LG solar panels: are they worth it?
LG is well known for its high-quality electronics, and the company’s solar PV products are no different. In fact, LG solar panels appear alongside SunPower and Panasonic in EnergySage’s ranking of the best solar panels currently available to homeowners in the United States. Currently, LG’s residential product line focuses on the NeON series of panels: the NeON 2 and NeON R variations. The LG NeON R ACe series is especially worth a look, as a high-powered Smart module with an integrated microinverter.
Whether you’re debating the merits of SunPower vs. LG solar panels or simply trying to evaluate your solar PV options, a thorough review of solar panel product specifications is the best way to be confident in your solar investment. EnergySage’s LG solar panels review breaks down all of the details to evaluate how LG compares to other solar panel brands on the market.
LG solar panels compared to other panel manufacturers
Efficiency
The term “solar panel efficiency” refers to how well a solar panel will capture sunshine and convert it into useful electricity. A high-efficiency solar panel can produce more electricity than a lower-efficiency panel of the same size in the same conditions. For this reason, a higher efficiency rating is generally preferable.
The efficiency of your LG solar panels will vary depending on the specific model that you choose for your home. On the lower end, LG panels have approximately 18.4% efficiency, while premium LG solar PV products can operate with as much as 22.1% efficiency. This range is ideal for many home solar systems – very high-efficiency solar panels like SunPower typically come with a premium price tag and aren’t necessary unless your system size is constrained by the amount of space on your roof.
Performance of LG solar panels (temperature coefficient)
For this portion of EnergySage’s LG panel reviews, we used the temperature coefficient to evaluate solar panel performance. The temperature coefficient indicates how well your solar panel will perform in less-than-ideal conditions. Solar panels, like other electronics, operate at their best when they are kept cool (ideally around 25° C/77° F). The temperature coefficient gives you a sense of how your panel’s performance will change during hot sunny summer days.
For every degree above 25° C (77° F), your solar panel’s electricity production will decrease by its temperature coefficient. For example, LG’s LG370A1C-V5 panel, from its NeON R ACe product line, has a temperature coefficient of.0.3%/° C. This means that, if the panel’s temperature increases by one degree from 25° C (77° F) to 26° C (79° F), its electricity production will be reduced by.0.3%. If its temperature increases all the way to 35° C (95° F), electricity production will decrease by 3.0%.
Temperature coefficient is an important metric to consider because your solar panels will likely see more than a few hot and sunny days over the course of each year. Ideally, the temperature coefficient should be as close to zero as possible – a panel that has a temperature coefficient of.0.4%/° C is preferable to one rated at.0.5%/° C. LG’s solar panels offer above-average temperature coefficient ratings, ranging from.0.40 to.0.29%/° C.
Warranties
Whether you’re buying a TV, a car, or solar panels, the manufacturer should stand behind their product with a strong warranty. A solar panel’s materials warranty (sometimes referred to as the product or equipment warranty) is a guarantee that the manufacturer will replace your panel in the event of an equipment failure due to manufacturing defects or environmental issues.
LG offers an industry-leading 25-year warranty against any defects in their solar panels.

How much do LG solar panels cost?
You can’t make a decision about the right solar equipment for your home without taking cost into account. The total price you pay for a solar energy system with LG panels will vary depending on the other equipment (such as inverters and mounts) used in the installation. We reviewed quotes from installers on the EnergySage Solar Marketplace that featured LG solar panels to identify the range of you can expect to pay for your system. Overall, we found that LG systems are typically priced at between 2.46 and 3.38 per watt.
This means that, for a 6 kW system, your gross cost would be anywhere from 14,760 to 20,280. Most homeowners, however, will end up paying much less than the total gross cost. There are plenty of solar incentives and rebates to help you reduce upfront costs, including the 26 percent federal tax credit for solar.
