Frequently Asked Questions

What solar rebates are available to residential homeowners? The 30 percent federal Residential Clean Energy Credit (Section 25D) is available through 2032 and is the largest single solar rebate for most homeowners. State tax credits exist in over 20 states, utility rebates are offered by many investor-owned utilities, and property tax exemptions for solar systems apply in over 30 states. DSIRE (dsireusa.org) tracks all of these by state.

How do homeowners find all available solar rebates in their state? DSIRE (dsireusa.org), maintained by the Interstate Renewable Energy Council, is the most comprehensive and current public database of solar rebates by state. Homeowners should check DSIRE, their utility’s website, and their state energy office — contractor summaries of available incentives are often incomplete or out of date.

Can solar rebates be combined with the federal tax credit? Most solar rebates can be combined with the federal credit, but they may reduce the credit’s calculation basis. Utility rebates excluded from gross income reduce the system’s cost basis by the rebate amount before applying the 30 percent credit. State tax credits and the federal credit can generally be claimed in the same year without offset.

Are solar rebate programs first-come, first-served? Many utility rebate programs are capped — either by total dollars or total megawatts — and close once the cap is reached, sometimes within weeks of opening. The federal Residential Clean Energy Credit is not capped and is available to all eligible taxpayers through 2032. State rebate programs vary widely in their structure and available funding.
