This TP appears to be eligible for an additional 10% tax credit because he installed solar at his home in West Virginia.  He operates a farm on his property.  According to  https://www.solarholler.com, 52 out of 55 counties in West Virginia can take advantage of the "Energy Community" tax credit, meaning most nonprofits and businesses in the state will see their tax credit jump from 30% to 40%.

I'm just not sure where to claim this additional 10% tax credit or what documentation may be needed to support.
