Product Introduction

This module is built on N-type TOPCon (Tunnel Oxide Passivated Contact) cell technology using 182mm silicon wafers, arranged as 144 half-cut cells in a 72-cell layout. Compared with conventional P-type PERC cells, the N-type substrate has no boron–oxygen complex, which virtually eliminates light-induced degradation (LID) and dramatically reduces potential-induced degradation (PID).

The ultra-thin tunnel oxide layer on the rear surface passivates the contact interface, lifting open-circuit voltage and cutting recombination losses. The result is a higher module efficiency, a gentler temperature coefficient of −0.30%/°C and a markedly better low-light response — so the array keeps producing at dawn, dusk and under overcast skies when P-type modules have already dropped off.

A mono-facial white backsheet construction keeps weight down to 27.5 kg, making this the practical choice for pitched roofs, sheet-metal industrial roofs and any mounting structure where rear-side gain cannot be harvested anyway.

Main Features

N-Type TOPCon cells deliver first-year degradation of only 1% and annual degradation of 0.4%, guaranteeing ≥ 87.4% output after 30 years.
Temperature coefficient of Pmax at −0.30%/°C — roughly 15% less heat loss than P-type PERC, giving higher real-world yield in hot climates.
Half-cut cell design with a 12-busbar layout lowers internal resistive loss and improves shading tolerance.
Excellent low-irradiance performance: stable output at 200 W/m², extending effective generating hours per day.
Anodised aluminium alloy frame with 5400 Pa snow load and 2400 Pa wind load rating; IP68 junction box with three bypass diodes.
Certified to IEC 61215 / IEC 61730, plus salt-mist and ammonia resistance for coastal and agricultural sites.
