LG NeON®H photovoltaic panels are based on innovative N-type cells, which translates into significantly higher efficiency compared to standard modules available on the market. A key differentiator of this series is the use of Half-Cut cell technology, which divides the panel into two independent sections. This solution effectively minimizes energy losses caused by partial shading, which is crucial on roofs with complex architecture. These models are characterized by exceptional resistance to LID and LeTID light-induced degradation, ensuring that the installation maintains its declared power for decades, eliminating the problem of rapid component aging. LG NeON®H solves the dilemma of limited mounting space, delivering more energy from every square meter than competing products. Another advantage is the very low temperature coefficient, guaranteeing stable operation and high yields even on hot, sunny days. The series is particularly dedicated to premium investors and single-family homeowners looking for uncompromising reliability and aesthetics. It is distinguished from other solutions by its reinforced frame design, providing resistance to extreme snow loads and strong winds. By choosing these modules, you gain the certainty of long-term savings and security resulting from advanced engineering and rigorous quality control of every cell.

What owners get
N-type cells with Half-Cut technology

N-type cells combined with half-cut cell technology deliver lower LID/LeTID degradation than standard PERC modules, resulting in more stable long-term energy yield and reduced losses from partial shading.

Efficiency up to 21.2%, matching segment leader

Peak efficiency of 21.2% matches Meyer Burger Glass (21.2%) and exceeds JA Solar JAM60S21 (21.0%), placing LG NeON®H among the top-tier comparable premium series.

25-year product and power warranty still honored

Despite ending manufacturing, LG continues to support the 25-year product and performance warranty, maintaining inventory for warranty replacements - reducing risk for existing investors.

Reinforced frame construction

The reinforced frame design provides higher resistance to snow and wind loads compared to standard aluminum frames, which is important for installations in regions with harsh climate conditions.

Low power temperature coefficient

A very low temperature coefficient limits power losses on hot days, ensuring more stable energy production compared to modules with typical temperature parameters in this segment.

Trade-offs
Production discontinued - series withdrawn

LG officially ended solar panel manufacturing in June 2022, exiting the solar business entirely. This means limited availability of new modules and potential difficulties with fast service and matching replacement parts going forward.

Efficiency below peer comparable leader

Maximum efficiency of 21.2% is lower than Phono Solar Twinplus M4-9B-R (21.3%), making it slightly less area-efficient than a direct competitor at the same 390 Wp maximum power.

No bifacial variant in this configuration

The analyzed NeON®H series is not bifacial (is_bifacial: false), while LG's parallel NeON H BiFacial variant allowed additional yield from reflected light - the absence of this option limits use on flat roofs, carports, and commercial installations.

Common questions

6 answered
Are LG NeON H panels still available for purchase?
The LG NeON H series is officially discontinued — LG exited the solar panel business in June 2022. New units may still be found sporadically through authorized distributors selling off remaining inventory. LG has confirmed, however, that it continues to honor both product and power output warranties for all previously sold modules throughout the full 25-year warranty period.
What warranty does the LG NeON H carry, and does LG still honor it after leaving the market?
The LG NeON H comes with a 25-year product warranty covering material and workmanship defects, as well as a 25-year power output warranty. LG officially confirmed that despite exiting the solar market in 2022, all warranty obligations to end customers remain in force. This is a key consideration for investors purchasing remaining stock from distributors.
How does the half-cut cell technology in the LG NeON H affect performance under shading?
Half-cut cells split the panel into two independent electrical sections. When shade falls on one part of the module — from a chimney or dormer, for example — the other half continues operating at full capacity. In practice, partial shading losses are up to several percentage points lower than with conventional full-cell modules, resulting in higher annual energy yield on roofs with complex architecture.
What is the efficiency of the LG NeON H 390W module, and is it actually impressive?
The 390 Wp LG NeON H achieves efficiency above 21%, which placed it among the top-performing residential modules available at launch. This means more energy per square meter of roof space compared to standard PERC modules. The N-type cell technology also minimizes LID and LeTID degradation, so the high rated power is maintained throughout the panel's operational life.
Does the LG NeON H perform well in summer when rooftop temperatures climb significantly?
Yes. The N-type cells used in the LG NeON H feature a very low temperature coefficient for Pmax (approximately -0.30%/°C), outperforming typical PERC modules (-0.35 to -0.40%/°C). On a hot day when panel temperature reaches 65°C, power losses are noticeably smaller than with competing products. This advantage is especially relevant during Polish summer conditions, when the system must maximize every hour of sunlight.
Can the LG NeON H frame handle heavy snow loads and strong winds?
Yes. The reinforced aluminum frame of the NeON H series is engineered to withstand a front load of 6,000 Pa (equivalent to a thick snow pack) and a rear load of 5,400 Pa (wind force). These ratings significantly exceed the standards required by Polish building codes, making the modules suitable for both lowland roofs and mountain regions with elevated risk of strong gusts.
