LG Solar Positives

1. LG black frame/black cell looks better than other’s silver frame blue cells

2. LG standard coating is 22 microns thick – others are typically only 10 micron. There may be a
typical maximum of 1 micron per year degradation of coatings

3. LG frame is screwed together at the corners – others are press-fit corners

4. LG use fully automated production with 1/10th of a mm tolerance for soldering internal
connections – others do not have full automation, and some are even hand-soldered, which leads
to inconsistent internal connections and possible future hotspots

5. LG uses a resin-bond process for sealing the edges of the laminate of the glass panel – least
chance of water penetration. Others typically use silicone, which can degrade or is more easily
damaged, therefore admitting moisture, and corrosion of internal connections begins

6. LG moved from a 225W panel in 2011 to a 315W now all on their own research. Only one other
panel type marketed with 2 brand-names have same or larger capacity panel

7. LG has a clear long term strategy which is developing a 350W in late 2016 and 400W down the
track pre 2020 to take advantage of the need for higher efficiency when the electric car and
home charging kicks in and customers need a 10, 15 and 20kW system. LG is also developing a
battery storage system with sister company LGChem

8. LG never went bankrupt – unlike other brands

9. LG has office and staff in Australia that you can ring and speak to – other brands may only have
a small office here, and are able to close their doors almost anytime

10. LG has dealers and distributors right across Australia . Some other brands have distributed only a
few distributers and these are more vulnerable to closure

11. LG won Intersolar PV award in Germany in 2013 with their Neon
