State Solar Incentives by State — Full 2026 Guide

2026 update: The federal 30% Investment Tax Credit (Section 25D) expired for homeowner-purchased systems on December 31, 2025. There is no federal solar tax credit for new purchased residential systems in 2026. State-level incentives are now your only tax-based financial support — and the variation between states has never mattered more.

Depending on where you live, your state might offer thousands of dollars in rebates, performance payments, or property tax exemptions. In strong incentive states like New York, Massachusetts, and New Jersey, these programs partially compensate for the loss of the federal credit. In states with no incentives, you are paying full price.

The problem is that every state is different, the rules change frequently, and most of the information online is either outdated or buried in government PDFs nobody reads. This guide compiles the current status for all 50 states as of March 2026.

How State Incentives Work (Quick Overview)

Before diving into the state-by-state breakdown, here is what you need to understand about the categories of state incentives:

State Tax Credits — Some states offer their own income tax credit for solar installations, separate from the federal ITC. These can range from a few hundred dollars to $5,000 or more. You claim them on your state tax return.

Cash Rebates — Some states or utilities pay you a direct cash rebate per watt of solar installed. A $0.50/watt rebate on a 10kW system is $5,000 back in your pocket.

Net Metering — When your panels produce more electricity than you use, the excess goes back to the grid. Net metering policies determine how much you get credited for that excess. Full retail-rate net metering (you get credited at the same rate you pay) is the gold standard. Some states have reduced this to wholesale rates or added fees.

Property Tax Exemptions — Solar panels increase your home value. Some states exempt that added value from property taxes, so your tax bill does not go up even though your home is worth more.

Solar Renewable Energy Credits (SRECs) — In states with SREC markets, you earn tradable credits for every megawatt-hour your system produces. These can be worth $20 to $400+ per credit depending on the state market.

Performance Payments — Some utilities pay you per kilowatt-hour your system produces, regardless of whether you use the electricity or send it to the grid.

Top 10 States for Solar Incentives in 2026

1. New York

New York stacks incentives better than almost any other state. The NY-Sun Megawatt Block incentive provides $0.20–$0.40/watt in upfront rebates depending on your utility territory and the current block. The state also offers a 25% state tax credit (up to $5,000), full retail-rate net metering, and a property tax exemption for the added home value. Even without the expired federal ITC, a $28,000 system in New York can realistically reach under $18,000 after state incentives — making it one of the most cost-effective states for solar in 2026.

2. California

California shifted from its legacy NEM 2.0 net metering to NEM 3.0 in 2023, which significantly reduced the value of exported solar energy. However, the state still offers strong incentives: the Self-Generation Incentive Program (SGIP) provides rebates for battery storage (up to $1,000/kWh), and the state's high electricity rates ($0.30–$0.45/kWh) mean solar still delivers dramatic savings even under the new rules. If you pair solar with a battery, California remains one of the best states for total savings.

3. Massachusetts

The SMART program pays solar owners per kilowatt-hour produced for 10 years. Rates vary by utility and project size but typically range from $0.06–$0.12/kWh. Combined with net metering and a state income tax credit of up to $1,000, Massachusetts homeowners see some of the shortest payback periods in the country — the state's high electricity rates ($0.27–$0.30/kWh) make the economics work even without the federal ITC.

4. New Jersey

New Jersey's Successor Solar Incentive (SuSI) program creates tradable renewable energy certificates worth approximately $85–$100 each for the first 15 years of your system's life. A 10kW system producing 12 MWh/year generates 12 SRECs worth roughly $1,020–$1,200 annually. Property tax exemption and sales tax exemption are also in effect.

5. Connecticut

The Residential Solar Investment Program provides upfront incentives, and Connecticut offers full retail net metering, a property tax exemption on the added value, and sales tax exemption on solar equipment. The combined value typically reduces total system cost by 45–55%.

6. Maryland

Maryland offers a $1,000 state tax credit, property tax exemption, and an active SREC market where credits trade at $60–$80 each. Net metering is available at retail rates. The state also has a sales tax exemption on solar equipment.

7. Illinois

The Adjustable Block Program provides upfront payments for SRECs. Residential systems typically receive $3,000–$5,000 in SREC value. The state also offers net metering at full retail rates and a property tax exemption.

8. Rhode Island

Renewable Energy Growth (REG) program provides fixed payments per kWh for 15–20 years. Rates are competitive, and combined with net metering, Rhode Island homeowners see payback periods of 5–8 years even without the federal ITC.

9. Minnesota

The state offers a solar energy production incentive of $0.06–$0.08/kWh for 10 years, property tax exemptions, and favorable net metering policies. Xcel Energy customers have access to additional rebate programs.

10. Colorado

Colorado offers strong net metering at full retail rates, property tax exemptions, and some utility-specific rebate programs. Denver and Boulder have additional local incentives that can add $1,000–$2,000 in savings.

States With Weak or No Incentives

Not every state makes solar easy. These states have minimal state-level support beyond the federal ITC:

• Alabama — No state tax credit, no SREC market, limited net metering
• Mississippi — No state incentives, no mandatory net metering
• Idaho — No state tax credit, net metering available but no additional incentives
• West Virginia — No state solar incentives, coal-focused energy policy
• Wyoming — No state tax credit, no SREC market

In these states, you have no tax-based financial support at all — the federal ITC expired January 1, 2026, and there are no state credits to fall back on. Solar can still make financial sense if your electricity rates are high enough and your roof gets good sun exposure, but payback periods will be 14–20+ years. A lease or PPA (where the installer claims the Section 48E commercial credit) may be a better option than purchasing in these states.

How to Find Your Exact Incentives

The best way to get accurate, current incentive information for your specific address is through the Database of State Incentives for Renewables and Efficiency (DSIRE) at dsireusa.org. This is maintained by NC State University and is the most comprehensive database of solar incentives in the country.

For a more practical approach, solar marketplace platforms pull this data automatically when you enter your address and generate quotes.

Key Takeaways

• The federal 30% ITC expired January 1, 2026 for purchased residential systems — state incentives are now the only tax-based financial support available
• SREC markets (NJ, MA, MD, IL) provide ongoing income for years after installation
• Net metering policy is the single most important state-level factor for long-term savings
• Property tax exemptions exist in most top solar states — do not overlook this benefit
• Always check your specific utility's programs in addition to state-level incentives

State incentive programs change frequently. Budgets get exhausted, programs get renewed with different terms, and utility-specific programs rotate. The best time to research is when you are actively considering solar, not months in advance.
