    LG Solar Panels vs Q CELLS: Which Panels Are Best For You?

    When you’re looking to install a solar energy system, an important step is comparing solar panel brands to find the one that is best for you. You want to be sure you’re investing in high-quality panels that can efficiently turn sunlight into free electricity for many years.

    In this blog, we’re putting two solar industry leaders toe-to-toe to see which is the better brand panel: Q CELLS or LG Solar. We’ll be looking at each brands:

    The Cost of Q Cells vs the Cost of LG Solar Panels

    Cost is an important factor when considering which solar panel brand is the best for your project. Do you go with the top-of-the-line product with the best performance and higher price, or do you go for the middle-of-the-road option that combines good performance with a good price?

    Out of these two brands, LG Solar is going to be the more expensive option. LG Solar manufactures some of the highest-efficiency and highest-quality solar panels on the market today. But that technology comes at a price that isn’t feasible for every customer.

    In comparison, Q CELLS offers a more affordable product. However, while their solar panels are still very dependable and efficient, they won’t perform quite as well as LG Solar’s panels (more on that later).

    So if keeping costs on the lower side is an important factor for your solar energy system, you may want to opt for Q CELLS. However, if you want to optimize panel performance and produce the most electricity possible, LG Solar may be worth the extra cost.

    How Do The Efficiencies of Q CELLS and LG Solar Panels Compare?

    Solar panel efficiency is the percentage of electricity that panels produce from the energy they received from the sun. A higher efficiency means the panel has the ability to produce more electricity during a certain period of time.

    Most solar panels today have efficiencies ranging from 15% to 20%. LG Solar offers one of the most efficient panels widely available on the market today at 21.7%. Their least efficient panel is 19.6%.

    Q CELLS offers panels ranging in efficiency from 18.6% to 20.6%. While these don’t quite reach the efficiency levels of LG Solar’s panels, they still pack quite a punch for their price point.

    There’s one important distinction to make with Q CELLS panels and their efficiencies. To get panels that are near or above that 20% efficiency threshold, you’ll need to go with their Q.PEAK DUO line, which are made of half-cut cell panels. Instead of being comprised of 60 or 72 cells as with standard solar panels, panels with half-cut cells feature 120 or 144 cells. These panels are more efficient and oftentimes more durable than standard panels, but they’re also typically more expensive.

    LG Solar panels will likely be more expensive than Q CELLS panels with half-cut cells. However, LG Solar’s panels may also produce more electricity for a longer period of time (we’ll get to that in our section on performance warranties).

    Product Warranties: Do Q CELLS or LG Solar Have Better Panel Guarantees?

    Product warranties protect your investment from any manufacturing or material defects. The best solar panel brands offer long-lasting, extensive guarantees because they’re willing to stand behind their product.

    clean, energy, reviews, panels

    When it comes to both Q CELLS and LG Solar, LG offers a significantly better product warranty. Q-Cell offers a 12-year limited product warranty on some modules and 25 years on others. LG ups the ante a bit with a 25-year limited product warranty on all of their products. During this time, both manufacturers will either repair or replace faulty panels, as long as the issue falls within the warranty’s terms.

    However, LG Solar not only includes the material cost of the troubled panel, but also the cost of the labor required to perform the replacement. This is extremely rare among solar panel manufacturers, as in most instances, the customer will be on the hook for labor costs.

    However, if you install solar with Paradise Energy, you’ll have access to our Triple Ten Guarantee. which covers any labor associated with the repair and replacement of warrantied products, no matter what the manufacturer’s product warranty includes.

    Another thing to consider when evaluating panel manufacturer warranties is how secure they are as a company. A warranty is only as good as the company backing it. If your panel manufacturer goes out of business, there will be no one to stand behind those guarantees.

    When it comes to both Q CELLS and LG Solar, we have a lot of faith that both companies will be around to honor their warranties. Q CELLS has been a major manufacturer of solar panels since 1999 and continues to provide solar panels for a large portion of solar projects around the world.

    LG Solar, which has been producing high-quality panels since 2004, is a highly respected industry leader. Not only is their solar division doing well, but they have the backing of LG Electronics, a global tech giant. So if something does happen to LG Solar (which we have no reason to believe it will), LG Electronics will be around to honor those warranties.

