LG Solar Panel Review 2021

Updated: 17 December 2020

South Korean electronics giant LG has dominated the world of electronics for almost three decades now. The company has been known for producing high-quality and durable products for both household and commercial uses. It’s, therefore, no surprise that their PV solar panels are among the best in the industry.

LG solar panels boast of one of the best module efficiencies in the market at 20.8%, just a little shy of the leading SunPower panels. This means it can generate much more energy per-square-foot, compared to most brands out there.

Their 25 years warranty, compared to the 10 offered by most Tier 1 solar companies, is also great for consumers.

The parent company, LG corporation, has also been in the market for a long time with a diverse range of products. This works as great security, giving you confidence that they’ll be in business long enough to honor their warranty.

Cell technology

LG solar panels use their award winning Cello TechnologyTM (Cell connection with Electrically Low loss, Low stress, and Optical absorption enhancement) to create some of the best solar modules in the market.

The technology features 12 thin circular wires that increase the panel’s light absorption rate and reduce any power-generation losses.

It also embraces the N-type cells instead of the usual Boron-Oxygen pair to eliminate any Light Induced Degradation (LID).

Lastly, the technology has introduced a double-sided cell structure enabling the panels to generate electricity from both the front and back sides.

Are LG solar panels perfect for rooftop solar?

Yes! The high module efficiency of LG panels means that you don’t need so many panels on your roof. This makes it ideal for homes with small rooftops. The panels are very durable and can withstand heavy snow loads and wind loads of up to 6,000 pascals.

It’s, therefore, the perfect rooftop solar option for any home.
