 22)
- Double glass construction with 2.0 mm glass thickness
- Maximum System Voltage: 1,500V
- Bifacial Design: The rear power generation is 20% higher than PERC modules.
- Anti-PID Guarantee: Minimizes the chance of degradation caused by PID phenomena through optimization of cell production technology and material control
- Superior Temperature Coefficient : Generating 1%-2% more power than P-type modules in high temperature regions.
- Superior Low Irradiation Performance: Higher power output in the morning and evening, cloudy days, haze and other low-light scenarios.
- Extended load tests - Heavy snow load up to 5400 Pascal wind load up to 2400 Pascal
- IP68 Rating
- Standard 15 year product warranty; 30-year performance warranty
