Panasonic and LG Solar are companies that offer some of the best solar panels in the industry. They offer high quality, top efficiency, and very reliable panels, which is why they offer "premium solar panels". For this comparison and review, general information for both companies will be provided, focusing on their best solar modules.

Panasonic Logo

Panasonic is one of the world's largest manufacturers and a popular choice for homeowners. It's the best option if you are looking for a trustworthy company that has been in the market for a long time. You want to choose a company that is able to support you throughout the whole life of the solar panels. Panasonic guarantees that your HIT panel will provide a 90.76% power output after 25 years. That's 13% more power compared to what is offered by a traditional solar panel warranty. Panasonic panels are highly rated and reviewed in the United States.

The models that we offer from Panasonics are VBHN 330 SA17 and VBHN 340 SA17.

LG Solar Panel

LG Solar has a long history in manufacturing solar photovoltaics starting over 30 years ago. In 1985, they started researching solar power. The most popular LG panels are the NeOn 2 module series including LG330N1C-A5d, LG315N1C-G4, and LG350Q1C-A5. The LG Neon Series is a good investment with efficiency between 18.6% to 19.5%. However, they are not as efficient as Panasonic panels. The reason why LG is such a highly ranked solar option is due to the strength of the company.

The models that we offer from LG Solar are LG335, LG345, LG350, LG355, LG360, and LG375.

HEIGHT - INCH 62.60 66.38
WEIGHT - INCH 41.50 40.00

Both companies are strong, with a long history in the solar industry. The key disadvantage of the LG solar panels is they are not the most efficient panels compared to Panasonic. However,  LG solar panel's warranty is a better warranty than the industry's average.


Both solar panels come with a great warranty; a double 25-year warranty from Panasonic and LG. That means that both companies will stand behind their products long term and will repair and replace any damage that will occur to your system. This long warranty is available because both companies have a strong reputation in the solar industry and demonstrate their commitment to their customers.


Panasonic and LG Solar also design very aesthetically pleasing mono solar panels that come in all-black design or black cells with a silver frame. Both manufacturers offer superior design and they can be integrated with a wide variety of applications that meet your needs.


Both companies are attempting to offer high-quality solar panels with high-efficiency solar cells. If we compare both products, we see that Panasonic's model has a 20.3% module efficiency compared to LD Model which has a 20.4% module efficiency. Both panels have a low annual degradation, which will result in additional value to the solar panel. They will continue to produce energy even after 20 years on similar production levels.

So which one is better, Panasonic or LG Panels? Both Panasonic and LG Solar are great solar panels for any system. For premium modules, both have a great price point. Choosing the best inverter and racking system is also very important in getting the most of your solar investment too.

Panasonic has a rate of 90% year 25 performance guarantee. The HIT technology has a great performance for the New England climate. The advantages of HIT technology is that heterojunction technology minimizes electron loss. Panasonic panels have a higher performance at high temperatures. This is the best solar panel if you live in a place where the sun is available all year round. Also, it has dual-sided cells that multiply the energy output, and it has smart water drainage for peak power. Lastly, the company has strict quality testing standards for long-life performance.

Solar Model: LG 350N1C-V5

Neon series from LG has proven itself to have a track of great durability. The module has a black frame and a white back sheet. When it comes to power output the panel has 350 watts and comes with a 25-year warranty. It reaches an efficiency of 20.4% and power output warranty derating of 0.5%.
