The flagship solar panel of LG Solar is known for its high production and a great efficiency which reaches 21.2%. It has 60 N-type monocrystalline cells which lose less output in their first year in operation and increase conversion rate. NeON 2 had many variants over the years, including bifacial and all-black panels.

Solaria PowerXT-400R-PM

Solaria PowerXT panel provides 400 W power with 20.2% efficiency. the module retains 86% of initial output after 25 years. Shingled design of the panel makes it more resistant to extreme weather conditions and increases shading tolerance. Notice the unconventional size: most 72-cell panels would be around 39" x 77" in dimensions, Solaria panel is instead wider: 47" x 64".
