The LG brand has long been synonymous with producing high-quality electronics that deliver as promised. Their solar panel products are certainly no different. In fact, LG solar panels tend to trend alongside SunPower and Panasonic in terms of the best solar panels available to homeowners in the current market. Every LG solar panel is built to ensure confidence in your solar investment for the long haul. Below, we’ve broken down the many models of LG solar panels available today and reviewed the brand’s offerings based on power, efficiency, warranty, cost, and overall durability. Below, let’s detail exactly how LG stands up to other solar panel brands on the market today.

LG Solar Panels Models

NeON 2 Series (Black, BiFacial, 60 Cell, 72 Cell)

One of LG’s most popular solar panel offerings is the NeOn 2 range. This is arguably their best selling solar module that comes equipped with award-winning Cell Technology. It is one of the most powerful and versatile modules available today.

NeON R Series (R, Ace, Prime)

LG’s NeON R Series boasts powerful high-performing solar modules that work. Their unique proprietary cell structure seeks to eliminate electrodes on the front to decrease the potential for shading while increasing the possibility of true light absorption. The R Series is also known for its streamlined appearance on the roof itself.

Each of these panel offerings sounds good on paper, but how do they work in terms of efficiency and power?

Efficiency

Efficiency is where LG solar panels truly make their mark. Solar panel efficiency deals with how well a given solar panel can effectively capture sunlight and convert it into usable electricity. This is why you always want a higher efficiency rating on any panel you procure. In terms of efficiency, LG panels are well above the market average of 17%. The NeON 2 series boasts an energy rating between 18.7% and 19.6%. Each panel in the lineup also ensures a power tolerance rating of 0/+3% and resilience against wind, snow, rain and hail.

The highly powerful LG R-Series boasts an efficiency rating between 20.3% and 20.8%. Each panel in the top rated R-series also holds a power tolerance of 0/+3% and resiliency to rain, snow, wind and fire. Each LG range is ideal for any home solar setup, though you may want to go with SunPower if your roof is truly constrained for space. LG panels do take up a bit more of a footprint than SunPower panels do, but the overall efficiency of LG is largely on par with this solar giant.

Performance Output

In the world of solar, performance is rated by what is known as the temperature coefficient. This indicates just how well a solar panel will operate in less than perfect operating conditions. For each degree above 25 degrees C (77 degrees F), a panel’s electricity production will decrease by its temperature coefficient. While it may not seem important, temperature coefficient matters because your panels are more likely to see a full range of temperatures throughout the year than a consistent 77 degrees Fahrenheit reading. A good temperature coefficient is as close to zero as possible.

With LG solar panels, your temperature coefficient will vary based on the model you choose. The entire LG NeON 2 range of panels offers a temperature coefficient of -0.37%/C. This means that if a panels temperature goes up by one degree from 25C, the electricity production will be reduced by -0.37%, which is very respectable for solar panels. The LG R-Series boasts a temperature coefficient of -0.30%/C which is above the industry standard for energy output.

Additionally, LG does offer a 25 year output warranty term that guarantees at least 86% output efficiency by the end of your warranty. This is well above the industry standard.

Panel Technology

What makes LG solar panels so efficient and powerful? Well, it comes down to LG’s production methods. LG only manufactures monocrystalline N-type cells. These boast a lower degradation to budget poly or multicrystalline P-Type cells. They also offer greater overall efficiency. Most manufacturers in Solar, especially those on the cheaper end of the spectrum, produce combined mono and polycrystalline panels.

The NeON 2 modules also include multi-wire cell technology that employs 12 round wire busbars and an innovative finger design. The proprietary Cello cells don’t just look impressive, they improve performance and sunlight conversion efficiency capacity. It is also important to note that LG and SunPower are the only manufacturers that produce high-volume Interdigitated Black Contact N-Type Cells for the general market. The N-type design has extremely low degradation, high-temperature performance, lower electrical resistance, and an impressive efficiency at 375 Watts (R Series).

Durability

LG has made many impressive strides in solar panels, but their durability is hard to beat. Not Panasonic nor Tesla SunCity panels can boast the durable wall aluminum frames that have an impressive 5,400 Pa rating on the front and a 4000 Pa on rear side for wind that LG does. This is double the industry standard 2400 Pa for wind.

Impressively, a recent study by SECAust in Australia found that the NeON 2 modules were able to withstand an unprecedented 10,000 Pa load without any failure or interruptions in power. The NeON R series garnered similar results due to an even stronger aluminum frame profile.

Warranties

A good warranty means that a manufacturer stands by their products. LG offers a robust industry-leading 25 year warranty against any defects or issues that can occur within the solar panels themselves. Most solar panel manufacturers only offer an average 10-year materials warranty. After that, you’re on your own. This speaks volumes about LG’s overall confidence in the products they produce.

Cost

Cost is a big factor in choosing the right solar panels, which is why many people put off investigating LG. The brand name and leadership in the market lead many to believe that panels will simply be too expensive. However, we found that LG solar panels are typically priced between $2.64 and $3.30 per watt during installation, which makes them rather middle or the road in terms of cost.

The Takeaway

LG solar panels are an excellent choice for anyone who wants above-average efficiency, performance, and warranty on every product in the range. With cutting-edge technology and unheard of durability, LG definitely makes some of the best solar panels on the market today. This is a trustworthy and established company who wants to earn your loyalty. If you’re on the market for home solar panels or the best solar panels, give LG a look.
