LG Electronics exited the residential solar panel business in June 2022. Existing LG NeON R, NeON 2, and Bifacial panels have no ongoing warranty support — LG no longer processes warranty claims, and their remaining inventory has been liquidated through distribution channels. NuWatt installs REC Alpha Pure-RX 470W as the closest spec replacement: same premium efficiency class, stable Reliance-backed parent, active manufacturer support.
LG NeON R is a discontinued product with no manufacturer warranty support. If you’re shopping for LG in 2026, you’re buying inventory — not a warranty. REC Alpha Pure-RX 470W is our recommended replacement: same premium segment, active manufacturer warranty, stable parent company.
LG Electronics exited the solar panel business in June 2022 as part of a strategic restructuring. The decision was not financial distress — LG Electronics itself remains a large, profitable company — but the solar business was shut down and no successor is honoring the NeON warranty contracts.
Any LG panels sold in 2026 are legacy inventory or gray-market imports. The manufacturer warranty that originally covered LG NeON panels is no longer serviceable because LG Solar Tech (the business unit that administered the warranty) no longer exists.
For new installs, we recommend REC Alpha Pure-RX 470W. Both REC and LG use premium cell technologies with similar low-degradation profiles. REC’s warranty is backed by Reliance Industries (NYSE: RIGD), which has actively invested in REC’s expansion since acquiring the company in 2021.
Existing LG NeON R owners: your panels continue to produce power normally. The concern is prospective warranty coverage, not current performance. Document your panel serial numbers, current production, and any fault codes today.
The Brand Stability Question
Brand Stability
Exited solar business June 2022, no warranty support
Our assessment
LG Electronics exited the solar panel business in June 2022. The LG NeON R and NeON 2 product lines are discontinued with no ongoing warranty support from LG. Homeowners with LG panels installed before 2022 are advised to document current production output now, as future claims cannot be processed.
Rating current as of 2026-04-09
Federal ITC & Domestic Content Adder
For commercial installs, the panel’s country of manufacture and ownership structure directly determine ITC eligibility and whether you qualify for the 10% domestic content adder. Here’s the honest assessment for LG Solar NeON R 380W.
Federal ITC & Domestic Content
Discontinued — FEOC status moot
Details
Manufactured in South Korea (Korean company, not a Foreign Entity of Concern). Discontinued in June 2022. No new production — FEOC status is informational only.
Informational only, not tax advice. Federal ITC qualification and domestic content adder eligibility depend on project-level analysis by a qualified tax professional.

Methodology
peak loss % = (panel temp − 25°C) × |temp coefficient|
STC (Standard Test Conditions) rates panels at 25°C (77°F). Every degree above that costs output at the panel’s temperature coefficient. Baseline -0.34%/°C represents an average PERC panel; HJT panels at -0.24%/°C lose roughly 30% less energy to heat. Annual kWh lost assumes an 8,000 kWh baseline system with 35% of the year spent at elevated summer panel temperatures. Based on NREL System Advisor Model (SAM) methodology for module temperature derating.

Output % by year — this panel vs baseline
Calculations use 4% annual utility rate growth compounded year over year. Degradation is applied compounding: each year’s production equals the prior year multiplied by (1 − degradation). Install cost is estimated as price/watt × 2.8× to cover inverter, racking, labor, and permits. The baseline panel assumes 0.55%/year degradation and a 80% year-25 performance warranty — the industry median for value-tier modules. Sources: NREL PV degradation rates study and panel manufacturer datasheets.

Frequently Asked
LG Electronics announced in February 2022 that it would exit the solar panel business by June 2022. The official reason was that LG’s residential solar unit faced "uncertainties in the global solar panel business" and the company decided to reallocate resources to other divisions. Unlike the SunPower bankruptcy, LG’s exit was a strategic decision by a financially healthy parent company — LG Electronics as a whole remained profitable. The effect for panel owners is the same though: no ongoing warranty support.
The warranty contract still exists, but enforcement is difficult in practice because LG Solar Tech — the business unit that administered warranty claims — no longer exists. LG Electronics has not publicly committed to honoring NeON warranties through another division. Some homeowners have successfully filed claims through their original installer, who may have commercial relationships that allow for panel replacement through distributor stock. If your NeON panels fail, contact your original installer first.
LG NeON R used back-contact (IBC) cell technology, similar to SunPower’s X-series. This gave it a clean all-black aesthetic (no visible front-side busbars), strong low-light performance, and one of the lowest temperature coefficients in its era (-0.30%/°C). For homeowners who chose NeON R for the aesthetic, the closest modern equivalent is the REC Alpha Pure-RX, which uses HJT cells with a similar clean appearance and actually improves on the temperature coefficient (-0.24%/°C).
REC Alpha Pure-RX 470W is the closest aesthetic match — both panels use a clean all-black design without visible front-side busbars, thanks to the HJT cell layout. For an even more specifically all-black look, Q CELLS Q.PEAK DUO BLK ML-G10+ is our bread-and-butter black-frame panel (NuWatt installs about 70% of our residential work with this panel). Both are on our /solar-panels page with full specs.
Yes. Besides LG (exited 2022) and SunPower (Chapter 11 2024), Panasonic discontinued its original HIT product line in 2023 (the "Panasonic EverVolt" brand sold today is a license arrangement with third-party cells, not the original Panasonic HIT). Meyer Burger (Swiss HJT manufacturer) is in active restructuring in 2024-25 with announced factory closures in Germany.
