Solar panel tax credit taken but panels subsequently removed -ould

We had solar panels installed and took the solar tax credit in the year in which the panels were installed, paid for, and made operational.  The panels never worked as intended and the company could not address the issue, so they agreed to remove the panels and give us ‘most’ of our money back.  How do I make this right with the IRS?  I don’t want to do an amended return for the prior year, because we did indeed meet all of the qualifications for taking the solar credit. But I haven’t found anything in the IRS directives, instructions, or other materials to indicate what to do in this situation.
