LG NeON R Review – Premium High-Efficiency N-Type IBC Solar Panel
Before LG exited the solar panel manufacturing business in 2022, its NeON R series stood as one of the most advanced and premium residential solar panel options available. The LG NeON R earned widespread respect among homeowners, installers, and industry experts for its high efficiency, excellent durability, sleek aesthetics, and strong long-term warranties.
Even though LG no longer manufactures new solar panels, the NeON R is still widely installed today and continues to be serviced under LG’s warranty program. Many homeowners still consider it one of the best residential solar panels produced, and for good reason.
In this review, we’ll dive into the LG NeON R—covering its technical specifications, pros and cons, customer feedback, complaints, competitive positioning, and an expert verdict.
Introduction to the LG NeON R
The LG NeON R was LG’s flagship premium residential panel, designed to compete with the best from Panasonic, REC, and Canadian Solar’s HiHero+. It used N-type IBC (Interdigitated Back Contact) cell technology, which differs from traditional front-contact solar panels by moving the electrical contacts to the back. This allows for more sunlight absorption on the front of the panel and better overall efficiency.
With efficiency ratings above 22% and wattages up to 440W in residential-sized modules, the NeON R was designed for homeowners seeking maximum output per square foot. Its sleek, all-black design also made it a favorite for premium rooftop installations.

Positive Customer Feedback
Homeowners and installers often highlight the following positives about the LG NeON R:
-
Exceptional Efficiency
Customers consistently praise the panel for generating more power per square foot than standard modules. -
Aesthetics
Many buyers mention the sleek, busbar-free black design as one of the most attractive on the market. -
Reliable Warranty
Despite LG’s exit, homeowners appreciate that LG committed to honoring warranties for 25 years. -
Durability
Installers note that the NeON R panels held up extremely well in harsh weather conditions. -
Premium Feel
Buyers often describe the NeON R as a “luxury” solar panel with both performance and visual appeal.
Negative Customer Feedback
Despite strong praise, some recurring concerns show up in customer feedback:
-
High Upfront Cost
Homeowners note that the NeON R came at a significant premium over other high-efficiency panels. -
Discontinued Panels
Some buyers expressed concern about availability for replacements or expansions now that LG has left the solar market. -
Not the Highest Wattage
While efficient, the NeON R’s wattage (380–440W) is lower than today’s large-format panels. -
Warranty Concerns Post-Exit
Although LG has pledged support, some customers worry about long-term warranty fulfillment.
Common Complaints
Some specific complaints included:
- Supply Shortages – installers had difficulty sourcing NeON R panels after LG’s exit.
- Pricing Premium – some buyers questioned whether the performance justified the extra cost.
- Limited Scale – not suitable for large commercial or utility projects due to wattage limits.
Competitive Positioning
The LG NeON R competed directly with other premium residential panels such as:
- REC Alpha Pure (HJT, ~22.8% efficiency)
- Panasonic EverVolt H-Series (HJT, ~22.6% efficiency)
- Canadian Solar HiHero+ (HJT, ~23% efficiency)
Compared to these:
- The NeON R’s IBC technology gave it a unique advantage in aesthetics and efficiency.
- Its efficiency was on par with REC and Panasonic, though slightly lower than Canadian Solar’s HiHero+.
- It carried one of the highest premiums per watt, making it less cost-effective for some buyers.
- Now that production has stopped, REC and Panasonic dominate the premium residential space once occupied by LG.
Final Verdict & Recommendation
The LG NeON R was one of the most premium residential solar panels ever produced, offering exceptional efficiency, sleek aesthetics, and strong warranties. While LG’s exit from solar manufacturing means the NeON R is no longer in production, existing panels remain a top choice for homeowners who can still source them.
This panel is best suited for:
- Residential rooftops where space is limited.
- Homeowners seeking premium design with maximum curb appeal.
- Buyers who prioritize brand trust and warranty coverage.
If you can still find stock, the LG NeON R remains an excellent investment. Its efficiency, aesthetics, and reliability make it one of the most respected solar panels ever produced for the residential market.