    Which Panels Last Longer? A Look Into Q CELLS’ LG Solar’s Performance Warranties

    In addition to the product warranty, solar panels will also come with a performance warranty. This warranty sets the bar for the degradation rate of your panels. Solar panel degradation is the slow decline in production that occurs to all solar panels over time. That means each year the amount of electricity your panel is able to produce is less and less.

    Performance warranties exist to ensure your panels don’t degrade too quickly and that they’re able to produce large amounts of cost- and emissions-free electricity for decades.

    Each performance warranty promises that their solar panels will degrade at a specific rate year over year for a specific period of time. If they exceed this rate, the panel will be replaced or repaired.

    All Q CELLS panels that we currently offer are guaranteed the ability to produce 98% of their nominal power after the first year, and then degrade 0.54% thereafter. Ten years after installation, the panels will be producing at least 93.1% of their nominal power, and after 25 years, they’ll be producing at least 85%.

    LG Solar also offers a 25-year performance guarantee, however, their degradation rate is much lower. They guarantee that their panels will produce 98% after the first year, then 0.33% degradation rate after that to still produce at least 90.08% of their nominal power after 25 years.

    So by opting for LG Solar over Q CELLS, you’ll have panels that produce more electricity for a longer period of time.

    It’s important to note that the performance guarantee only covers a solar panel’s ability to produce a certain amount of electricity, not the actual electricity production of the panel. The actual production will depend on several external factors, like weather and how the solar panel was installed.

    If you install solar with Paradise Energy, we’ll have you covered for actual system production with our Triple Ten Guarantee. If your system produces less electricity than we estimate it will in your solar system proposal, we’ll literally write you a check for the difference.

    Should You Install Q CELLS or LG Solar Panels?

    Q CELLS and LG Solar both offer dependable and efficient panels for your solar power system. While Q CELLS come at a more accessible price, LG Solar delivers high-efficiency panels that degrade more slowly.

    If price is a big factor for you, Q CELLS will likely be the better of the two options. They offer above-average efficiency and have great warranties for a fair price. If you want top-of-the-line panels, or the space you have for your solar system is small compared to the amount of electricity you’d like to produce, LG Solar will likely be the better option.

    Brand Cost Efficiency Product Warranty Performance Warranty
    Q Cells Cheaper option than LG Solar 18.6% to 20.6% Efficiency 12-25-year product warranty All panels have a 25-year performance guarantee at 85%
    LG Solar expensive option than Q Cells 19.6% to 21.7% efficiency 25-year product warranty All panels have a 25-year performance guarantee at 90.08%. Also includes labor costs

    That said, if you narrowed your options down to these two brands, you won’t go wrong either way. Both solar panel brands will contribute to a long-lasting solar system that will produce tons of cost- and emissions-free electricity for many years to come.

    Update. LG Solar to close!

    Unfortunately, LG Solar has decided to exit the solar market and will cease manufacturing solar panels from mid-2022. This came as a huge shock to the solar industry as LG was regarded as one of the world’s leading manufacturers with a premium range of high-quality panels made using high performance, long-lasting, N-type silicon cells. See the official LG company statement.

    Over the last two years, many competing manufacturers had started to close the gap in performance by increasing panel efficiency using new cell technology while at the same time reducing costs. It appears LG wasn’t able to offer more competitive pricing and the company claims it was no longer viable to manufacture higher-cost premium panels with the increasing raw material costs.

    LG Solar Panels Overview

    With a long history in solar panel manufacturing, LG is considered an industry leader and has proven to produce some of the best performing and highest quality solar panels in the world. As opposed to most other manufacturers, LG uses higher-cost, premium N-type silicon cells on the popular Neon R, Neon 2 and the new Neon H panels which boost efficiency and increase lifespan by significantly reducing LID or light-induced degradation.

    LG Solar Panels Quick Summary

    Company History

    LG has a long history in solar photovoltaics beginning over 30 years ago when they first began research into silicon crystalline cells. The next 20 years of research and development laid a solid foundation before LG started large scale PV module manufacturing in 2009 at their facility in Gumi, South Korea. LG solar is a subsidiary of massive LG Corporation, the South Korean multinational company with over 220,000 employees globally and total revenue in the tens of billions.

