LG MonoX solar panel frame

Durable Anodized Aluminium Frame

The anodized frames of LG Mono X Plus lengthen the solar panel's lifecycle by forming thick and dense oxide (SiO2) and protecting modules from electrochemically detrimental factors.

Frame Binding with Screw

Screws are used in the assembly of all LG Mono X® Plus frames, exposing the modules to a much lower risk of physical damage. Most panels on the market today use a corner-key type assembly (without screws) leaving the panels vulnerable to further damage from external pressures.

Enhanced Water Drain Design

MonoX panel frame water drain design

LG Mono X® Plus modules have 4 capillary drains in each front corner, liquid sliding design between the front glass and frame, and 12 rear drain holes.

LG Mono X Plus Warranty

25 Year Performance Warranty

LG Mono X® Plus provides a 25 year enhanced performance 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. from previous models.

Mono X Plus certifications

12 Year Product Warranty

In addition to the enhanced performance warranty, LG has a product warranty for LG Mono X® Plus of 12 years.

LG Solar Mono-X Plus LG290S1C-A5 Solar Panel Details

The durable Mono X Plus A5 Series is designed to withstand the elements longer with new features:

Improved Frame Design

The black cell color compliments the glossy piano black anodized frame with clear coating. The quality is apparent with its soft and safe edges. The black screw matches the frame color and provides an accurate fit for assembling between the short and long frames. This careful design leads to a lighweight module with better grips for easy installation.

LG MonoX solar panel review

Outstanding Durability

LG Mono X® Plus modules endure a pressure load of 100 lb which is equivalent to a pile of snow higher than 1.8 meters (weighing more than 1920 lb). Ensuring durability against wind load, the rear of LG Mono X® Plus frame withstands pressure of 100 lb, which is equivalent to a wind speed of 208 mph.

Reduced LID (LiLY Technology)

LG Mono X Plus 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.

Aesthetic Roof

LG Mono X Plus may increase the house value with its shiny black frames. Also, it looks similar to all-black module from a long distance.

Light and Convenient

LG Mono X is carefully designed to benefit installers by allowing quick installation with a weight of just 17kg and better grips.

Ultra Stable Physical Durability

LG Mono X Plus modules are designed to endure a pressure load of 100 lb which is equivalent to a pile of snow higher than 1.8 meters (weighing more than 1920 lb). In order to ensure durability against wind load, the rear of LG Mono X Plus frame is also designed to endure a pressure of 100 lb, which is equivalent to a wind speed of 208 mph.

Lower Dust Level Manufacturing Environment

The LG Solar production site achieved Class 10,000: This is close to lower dust environment and can only be achieved when a dimension of 1ft³ contains less than 10,000 pieces of debris.
