Taekmo 645W Bifacial Solar Panel

Taekmo 645W N-Type Bifacial Solar Panel

The Taekmo 645W Bifacial Solar Panel is a high-power solar module from the TKM9D72B series, designed for residential, commercial, industrial, and utility-scale solar projects. It combines advanced N-Type TBC back-contact cell technology with a durable bifacial double-glass structure for high energy yield, strong mechanical reliability, and long-term solar performance.

At Standard Test Conditions, the 645W variant delivers 645W maximum power output with 23.9% module efficiency. This high power density makes it well suited to projects where maximum electricity generation from available installation space is required.

Advanced N-Type TBC Back Contact Technology

The Taekmo TKM9D72B series uses N-Type TBC cell technology with a back-contact module architecture. This design supports high module efficiency, strong power output, and a cleaner front-side appearance.

The manufacturer also highlights partial shading optimisation, helping improve module performance where temporary or partial shading may occur.

Bifacial Double-Glass Design

The Taekmo 645W N-Type Bifacial Solar Panel features a robust dual-glass construction with:

• 2.0 mm coated semi-tempered front glass
• 2.0 mm semi-tempered back glass

The datasheet specifies a bifaciality factor of 70% ±5%. When installed in suitable conditions, the rear side can utilize reflected sunlight to contribute additional energy generation.

This bifacial configuration can improve total energy yield compared with conventional single-sided solar panels.

High 23.9% Module Efficiency

According to the manufacturer datasheet, the Taekmo 645W model provides the following STC electrical characteristics:

• Maximum Power (Pmax): 645W
