LG NeON® H photovoltaic panels are based on innovative N-type cell technology, which, combined with the Half-Cut structure, significantly minimizes energy losses resulting from shading or high temperatures. This solution is a response to the needs of users seeking maximum efficiency from limited roof space, offering one of the highest energy conversion rates on the market. The unique design using multi-busbar m6 cells ensures better current flow and exceptional resistance to micro-cracks, which directly translates into the longevity of the installation. This series stands out from the competition with an exceptionally low degradation rate, guaranteeing stable power production for decades, which is key to a fast return on investment. It is a premium class product dedicated to demanding individual investors and enterprises for whom reliability and energy security are a priority. Thanks to the use of a reinforced frame and high-quality materials, these modules handle difficult weather conditions perfectly, maintaining an aesthetic appearance throughout their entire service life. Choosing the NeON H series is an investment in advanced engineering that redefines durability standards in modern photovoltaics.

What owners get
Up to 20.7% efficiency with N-type cells

N-type cells with M6 multi-busbar technology deliver 20–20.7% efficiency and lower LID/LeTID degradation susceptibility compared to conventional P-type PERC cells, translating into more stable energy yield in the early years of operation.

25-year product and power warranty

LG offers a full 25-year warranty on both the product and power output (guaranteeing approx. 89.6–90.6% of initial power after 25 years), which was among the longest warranty periods in the premium segment at the series' 2021 launch.

Reinforced build, microcrack resistance

The Half-Cut structure combined with M6 multi-busbar cells improves current flow and reduces the risk of microcracks and power loss under partial shading, which matters in atypical installation conditions such as partial shading from chimneys or antennas.

Tier-1 manufacturer reputation, 60+ years of history

LG Electronics has operated since 1958 and was historically regarded as a Tier-1 manufacturer with strict quality control, which translated into strong bankability for NeON H modules in project financing.

Trade-offs
Discontinued, limited service availability

LG officially ended solar panel production in June 2022 (decision announced February 2022), and the NeON H series is no longer sold. Availability of spare parts, warranty support, and future claims handling may be limited over time, despite LG's stated commitment to continued warranty support for existing installations.

Efficiency below current segment leaders

At 20–20.7%, efficiency is now clearly lower than newer comparable models (Sunlike Solar SKT420~455M10-108D6: 22.8%, LEDVANCE M435~455N54LB-SF-F7: 22.77%, Solitek SOLRIF D Black: 22.56%), meaning a larger installation area is required for the same 440–455 Wp power output.

Common questions

6 answered
Is the LG NeON H series still available for purchase?
No. LG exited the solar panel manufacturing business in June 2022, and the NeON H series has been discontinued. Some units may still be found in authorized distributor warehouses, but availability is very limited and prices tend to be higher than active market alternatives due to scarcity. LG continues to honor all issued warranties and maintains a replacement inventory for warranty service claims.
What warranty does LG offer on the NeON H series?
The LG NeON H carries a 25-year product warranty and a 25-year linear power warranty, guaranteeing at least 90.6% of initial rated output after 25 years of operation. Notably, the warranty also covers labor costs up to $450 per module for any required replacement, a benefit rarely offered in the industry that significantly reduces long-term financial risk for the system owner.
What is N-type cell technology in the LG NeON H, and why does it matter?
N-type cells in the NeON H series are phosphorus-doped rather than boron-doped, which eliminates Light Induced Degradation (LID). In practice, the panel does not lose output in the first weeks of operation, as commonly seen in P-type PERC modules. Combined with a 144 half-cut cell layout and LG's multi-busbar Cello Technology, shading losses are significantly reduced and the expected service life of the installation is extended.
How do LG NeON H 455W panels perform on hot summer days?
The NeON H series performs well at elevated temperatures thanks to a low temperature coefficient of power. This means the panel loses proportionally less output per degree Celsius of module temperature increase compared to typical P-type PERC cells. For rooftop installations where modules routinely reach over 60°C in summer, this translates into measurably higher annual energy yield compared to less efficient alternatives.
What is the rated power output and efficiency of the LG NeON H panel?
The top model in the series, LG455N2W-E6, delivers 455 Wp peak power at a module efficiency of 20.8%, among the highest ratings in the premium segment at the time of its release. The module consists of 144 half-cut cells in a 6x24 configuration and uses standard MC4 connectors, making it compatible with virtually all inverters and racking systems available on the market.
Are LG NeON H panels suitable for a pitched roof with partial shading from a chimney or dormer?
Yes. The half-cut cell design and multi-busbar m6 cells in the NeON H series handle partial shading better than conventional full-cell modules. When shade falls on only part of a panel, power loss is contained because each cell operates independently within two separate half-cell strings. For roofs with heavy or persistent shading, pairing the system with power optimizers or a string inverter featuring per-string MPPT is still recommended for best results.
