Solar Tax Credits and Incentives in 2026
Updated September 22, 2026
Federal residential clean energy credit
The IRS states that the Residential Clean Energy Credit (Section 25D) is not available for property placed in service after December 31, 2025. Do not assume that a new 2026 residential solar or battery installation receives a 30% federal credit.
For eligible earlier installations, consult the IRS instructions for the relevant tax year and any carryforward rules. Business-owned projects follow separate rules and require a project-specific review.

Check incentives for your actual address
State, local and utility programs differ. Use the DSIRE incentive directory to find potential programs, then confirm the current terms directly with the program administrator or your utility.
- Check that your equipment, installation date and ownership type qualify.
- Confirm whether off-grid systems are eligible; export credits require an eligible grid connection.
- Check funding availability, application deadlines and any pre-approval requirement.
- Use only confirmed incentives in a purchase budget.
