@TomD8 - As long as all 4 installs are 'energy saving improvements' why would that not qualify?
Who Can Take the Credits
You may be able to take the credits if you made energy saving improvements to your home located in the United States in
2021.
The credit is a percentage of what you spend in any event....if it was a hard dollar amount for each install (which could create a motivation for multiple installs), then I could see why that would be problematic.
I don't see where in the instructions the number of installs is limited. But the install has to be 'energy saving improvements'. So I could see multiple installs being problematic if the 1st install doesn't yield energy savings, because you don't get to 'critical mass' until the 3rd install, both assuming each install creates 'energy savings improvements', why can't someone take the credit?
