Deductions & credits

I’m in this exact situation. My take on it is this: why would the language in the tax code allow you to carry it forward for *twenty years* if the credit for solar systems placed in service before 2024 was set to expire along with systems installed post-2023? The entire length of the Federal Solar Tax Credit (enacted in 2005) is currently looking to be less than the 20 years cited in the text. Seems pretty clear to me they will grandfather in the rolled over tax credits owed for the 20 years after the credit is claimed. I’m no accountant but it only seems logical. Would love to hear more from an “expert.”
