Beyond the federal tax credit, many states offer their own incentives that can slash your solar costs even further. These programs vary widely in type and value — some states are incredibly generous, while others offer minimal support. Here’s a guide to navigating state-level solar incentives.
Types of State Solar Incentives
State tax credits work like the federal ITC but reduce your state income tax. States like Arizona, New Mexico, South Carolina, and others offer credits ranging from 10% to 35% of system cost.
Cash rebates provide upfront money back after installation. These are often funded through utility companies or state energy offices and can range from a few hundred to several thousand dollars.
Solar Renewable Energy Certificates (SRECs): In states with Renewable Portfolio Standards, solar system owners earn certificates for each megawatt-hour of solar electricity produced. These certificates can be sold on SREC markets. In states like New Jersey, Massachusetts, and Maryland, SRECs can add $50–$200+ per year in income.
Performance-based incentives pay you a per-kWh rate for the electricity your system produces, typically for 10–20 years. These ongoing payments significantly boost your financial return.
Property tax exemptions prevent your property taxes from increasing despite the added value of a solar installation. Over 35 states offer some form of this exemption.
Sales tax exemptions remove state sales tax from solar equipment purchases, saving 4–10% on your system cost depending on your state’s sales tax rate.
Top States for Solar Incentives
Massachusetts: Combines the federal ITC with state SMART incentive payments, SRECs, property tax exemption, and sales tax exemption. One of the most lucrative states for solar.
New York: Offers a state tax credit (25% up to $5,000), NY-Sun rebates, net metering, and property tax exemption. Strong net metering makes solar very attractive.
New Jersey: Excellent SREC program, property tax exemption, sales tax exemption, and robust net metering. A consistently top-tier solar state.
California: While net metering has changed under NEM 3.0, the Self-Generation Incentive Program (SGIP) provides battery storage rebates, and the state’s high electricity rates still make solar plus storage very economical.
How to Find Your State’s Incentives
The best resource is the Database of State Incentives for Renewables and Efficiency (DSIRE) at dsireusa.org. This comprehensive database lists every federal, state, local, and utility incentive available at your address.
Your solar installer should also be knowledgeable about local incentives and factor them into your proposal. If they’re not, it’s a red flag about their expertise.
Don’t Leave Money on the Table
Many homeowners miss out on incentives they’re entitled to simply because they didn’t know about them. Before finalizing your solar decision, research every available incentive at the federal, state, local, and utility level. Stacking multiple incentives can reduce your effective system cost by 40–60%.
