Why it's on ClimateTicker

Meyer Burger manufactures high-efficiency heterojunction (HJT) solar cells and modules, meaning its core product genuinely displaces fossil-fuel electricity generation — a clear mitigation play. However, the company collapsed into insolvency in 2025 (Chapter 11 in the US, debt moratorium in Switzerland, German subsidiaries insolvent), wiping out its manufacturing base and calling into question whether any near-term climate impact will actually be delivered. Investors should treat this as a cautionary tale of a genuine clean-tech vision that failed on execution and capital structure, not on mission.

mitigationMeyer Burger sold premium HJT solar cells and modules to residential, commercial, and utility customers, differentiating on higher efficiency and European provenance; revenue depended heavily on a small number of large offtake agreements (notably a 5 GW deal with DESRI) and US Inflation Reduction Act Section 45X manufacturing credits.
