Solar incentives can significantly reduce your cost—but the landscape changed dramatically at the end of 2025. I created this guide because I kept seeing homeowners get confused by outdated information. Here is what is actually available now, what is gone, and how to maximize the incentives you can still get.
I have helped homeowners in New Jersey, Massachusetts, Connecticut, and California navigate these incentives since 2018. The single biggest mistake I see? People reading articles from 2024 that still promise a 30% federal credit for purchased systems. That is gone now. But the good news is there are still ways to benefit—you just need current, accurate information.
Federal Investment Tax Credit (ITC)
The federal solar Investment Tax Credit has been the biggest incentive driving residential solar adoption. Here's the current status:
| Ownership Type | Credit Available | Who Claims It | Through |
|---|---|---|---|
| Cash Purchase | None (25D expired) | N/A | Expired Dec 2025 |
| Solar Loan | None (25D expired) | N/A | Expired Dec 2025 |
| PPA (Power Purchase Agreement) | 30% | Solar company | Dec 31, 2027 |
| Solar Lease | 30% | Solar company | Dec 31, 2027 |
What This Means for Homeowners
If you buy solar with cash or a loan in 2026, there is no federal tax credit available for you to claim. This is a significant change from previous years.
However, if you go with a PPA or lease, the solar company claims the 30% credit and uses it to lower your monthly payment or electricity rate. You still benefit from the credit—just indirectly.
2026 ITC Changes Explained
Here's what happened and why:
The "One Big Beautiful Bill" (July 2025)
As part of a larger legislative package in July 2025, the residential clean energy credit (Section 25D) was allowed to expire at the end of 2025. This provision had provided the 30% tax credit for homeowner-purchased solar systems.
Why PPA/Lease Still Works
Commercial solar projects use a different tax credit mechanism (Section 48E), which was NOT affected. Since PPAs and leases are technically commercial projects—the solar company owns the system—they still qualify for the 30% credit through 2027.
If You Installed Before 2026
Good news: If your system was installed and operational before December 31, 2025, you can still claim the 30% credit on your 2025 tax return. There was no retroactive repeal.
State Incentives Overview
While the federal credit for purchases is gone, many states offer their own incentives that can significantly reduce your cost:
| State | Key Incentives | Estimated Value |
|---|---|---|
| California | SGIP (battery), NEM 3.0 | $150-$200/kWh (battery) |
| Massachusetts | SMART program, SRECs, state credit | $5,000-$15,000+ |
| New Jersey | SRECs (TRECs), sales tax exempt | $3,000-$10,000+ |
| New York | NY-Sun, state tax credit (25%) | $5,000-$10,000 |
| Connecticut | RSIP, Green Bank financing | $2,000-$5,000 |
| Rhode Island | REF program, net metering | $2,000-$4,000 |
| Pennsylvania | SRECs, local rebates | $1,000-$5,000 |

SRECs (Solar Renewable Energy Credits) Explained
In some states, you can earn money by selling SRECs—certificates representing the clean energy your solar system produces.
How SRECs Work
- Your solar system produces electricity
- For every 1,000 kWh (1 MWh) produced, you earn 1 SREC
- You sell SRECs to utilities who need them to meet renewable energy requirements
- SREC prices vary by state and market conditions
SREC Values by State
| State | SREC Value (approx) | Annual Earnings (7 kW system) |
|---|---|---|
| New Jersey (TREC) | $200-$250/SREC | $1,600-$2,000 |
| Massachusetts | $250-$350/SREC | $2,000-$2,800 |
| Pennsylvania | $30-$50/SREC | $240-$400 |
| Illinois | $70-$90/SREC | $560-$720 |
Note: SREC values fluctuate based on market conditions. These are approximate current values.
State Tax Credits
Several states offer their own tax credits on top of (or in lieu of) federal incentives:
| State | Credit | Max Value |
|---|---|---|
| New York | 25% of system cost | $5,000 |
| Massachusetts | 15% of system cost | $1,000 |
| South Carolina | 25% of system cost | $3,500 |
| Arizona | 25% of system cost | $1,000 |
State tax credits are claimed on your state income tax return, similar to how the federal credit worked.
Utility Rebates
Some utilities offer upfront rebates for solar installation. These are less common than they used to be, but still available in some areas:
- Austin Energy (TX): $2,500 rebate
- LADWP (Los Angeles): Various programs
- Xcel Energy (CO, MN): Performance-based incentives
- Various Massachusetts utilities: SMART program payments
Check with your specific utility—rebate programs change frequently and may have limited funding that runs out.
Property Tax Exemptions
Solar panels increase your home's value, but many states exempt this increase from property taxes:
States with Full Property Tax Exemptions
- California
- Massachusetts
- New Jersey
- New York
- Texas
- Arizona
- Connecticut
- Florida
- ...and many others
This means your home value goes up (studies show 3-4% on average), but your property taxes don't increase. It's a hidden benefit many homeowners don't realize.
How to Maximize Your Incentives
1. Check All Available Programs
Don't assume your installer knows about every incentive. Research state programs, utility rebates, and local incentives independently.
2. Consider PPA/Lease for Federal Benefit
Since the cash purchase credit is gone, PPA and lease options now include the only way to benefit from the federal 30% credit. Compare the economics carefully. Learn more about financing options →
3. Time Your Installation
Some incentive programs have limited funding or scheduled step-downs. The 48E credit for PPAs/leases drops to 26% in 2028, so sooner is better.
4. Stack What You Can
Many incentives can be combined. You might get PPA savings (from the company's 30% credit) PLUS state tax credits PLUS SRECs PLUS property tax exemption.
