LG Company Overview

LG Corporation is a multinational electronics company headquartered in Seoul, South Korea, with 50 offices in 48 countries, including Australia. The company was formerly known as Lucky Goldstar but was rebranded as the LG Corporation in 2002, playing on their initials with the tagline “Life’s Good“.

LG has been producing various electronic devices for decades – the company even ranked first in market share of LCD TVs across the world in 2013. The company also offers products in energy storage, heat pumps, air conditioning, and all manner of other electronic appliances. In 2009, the company made its first solar module under the name LG Solar, a subsidiary of LG Corporation.

LG solar panels are produced in their facilities in Gumi, South Korea and Huntsville, Alabama. At a time when the majority of the world’s photovoltaics are made in China, LG proudly assert they don’t believe in outsourcing their manufacturing.

LG Solar is a Bloomberg Tier 1 manufacturer and holds various awards for their ultra-efficient cell technology. The company takes pride in its quality, reliability, and first-class service – and, truth be told, few other solar companies can compete at the same level.

LG Solar Features in Australia

Most manufacturers produce a range of the more common P-type monocrystalline silicon cells, but LG cell technology is taking a different route. The company’s solar panels are composed of N-type cells, which offer higher efficiency and a much lower degradation rate, albeit at a higher price. Still, in order to be more competitive across various market strata, LG recently introduced Mono X Plus, a more affordable range of panels made with P-type cells.

Their latest Neon 2 modules place LG among the leaders in multi-wire cell technology, with 12 round wire busbars and a special finger design implemented in all of their Neon 2 and Neon 2 bifacial solar modules. 

There are two large solar module manufacturers producing high-performance interdigitated back contact (IBC) N-type panels on the markets, LG and SunPower. LG’s cells now use 30 busbars implemented on the rear side of the cell, resulting in a slick design with no visible busbars in the front and thus no cell shading. This new cutting-edge design uses high-purity N-type doped silicon and an additional special metalizing process on the back of the cell, contributing to a very low degradation rate, low current resistance, favourable high-temperature performance, and allowing LG’s module to achieve phenomenal efficiency of 22%.

It bears repeating that LG solar panels in general have high efficiency rates, as a result of their specific choice of cell technology and all-round approach to manufacturing. Here’s a quick breakdown of the numbers.

  • Mono X Plus efficiency – up to 19.8% at 370W
  • Neon 2 efficiency – up to 21.4% at max 370W
  • Neon R efficiency – up to 22.0% at max 380W

In addition, LG solar panels are now framed by extra-strong, double-wall aluminium frames which can bear loads twice the normal industry standards. The new frames are rated for 5,400 Pa of wind or snow pressure on the front side and 4,000 Pa on the rear side, while the industry standard is 2,400 Pa.

Finally, LG takes a double-or-nothing approach when it comes to detecting micro-cracks. LG flashes the panel both before and after lamination, inspecting the model twice to ensure that no defective cells are present in the finished solar module.

Performance Warranties and Service

As indicated by the overview, the LG solar warranty can be up to 25 years for the panel itself and, similarly to SunPower, the company also offers a quarter-century of performance warranty covering the panel’s power output and overall yield.

The LG performance warranty receives high marks for its scope and scale. Both the Neon 2 and Neon R models are estimated to keep producing as much as 90% of their nominal yield even after 25 years of use. This type of warranty speaks of LG’s confidence in the quality, long-term performance, and low degradation rates of their products. The 25-year warranty also includes repair or replacement of the solar module in case of manufacturing defects, free of charge


LG ships their solar panel packages all over the world secured with tough plastic-moulded corner sections in order to maximize safety during transportation. Seeing as one of the main causes of micro-cracks are transport mishandles, it’s very handy that their warranty covers transportation and installation. The warranty is provided by the Australian LG subsidiary, so you won’t have to deal with an overseas company.