How to find the best price on LG solar panels

About LG, Solar Panels
LG Solar produces high quality, tier 1 solar panels and are part of the giant South Korean company LG. While current production capacity isn’t clear, in 2017 the company produced around 2 gigawatts of panels. While this is only 23% of what the world leader Jinko produced in the same year, LG Solar is still a large player. and is focused on the premium panel market.
All the panels LG Solar currently sell in Australia have a 25 year full replacement product warranty, which is one of the best available in the world. Unlike most manufacturers, their product warranty includes the cost of labour required to install replacement panels.
LG Solar now sells four models of panels in Australia, the NeON 2, the NeON H, the higher efficiency NeON R, and the more entry-level Mono X Plus. The NeON 2, H and R have product and performance warranties of 25 years, while the Mono X Plus has a 15 year product warranty with a 25 year performance warranty.
LG has offices in every mainland state capital. While Tasmania misses out, this is much better coverage than most tier one manufacturers who usually only have a single office in Australia, or in some cases, none at all.
LG Solar Panels Are Reliable
LG claim that by the time they had installed 360,000 in Australia, only 9 had been returned. mostly due to poor installation.
LG Is A Huge Company
LG Solar is part of LG Electronics which is part of the South Korean corporation LG which used to go by the surprisingly chipper name, Lucky Goldstar. LG is enormous and has a market capitalisation of over 14 billion.
The net wealth of the entire population of the nation of Tonga comes to less than 14 billion. This means the LG Corporation has more money than some countries. (Note I’m not saying the value of Tonga itself is less than 14 billion, as the whole can be worth more than the sum of its parts. For example, I’m sure we could get Lex Luthor to pay more than 14 billion for Tonga as a whole.)
LG is involved in a wide range range of areas covering chemicals, electronics, and communications. The company has so many fingers in so many pies I’m surprised they haven’t grafted extra arms to their CEO.
While LG headquarters is in the South Korean capital of Seoul, solar panel manufacture takes place in the industrial city of Gumi, which, through some dark sorcery, actually manages to have a worse climate than Seoul.
LG has been tooling around with solar cells in some form or another for over 20 years, but they only entered panel manufacturing in 2009.
Mono X Plus panels
The original Mono X series of LG panels was phased out of Australia a few years ago. but LG have re-launched the Mono X line with their Mono X Plus panel series, which carry a lower 15-year product warranty compared to the NeON series of panels.
NeON 2 Panels
LG NeON panels come in two different types, the LG NeON 2, and the LG NeON 2 Black. LG NeOn 2 panels can have an efficiency of up to 21.4% which can make them very useful for making good use of a limited amount of roof space. The LG NeON 2 Black has slightly lower efficiency, but some people like its dark colour, so I highly recommend it for people who think black is the new black.
All the panels are salt mist and ammonia corrosion resistant and so are suitable for installation anywhere in Australia.
NeON R Panels
LG Solar‘s NeON R panels are of even higher efficiency than their NeON 2 panel and are up to 22% efficient.
NeON H Panels
The NeON H rooftop range will be available in 370W – 385W capacities in Australia from June or July 2021. Offering an efficiency of 20.1% – 20.9%, the NeON H is comprised of 120 half-cut solar cells.
To see more specifications of these products and compare them against other brands, see the SolarQuotes solar panel comparison table.
LG Chem Produces Battery Storage
LG produces a home battery storage system that is made by LG Chem and not LG Solar. these two parts of the company probably have nothing to do with each other.
Warranty Claim Procedure For Orphaned LG Customers
If you have purchased LG panels from a company that has since gone out of business, you should contact LG on 1800 042 568. They have advised that they have a dedicated dealer network that can arrange replacement of panels under warranty. Labor costs involved with panel warranty replacement are covered.
A Reliable Solar Panel At A Premium Price
LG panels have an impressive 25 year full replacement warranty on the NeON 2, R and H. This is among the best in the industry. At the time of writing June 2021 they are no longer the lowest cost panels with this level of warranty coverage. But if you are looking for high quality, reliable panels, then LG solar is a very good choice. and as the reviews below indicate, many Australian customers agree.

