The solar credit does not offset self-employment tax, only income tax. And I believe it does not offset certain other schedule 2 taxes . . .
That's correct. The only taxes on Schedule 2 that can be offset by the solar credit, or any other nonrefundable credit, are AMT and repayment of excess advance premium tax credit. Those two additional taxes are in Part I of Schedule 2. The nonrefundable credits do not offset any of the taxes in Part II of Schedule 2 (lines 4 through 20), which includes all of the taxes that Opus 17 listed.
I slightly revised my reply above to refer specifically to income tax.
