Thornova 440W Tangra™ S Black: N-Type Bifacial High Efficiency

The Thornova 440W TS-BBT54 is a premier N-Type Bifacial module engineered for maximum energy harvest. Part of the Tangra™ S Black series, this panel features advanced N-type solar cells that naturally eliminate LID (Light Induced Degradation). With its bifacial design, you can harvest up to 30% additional energy from the rear side, making it one of the most productive 440W panels for residential and commercial solar arrays.

Advanced N-Type Bifacial Technology

• 30-Year Lifespan: N-type technology offers 10-30% more power generation over its lifetime compared to conventional P-type modules.
• Zero Natural LID: N-type cells are immune to Light Induced Degradation, ensuring higher day-one and long-term performance.
• Market-Leading Thermal Coefficient: Industry-leading low temperature coefficient (-0.30%/°C) means better power output in hot climates.
• Enhanced Light Trapping: Optimized current collection and light trapping contribute to an impressive 22.53% module efficiency.
• Triple EL Tested: 100% triple Electroluminescence testing ensures every panel is free of hidden micro-cracks.
