LG solar panel review

LG are a relative newcomer to solar panel manufacturing and shrewdly decided that the mainstream market was already over-crowded with huge brands, so went for the premium market instead. More profitable for all concerned.

We have installed quite a lot of the Neon2 range and a smaller number of the more expensive NeonR range and can say that they are as good as any other quality panels we have ever installed. Not only are the Neon 2 panels quite beautiful (Neon R less so) but the roof top space efficiency is exceptionally good with a 335W Neon 2 or a 365W Neon R taking up the same roof area as a regular 275W panel.

Are they worth the extra money? You can never make a case for LG panels on a cost basis alone, and especially if you are a typical Aussie home owner and will upgrade to a bigger better home within 10-15 years, but if you have anchored down for ever then, yes, they probably are worth considering if only for a set and forget mindset...but don't forget to wash them regularly otherwise your investment is diminished by 5% a year at least.

Do 6kW of LG panels make more power than 6kW of any other monocrystalline panel?

No. Annually they both make the same, and no more than 0-3% more power than a polycrystalline panel either.

Will the cells inside degrade slower than another quality panel ?

Why should they? Their performance warranty, and for what any performance warranty is really worth, is fractionally better than most.

We understand that Whirlpool Greentech forum is awash with LG fans. Many selling them, and others singing their praises after buying them and trying to justify their expensive purchasing decision. We sit on the fence. We've run the numbers on LG and they do what they say they will do, no more no less, same as any other quality panel but they don't out-perform any others in any measurable meaningful way. They are a REALLY nice panel in a sea of mediocrity, but even the humblest Tier 1 panel made today is still a much better than 99.9% chance of performing without the slightest hiccup for 30 years.

Don't buy an LG panel for beating shade!! (Or an Sunpower or REC panel for that matter). Stick a simple $80 Tigo or Huawei optimiser on the panel that gets shade for a FAR better result. FAR means like 10 times better result at least.

Do they work better in the heat or low light? Well yes, the NeonR really DOES. The Neon2 not to any significant degree. Is that extra power from the NeonR worth the investment? Does 1-3% more power on 6kW of panels justify it? You do the maths.


LG NeonR 360W - 60 monocrystalline cells. 1700mm x 1016mm x 42mm

Voltage 36.5V x Current 9.87A = 360W

Price $562 ($1.56 per watt)
Power loss on 30C day = 0.3 x 25 = 7.5%

Power loss on 40°C day = 0.3 x 35 = 10.5%

LG Neon2 330W - 60 monocrystalline cells. 1686mm x 1016mm x 40mm

Voltage 33.7V x Current 9.8A = 330W

Price $400 ($1.21 per watt)
Power loss on 30C day = 0.37 x 25 = 9.25%

Power loss on 40°C day = 0.37 x 35 = 12.95%

LG X Plus 300W - 60 monocrystalline cells. 1686mm x 1016mm x 40mm

Voltage 31.67V x Current 8.84A = 280W

Price $329 ($1.10 per watt)
Power loss on 30°C day = 0.41 x 25 = 10%

Power loss on 40°C day = 0.41 x 35 = 14.35%
