Planning to use TOPCon solar modules on any of your projects? This video breaks down the latest U.S. ITC investigation and how to stay ahead of potential impacts.

On August 15, Treasury and the IRS eliminated the 5% Safe Harbor for most solar and wind projects. Only the Physical Work Test remains (with a limited exception for small solar).

In this video, we break down how Notice 2025-42 will affect solar and wind projects starting on September 2, 2025, which projects continue to qualify for the 5% Safe Harbor Continuity rules, and approaches to satisfy the Physical Work Test.
