(The 30% federal tax credit won’t last forever.) Here’s what you can save:
Today: A $20,000 solar system generally qualifies for a $6,000 federal tax credit (30% ITC).
Potential Bonus: You might also qualify for an additional 10% bonus (worth $2,000 on a $20k system) – such as the Domestic Content or Energy Community bonus – if your project meets the specific IRS requirements for that particular bonus (e.g., using sufficient U.S.-made parts or being in a designated location). Potential Total Savings:
This could bring total savings up to $8,000, but achieving the bonus portion depends entirely on meeting those specific criteria.
