Trina Solar TSM-NEG9RC.27 - Bifacial solar module for maximum yields

The Trina Solar TSM-NEG9RC.27 from the Vertex S+ series is a bifacial solar module that achieves particularly high efficiency thanks to its n-type i-TOPCon technology. The additional energy generation via the rear increases the yield and is ideal for residential and commercial installations with limited space.

The glass-glass construction ensures increased resistance to weathering, mechanical stress and UV radiation. As a result, the module offers a particularly long service life and high yields over decades

Trina Solar TSM-NEG9RC.27 - High performance bifacial module with dual glass technology


The Trina Solar TSM-NEG9RC.27 from the Vertex S+ series combines n-type i-TOPCon technology with a bifacial glass-glass construction for maximum efficiency and durability. With an output of up to 445 W and a high module efficiency of 22.3 %, it offers outstanding energy yield. Thanks to the transparent backside, the bifacial technology increases power production by up to 85% across the backside - ideal for residential and commercial rooftops that demand maximum performance.


Why the Trina Solar TSM-NEG9RC.27?


  • Powerful with up to 445 W and a high efficiency of 22.3 % for maximum area utilization.
  • Bifacial glass-glass construction for additional energy harvesting through the back.
  • Optimized for high temperatures thanks to a low temperature coefficient of -0.29 %/°C.
  • High resistance with 5,400 Pa snow load and 4,000 Pa wind load.
  • Durable technology with a 25-year product guarantee and 30-year performance guarantee.
  • Compatible with modern inverters and mounting systems, ideal for flexible installations.

Comparison with other high-performance modules


The Trina Solar TSM-NEG9RC.27 offers an excellent combination of performance, durability and additional bifacial energy generation - but how does it compare to other modules?

  • LONGi LR5-54HTH relies on a classic glass-foil construction, while the Trina module delivers higher yields through bifacial technology.
  • Aiko MAH54Mb convinces with ABC cell technology, but does not offer a bifacial function for additional electricity yield.
  • Canadian Solar CS7N-AG is also a bifacial glass-glass module, but achieves a slightly higher maximum output for large systems, while the Trina module is optimized for compact roof surfaces.
While LONGi relies on proven cell technology and Aiko scores with innovative ABC cells, the Trina TSM-NEG9RC.27 offers an ideal solution for long-term energy yields with its bifacial glass-glass construction and high mechanical resilience.


Long-term investment security


  • 25-year product guarantee for top quality and workmanship.
  • 30-year performance guarantee with a maximum of 0.4 % annual degradation.
  • Certified to IEC 61215, IEC 61730 and other international standards.

Conclusion - More power through bifacial glass-glass technology


The Trina Solar TSM-NEG9RC.27 combines n-type i-TOPCon cells with a robust glass-glass construction for maximum durability and high energy yields. Whether for residential or commercial rooftops, this module is a powerful and sustainable choice for long-term power generation.
