## Summary

LG is a South Korean electronics conglomerate that began solar research in 1985 and spent over three decades cultivating a premium reputation in the residential panel market. In June 2022, LG exited solar manufacturing entirely, citing supply chain disruptions and rising logistics costs, and the company no longer appears on BloombergNEF's active Tier 1 module manufacturer list. Trina Solar, by contrast, was founded in December 1997 in Changzhou, Jiangsu Province, China, and has since grown into one of the three largest solar manufacturers globally by shipment volume. With over 205 GW of cumulative deliveries across more than 100 countries, annual production capacity exceeding 80 GW, and consistent BNEF Tier 1 bankability recognition - including topping the rating for the eighth time and maintaining the status through Q1 2025 - Trina Solar's institutional footprint is in a different league compared to LG's now-legacy standing.

LG's product legacy centered on the NeON series - NeON 2 and NeON R - which used N-type and IBC cell technology to achieve module efficiencies of up to 22.3%, making them a favored choice for space-constrained residential rooftops. Those panels are now available only through the secondary market, and warranty claims on existing installations typically result in cash settlements rather than direct panel replacement, since manufacturing stock has been exhausted. Trina Solar's active portfolio spans two main families: the large-format Vertex series, built on 210 mm wafers with N-type i-TOPCon cells and aimed primarily at utility-scale ground-mount and commercial C&I applications, and the Vertex S+ series, a smaller-format option for residential and commercial rooftop projects that also uses TOPCon technology. Current production models reach efficiencies of around 22.5%, and in March 2026 Trina unveiled a 485 W TOPCon module rated at 24.3% efficiency, signaling continued active R&D investment.

For any buyer planning a new installation today, this comparison is effectively decided before it begins: LG panels are no longer manufactured and cannot be purchased new, leaving Trina Solar as the only active option of the two. Trina suits both residential buyers seeking a proven, bankable brand with long-term supply security and project developers requiring utility-scale volumes. Owners of existing LG systems can expect reliable ongoing performance - LG's legacy modules were well-engineered products - but should be aware that like-for-like warranty replacements may no longer be possible.
