LG QA System

Operational Excellence

LG PV modules are built on an automated production line in order to maintain the utmost precision and quality.

LG SOLAR USA

Thermal cycling test

To determine the ability of the module to withstand thermal mismatch, fatigue and other stresses caused by repeated changes of temperature.

LG SOLAR USA

Damp heat

To determine the ability of the module to withstand the effects of long-term penetration of humidity.

LG SOLAR USA

Humidity-freeze

To determine the ability of the module to withstand the effects of high temperature and humidity followed by sub-zero temperatures.

LG SOLAR USA

Mechanical load test

To determine the ability of the module to withstand wind, snow, static and ice loads.

LG SOLAR USA

UV preconditioning test

To precondition the module with ultra-violet (UV) radiation prior to the thermal cycle/humidity freeze tests to ensure that those materials and adhesive bonds are less susceptible to UV degradation.

LG SOLAR USA

Hail test

To verify that the module is capable of withstanding the impact of hailstones.

LG SOLAR USA

Salt spray test

To determine the ability of the module to withstand salt water conditions.

LG SOLAR USA

Maximum power test

To determine the maximum power of the module before and after the various environmental tests. Repeatability of the test is the most important factor.

LG SOLAR USA

Module breakage test

To determine the ability of the module to resist heavy stones and other objects that can hit the surface.

LG SOLAR USA

Wet leakage current test

To evaluate the insulation of the module under wet operating conditions and verify that moisture from rain, fog, dew or melted snow does not enter the active parts of the module circuitry, where it might cause corrosion, a ground fault or a safety hazard.

LG SOLAR USA

Insulation test

To ensure that the module is well-insulated between current-carrying parts and the frame.
