Taekmo 640W Bifacial Solar Panel

Taekmo 640W N-Type Bifacial Solar Panel

The Taekmo 640W Bifacial Solar Panel is a high-performance solar module from the TKM9D72B series, developed for residential, commercial, industrial, and large-scale solar installations. It combines advanced N-Type TBC back-contact cell technology with a robust bifacial double-glass design to deliver high energy yield, strong durability, and reliable long-term operation.

At Standard Test Conditions, the 640W variant provides 640W maximum power output with 23.7% module efficiency, making it suitable for projects where higher power generation and efficient use of available installation space are important.

Advanced N-Type TBC Back Contact Technology

The TKM9D72B series uses N-Type TBC cell technology with a back-contact module design. This architecture supports high conversion efficiency, greater power density, and a clean visual appearance.

Taekmo also highlights partial shading optimisation, which is intended to help the module maintain productive energy generation when part of the panel experiences temporary shading.

Bifacial Double-Glass Design

The Taekmo 640W N-Type Bifacial Solar Panel features a durable dual-glass construction consisting of:

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

The manufacturer specifies a bifaciality factor of 70% ±5%. Under suitable installation conditions, the rear side of the module can utilize reflected sunlight and contribute additional energy generation.

This bifacial design makes the panel particularly suitable for installations where rear-side irradiance can be effectively utilized.
