I installed and took the full credit for installation of solar panels in 2021.
I now need to install a squirrel guard to protect the underside of the panels from debris, nesting, and wire damage.
I assume that the guard is NOT eligible for the tax credit in 2022, but wanted to see if anyone had advice to the contrary. I guess technically it might count as "balance of system" equipment (like an enclosure). It's not a huge amount of money but wanted to at least check.
