I did see that announcement yesterday of the decision from the IRS, but if you read it closely, it applies only to Dept of Energy rebates (i.e., the IRA rebate program, which was awaiting this guidance) - which mine isn't. In fact, all of the links you offered refer specifically to the IRA and don't mention any other rebate program.
I suppose I can take a chance based on their prior decisions and just pay up if they challenge my reasoning! Thanks for your follow-up.
