Development Quality, Parts Quality and Product Quality. That's LG's Reliability Q-System
OUR TEST PROCEDURES
Before LG Solar modules go on sale, they must undergo a broad range of specific tests that guarantee the quality of the production. We thereby ensure that our modules meet the most stringent requirements and that you get a return on your investment. All tests are carried out in our own in-house test laboratory, which is certified by the TÜV Rheinland and Underwriters Laboratories and satisfies all the requirements for the latest test procedures. Here you can find a selection of test procedures that our modules have to pass.
In order to eliminate premature material fatigue, our products are regularly tested for their weather resistance in wet and cold conditions and under extreme changes in temperature.
After undergoing various “environmental impact tests”, the module is subjected to a maximum output test. The test is only passed if the maximum output is reached consistently.
Solar modules need to be able to demonstrate considerable resistance: Sophisticated mechanical load tests monitor whether our modules can resist adverse conditions such as wind, snow and ice.
Stone chips, in particular, are a “natural enemy” of the solar module. Our module breakage test examines the modules for their resistance against stones and other objects that can hit the surface.
A hailstorm is a destructive force that solar modules need to withstand at all costs. In our hail test, hailstones made of ice are fired at the modules and a check is then performed for full functionality.
To ensure that the solar modules function properly in terms of their component interaction, individual parts such as wafers, ethylene vinyl acetate film (EVA), glass and backing film are subjected to stringent tests.