    After over a decade of PV module manufacturing, LG is now onto the 6th generation panels and produce over 2GW of panels per year. As a Tier 1 manufacturer holding numerous awards, ultra-efficient cell technology and offering an industry-leading warranty, there are only a few solar companies who can compete at this level of quality, service and reliability.

    In Australia and North America, although more expensive than the competition, LG panels are very popular and highly rated by customers and solar installers alike as they not only look impressive with the high gloss black anodised aluminium frames, but the construction quality, detail and finish are of the highest standard.

    LG Panel and PV Cell Technology

    While most manufacturers produce a range of monocrystalline panels based on the more common, lower cost, P-type silicon cells, LG primarily manufactures panels using monocrystalline N-type cells which have higher efficiency and much lower degradation over the life of the panel. However, to be more competitive, LG Energy recently introduced a cost-effective range of panels called ‘Mono X Plus’ built on the lower cost P-type monocrystalline cells.

    The popular Neon 2 modules established LG as a leader in multi-wire cell technology with 12 round wire busbars and the unique finger design being incorporated into all Neon 2 and Neon 2 bifacial modules. The N-type ‘Cello’ cells look impressive and improve performance and conversion efficiency. Read more about Cello technology in the PV cell technology review article.

    LG solar panel efficiency

    • Mono X Plus efficiency. up to 19.8% at 370W
    • Neon H efficiency. up to 20.9% at 385W
    • Neon 2 efficiency. up to 21.4% at 370W
    • Neon R efficiency. up to 22.0% at 380W

    Neon R. IBC cells

    LG, along with SunPower, are the two major manufacturers producing high-performance IBC or Interdigitated Back Contact N-type cells. The LG Neon R IBC cells use 30 busbars integrated into the rear side of the cell. This means there are no visible busbars on the front of the cell and in turn no cell shading. This unique design uses high purity N-type doped silicon and has extremely low light induced degradation, lower electrical resistance, improved high-temperature performance and enables the Neon R modules to achieve an impressive 22.0% efficiency at 380W.

    Neon H. 380W to 385W

    New for 2021. The latest release from LG is the Neon H range. These next-generation panels are essentially a more advanced version of the Mono X plus panel which also use the half-cut split cell design, but the Neon H is built on high-performance N-type cells as opposed to the lower cost P-type cells used by most other manufacturers. The Neon H, where the H stands for Half-size cells, is very similar is design to most modern solar panels available today but is backed by a 25-year product warranty and guaranteed to still achieve at least 90.6% of the rated output after 25-years of use thanks to the high-purity N-type cells which almost eliminate the effects of light induced degradation or LID. Plus, LG’s strict quality control measures and the use of high-quality encapsulants and other components mean the panels could last well past 30 years.

    Mono X Plus. 365W to 370W

    To increase efficiency and performance, most of the solar industry shifted away from the traditional 60 cell panel layout to the now common half-cut 120 cell format. In a bid to be more competitive against the huge Chinese manufacturers, LG introduced the Mono X Plus range in mid-2020 available in 365W to 370W power ratings. These new panels use the more cost-effective P-type silicon cells and are made in China to the stringent LG quality standards. They specify roughly the same performance and efficiency levels of the 370W half-cut cell panels offered by the leading Chinese manufacturers Trina Solar, Jinko and Longi solar, but offer an improved performance warranty of 87.9% retained power after 25 years. How LG is able to achieve a higher performance warranty is likely to do with the cell manufacture and strict quality control measures, including LID and LeTiD minimisation.

    Neon 2. 355W to 370W

    The latest Neon 2 range of panels from LG, introduced in mid-2020, boosted the power rating from 355W to 370W by using larger size silicon wafers to cover more of the panel surface area and in turn, reduce the amount of exposed white back-sheet material resulting in higher efficiency.

    All Neon 2 panels utilise high-grade N-type monocrystalline silicon cells built using the sophisticated multi-wire ‘Cello’ technology in a standard 60 cell format. With an impressive 25-year product warranty on top of the 25-year performance warranty, the Neon 2 range are some of the most efficient and best performaning panels available. Read more about Cello cells in our PV cell technology article.

