State Clean Energy Incentives: A Guide Beyond Federal Tax Credits

The federal residential solar tax credit is gone. After years of offering homeowners a 30 percent deduction on solar installation costs, the Section 25D credit expired at the end of 2025. If you have been putting off clean energy upgrades because you were counting on that federal incentive, you might think the window of opportunity has closed.

It has not. State clean energy incentives remain robust across much of the country, and in many cases they are worth thousands of dollars in savings that homeowners overlook entirely. From state tax credits and upfront rebates to Solar Renewable Energy Certificates that pay you for every megawatt-hour your panels produce, the state-level landscape is rich with opportunity. The key is knowing where to look and how to stack these programs for maximum benefit.

If you are still getting oriented on the federal side, our complete guide to IRA clean energy tax credits covers what remains available. This article focuses on everything your state government, local programs, and regional markets offer beyond that.

Why State Incentives Matter More Than Ever

For most of the past decade, the federal tax credit was the headliner. It was simple, universal, and generous: install solar, get 30 percent back on your taxes. State programs were a nice bonus but rarely the deciding factor.

That dynamic has flipped. With the federal residential credit gone, state incentives are now the primary financial lever for homeowners considering solar panels, battery storage, heat pumps, and other clean energy improvements. And here is the thing many people do not realize: some state programs are worth more than the federal credit ever was.

South Carolina, for example, offers a 25 percent state tax credit with a maximum of $35,000 spread over 10 years. On a large solar-plus-battery installation, that can exceed what the federal credit would have provided. New York combines a state tax credit, per-watt incentive payments, and full property tax exemption that together can cover more than half the project cost.

The catch is that state programs vary enormously. What is available in Massachusetts looks nothing like what is available in Texas. That is why understanding the landscape and using the right tools to find your specific opportunities is so important.

The DSIRE Database: Your Starting Point

Before diving into specific states, you need to know about DSIRE, the Database of State Incentives for Renewables and Efficiency. Operated by the N.C. Clean Energy Technology Center at NC State University since 1995, DSIRE is the most comprehensive free resource for finding clean energy incentives at every level: federal, state, local, and utility.

Visit dsireusa.org, enter your state or zip code, and you will get a complete list of every incentive, rebate, tax credit, loan program, and regulatory policy available in your area. The database covers solar, wind, geothermal, energy efficiency, electric vehicles, and more. It is updated regularly and is the single best starting point for any homeowner exploring clean energy.

Top States for Clean Energy Incentives in 2026

While every state has something to offer, some stand out for the depth and generosity of their programs. Here are the states where incentives can make the biggest financial difference in 2026.

New York

New York may be the single best state for residential clean energy incentives right now. The combination of programs can cover more than half your project cost.

The state offers a 25 percent income tax credit worth up to $5,000 on your New York state taxes. On top of that, the NY-Sun program provides incentive payments of $0.20 to $0.40 per watt for residential solar installations, which translates to $1,200 to $2,400 off a typical 6-kilowatt system. Solar installations are exempt from property tax increases for 15 years, and you pay no sales tax on solar equipment. Net metering credits at full retail rates round out the package.

Add it all up and a $30,000 solar installation in New York could see $8,000 to $10,000 in combined state incentives before any utility-specific programs are factored in.

South Carolina

South Carolina's state solar tax credit is one of the most generous in the country: 25 percent of qualified costs with a maximum of $35,000 over 10 years. That cap is exceptionally high compared to other states and makes South Carolina competitive even without a federal credit.

The credit is spread over multiple tax years, so you do not need a massive tax liability in a single year to take full advantage. For homeowners with larger installations or solar-plus-battery systems, South Carolina's program can be a game-changer.

Massachusetts

Massachusetts takes a layered approach. The state tax credit covers 15 percent of system costs up to $1,000, which is modest on its own. But the real value comes from the SMART program, which pays you a fixed rate for every kilowatt-hour your system produces over a 20-year period. In 2026, the base residential SMART rate is approximately $0.03 per kilowatt-hour, and that payment comes on top of whatever you save on your electric bill.

Massachusetts also maintains one of the strongest SREC markets in the country, with certificates historically trading around $271 per megawatt-hour. Both property tax and sales tax exemptions apply to solar installations. Between SMART payments, SRECs, tax exemptions, and electricity savings, Massachusetts homeowners can see excellent returns.

New Jersey

New Jersey does not offer a direct state tax credit, but its incentive structure is among the most valuable anywhere. The Successor Solar Incentive Program, known as SuSI, provides performance-based payments tied to your system's actual energy production.

Under the SREC-II program, homeowners earn $85 for every megawatt-hour their system produces, locked in for 15 years. A typical 6-kilowatt residential system generating 8 megawatt-hours per year would earn about $680 annually, or over $10,000 across the full 15-year term.

New Jersey also offers full one-to-one retail-rate net metering at approximately $0.26 per kilowatt-hour, which is among the highest electricity rates in the nation. Higher rates mean bigger savings from each kilowatt-hour of solar you generate. Property and sales tax exemptions apply as well.

Illinois

Illinois operates the Illinois Shines program through its Adjustable Block Program, providing SREC-based incentives worth $10,000 to $12,000 over 15 years for a typical residential system. Solar installations are also exempt from property tax increases.

The Illinois market is particularly attractive because the SREC payments are relatively predictable, giving homeowners a clear picture of their long-term returns.

Oregon

Oregon takes a different approach with its Solar + Storage Rebate Program. Instead of tax credits or performance payments, Oregon offers upfront rebates: up to $5,000 for solar installations and $2,500 for battery storage. Higher rebates are available for low-income households.

