But inside the LG NeON 2, there are almost no B-O pairs. This is why LG NeON 2 has almost no LID*.* LID: Light Induced DegradationWhen micro crack or finger electrode erosion happens by natural degradation of mechanisms in the outskirts of the solar cell,LG NeON 2 reduces down performance by blocking the electrical path due to the tight layout of NeON 2 cell produces energy from both the front and back.

3 By absorbing light from even the backside, the cells raise efficiency. This makes LG NeON 2 cells particularly more efficient than conventional cells in mornings and evenings when the incident angle is NeON 2 / No pair, No LIDC onventional / B-O pair, LIDPO eeeeeeeeeeeeeeeeeeeBO++--eeeeeeeeeeeeLG NeON 2LG NeON Cell'sfingerCell'sfingerCell'sfingerSiNx :HSiOx:H / SiNx:HGlassBacksheetEmitterEmitterEmitte rSiOx:H / SiNx:H5 Compared with conventional multi module with 72 cells , LG NeON 2 achieves higher power output with 60 cells , making it easy to manage space when installing large scale systems. Also, with lower Voc than 72 Cell module, LG NeON 2 increases module quantity per 1 string that decreases the total number of strings which leads to lower NeON 2 reduces the space needed for installation due to its high module efficiency. The size and efficiency of the modules allow users to consider the shadow of physical objects such as trees or a chimney, to get the best possible outcome from a deployment.

Aug) Max speed: 75m/sLG NeON 2 has an enhanced performance warranty. The annual degradation has fallen from to LG has also extended the warranty of the LG NeON 2 for an additional 2 years.* The comparison between the IRR (Internal Rate of Return) was calculated internally at LG to compare the relative return rate between different modules.
