MonoX™ series are LG Electronics’ high-qualitymonocrystalline module brands. The quality is theresult of our strong commitment to developing amodule to improve benefits for customers. Featuresof MonoX™ series include higher efficiency anddurability, convenient installation, and aestheticexterior.

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

The Extra 2% PowerTo minimize losses due to mismatch, LG produces 3 groups of solar modules which are sorted by its current class. This enables MonoX™ to maximize the system’s output by around 2% based off the theoretical calculation.

Positive Power ToleranceLG provides rigorous quality testing to solar modules to assure customers of the stated power outputs of all modules, with a positive nominal tolerance starting at 0%.

60 cell

Light and RobustWith a weight of just 16.8 kg, LG modules are proven to demonstrate outstanding durability against external pressure up to 5400 Pa.

100% EL Test CompletedAll LG modules pass Electroluminescence inspection. This EL inspection detects cracks and other imperfections unseen by the naked eye.

Reliable WarrantiesLG stands by its products with the strength of a global corporation and sterling warranty policies. LG offers a 10 year product limited warranty and a 25 year limited linear output warranty.

About LG Electronics

LG Electronics is a global big player who has been committed to expanding its capacity, based on solar energy business as its future growth engine. We embarked on a solar energysource research program in 1985, supported by LG Group’s rich experience in semi-conductor, LCD, chemistry, and materials industry. We successfully released the first MonoX™series on the market, in 2010, which were exported to 32 countries in 2 years, thereafter. In 2013, MonoX™ NeON won “Intersolar Award”, which proved it’s the leader of innovation in the industry.