LG vs Sunpower Solar Panels: Everything You Need to Know
LG and Sunpower are the USA’s market-leading solar panel manufacturers. They both make an extensive range of home solar panels using the latest technology to help homeowners generate home solar electricity and cut down on their mains electricity costs.
But which of these companies is the best? Does LG or Sunpower make the best solar panels? You’ll know the answer once you’ve read through this guide to the two companies and their products. And then you’ll have all the information you need to make your choice between LG versus Sunpower solar panels.
Who is LG?
LG Electronics is a multinational electronics company that originated in South Korea in 1958. The company began as Goldstar and specialized in the production of consumer electronics and home appliances. They specialize in products like TVs, radios, washing machines, refrigerators.
These days LG is one of the top world corporations, employing more than 84,000 people worldwide. The company continues to specialize in consumer electronics. Still, it has branched out into technologies such as solar panels, where their technological advances are driven by the might of their enormous research development capabilities.
Who is Sunpower?
In many ways, LG and Sunpower couldn’t be more different. Where LG is an enormous international electronics conglomerate. Sunpower is a homegrown company specializing in solar power.
Sunpower was founded in the 1970s by Dr. Richard Swanson, a professor of electrical engineering at Stanford University. As a leading solar energy scientist, he received grants from the Electric Power Research Institute and the US Department of energy to further his research. In 1997, SunPower’s groundbreaking technology was used to power NASA’s Pathfinder rover.
Sunpower continued at the leading edge of solar cell technology and in 2008 produced a silicon solar cell with a world record efficiency of 23.4%. With these improvements in efficiency, Sunpower became a major manufacturer of home solar technology, making their billionth solar cell in 2014.
These days Sunpower is a NASDAQ listed company producing powerful and highly efficient solar panels for the world market.
Which of these companies is most successful?
The reason for these potted biographies of LG and Sunpower is to establish their place in the market and assess whether you can expect them to be around in the future. Why?
Both these manufacturers sell solar panels with twenty-five-year warranties. But a warranty is only as reliable as the company that offers it. If either company goes out of business, then that effectively nullifies your warranty. You need to be sure you’re buying from a lasting business.
It seems that Sunpower is going from strength to strength, and they aren’t going to stop selling solar panels any time soon since it’s their primary business. Equally, a company the size of LG doesn’t disappear overnight. What they might do, though, is stop producing solar panels one day, just as they are planning to do with their mobile phone operation.
Given that home solar is a relatively new industry with enormous potential for expansion, I think that you can be very confident that both of these companies are here for the long term. If I had to pick one over the other in terms of long-term prospects, I would choose Sunpower simply because they specialize in solar technology.
How do you know if a solar panel is any good?
I’ll quickly take you through some of the measures we use to work out the efficiency and energy production of solar panels.
Wattage
all solar panels are tested under laboratory conditions and given a wattage that rates their energy production under ideal conditions. If you buy a 350-Watt panel, that doesn’t mean it will produce that much power all the time, but different power ratings are an excellent way to compare solar panels.
Efficiency
Much is made of solar panel efficiency, and it’s important. Efficiency is a measure of what percentage of the sun’s light a particular solar panel can convert into electricity. efficient panels can produce more electricity per unit area than less efficient ones.
But, importantly, less efficient solar panels can still produce a high wattage if they are large enough. If you have plenty of space for your home solar panel installation, then don’t fall into the trap of valuing expensive, highly efficient panels over larger, cheaper panels that produce the same amount of electricity.
Twenty-five-year output
when you check the warranty of your solar panels, you will see that it guarantees a performance level after twenty-five years. This performance is measured as a percentage of its as-new power output. This number is an excellent measure of solar panel quality since it is effectively the manufacturer’s best guess of their product’s durability.
The higher the warrantied twenty-five-year percentage, the better the product.
