What effect has Anti Reflective Glass Coating?

LG modules have Anti Reflective Glass Coating. Our production results to date show that standard test condition (STC) flash power gain due to Anti Reflective Coating on glass is on average 2.7%.

After more than three years of outdoor testing in various climates, the energy production gain from ARC glass modules is 3.5-5% depending on the type of installation and location. The higher energy gain as compared to STC flash gain is due to improved coating gain in diffuse and off-angled light due to the effect of the refractive index and the light scattering within the coating.
