Solar Incentives & Tax Credits 2026: Federal ITC, State Rebates & Net Metering

Federal Investment Tax Credit (ITC)

The federal solar Investment Tax Credit is the largest single incentive available to solar buyers in 2026. Under the Inflation Reduction Act (IRA), signed into law in August 2022, the ITC provides a 30% tax credit on the total cost of a solar energy system installed on your home or business. This credit applies to systems placed in service from 2022 through 2032.

The ITC is a dollar-for-dollar reduction in your federal income tax liability, not a deduction. If your solar system costs $25,000 and you claim the 30% ITC, you receive a $7,500 credit that directly reduces the taxes you owe. If you owe $10,000 in federal taxes, the credit reduces your tax bill to $2,500. If your tax liability is less than the credit amount, the unused portion carries forward to the following tax year — there is no expiration on the carryforward.

The ITC schedule under the Inflation Reduction Act is as follows: 30% from 2022 through 2032, stepping down to 26% in 2033, 22% in 2034, and expiring for residential systems in 2035. For commercial systems, a permanent 10% credit remains after the step-down. This generous timeline gives homeowners several years to go solar at the full 30% credit, but acting sooner maximizes savings due to rising electricity rates. Use our Solar Panel Calculator to estimate your system size and calculate the ITC amount.

ITC Eligibility, Rules & How to Claim

To claim the federal solar ITC, you must meet several requirements. The solar energy system must be installed on property you own (primary residence, second home, or commercial building). Leased systems and power purchase agreements (PPAs) do not qualify — the company that owns the system claims the credit instead, theoretically passing savings to you through lower lease rates.

The ITC covers a wide range of costs associated with your solar installation. Eligible expenses include solar panels and mounting hardware, inverters (string or micro), battery storage systems (no minimum solar requirement since 2023), electrical wiring and conduit, installation labor, permit and inspection fees, sales tax on equipment, energy monitoring systems, and even the cost of the roof portion directly supporting the panels if structural upgrades are needed.

To claim the credit, file IRS Form 5695 (Residential Energy Credits) with your federal tax return for the year the system is placed in service. "Placed in service" means the system is installed, inspected, and operational — not the date you signed a contract or made a payment. Keep all receipts, contracts, and proof of installation costs in case of an IRS audit. Your installer should provide a detailed invoice breaking down equipment and labor costs, which is the primary documentation needed.

State Tax Credits and Rebates

Many states offer additional solar incentives that stack on top of the federal ITC, further reducing your net cost. These come in several forms: state income tax credits, upfront rebates, property tax exemptions, and sales tax exemptions. The combination can reduce your total solar cost by 40-60% in the most generous states.

State Tax Credits

Several states offer their own solar tax credits in addition to the federal ITC. Notable examples include South Carolina (25% state credit, no cap), New York (25% credit, up to $5,000), Arizona (25% credit, up to $1,000), Massachusetts (15% credit, up to $1,000), and Maryland ($1,000 flat credit). Unlike state rebates, state tax credits do not reduce the cost basis for the federal ITC calculation, meaning you get the full benefit of both.

Upfront Rebates

Some states and utilities offer cash rebates based on system size. These are typically paid per watt of installed capacity. Examples include Connecticut ($0.25-$0.43/W through the RSIP program), Florida (various utility programs), and numerous utility-specific programs across the country. Note that state rebates reduce the cost basis used to calculate the federal ITC. If your $25,000 system receives a $2,000 state rebate, the federal ITC is calculated on $23,000 (30% = $6,900) rather than the full $25,000.

Property Tax Exemptions

Solar panels increase your home's value, which could increase your property taxes. Fortunately, over 35 states offer property tax exemptions for solar installations, meaning the added value from solar panels is excluded from your property tax assessment. In a state with a 1.5% property tax rate, a $20,000 solar system exemption saves $300 per year in perpetuity — a significant ongoing benefit. Our Solar Savings Calculator factors in property tax exemptions when calculating your total solar ROI.

Net Metering Policies by State

Net metering is the billing mechanism that determines how much credit you receive for excess solar electricity exported to the grid. The value of net metering can make or break the financial case for solar, making it one of the most important incentives to evaluate.

As of 2026, net metering policies fall into three categories. Full retail-rate net metering credits your exported electricity at the same rate you pay to buy electricity — this is the most favorable policy and is available in approximately 30 states including New York, New Jersey, Massachusetts, Ohio, and Illinois. Reduced-rate net metering credits exports at a lower rate, typically 50-80% of the retail rate, as seen in states transitioning away from full net metering. Net billing provides wholesale or avoided-cost credits for exports, typically $0.03-$0.08 per kWh — California's NEM 3.0 (effective April 2023) is the most prominent example, crediting exports at roughly $0.05/kWh compared to retail rates of $0.30-$0.45/kWh.

In states with poor net metering, pairing solar with battery storage becomes essential for maximizing savings. A battery lets you store excess solar power and use it during peak rate periods rather than exporting it at low credit rates. This self-consumption strategy recovers the value that weak net metering would otherwise forfeit.

Solar Renewable Energy Certificates (SRECs)

SRECs are tradeable certificates generated by your solar energy system — one SREC for every megawatt-hour (1,000 kWh) of electricity produced. Utilities in certain states must purchase SRECs to meet their Renewable Portfolio Standard (RPS) requirements, creating a market where solar system owners can sell their certificates for additional income.

