Waaree N-Type TOPCon: India’s Highly Efficient PV Modules

Reading Time: 3 minutes

Waaree Energies Limited (WEL) is India’s largest solar PV Company with 12GW of annual module manufacturing capacity. WEL strives to provide high-quality and cost-effective energy solutions in the green energy sector. Advanced technology adoption, design, strong process control, flexibility, recycling inception, accelerated performance and reliability testing are the important pillars which has helped Waaree to emerge as a technology leader and a continuous performer (being rated as Tier 1 module manufacturer by Bloomberg NEF since past more than 20 quarters) and the largest PV module manufacturer in India.

WEL is currently manufacturing highly efficient and advanced TOPCon N-type PV modules in M10 and M12 configurations in both Bifacial glass to glass and glass-to-transparent backsheet variants. TOPCon (Tunnel Oxide Passivated Contact) which is considered to be the next generation of solar cell technology consists of the additional tunnel oxide layer and doped poly-Si layer for better passivation and improved performance.

WEL is the first Indian company to manufacture M12 and M10 TOPCon N-type PV modules in India. Waaree’s Elite series (N-type TOPCon) Glass to Glass and Glass to Transparent backsheet 610-630 Wp (120 cells based) and 670-690 Wp (132 cells based) M12 210 mm cell size based MBB Bifacial PV modules offer the highest reliability, enhanced crack tolerance, high power output, best-in-class thermal coefficient of -0.31 %/⁰C, low resistive losses, PID resistant, certified with advanced mechanical load testing and durability testing in extreme climatic conditions.

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.
