Enphase Energy is trading 4.36% up at $41.40 after the United States announced a 15% tariff and minimum import prices for Chinese polysilicon and downstream solar products.

  • The policy lifts domestic solar manufacturers and related equipment companies; First Solar is gaining sharply premarket and SolarEdge is also advancing.
  • The move appears sector-driven; no fresh Enphase-specific catalyst or reliable volume data was identified for August 7, 2026.
  • The policy is scheduled for December 4, 2026; broader U.S. equity gains were comparatively modest.