    See full details and specification sheet. LG Neon 2 370W panels

    Neon R. 370W to 380W

    The Neon R is the flagship of the LG range. With a maximum efficiency of 22.0%, the Neon R panels can generate up to 380W from a panel only slightly larger than a standard 60 cell panel. As explained above, this performance is due to the high-grade IBC N-type cells used. Naturally, the Neon R panels also come at a premium price, being around 45% more expensive than more common mono P-type panels. However, with the higher price comes ultra-high build quality, long life, improved low light performance, very high efficiency and extremely low degradation over the life of the panel. Thanks to constant cell refinements and manufacturing improvements, the Neon R power has increased to 380W.

    See full details and specification sheet here. Neon R 380W

    LG Commercial and Bifacial Modules

    LG also manufactures a range of large format (72 cell) solar modules for large-scale commercial applications using the same advanced cello multi-wire technology, as well as dual-sided bifacial modules which can increase power output by up to an additional 27%. See more about bifacial technology here.

    Panel strength and durability

    LG has engineered extremely strong double-wall aluminium frames on all modules which are rated well above average with an impressive 5,400 Pa rating on the front side and 4000 Pa on the rear side for wind loading, this is close to double the industry standard 2400 Pa wind rating.

    The Neon 2 modules underwent static load testing by SECAust Engineering consultants in Darwin Australia and were able to withstand an incredible 10,000 Pa load without failure, see report here. The extremely high strength and stiffness of the Neon 2 would allow the LG modules to be mounted in any high wind load regions around the world.

    clean, energy, reviews, panels

    The LG modules are rated to the highest level of corrosion resistance and can be installed in coastal locations with high levels of salt mist (maximum severity of 6), in addition to ammonia resistance.

    Quality and Performance

    To ensure no cells with defects or micro-cracks get through LG use two EL flash tests during production both before and after lamination. The high grade N-type cells used by LG have exceptional long term performance in regards to low light induced degradation (LID). LID is a common problem as all solar cells reduce output over time with the average power loss being 3% in the first year and approximately 0.8% per year after resulting in an average of 80-82% original rated capacity after 25 years. However LG cells warrants a much lower rate of degradation which improves overall performance and increased energy generation with a claimed 86-88% rated capacity remaining after 25 years.

    To ensure reliability and long term performance LG perform strict quality control and testing throughout the manufacturing process with the LG test laboratory certified by the 4 major testing laboratories VDE, UL, TUV Rheinland and Intertek. The latest results from independent testing organisation DNV GL rated the LG panels as as a ‘top performer’ in the annual ‘PV Module Reliability Scorecard Report’.

    Warranty and service

    LG is one of only six manufacturers offering both a 25-year product and performance warranty. on the Neon 2, Neon R and the new Neon H panels. SunPower and Panasonic are a few of the other manufacturers to offer a 25-year product performance warranty while the majority of manufacturers provide a 12-15 year product warranty period and 25-year performance warranty.

    The LG performance warranty is well above the industry average with a minimum 90.08% retained capacity after 25 years on the Neon 2 range, and an impressive 90.8% on the Neon R range. To offer this kind of warranty shows the high level of confidence LG holds in its products and highlights the long-life performance and low degradation of high-grade N-type silicon cells.

    LG Product Warranty

    • Mono X Plus. 15 years
    • LG Neon H. 25 years
    • LG Neon 2. 25 years
    • LG Neon R. 25 years

    LG Performance Warranty

    • Mono X Plus. 25 years to 87.9%
    • LG Neon H. 25 years to 90.6%
    • LG Neon 2. 25 years to 90.08%
    • LG Neon R. 25 years to 90.8%

    The care taken is also highlighted in the way LG distribute and ship panels around the world with all modules stacked and secured with tough plastic moulded corner sections for secure transportation. This is important as many in the industry know that loading or stress placed on modules during transportation can result in micro-cracking and cell failure which usually does not become evident until a few years after installation. With strong company support, extremely low warranty claims and a very good reputation for service, LG solar modules are certainly one of the best choices available.


