Thornova launches 720-W TOPCon solar module

Thornova Solar is launching a new TOPCon module series exclusively for utility-scale projects. Based on the larger format G12 silicon wafers, the TS-BGT66 and TS-BWT66 modules offer power outputs ranging from 695 to 720 W, with conversion efficiencies from 22.4% to 23.2%.

Thornova offers a 15-year product warranty and a 30-year performance guarantee on modules coming from its Vietnam manufacturing facility.

Thornova G12 series 720-W modules leverage the core advantages of Thornova TOPCon modules in terms of higher efficiency, power output, and reliability. N-type solar cells, devoid of boron-oxygen pairs, virtually eliminate Light Induced Degradation (LID) when compared to PERC solar cells, resulting in a remarkable reduction of power attenuation to approximately 0.15% in Thornova 720-W modules, significantly lower than the 1.35% attenuation seen in PERC modules.

The TS-BGT66-G12 is a bifacial, dual-glass module, weighing 84.88 lbs (38.5kg). With 2.0-mm heat-strengthened glass, anti-reflective coating and another 2.0-mm glass layer at the back, it features an open-circuit voltage between 47.23 V and 47.98 V, and a short-circuit current of 18.68 A to 18.79 A.

TS-BWT66-G12 is a bifacial, single-glass module with transparent white mesh backsheet. Weighing 74.74 lbs (33.9kg), the module includes 3.2-mm of anti-reflective coating and high transmittance, tempered glass, featuring an open-circuit voltage between 46.48 V and 46.73 V, and a short-circuit current of 18.68 A to 18.98 A.

Both modules measure 2,384 mm x 1,303 mm x 35 mm. The temperature coefficient is -0.29% per degree Celsius. They can operate with a system voltage of 1,500 V and function well in a variety of climates, with temperatures ranging between -40°C and 85°C. Annual linear degradation over 30 years is 0.4%, with a maximum degradation in the first year of 1.0%.
