@Critter-3 -
The original thread discusses the Investment Tax credit, not the residential energy credit - so I wonder if there is some confusion here. I am assuming that @louvallee is asking about installing solar on his personal residence.
the 5695 instructions have this warning on page 1:
"IRS guidance issued with respect to the energy credit under section 48, such as Notice 2018-59, does not apply to the residential energy credits.
so if the question is about the solar residential credits, here are my comments:
here are the 2022 instructions and form that incorporates the new tax law related to the residential tax credit;.

https://www.irs.gov/pub/irs-dft/f5695--dft.pdf
1) The credit is earned in the year of the install. I can find no documentation that supports the credit can be carried back to a prior tax year.
2) Form 5695 nor the instructions makes amy menton of limits on the number of years the unused credit can be carried forward. Even the TT article doesn't reference a limit In fact, I can find no documentation that once the solar is installed, there is no reason the credit can't be carried forward until death, meaning the tax liability over time is so low that credit can't be consumed.

3) Per the instructions, the credit is available on all installations through 2034. If planning to INSTALL solar in 2035, do not assume there will be a solar tax credit. It doesn't mean that if an installation occured prior to 2035 and the credit wasn't consumed on a tax return, it expires. So the 10 year limit is the opportunity to install and get a credit, not that the credit has to be consumed in 10 years.
Personally, I like to reference IRS and other federal gov't websites as the truth; I can not find support on the IRS website, the 5695 instructions or the 5695 form that supports a number of ascertions at this link and would not consider this reference as credible.

sorry if I am being overly direct.....
