Meyer Burger vs Trina Solar - solar panel manufacturer comparison

Meyer Burger is a Swiss company with roots dating to 1953, originally a precision machine manufacturer that repositioned itself as a solar panel producer built around heterojunction technology (HJT). Its modules - combining crystalline silicon with thin amorphous silicon layers - earned strong reviews for an exceptionally low annual degradation rate of around 0.25% after the second year, as well as competitive low-light performance, making them a preferred premium option for residential rooftop installations across Europe and the United States. However, in 2025 the company's operations collapsed entirely: its Goodyear, Arizona factory shut down in May, German subsidiaries filed for insolvency, and the US holding company entered Chapter 11 bankruptcy protection in June 2025. By autumn 2025, substantially all assets had been liquidated and sold to Waaree Solar Americas for approximately $18.5 million, effectively ending Meyer Burger's existence as an independent manufacturer. Trina Solar, founded in 1997 and headquartered in Changzhou, China, presents an entirely different picture. The company had accumulated over 275 GW in cumulative module shipments by early 2025 and holds BloombergNEF Tier 1 status confirmed in Q2 2025, reflecting both its financial bankability and massive production scale. Trina Solar's institutional footprint is substantially larger and fully operationally intact.

Meyer Burger's HJT technology was particularly well suited to residential and small commercial applications where longevity and yield in diffuse light conditions mattered most. With the company no longer operating as a going concern, warranty continuity and aftermarket support carry meaningful risk for any buyer holding existing panels. Trina Solar's current portfolio centers on n-type TOPCon technology: the Vertex S+ series covers residential rooftop and commercial and industrial (C&I) projects, while larger-format modules reaching 760 W with 24.5% conversion efficiency target utility-scale ground-mount installations. Trina has earned PVEL Top Performer recognition for eleven consecutive years and backs residential modules with a 25-year product and 25-year power warranty through its TrinaProtect programme.

For buyers assessing these two brands in 2026, the comparison is essentially one-sided. Meyer Burger no longer functions as an independent manufacturer, and any panel relying on its warranty infrastructure carries real service and continuity risk. Trina Solar is the clear default recommendation for residential, commercial, and utility buyers seeking bankable warranties, reliable supply chains, and a stable global support network. The only context in which existing Meyer Burger HJT panels might still appeal is a secondhand acquisition at a steep discount - one where the buyer consciously accepts warranty uncertainty in exchange for the technology's strong inherent performance characteristics.
