When you buy solar panels, you want to be confident they’ll produce the power you need — now and for decades to come. You also want to be sure they’ll stand up to both normal and challenging weather conditions.
At LG, we make sure you can count on our solar panels. Before our panels are distributed, they undergo a broad range of tests for durability and the quality of their power production. Our solar products meet stringent requirements so that you can be confident in your purchase and satisfied you’ll get a solid return on your investment. And we back that confidence with a 25-year limited product, performance, and labor warranty (up to $450 of labor costs are covered in the rare case that a panel needs to be repaired or replaced).
All LG solar panel tests take place in our own in-house testing laboratory, which is certified by TUV Rheinland and Underwriters Laboratories. LG testing satisfies international requirements for solar panel test procedures.
Below are some of the tests LG solar panels have to pass.
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.
Material Test
In order to eliminate premature material fatigue, our products are tested for their weather resistance in wet and cold conditions.
Mechanical Load Test
Solar panels must demonstrate considerable resistance to mechanical loads. A sophisticated mechanical load test monitors whether LG solar panels can resist adverse conditions such as wind, snow and ice.
Hail Test
Solar panels have to be built to withstand hail. In LG’s hail test, balls of ice are fired at the panels. Then their performance is checked to ensure full functionality.
Flammability Test
The flammability test is designed to determine the ability of each solar panel to withstand fire or fire hazards.
Climatic Test with Solar Irradiance
This test was developed to determine a solar panel’s performance after prolonged exposure to open air conditions.
Module Breakage Test
Stone chips, in particular, are a natural enemy of solar panels. LG’s module breakage test examines the panels’ resistance to stones and other objects that might hit the surface.
Maximum Output Test
After undergoing the various “environmental impact tests,” each solar panel is subjected to a maximum output test. The panel must consistently reach maximum output to pass this test.
If you want to check out how some of these tests work, videos showing the Module Breakage Test, Mechanical Load Test, Hail Test, Flammability Test and Climatic Test are available on LG Solar USA’s YouTube page.
