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. ## About this series 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. ## Notable figures - Module efficiency of 20.0% is 1.9pp below average for \*\*N-type 400-450W\*\* panels (median: 21.9%) - At 200.1 W/m², this panel generates 18.2 W/m² less per unit area than \*\*N-type 400-450W\*\* median (218.3 W/m²) - -0.33%/°C temperature coefficient - 0.04pp worse than \*\*N-type 400-450W\*\* median (-0.29%/°C), expect higher hot weather losses - In the top 87% for efficiency among all N-type panels ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/datasheet-neon-h-n2w-440-455w-e6-lg-656a10c7c898.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +4.5 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +4.5 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, +4.3 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | Cooler, +4.3 pp, +5 yr warranty | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | Cooler, +4.3 pp, +5 yr warranty | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | Cooler, +4.3 pp, +5 yr warranty | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | Cooler, +4.3 pp, +5 yr warranty | | [LG LG445N2W-E6](https://comparepv.com/panel/lg-lg445n2w-e6) | 445 W | Very close match | | [LG LG450N2W-E6](https://comparepv.com/panel/lg-lg450n2w-e6) | 450 W | +10 W, +0.5 pp | | [LG LG455N2W-E6](https://comparepv.com/panel/lg-lg455n2w-e6) | 455 W | +15 W, +0.7 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +150 W, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +145 W, +3.6 pp, +5 yr warranty | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +140 W, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +140 W, +3.4 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/lg-lg440n2w-e6 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
