Best solar panel LG vs Best solar panel JA: By A1SolarStore

What are the best panels made by LG and JA Solar? Let’s compare a couple of models by two brands side by side.

LG NeON H series

LG H series panels are designed for small commercial or large residential systems. Here is a panel with 450 watt output and 20.5% efficiency. It features a half-cut cell design for better shading tolerance. The panel has 144 half-cut N-type cells and retains over 90% of its output after 25 years.

JA Solar 405W 144 Cell

The panel provides 405 Watts of power output and reaches a 20.2% energy conversion rate. Half-cut cells make the panel sturdier and increase shading resistance. The busbars improve electricity flow and PERC technology brings efficiency up while keeping production costs low. The design is pretty generic, but again it is made to provide lots of power, not to look good.
