Decision

What the current evidence supports

Human editorial judgment · 2026-08-20

Proceed with caution

Why
Real, credible technical milestone (30.4% internally-tested demo module, first production panel shipped, former US Energy Secretary on board, verified investor backing) but the headline $1B figure is non-binding LOI value, GW-scale manufacturing is 2+ years out, capital raised to date ($87M) is modest relative to the LOI headline, and perovskite-tandem durability/EHS risk remains an unresolved category-wide concern.
Next
Track LOI-to-binding-contract conversion, independent third-party certification (NREL/UL/TUV) results, first-year field degradation data, and progress toward the 2028 GW-scale manufacturing ramp before treating as market-proven.
