I agave the same situation except that in my situation the Roof was replaced in 2021 and the solar panels installed in 2022 (the solar panels couldn’t be installed in the older roof as it was deemed too old for that). Can I still include the roof replacement cost of 2021 as part of the 2022 solar panel cost/credit? (Notice the year difference). Also if I have claimed the roof by itself in the 2021 return ($500 credit as part of the home energy improvement credit) should I file an amendment to the 2021 to remove it from there since it’s now accounted for in the 2022 solar credit?