    To reduce the environmental impact of manufacturing, in 2015 LG installed over 11,000 panels on a massive 3.2MW rooftop solar array on its solar panel manufacturing facility in South Korea. In total, LG has now installed over 18MW of solar across its factories in Korea.

    LG Electronics has been nominated multiple times by Corporate Knights as one of the top 100 most sustainable corporations and have stated they are committed to continuously improving sustainability, reducing emissions and moving closer to a circular economy. However, LG only rate as ‘above average’ on the Solar Scorecard so some more work can be done. See the full LG sustainability report here.

    It could be argued that simply by only manufacturing high grade longer-lasting solar panels, LG is in effect more sustainable than many other manufacturers who have had panels fail only a few years after installation. As faulty panels require replacement this essentially uses double the resources.


    Like most things, premium equipment comes at a premium price. LG panels do cost more than the competition with the Neon 2 coming in at around 30% more than standard mono modules but you get a lot more for your money. Solar is a long term investment, so it is necessary to take into account performance and degradation rates over the life of the system.

    clean, energy, reviews, panels

    Based on LG’s solid history of reliability, we have little doubt that even after 10 years LG’s Neon 2 and Neon R panels, which are built on high-purity N-type silicon cells, would noticeably outperform most other lower-cost panels on the market. The lower rate of degradation and higher power output adds up to a significant amount of additional energy when totalled over the life of the panel. In regards to service and support, considering the enormous size and history of LG corporation, there is little doubt LG will also be around to back up any potential warranty claims in the future.

    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


    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.


    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.

    Best LG Solar Panels

    • 345W NeON 2 Black Solar Panel

    • 400W High Efficiency LG NeON2 BiFacial Solar Panel
    • Compared to other options, this model is able to absorb 30% more light.

    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

    If you’re shopping for solar for your home or business, reading EnergySage’s LG solar panels review is a great place to start. LG has a 5-star manufacturer rating on the EnergySage buyers guide.

    REC vs LG Solar Panels-Which is Better?

    The market for energy, particularly solar panels, was almost completely dominated by REC Solar Panels. On the other hand, LG isn’t far behind it either. Solar panels from Q Cells and REC are strong, have a long warranty period, produce a lot of power, work well, and have many other qualities. Now, the question lies between REC vs LG solar panels which is better? To discover the solution and relevant facts about the differences between REC and LG solar panels, read the blog.

    REC vs LG Solar Panels Overview

    As you begin learning about REC vs LG solar panels, let us learn about the backgrounds of both companies and their role in this market. REC is a pioneer in the solar business and a top developer of solar PV technology. The cutting-edge Alpha series panels, which use high-performance heterojunction cells, have elevated REC to the same level as the top producers in the world and are among the most effective solar panels currently on the market. The more affordable REC Twinpeak and N-peak solar panels offer excellent value in the fiercely competitive solar market and are covered by above-average 25-year performance warranties in addition to a 20-year product guarantee.

    With a lengthy history of producing solar panels, LG is regarded as a leader in the field and has established itself as a manufacturer of some of the highest-quality and best-performing solar panels in the world. On the well-known Neon R, Neon 2, and the new Neon H panels, LG uses more expensive, premium N-type silicon cells than the majority of other producers, which boosts efficiency and lengthens lifespan by considerably reducing LID or light-induced degradation.

    REC vs LG Solar Panels Efficiency

    The phrase solar panel efficiency describes how effectively a solar panel absorbs sunlight and transforms it into usable energy. A solar panel with higher efficiency will generate more energy than a panel with lower efficiency of the same size under the same circumstances. Because of this, a greater efficiency rating is typically preferred. Now, let’s learn REC vs LG solar panels efficiency.

    REC Solar Panel Efficiency

    Depending on the particular model you choose for your system, the efficiency of your REC solar panels will alter. An efficiency rating of 19.1% to 22.3% is assigned to solar panels in the REC product range. A summary of each REC model’s efficiency is provided below:

    REC Series Efficiency
    Alpha Pure R 20.7%-22.3%
    Alpha Pure 21.1%-22.2%
    N-Peak 2 (black) 19.1%-20.3%
    Twinpeak 4 (black) 19.4%-20.3%

    LG Solar Panel Efficiency

    Depending on the particular type you pick for your house, the efficiency of your LG solar panels will change. On the low end, LG panels have an efficiency of around 18.4%, while their top-tier solar PV products have an efficacy of up to 22.1%.

