While it's correct that it gets applied first the CTC is 100% refundable this year and next year. So I'm assuming the solar would still take in affect. I mocked it up in my 2020 filing and that seemed to be the case.
The Additional CTC was the refundable part of the CTC. But because it's 100% now I don't believe that applies for the next two years.
I'm not a tax advisor but that's how I'm interpreting it.
