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.

Common issues with LG Solar
Natural panel degradation
All solar panels lose efficiency over time at roughly 0.5–0.8% per year. Accelerated in extreme heat or poorly manufactured panels.
Typical loss: 3–15%
Cell hotspots
Localised overheating in individual cells caused by micro-cracks, shading, or manufacturing defects. Best detected via thermal imaging.
Typical loss: 5–20%