Compared to other industry giants, LG solar panels may be said to surpass the standard warranty terms. Winaico, a quality solar module manufacturer by any metric, offers a 15-year product warranty for most of their product line and 25 years of performance warranty. SunPower may be LG’s peers in terms of offering a 25-year product warranty, but one should keep in mind their panels do have a slightly higher degradation rate. Similarly, REC offers a 20-year product warranty which can be extended by up to 5 years in certain conditions.

LG Pricing

At first sight, the LG solar panel cost may seem a bit steep, but note that the price includes a full turnkey solar system, installation by certified and reputable installers, and comes with the STC rebate and GST credit. The average LG solar panels price in Australia is given below.


System size

Average fully-installed cost
6 kW$8,885
8 kW$11,830
10 kW$14,300

Do keep in mind that the price may vary depending on your exact location, the inverter brand, and the specific installer.

If you are looking to replace a defective module or add another panel or two to your setup, those numbers will be of little use. In that case, you may want to look at one of the company’s most popular and affordable modules, the LG 300 solar panel, which can be bought for $317 a piece.

As we said, LG solar panels prices are known to be somewhat higher than other manufacturers. Let’s see what that means in practice. An average 6kW system by SunPower costs around $7,660, while their 10kW systems cost an average of $13,900, only slightly more affordable than LG. Another solar manufacturer which is highly spoken of, Winaico’ prices are lower still: an average 6kW system will run you about $7,000, whereas their 10kW systems go for an average of $11,000.


As far as discounts are concerned, keep in mind that LG sells their products via various local dealerships, so you will need to keep an eye out for special deals and offers at the local level. It never hurts to contact the dealers directly and leave your contact there, just in case.

Customer Reviews

Customers have recognized the LG quality and standing, grading the company’s solar modules at 4.8 out of 5 in 916 reviews, where the vast majority of LG reviews award them a 5-star rating. This is a common rating for the top tier of solar module manufacturers available in Australia, as both REC and SunPower have the same rating from around 550 reviews.

Generally, the reviews indicate that the Australian market is filled with quality solar module manufacturers. In a packed market, price is always the primary concern, but LG’s renowned and superior features can make the difference.

LG Solar Panels Alternatives

To see how the alternatives stack up, let’s take the NeON® H as a benchmark and compare it with products by other acclaimed manufacturers. 

Consisting of 120 monocrystalline N-type cells, the residential models in the NeON® H series have a maximum efficiency rate of 20.9% and power outputs of up to 385 W. They come with a 15-year product warranty and sell for an average price of about $430 per panel.

Many will immediately look for the heavyweight matchup of LG solar modules vs SunPower panels, so let’s see how these two compare first. The monocrystalline shingled cell technology of the SunPower P3 series (370-390 W) gives it a maximum efficiency rate of 19.9% and power output of up to 390 W. The panels come with their renowned 25-year Complete Confidence product warranty. The average price is a bit lower than LG, at $320 per panel.

Winaico is known for its policy of offering premium quality at significantly lower prices. Its WST-M6 series has efficiency rates between 19.54% and 20.14% and nominal power outputs between 325 W and 335 W. The series comes with a 15-year product warranty and sells for an amazing $240 per panel. This should suit your needs if you’re looking for affordable yet highly efficient options.

Hanwha Qcells, another South Korean manufacturer, is a company known mostly for its affordable products. Their Q.MAXX-G3 module outputs up to 375 W at an efficiency rate of 19.8% and has a product warranty of 15 years. The Qcells brand occupies a similar market segment as Winaico and its panels can be had for about $275. 

Finally, let’s pit LG vs Panasonic solar panels from their new N340 HIT series. The VBHN340SA17 HIT+, to give its full name, is a dual-layer, bifacial cell design with heterojunction technology, achieving the company’s highest power output per unit of surface to date. The 340W module has an amazing 20.3% efficiency rate and 25 years of warranty on both the product materials and the output. All this cutting-edge technology isn’t exactly cheap, though, and at $360 per panel, is right there in LG territory.
