Manufacturer's Profile

LG Solar is one product category of LG Electronics. LG Electronics is a subsidiary of LG Corporation, a South Korean multinational company. LG Electronics Inc. was established in 1958 and is headquartered in Yeouido-dong, Seoul, South Korea. It has a workforce of over 75,000. In 2017, it announced revenues of $55.4 billion. In 2017, it produced over 2GW of solar panels. LG Electronics is present in about 118 countries, including Nigeria.

LG has won numerous awards for its ultra-efficient technology, design and high industry standards. LG produces all of their solar panels in their own in-house fully automated manufacturing facilities in Gumi, South Korea, and Alabama, United States. With 30 years experience in the solar industry, LG Electronics are now onto their fourth generation panels. In Australia and North America, LG modules although more expensive than other brands, are very popular.


LG Solar’s testing lab is the first manufacturing lab in the solar industry to be certified by all four major certification institutions (TÜV Rheinland, Intertek, Uderwriters Laboratories and DVE).

LG panels are manufactured under an ISO 9001 (Quality Management System) regime, and multiple tests are undertaken to ensure LG panels are designed and built for a 25 year life span under real world conditions of use. LG solar panels are subjected to a wide range of tests before being released into the market. LG performs the following tests on its panels.

  1. Individual Materials: To ensure that LG solar panels function properly in terms of their component interaction, individual parts, such as wafers, ethylene vinyl acetate (EVA) film, glass and backing film, undergo stringent testing.

  2. Material Test: In order to eliminate premature material fatigue, LG tests its panels for their weather resistance in wet and cold conditions.

  3. Mechanical Load Test: LG tests its solar panels for their resistance to mechanical loads. A sophisticated mechanical load test monitors whether LG solar panels can resist adverse conditions such as wind, snow and ice.
