LG Solar Power

LG Electronics, Inc. (LG) is a global leader and technology innovator in consumer electronics, mobile communications and home appliances. The company employs more than 84,000 people working in 112 operations, including 81 subsidiaries around the world, with global sales of $55.5 billion in 2009. LG consists of four business units – Home Entertainment, Mobile Communications, Home Appliance, Air Conditioning and Energy Solutions.
LG is one of the world’s leading producers of flat panel TVs, audio and video products, mobile handsets, air conditioners and washing machines.

LG Electronics is also moving one step ahead in the environmentally friendly field of Solar Energy. In 2008, the company proclaimed its charter, ‘Life’s good when it’s green’. LG plans to reduce greenhouse gases in product usage by 30 million tons yearly, and by 150,000 tons by the year 2020.
The company has strictly eliminated usage of harmful substances in its manufacturing processes and its efforts have been recognized by TUV Rheinland of Europe and UL of US. LG’s solar power business has also been launched on the basis of the environment-friendly leadership of LG Electronics.

LG Solar

The history of LG’s solar business can be traced back to the mid-1980’s, when the LG central research lab started R&D on solar technologies. In 2004, the LG business group created synergy and prepared for mass production by consolidating several solar research laboratories under the LG Electronics umbrella. Using decades of R&D experiences, LG Electronics broke ground on its first solar cell and module factory.

LG considers the solar power business not as a mere business expansion, but a new growth engine of the LG Group. A solar industry cluster has been organized within the LG Group and is achieving vertical integration in the solar power industry. Examples include the construction and operation of a 14MW scaled solar power plant in Taean, Korea in 2008 and the supply of wafers through Siltron, a subsidiary company.

Thermal cycling test

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

Damp heat

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

Humidity-freeze

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

Mechanical Load test

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

UV Preconditioning test

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

Hail test

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

Salt Spray test

To determine the ability of the module to withstand salt water condition

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

Module Breakage test

To determine the ability of the module to withstand heavy resistance of stones

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
