TommaTech 450Wp Bifacial N-Type TOPCon Solar Panel TT450-108TNB10 G2G – Wholesale 35 panels per pallet

TT450-108TNB10 is TommaTech's N-Type TOPCon bifacial double-glass module, built on 182.2mm 16BB half-cut mono cells across 108 cells (6x18). Its glass/glass design pairs strong electrical performance with excellent durability, suited to general rooftop and ground-mount installations.

Better light trapping and current collection improve module power output and reliability. N-type cells also have no LID (Light Induced Degradation) by nature, and the module carries IEC 62804 PID certification, helping the panel maintain a strong output curve over its full service life.

Given its compact size and weight, the TT450-108TNB10 efficiency of 23.04% is quite impressive. Bifacial technology enables additional energy harvesting from the rear side of up to 25%, depending on installation conditions. TommaTech backs this module with a 15-year product warranty and a 30-year linear performance warranty guaranteeing at least 87.4% output retention.

• 108 N-Type monocrystalline half-cells (16BB)
• 450 W nameplate capacity
• 23.04% efficiency
• 1500 V DC maximum system voltage
• 0~ 5W positive power tolerance
• 15 years of product warranty and 30 years of linear performance warranty

Higher efficiency of up to 23.04%

TT450-108TNB10 guarantees outstanding power output. N-type TOPCon cell technology combined with self-cleaning, anti-reflection front glass results in 23.04% module efficiency, among the highest in its class.

Better performance at high temperatures

Excellent temperature coefficient means less power loss as temperature rises. Every 1.8°F hike above 77°F will decrease your panel's efficiency by only -0.30%.

High quality standards

Every module is engineered to withstand demanding environmental conditions, guaranteeing the reliability of the solar system. Certifications include IEC 61215, IEC 61730-1/2, IEC 61701 salt mist corrosion, IEC 62716 ammonia corrosion, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, alongside CE compliance.

Low degradation for increased longevity

TommaTech's linear performance warranty guarantees at least 99% of rated power in year one, declining to no less than 93.4% by year 15. After 30 years, the modules will retain more than 87.4% of their initial output.

Certified for standard wind and snow conditions

TT450-108TNB10 is certified to withstand 5400 Pa of snow load and 2400 Pa of wind load. Such resistance is mainly due to the module's double-glass construction, with an IP68-rated junction box ensuring long-term weatherproof performance.
