Solar Incentives by State
Federal and state incentives, tax credits, rebates, and net metering policies for solar installations (2025).
Federal Investment Tax Credit (ITC) β 30%
Available to all homeowners nationwide through 2032. Reduces your federal income tax by 30% of the total solar installation cost. On a $20,000 system, that's $6,000 off your taxes. Steps down to 26% in 2033, 22% in 2034.

Net Metering
Lets you sell excess solar energy back to the grid, earning bill credits. Available in most states.
Property Tax Exemption
Solar panels increase home value but are excluded from property tax assessment in many states.
Sales Tax Exemption
Some states waive sales tax on solar equipment purchases, saving 5-10% on hardware costs.
Incentive data based on DSIRE database and state energy office publications. Programs change frequently β verify with your state energy office before purchasing.
How to Stack Incentives Without Missing Any
The 30% federal Investment Tax Credit applies to all residential solar through 2032 β worth $7,500 on a $25,000 system. California, Massachusetts, and New York offer additional state credits of $1,000β$5,000. Some utilities add rebates of $0.20β$0.50/watt. Stacking all three can reduce net cost by 40β50% before any net metering savings begin.
The 30% federal Investment Tax Credit is the foundation. It applies to panels, inverters, labor, battery storage, and even the sales tax on those items. There's no maximum dollar cap through 2032. On a $22,000 system, that's $6,600 off your federal tax bill. If you don't owe that much in taxes this year, you can carry the unused portion forward to future years.
State tax credits come next, and the best ones are significant. New York's 25% credit (max $5,000) stacks directly on top of the federal credit. Hawaii offers 35% (max $5,000). Arizona gives 25% (max $1,000). Massachusetts provides 15% (max $1,000) plus their SMART solar program, which pays ongoing credits for electricity generation. All of these combine with the federal ITC.
Property tax exemptions are worth calculating for your situation. Solar panels increase home value by roughly 3β4%, per a 2019 Berkeley Lab study of 22,000 home sales. On a $400,000 home, that's $12,000β$16,000 added value. In a state with a solar property tax exemption (Arizona, Florida, New York, New Jersey, and others), you get that home value increase without paying higher property taxes on it. In a state without the exemption, your taxes go up by roughly $150β$400/year depending on local rates.
Sales tax exemptions matter at installation. A full sales tax exemption on a $20,000 solar system in a state with 8% sales tax saves $1,600 upfront. States with this exemption include Arizona, California, Colorado, Connecticut, Florida, Massachusetts, Nevada, New Jersey, New York, and Washington. Check your state's current status before assuming either way, as programs get added and modified.
Net metering is not a tax credit but it's an ongoing financial benefit. Most states require utilities to credit you at the full retail rate for excess electricity sent to the grid. That credit offsets future bills. In a state with full net metering, a well-sized solar system can reduce your electricity bill to near zero year-round. States that have moved to lower export credit rates (California after NEM 3.0) require larger or battery-paired systems to achieve the same result.