SREC values vary dramatically by state, driven by supply and demand dynamics. In states with aggressive RPS mandates and limited solar capacity, SREC prices can be substantial. As of early 2026, approximate SREC prices are: New Jersey at $150-$200 per SREC, Massachusetts at $200-$280 per SREC (through SMART program), Washington D.C. at $300-$400 per SREC, Maryland at $40-$60 per SREC, Pennsylvania at $20-$35 per SREC, and Ohio at $5-$10 per SREC.

For a typical 7 kW residential system producing about 9 MWh per year, annual SREC income would be $1,350-$1,800 in New Jersey, $1,800-$2,520 in Massachusetts, or $2,700-$3,600 in Washington D.C. Over a 10-year period, SREC income can exceed $15,000-$30,000 in the best markets — sometimes more than the net cost of the system itself. To sell SRECs, you register your system with your state's SREC tracking platform (such as GATS, PJM-GATS, or NEPOOL-GIS) and sell through an SREC aggregator or on the open market. Use our Solar Payback Calculator to factor SREC income into your solar investment analysis.

MACRS Depreciation for Businesses

Businesses, farms, and commercial property owners have access to the Modified Accelerated Cost Recovery System (MACRS), which allows them to depreciate solar energy assets over 5 years. Combined with bonus depreciation (currently 60% in 2026, stepping down from 80% in 2025 and 100% in 2022-2023), MACRS provides substantial additional tax benefits beyond the ITC.

Here is how it works for a $100,000 commercial solar installation in 2026. First, apply the 30% ITC, reducing the depreciable basis by half the ITC amount: $100,000 - $15,000 = $85,000 depreciable basis. Then apply 60% bonus depreciation in year one: $51,000 deducted immediately. The remaining $34,000 is depreciated over the 5-year MACRS schedule. For a business in the 25% tax bracket, the combined ITC plus depreciation tax benefits total approximately $51,250 — effectively covering more than half the system cost through tax savings alone.

The Inflation Reduction Act also introduced additional ITC bonuses for commercial projects. A 10% domestic content bonus applies when solar panels and components are manufactured in the United States. A 10% energy community bonus applies when the system is installed in a community with historical fossil fuel employment or a retired coal plant. Meeting both criteria increases the commercial ITC from 30% to 50%. Our Solar Panel Calculator can help estimate system sizing for commercial installations.

How to Stack Incentives for Maximum Savings

The key to maximizing solar savings is stacking every available incentive. Here is a real-world example for a homeowner in New Jersey installing a 7 kW system in 2026.

In this New Jersey example, the homeowner ends up $18,440 ahead over 10 years — the system more than pays for itself. Not every state is this generous, but even in states with minimal incentives beyond the federal ITC, solar typically pays for itself within 8-12 years and generates $30,000-$60,000 in cumulative savings over its 25-year lifetime. Our Solar Savings Calculator models these incentive stacks for your specific state and situation.

Best States for Solar Incentives in 2026

While every state benefits from the federal 30% ITC, state-level programs create dramatic differences in solar economics. Here are the top 10 states for solar incentives in 2026, ranked by total incentive value (including ITC, state credits, SRECs, net metering, and property/sales tax exemptions).

1. New Jersey — Full retail-rate net metering, high SREC values ($150-$200), property and sales tax exemptions, and strong sunshine make NJ one of the best solar markets in the country despite not being in the Sun Belt. 2. Massachusetts — SMART program provides performance-based incentives comparable to SRECs at $200-$280/MWh, plus net metering and a 15% state tax credit. 3. New York — 25% state tax credit (up to $5,000), NY-Sun rebates, VDER net metering successor, and property/sales tax exemptions. 4. Maryland — $1,000 state tax credit, SRECs ($40-$60), full net metering, and property tax exemption. 5. South Carolina — Generous 25% state tax credit (no cap), net metering, and property tax exemption.

6. Connecticut — RSIP rebate ($0.25-$0.43/W), net metering, sales and property tax exemptions. 7. Rhode Island — REF and REG programs, full net metering, sales and property tax exemptions. 8. Colorado — Xcel Energy rebates, net metering, property tax exemption, strong solar irradiance. 9. Minnesota — Solar*Rewards program, net metering, property tax exemption, Made in Minnesota incentive. 10. Arizona — $1,000 state tax credit, property tax exemption, and the highest solar irradiance in the country, which compensates for less generous net metering policies. Compare your options with our EV Savings Calculator to see how pairing solar with EV charging maximizes your incentive benefits.

Battery Storage Incentives

Battery storage systems qualify for the 30% federal ITC as standalone installations — they no longer need to be paired with solar panels (a change made by the IRA in 2023). This means you can add a battery to your existing solar system or install a standalone battery for backup power and time-of-use optimization, and still claim the 30% credit.

Several states offer additional battery-specific incentives. California's Self-Generation Incentive Program (SGIP) provides rebates of $150-$850 per kWh for battery storage, with higher rates for customers in fire-risk areas or low-income households. New York's Clean Energy Standard provides battery incentives through Con Edison and NYSERDA. Massachusetts SMART program provides adders for solar-plus-storage systems. Oregon's Solar + Storage rebate provides up to $2,500 for battery installations.

The economics of battery storage improve significantly when incentives are layered. A Tesla Powerwall at $11,500 installed receives a $3,450 federal ITC (reducing cost to $8,050). In California with SGIP, an additional $2,025 rebate brings the net cost to $6,025. Combined with $800-$1,200 in annual TOU arbitrage savings, the payback period drops to 5-7 years.