The rebate format is appealing because you receive the money directly rather than waiting for tax season. Combined with Oregon's relatively high electricity rates and good solar resource in the eastern part of the state, these rebates make solar competitive.

California

California does not offer a state income tax credit for solar, but it remains an important market thanks to the Self-Generation Incentive Program, which provides rebates of $150 to $1,000 per kilowatt-hour for battery storage. Solar installations are excluded from property tax assessments.

The big caveat in California is the shift from NEM 2.0 to the Net Billing Tariff, which significantly reduced the value of surplus solar electricity exported to the grid. This makes battery storage more important in California than almost anywhere else, and it is why the SGIP battery rebate matters so much.

If you are considering solar in California, pairing it with a home battery is practically essential for maximizing your return.

Understanding SRECs: Getting Paid for Your Solar Production

Solar Renewable Energy Certificates, or SRECs, are one of the most valuable but least understood state incentives. If your state has an SREC market, your solar panels could be generating hundreds or even thousands of dollars in additional income every year.

Here is how they work. Many states have Renewable Portfolio Standards that require electric utilities to source a certain percentage of their electricity from solar. To prove compliance, utilities need SRECs. Your solar system earns one SREC for every megawatt-hour (1,000 kilowatt-hours) of electricity it produces. You can then sell that certificate to a utility or broker.

The price of an SREC depends on supply and demand within each state's market. In New Jersey, legacy SRECs trade at around $175 each. In Massachusetts, they have historically traded above $270. The market is capped by the Solar Alternative Compliance Payment, which is the penalty utilities pay if they cannot acquire enough SRECs, effectively setting a price ceiling.

For a typical 6-kilowatt residential system producing 7 to 9 megawatt-hours per year, SREC income could range from $600 to over $2,400 annually depending on your state's market. Over a 15-year period, that adds up to significant money.

States with active SREC markets include New Jersey, Massachusetts, Maryland, Illinois, Ohio, Pennsylvania, and Washington, D.C. If you live in one of these states, SRECs are a major part of the financial case for solar.

IRA Rebate Programs: HOMES and HEAR

While the federal tax credit for homeowners is gone, two rebate programs from the Inflation Reduction Act are still rolling out across the country. These are not tax credits. They are direct rebates, often applied at the point of sale.

The HOMES program (Home Efficiency Rebates) rewards whole-home energy efficiency improvements. If your upgrades achieve at least 35 percent energy reduction, you could qualify for up to $8,000 in rebates.

The HEAR program (Home Electrification and Appliance Rebates) provides fixed-dollar rebates on specific equipment like heat pumps, heat pump water heaters, and electrical panel upgrades. HEAR rebates are income-dependent: up to $14,000 for households at or below 80 percent of area median income, up to $7,000 for households between 80 and 150 percent AMI, and nothing for those above 150 percent.

The catch is that rollout has been uneven. As of March 2026, states like Wisconsin, New Mexico, Rhode Island, and Michigan have both programs live. Others, like Connecticut, New Hampshire, and Washington, are still in the launch process. California's HEEHRA program is already fully reserved with a waitlist.

Other State Incentive Types You Might Be Missing

Beyond the headline programs, states offer several other incentive types that can chip away at your costs.

Property tax exemptions are available in most states with significant solar adoption. They prevent your property taxes from increasing based on the added value of your solar installation. Since a solar system can add $15,000 to $30,000 in home value, this exemption saves you hundreds of dollars per year in avoided tax increases.

Sales tax exemptions eliminate the state sales tax on solar equipment purchases. In states with sales tax rates of 6 to 8 percent, that saves $1,200 to $1,600 on a $20,000 equipment purchase.

Low-interest loan programs offered by state energy offices or green banks provide financing at below-market rates, sometimes as low as 2 to 4 percent.

Community solar incentives benefit renters and homeowners whose roofs are not suitable for solar. Many states have programs that make subscribing to a community solar project financially attractive. Our guide to community solar covers how these work.

How to Find and Maximize Your State's Programs

Finding every available incentive requires checking multiple sources. Here is a step-by-step approach.

Step 1: Start with DSIRE. Visit dsireusa.org and search by your state and the technology you are considering. This gives you the broadest view.

Step 2: Check your utility's website. Many utilities offer their own rebates on top of state programs. Look for a "rebates," "incentives," or "energy savings" section. Our guide to utility rebate programs covers this in detail.

Step 3: Use the ENERGY STAR Rebate Finder. Visit energystar.gov/rebate-finder and enter your zip code to find rebates on ENERGY STAR certified products from utilities, states, and manufacturers.

Step 4: Contact your state energy office. Every state has one, and they often publish consolidated guides to available programs.

Step 5: Get multiple installer quotes. Reputable solar installers should identify every incentive you qualify for. Getting at least three quotes ensures nothing is missed. Services like EnergySage let you compare bids with incentive calculations included.

Step 6: Ask about stacking. Many incentives can be combined. A state tax credit, an SREC program, a utility rebate, and a property tax exemption can all apply to the same installation. Make sure your installer and tax advisor help you maximize the stack.

The Bottom Line

The federal solar tax credit may be gone, but the state incentive landscape is deep, varied, and genuinely valuable. In the best states, combined incentives can cover 30 to 50 percent or more of your project cost. In states with SREC markets, ongoing payments add thousands of dollars in value over the life of your system.

The key is doing your homework. Use DSIRE, check your utility, explore your state's specific programs, and get multiple quotes. The money is there for homeowners who take the time to find it.
