About Trina Solar

Founded in 1997, Trina Solar Co., Ltd. is a global pioneer and leading provider of smart solar energy solutions. 

Trina Solar has consistently set industry benchmarks, breaking numerous world records for solar cell efficiency and module power output. 

What makes N-Type panels superior to older P-Type panels? N-Type cells use a different doping process (phosphorus instead of boron), which gives them several advantages:

  • Higher Efficiency: They generally convert more sunlight into electricity.

  • Lower Degradation: They are significantly less prone to Light-Induced Degradation (LID) and Potential Induced Degradation (PID), ensuring more stable power output over their lifespan.

  • Better Temperature Performance: They lose less efficiency in high temperatures.
