Extraordinary N-type Solar Panel
575W Solar Panel, 22.26% Ultra-high Eff

Comparing with PERC solar panel, TOPCon solar panel based on N-type Silicon wafer, have longer lifetime, lower degradation and higher potential of efficiency enhance. 430w TOPCon solar panel’s efficiency up to22.02%, 575w TOPCon solar panel’s efficiency up to 22.26%.

16BB Super-MBB Technology
Half cell Technology

Sunket TOPCon Solar Panel adopts 16-busbar technology. More busbars of the cell decrease the current transverse propagation path by 50%, effectively reduce the internal loss, and improve power of solar panels.

The half-cut cell design can decrease the power loss by the shadow effectively. The optimized circuit design not only realizes the maximum power output but also assures the reliability of solar panels.

First Year Degradation ≤ 1%
-0.4% Linear Degradation

Comparing with PERC solar panel, TOPCon solar panel first year degradation is less than. After 30 years of certification, the output power is not less than 87.40% of the original output power.

-0.30%/℃ Optimized Temp Coeff
Excellent weak light performance

Sunket TOPCon solar panel has Excellent weak light performance. When under the cloudy, haze condition,weak light performance help get more production.

The temperature coefficient of PERC solar panel is -0.35%/℃, TOPCon solar panel is -0.30%/℃. A temperature coefficient rating of -0.30%/℃, Support TOPCon solar panels to generate up to 2% more power than PERC solar panels at high temperatures.


Sunket TOPCon solar panel use N-type solar cell technology,result in extremely low LID/LETID, which supports reliability and longevity. Supports more power generation than PERC solar panel.
