If you do not expect to owe enough in taxes this year to claim the full credit, you can roll over your federal solar tax credit to the following year. You should consult your tax professional with any questions, although most online e-filing services allow you to easily record your system cost and claim the tax credit. You don’t need to provide any payment receipts or supporting documentation unless requested specifically by the IRS. IRS Form 5695, Residential Energy Credits, and instructions are located here.