Temperature coefficient
the temperature coefficient of a solar panel tells you how much heat impairs its performance. Solar panels are designed to operate optimally at temperatures up to 25°C or 77°F. The temperature coefficient tells you by what percentage performance reduces for every degree centigrade above this temperature.
| Measurement | Example | What it means |
| Size | 1558mm x 1048mm x 46 mm | Panel height, length and depth |
| Watts Per Square Meter | 200 | The panel produces 200 W of energy per square meter |
| Wattage | 350W | The panel can produce 350 Watts of power |
| Efficiency | 21% | The panel can convert 21% of solar light energy into electricity |
| Twenty-five-year output | 91% | After twenty-five years, the panel is guaranteed to produce 91% of its starting power |
| Temperature coefficient | -0.4%/°C | The panel’s performance goes down by 0.4% for every degree Celsius above twenty-five |
What products do these companies sell?
LG offers a range of domestic solar panels, including the NeON series and the NeON R series, in a few variations. The NeON is a powerful panel producing 355-375 W from sixty solar cells at an impressive efficiency of 21.7%
The Neon 2 is a more affordable solar panel with a lower but still impressive efficiency of 19.8%, producing 350-365W in their sixty-panel models.
Sunpower’s X series is their flagship solar panel, with high efficiency and top-of-the-range specifications. We’ll compare this with LG’s premium Neon panel.
Like LG, Sunpower produces a more affordable panel, branded the E series. I’ll compare this product with LG’s Neon 2.
Both companies produce several other products, but these are their most representative products and so the best to compare.
Comparing top of the range LG and Sunpower solar panels
Both company’s top-of-the-range panels have very similar specifications.
Even though the Sunpower is marginally more efficient, the LG delivers the most watts per square meter, but the difference is negligible.
Sunpower has a marginally better temperature coefficient, and the X series offers better performance after twenty-five years, but again not by much.
So the two panels are extremely close in all regards, but in terms of overall performance, the Sunpower X-Series is the very marginal winner.
Comparing cheaper LG Sunpower solar panels
when it comes to their more affordable products, the differences between the LG Neon and the Sunpower E-series are a little more marked.
The temperature coefficients are around the same, and Sunpower has a slightly better twenty-five-year output. However, this doesn’t guarantee the panel will work better after twenty-five years, just that Sunpower thinks that it will.
But this time, the LG is ahead of Sunpower in the most critical categories. The LG Neon 2 is quite a bit more efficient than the Sunpower, allowing the panel to produce 5% more energy per square meter than its rival. This is a big difference and gives LG’s Neon 2 solar panel the edge over Sunpower.
| Sunpower E-Series | LG Neon 2 | Best | |
| Power output | 327W | 365W | N/A |
| Size | 1558mm x 1046mm x 46mm | 1,700mm x 1,016mm x 40mm | N/A |
| Watts per square meter | 200 | 211 | LG |
| Efficiency | 20.4% | 21.1% | LG |
| Warrantied 25-year output | 92% | 90.1% | Sunpower |
| Temperature coefficient | -0.35%/ °C | -0.34%/ °C | LG |
| Size | 1558mm x 1046mm x 46mm | 1,700mm x 1,016mm x 40mm | N/A |
What about the price?
You will notice that I haven’t got to price yet, and “how much?” is often the first question you ask when you’re buying something, isn’t it?
vary depending on where and when you buy your solar panels, but it’s reasonably safe to say that LG’s solar panels are cheaper than Sunpower’s. If you want the best performance for your buck, then LG’s solar panels are better than Sunpower.
So which panels should I choose?
If money is no object and you want the best performing top-of-the-range solar panel, then Sunpower’s X-series is just marginally better than LG’s Neon. Depending on the in your region, if the NeON is cheaper than the X-series, it may represent better value for money.
When it comes to the battle of the mid-range solar panels, the outcome is much clearer, LG’s neon 2 performs better than Sunpower’s E-Series, and it’s cheaper, so LG comes out on top.
