High Efficiency LG Mono X® 72cell Module Cells: 6 x 12 Module efficiency 17.4% Connector Type: MC4

  • LG340S2W-G4

Key Features

  • Reduced LID (LiLY Technology)
  • Enhanced Performance Warranty
  • Light and Convenient

Enhanced Performance Warranty

LG Mono X® 72cell comes with the enhanced performance limited warranty. The initial degradation has been improved from -3% to -2%, and the annual degradation has also changed from -0.7%/yr to -0.6%/yr.

Reduced LID (LiLY Technology)

LG Mono X® 72cell has improved the initial degradation by applying LG’s new LiLY(LID-improvement for Lifetime Yield) Technology, which controls formation of Boron-Oxygen pair, the key factor of LID.

Improved Product Warranty

In addition to the enhanced performance limited warranty, LG has extended the limited product warranty of LG Mono X® 72cell for additional 2 years with its newly reinforced frame design.

Light and Convenient

LG Mono X® 72cell is carefully designed to benefit installers by allowing quick installation with a weight of just 44.75 lb. and better grips.

Convenient Installation

LG modules are carefully designed to benefit installers by allowing quick and easy installations throughout the carrying,grounding, and connecting stages of modules.
