LG NeON R panels are synonymous with the highest efficiency achieved thanks to an innovative N-type cell structure with electrodes placed exclusively on the back side. This design eliminates metal busbars from the front of the module, allowing for maximum surface utilization for light absorption and giving the installation a unique, modern appearance. This solution is dedicated primarily to single-family homeowners who have limited roof space but expect maximum power from every square meter. Back-contact technology makes this series perform much better in high-temperature conditions and low sunlight, which directly translates into stable energy yields throughout the year. What sets them apart from the competition is their exceptional resistance to degradation and a low temperature coefficient, which guarantees longevity and investment security. By choosing LG NeON R, you are investing in a premium-class product that solves the problem of aesthetics and low efficiency of standard solutions. It is the ideal choice for those looking for uncompromising build quality and technology that sets standards in the photovoltaic industry in terms of efficiency and reliability in difficult operating conditions.

What owners get
N-type back-contact (IBC) technology

Electrodes located exclusively on the rear side eliminate front-side busbars, increasing the active cell area and enabling up to 21.7% efficiency - clearly above peer comparables such as Boviet VEGA (20%) and ENCOR EC (20.59%).

Segment-leading efficiency

The 21.7% maximum module efficiency outperforms all comparable series in the peer set, including JS Solar JSHC166M120 (21.3%), making NeON R one of the most area-efficient series of its generation.

Low temperature coefficient

The power temperature coefficient is approximately -0.3%/°C, better than typical PERC modules (-0.35% to -0.40%/°C), resulting in more stable energy yield on hot, sunny days.

Full 25/25-year warranty still honored post-discontinuation

LG offers a 25-year product and power performance warranty, and despite ending production in 2022, the company continues to honor warranty terms for existing installations, including replacement modules from dedicated inventory.

Established Tier-1 manufacturer

LG Electronics has operated since 1958 and maintained Tier-1 status in solar PV for years, reflecting strong build quality and quality control for the NeON R series.

Trade-offs
Production discontinued, limited service availability

LG exited the global solar module business in February 2022, and NeON R production ended in June 2022. While warranty terms remain honored, availability of new units and replacement parts for expanding existing installations is now very limited.

Low unit power by current standards

The 360-375 Wp power range is significantly lower than newer generations of panels (up to 430-450 Wp in later NeON R variants), requiring more modules and mounting area for a given system size compared to currently produced premium series.

Common questions

6 answered
What is back-contact technology in LG NeON R panels and what does it mean in practice?
In LG NeON R panels, all cell electrodes are relocated exclusively to the rear side of the module. This leaves the entire front surface available for light absorption, yielding a module efficiency of 21.7% — well above standard PERC panels. As a side benefit, the installation looks sleek and uniform with no visible metal busbars on the front.
What product and power output warranty does the LG NeON R carry?
LG NeON R comes with a 25-year product warranty covering defects and workmanship, plus a 25-year linear power warranty. After 25 years of operation, the module is guaranteed to retain at least 90.8% of its rated output. This is one of the most comprehensive warranty packages available among residential premium solar panels.
Do LG NeON R 375W panels perform well on hot summer days?
Yes. The N-type back-contact cells in LG NeON R feature a low temperature coefficient of Pmax of approximately -0.30%/°C. Compared to typical PERC modules, power loss at elevated cell temperatures is noticeably smaller, translating to higher real-world energy yield during peak summer irradiance hours.
Is the LG NeON R series still available for purchase?
No. LG NeON R is a discontinued product line — LG Electronics has fully exited the solar panel business. Limited stock may still be sourced through distributors with existing inventory or on the secondary market, but supply is scarce. Always confirm current availability with your supplier before finalizing a system design to avoid future expansion issues.
Will LG NeON R 375W work well on a small roof where every square meter matters?
Yes, the NeON R series was specifically engineered for residential installations with limited roof space. A module efficiency of 21.7% means significantly more power from the same area compared to standard 17–19% modules. For a single-family home with a small pitched roof, this allows a higher total system capacity without increasing the module count.
How do LG NeON R panels differ from mainstream PERC modules?
The key difference is the N-type back-contact cell design versus standard P-type PERC cells. N-type cells exhibit lower light-induced degradation (LID), a better temperature coefficient, and higher tolerance to partial shading. The 21.7% efficiency of the 375W NeON R clearly outperforms typical PERC modules of similar wattage, which usually reach 19–20%.
