    TOPCon N-type solar cell-based modules have certain advantages over conventional P-type Mono PERC modules listed as under:

    • A comprehensive table enlisting comparison between P-type PERC and N-type TOPCon Module is included (as under) for a clear understanding of module performance parameters for both technologies.
    • High efficiency and high wattage modules with better performance and reliability.
    • Lower temperature coefficient -0.31 %/°C as compared to Mono PERC modules -0.34%/°C thereby lower temperature losses and higher energy yield.
    • Excellent anti-PID performance.
    • Lower first-year degradation rate around 1% as compared to 2% in p-type Mono PERC modules.
    • Zero LID and lower LeTID losses due to phosphorous doping (no boron-oxygen defects).
    • Lower year-on-year (YOY) degradation rate of -0.4% as compared to -0.55% for Mono PERC modules.
    • A comprehensive table enlisting comparison between P-type PERC and N-type TOPCon Module is included (as under) for a clear understanding of module performance parameters for both technologies.

    WEL offers 12 years product warranty and 30 years performance warranty on N-type TOPCon Bifacial modules. Waaree’s N-type TOPCON modules will result in more energy generation and are the optimal solution in MW scale ground mount PV installations with better ROI.
