I am reading that the IRS applies the rebate for solar energy installation before that of a new EV. So if you got both in the same tax year, any excess rebate will not carry forward to the next year (assuming the excess comes from the EV). ie. If you have a $10,000 tax liability and a $5000 rebate for solar and $7500 for a new EV, the remaining $2500 rebate would be lost because it theoretically came from the EV since the solar is applied first.
Am I understanding this correctly?
