LG Solar, Solaria and SunPower offer high quality, top efficiency, and very reliable panels and they push to make the best panels. For this comparison and review, we will provide general information for companies and will be focused on their best solar modules.

LG Solar Panel

LG Solar has a long history in manufacturing solar photovoltaics starting over 30 years ago. In 1985 they started their research in solar power. The most popular LG panels are the NeOn 2 module series including LG330N1C-A5; LG315N1C-G4; LG350Q1C-A5. The LG Neon Series is a good investment with efficient between 18.6% to 19.5%. Furthermore, the technology used has helped them to gain more improvements in efficiency. 

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

Solaria logo

Solaria was founded in the early 2000s. Their solar panels are known for their quality, durability, and performance. Solaria’s solar modules have high power and reaching 20% efficiency by having an attractive design. Compared to other manufactures, these solar panels have fewer gaps between the cells, leading to high-efficiency panels.

The models that we offer from Solaria are PowerXT 370R-PD and PowerXT 400R-PM.

SunPower Logo

Monocrystalline X series solar panels rank as the most efficient solar panels with an efficiency that reaches nearly 22%. They sell their products only through trained dealers as they have to check and maintain quality to ensure that the panels are installed correctly. SunPower offers a great 25-year warranty. But they are expensive, much more expensive even than the top manufacturers like LG and Solaria.

Solar Model: LG 360 Q1K-V5

For many, the new panel from LG is the way to go because it has all. It comes with a 25-year warranty with a performance 90% at year 25, 360 watts of power; and is the best type-N cell technology on the market. The all-black 360 watts LG Prime has a great design. 

Solar Model: Solaria Power XT 370R – PD

Solaria has increased the module’s efficiency, improved its warranty to reach its top competitors, and its all-black design on the black finish is very aesthetic. What is innovative in the way they found to hide all the silver lines on the front of the module while increasing power output. When you compare the all-black module with LG, you will see that Solaria reaches 370 watts while LG is at 360W. Furthermore, Solaria modules have 4 different sections meaning that the panel will perform better than LG in shaded areas created by snow or by the tree branches. The price you get for it is below the LG Premier panels and it doesn’t compromise the quality.

Solar Model: X21-350-BLK

SunPower X-series was built with Maxeon Cell Technology. It has the lowest degradation rate on the market and also has probably the longest expected lifespan that exceeds the standard 25 years. However, SunPower has a big disadvantage when it comes to price. Their solar panes are way more expensive than Solaria and LG Solar. Secondly, their solar panels produce less energy as of 2020. Also in recent years, the company has undergone a lot of changes and that has been reflected in customer service and people have a lot of complaints against the company.