    LG Series Efficiency
    Mono X Plus Up to 19.8%
    Neon H Up to 20.9%
    Neon 2 Up to 21.4%

    In 2019, the company unveiled its Alpha Series solar panels. It was the highest-capacity 60-cell module on the market at the time, per REC. Panel effectiveness of up to 22.2% is provided by Alpha Pure, which followed the Alpha and is offered in the following wattages: 385W, 390W, 395W, 400W, 405W, and 410W. At first, the Alpha had maximum panel effectiveness of 21.7%.

    LG Solar Panels

    Whenever the topic comes regarding REC vs LG solar panels capacity, you must know that the two main producers of high-performance IBC or Interdigitated Back Contact N-type cells are LG and SunPower. Thirty busbars are built into the back portion of the LG Neon R IBC cells. As a result, the front of the cell has no obvious busbars and, consequently, no cell shading.

    The Neon R modules can achieve a remarkable 22.0% efficiency at 380W thanks to this innovative design, which makes use of high-purity N-type doped silicon and has extremely low light-induced degradation, reduced electrical resistance, and better high-temperature performance.

    Here is a list of Capacities of models of LG Solar Panels:

    LG Series Wattage
    Mono X plus 370 W
    Neon H 385 W
    Neon 2 370 W
    Neon R 380 W

    REC vs LG Solar Panels Output

    After a year of use, the output of both REC and LG solar panels will have decreased by nearly 2%. This decreased rate is in line with and even better than most panels. However, for the remaining life of both these panels, their outputs will decline differently. Per year, the REC panels’ output will go down by 0.25%. On the other hand, the output of LG panels will go down by 0.3% per year. This may seem like a minimal difference but at the end of 25 years, the output of LG panels will be 90.8% which is lesser than the 92% output of REC panels. In such a scenario, the REC panels will have an advantage over the LG ones. This should have given you a deep understanding of REC vs LG solar panels output. After this, let’s look at REC vs LG solar panels price range

    REC vs LG Solar Panels Price Range

    As you compare, REC vs LG solar panels price range, you must remember that the majority of REC solar PV systems are a good value in the home solar market because they are usually priced between 2.32 and 3.10 per watt.

    When comparing REC vs LG solar panels price range, it is found that the price for LG systems usually ranges from 2.46 to 3.38 per watt.

    REC vs LG Solar Panels Which Is Better?

    So, REC vs LG solar panels which is better? Well, both REC and LG Solar create solar panels that are visually pleasing. For customers who prefer it, REC has the benefit of offering its panels in an elegant all-black design. The LG 375, in contrast, has dark blue cells as opposed to REC’s black ones.

    The production of the REC panels will decrease by 0.25% annually, whereas the output of the LG panels will decrease by 0.3% annually. Even though this might seem like a very small change, the output of the REC panels will be 92% as opposed to 90.8% for LG after 25 years. This results in 1.2% more energy produced over the system’s lifetime, providing REC with a significant advantage.

    Here is a thorough description of the comparison of both models:

    Brand REC LG Solar
    Model REC 375AA LG375Q1C-V5
    Type Monocrystalline Monocrystalline
    Wattage 375 375
    Module Efficiency 21.4% 21.7%
    Annual Degradation Rate 0.25% 0.3%
    Rated Output 92.0% 90.8%
    Power Warranty Type Linear Linear
    Product Warranty 25 years 25 years
    Height (in) 67.8 66.9
    Weight (lb) 43 39

    In conclusion, it is obvious that high-end solar panels are a great choice for any homeowner, and both REC and LG Solar produce them. Despite having a 0.3% lower efficiency than the LG 375Q1C-V5 panels, the REC 375AA panels have a better degradation rate, leading to a higher overall production over a 25-year period. Both panels have excellent 25-year warranties, but the REC panels come with a 25-year work warranty in addition to the standard 25-year product and performance warranties. So, in most terms, REC is better than LG.
