Provides CBT tax credit for retrofit of existing warehouses with solar-ready zone once solar panels are installed.

This bill provides a tax credit for businesses that retrofit existing warehouses (100,000+ square feet) with designated solar-ready zones, but only after solar panels are installed. The credit covers up to 50% of retrofit costs or $250,000 per warehouse, with a total limit of $25 million across all claims. To qualify, warehouses must meet size requirements, have a solar-ready zone (defined as at least 40% of roof area designated for solar panels), and have panels installed. Businesses must prove panel installation to claim the credit, which applies to up to eight warehouses per tax period.
