Australian office?

LG Solar has an office in most major cities in the world. In Australia, their main office, which also serves as the key warehouse, is in Eastern Creek, Western Sydney.

They’ve also set up satellite offices in all states, with the exception of Tasmania.

Why an Australian office is important

Having an Australian office helps in improving customer service to the LG solar panel homeowners. It makes it easier for customers to contact the company in case of any warranty issues, instead of having to call offices in South Korea for help.

An Australian office also ensures that customers won’t have to rely on their local solar installers, who have proven to be very unreliable.

Are LG solar panels perfect for rooftop solar?

Yes! The high module efficiency of LG panels means that you don’t need many panels on your roof. This makes them the perfect rooftop solar option 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.

Efficiency

The Neon R Series panels come with an initial efficiency of 97% and maintain at 95.03% after the 10th year. After 25 years, LG guarantees a 90.8% efficiency.

Warranty/ Guarantee

LG guarantees you an extended 25-year product and performance warranty, which also covers the labor and parts costs for the same period.

Peak Performance

Under optimal conditions, this panel has a maximum power output of 380W from a 60-cell module with a 22.0% efficiency.

Panels needed for 5kW solar PV system

Thanks to the high performance, your 5kW solar system will only require 13 solar panels to meet your daily energy needs. This makes it ideal for smaller roofs and those that experience shading on occasion.

Datasheet: NeON R Series

NeON R Prime

The NeON R Prime Series comes with the beloved all-black look, with a high power output and a relatively high module efficiency. This series was developed for homeowners that weren’t willing to compromise the aesthetics and still prefer the all-black LG solar panel look, but with the same efficiency and performance.

Cell technology

LG Neon R Prime still uses Back-Contact Technology like the R series. The absence of busbars on the panel fronts gives the panels a sleek look, increases its light absorption and improves its reliability.

The N-type cells used also ensure a near-zero Light Induced Degradation.

LG-NeON-r-Prime-Black-cell-tech

Efficiency

The LG NeON R Prime features a 98.0% efficiency during the first year and 95.30% after the 10th year. By the 25th year, the panel guarantees you 90.8% of its initial performance.

Warranty/ Guarantee

LG solar guarantees a 25-year product and performance warranty on the NeON R Prime panels, including up to $450 in labor and parts costs.

Peak Performance

LG’s NeON R Prime can generate up to 370W under the right conditions with a 60-cell module. The newer models have a high efficiency of 21.4%.

NeON R ACe

LG’s NeON R ACe is another high-power AC module in the NeON R series, designed to strike a balance between high output, flexibility, aesthetics, and fast installation.

ImageFeatures Score
- Monocrystalline/N-type
- Back Contact technology
- Integrated microinverters on solar panels
- Easy remote monitoring system
- 25-year product warranty with 90.8% power output guarantee
- High output and better aesthetics on the roof
- 5400 pascals front load and 4000 pascals rear load
LG-NeOn-R-ACe-solar-penl-review

Cell technology

LG NeON R ACe also uses the Back-Contact Technology that eliminates the front electrodes. This increases the panel’s light absorption and gives it a sleek modern look.

What makes this panel stand out is the presence of small integrated microinverters, which now replace the junction box.

Micro-inverter

The main difference with the ACe series is the use of micro-inverters connected to the back of each panel. The micro-inverters convert DC to AC directly below your panels, reducing the number of extra cables and installation parts required. This also eliminates the need for a central inverter.

This panel is perfect for roofs with partial shading issues.

LG-NeON-R-ACe-micro-inverter

Efficiency

The NeON R ACe series guarantees 95.3% of its initial power output after 10 years and 90.8% of the labeled output after the 25th year.

Warranty/ Guarantee

LG provides a 25-year performance and product warranty, inclusive of up to $450 in labor and parts costs in case the panels or inverters need repair or replacement.

Peak Performance

The NeON R ACe comes with an efficiency rating of 21.7% with a 380W 60-module cell. This panel allows individual monitoring of each solar panel through LG’s EnerVU software for optimal power output every day.

The software relies on the microinverter under each panel, allowing you to monitor each panel’s output through your phone or computer, identify potential cell shading and manage system troubleshooting.

Panels needed for 10kW solar system

For a home running a 10kW solar system, you’ll only need 26 NeON R ACe solar panels. Their high output and efficiency allow you to gain more power using less space than the conventional panels.

Latest leap forwards for LG solar panels

LG Solar panels’ efficiency has been improving over the years. Back in 2012, the company’s most efficient panel had a module efficiency of 17.8%. Today, a standard LG panel has a module efficiency of about 18.6%.

In 2013, the company created a new high-performing N-type NeON solar panel that was also cost-efficient and space-efficient. In 2017, LG designed the NeON R panel, the most efficient and powerful of the brand, which boasts a high module efficiency of 22.0%.

LG NeON H is the latest solar panel from LG. This panel has a high power output and features the innovative N-type half-cut solar cells of the company.

Why LG solar panels?

LG solar panels boast one of the best module efficiencies in the solar 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-year warranty is great for consumers, compared to the 10 offered by most Tier 1 solar panel manufacturers. This makes it a popular PV solar choice in the Australian market.

The parent company, LG corporation, has been in the solar industry for many years. 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 Technology (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.
