LG Solar performance guide

LG discontinued solar panel production in 2022, but millions of LG NeON panels remain in service. These are high-quality monocrystalline panels with good degradation rates, though warranty service is now handled by third parties.

Warning signs to watch for

LG panels are reliable, but the 2022 factory closure means warranty claims now go through third-party administrators with slower processing times. If you notice any panel output dropping more than 15% below adjacent panels, act promptly โ€” claim documentation is more important now than ever, and delays in reporting can complicate the process.

LG Solar โ€” frequently asked questions

Are LG solar panels still covered by warranty?+

LG Solar exited the panel business in 2022. Warranty claims for LG NeON panels are now handled through LG Electronics (not a dedicated solar division). The process is slower than before, but valid claims are still being honoured in most markets, particularly Australia and the US.

How long will LG solar panels last?+

LG NeON panels were among the best-built in the residential market, with a 25-year performance warranty and real-world degradation rates of 0.3โ€“0.4% per year. Many systems will comfortably outlast the warranty period and still produce 85%+ of original output at 25 years.

Should I be worried about my LG solar panels?+

Not about the panels themselves โ€” LG panels are solid. The main concern is warranty service. If panels develop a genuine fault, the claims process is slower and sometimes requires persistence or legal assistance in markets outside South Korea and Australia.

What is the LG NeON degradation rate?+

LG NeON 2 and NeON R panels were warranted to no more than 0.3% annual degradation โ€” well below the industry standard of 0.5โ€“0.8%. Real-world data from independent monitoring confirms these panels hold their output very well over time.

Can I get replacement LG solar panels?+

Not like-for-like. LG stopped manufacturing panels in 2022. If a panel needs physical replacement, you'll need a compatible alternative from another manufacturer. In some cases, your original installer may have sourced spare LG units before the shutdown.

What inverter is compatible with LG solar panels?+

LG panels work with any quality inverter โ€” SolarEdge, Enphase, Fronius, SMA, or Sungrow. The panels produce standard DC electricity; inverter compatibility is about system voltage and current ratings, not brand. Your original installer's choice of inverter is typically the safest to stick with.
