Overview

The NKM-132 is a 132-cell N-type bifacial module using 210R wafers, rated from 610 W to 635 W with efficiency up to 23.5%. SMBB technology improves light trapping and current collection, while Hot 2.0 technology gives better reliability and lower LID/LeTID. It performs strongly in weak light such as cloudy days, mornings and evenings, and is certified for extreme wind (2400 Pa) and snow (5400 Pa) loads. Higher bifaciality lowers the levelised cost of energy and balance-of-system cost. Backed by a 12-year product warranty and a 30-year linear power warranty with 0.4% annual degradation.

  • SMBB Technology

    Better light trapping and current collection improve power output and reliability.

  • Hot 2.0 Technology

    N-type cells with Hot 2.0 have better reliability and lower LID/LeTID.

  • Excellent weak-light performance

    More output in cloudy weather, mornings and evenings.

  • Extended wind and snow load tests

    Certified to withstand 2400 Pa wind and 5400 Pa snow loads.

  • Anti-PID

    Excellent PID resistance through optimised production and materials control.

  • Lower LCOE

    Higher bifaciality means more output and lower balance-of-system cost.

FAQ

The panel produces power from its rear side too, using light reflected from the roof or ground. That adds extra output over a standard panel.

Roughly, a 5 kW system needs 8 panels of 635 W. Our team can size a system around your bills and roof.

They carry a 12-year product warranty and a 30-year linear power warranty, with about 87.4% of rated power guaranteed in year 30.
