If you’ve been thinking about solar for your Chicago-area home, 2026 is shaping up to be a pivotal year. State programs are evolving, new legislation is taking effect, and the incentives that make solar affordable are shifting beneath our feet. The question isn’t whether solar works, it’s whether you act now or wait. And waiting could cost you.
The Big Change: What Happened to the Federal Tax Credit?
Let’s address the elephant in the room immediately. If you’ve done any solar research in the past few years, you’ve probably seen references to the 30% federal tax credit. That credit is no longer available for residential homeowners.
The 30% Credit Is Gone, Here’s What That Means
The federal Investment Tax Credit (ITC) that offered 30% off solar system costs expired for residential owned systems on December 31, 2025. This was a major incentive that helped thousands of homeowners go solar, and its absence is understandably confusing for anyone researching solar in 2026.
You may still see old articles, outdated websites, or even some companies advertising this credit. Ignore them. That credit is gone for homeowners who purchase their systems outright.
Who Still Qualifies (Commercial and Lease Only)
The tax credit hasn’t disappeared entirely it’s just shifted. Commercial entities and third-party ownership models (like solar leases or Power Purchase Agreements) may still qualify under IRS section 48E through 2027 . This means that if you sign a lease or PPA through programs like Illinois Solar for All, your installer can capture business-related tax incentives and pass those savings to you in the form of lower monthly payments.
But as a homeowner who owns your system? You will not receive a direct federal tax credit. We mention this because transparency matters. Some companies still advertise “30% off!” based on outdated information. Windfree Solar tells you what’s actually available right now.

For official confirmation of the ITC phaseout, see the DSIRE database entry on federal solar tax credits.
What IS Still Available: Illinois State Incentives
Here’s the good news: while the federal credit is gone, Illinois has built some of the strongest state-level solar programs in the country. These programs are funded by Illinois ratepayers, not federal dollars, which means they’re stable and secure despite federal policy changes .
Illinois Shines (SRECs) Still the Main Event
The Illinois Shines program (formerly known as the Adjustable Block Program) remains the cornerstone of residential solar incentives. Through this program, you earn Solar Renewable Energy Credits (SRECs) based on the electricity your system is expected to generate over 15 years .
When you go solar, your utility purchases these credits in a one-time payment completed approximately one year after installation. For a typical 8.5 kW system, this payment can be worth approximately $11,000-$12,000 .
The program operates in “blocks” that fill up over time. As each block fills, the payment per SREC decreases. As of early 2026, Block 6 is active with SREC prices around $78 per credit . Block 7 will pay less, which creates genuine urgency for homeowners considering solar.
ComEd DG Rebate and Battery Storage
ComEd customers can receive a Distributed Generation (DG) rebate for installing smart solar inverter systems. The current rebate is $300 per kW of solar capacity installed . For an 8.5 kW system, that’s an additional $2,550 back in your pocket.
If you add battery storage, the rebate increases to $300 per kWh of storage capacity . A typical 3.36 kWh battery adds another $1,000+ to your rebate total.
Property Tax Exemption and Net Metering
Illinois law exempts solar installations from property tax assessments . While solar panels typically increase home value by $15,000-$25,000, this added value won’t increase your property tax bill. You get the benefit of increased home value without the burden of higher annual taxes.
For net metering, systems installed after January 1, 2025 are on “Smart Solar Billing” . You receive credits only for the supply portion of your excess electricity, not delivery charges. This makes battery storage more valuable, as it allows you to store and use more of your own power rather than sending it to the grid for partial credit.
Illinois Solar for All (Income-Qualified)
If your household income is at or below 80% of your area’s median income, you may qualify for Illinois Solar for All (ILSFA) . This program offers:
$0 upfront installation costs
Monthly payments capped at 50% or less of the energy value produced
No credit score requirements
Income thresholds are updated annually. As of the 2025-2026 program year, a single-person household in Cook County qualifies with income under approximately $65,000 .

Why “Act Now” Matters More Than Ever
We’re not saying “act now” to create false urgency. We’re saying it because the mechanics of Illinois solar programs create genuine financial advantages for acting sooner rather than later.
Block Pricing Declines Over Time
The Illinois Shines program is designed to gradually decrease incentive levels as adoption grows. Each block fills, and the next block pays less. Block 6 is active now. Block 7 will pay lower SREC prices. Block 8 will pay even less.
This isn’t a sales tactic it’s literally how the program is structured. Waiting 12-18 months could mean losing $1,000-$2,000 in upfront SREC payments on a typical residential system .
Program Capacity Is Filling Fast
In October 2025, the Illinois Power Agency filed its 2026 Long-Term Renewable Resources Procurement Plan, which proposed expanding program capacity to 1,000 MW for the 2026-2027 program year . This expansion reflects surging demand.
When more homeowners participate, blocks fill faster. The combination of high demand and expanding capacity means incentive levels will continue their planned decline. The homeowners who act earlier capture higher incentives.
Locking in Savings Against Rising Rates
ComEd rates have increased approximately 3-4% annually over the past decade. While fixed aggregation rates around 10.9¢/kWh are in effect for 2025-2026 , the long-term trend is upward.
When you go solar, you lock in your electricity cost at today’s rates. As utility rates rise, the value of your solar production increases proportionally. This isn’t speculation, it’s basic math. A system that saves you $1,400 this year might save you $1,600 in five years and $1,800 in ten.
New Legislation Takes Effect June 2026
The Clean and Reliable Grid Affordability Act (CRGA) was signed into law on January 8, 2026, and takes effect June 1, 2026 . This comprehensive energy legislation includes:
Expanded energy efficiency programs
New incentives for solar and battery storage
Grid-scale battery deployment to manage peak demand
Projected $13.4 billion in consumer savings over 20 years
While this law brings positive changes, it also signals the state’s commitment to evolving its energy programs. Incentive structures can shift, and the highest-value opportunities are often available to early adopters.

The “Act Now vs. Wait” Analysis
Let’s be honest about both sides of the decision. For some homeowners, acting now makes clear sense. For others, waiting might be the right call.
The Case for Moving Forward in 2026
Acting now makes sense if:
- You want maximum SREC payments: Block 6 incentives are higher than future blocks will be. Locking in today’s rates means thousands more in your pocket .
- You’re tired of unpredictable ComEd bills: Solar provides rate stability in a volatile energy market. With new data center demand and grid investments, rates are unlikely to decrease.
- You plan to stay in your home for 5+ years: Solar is a long-term investment. The payback period requires time to realize full savings.
- You want battery storage: The current DG rebate for batteries ($300/kWh) is valuable, and storage helps you maximize value under the new net metering rules .
- You qualify for ILSFA: If you’re income-eligible, there’s literally no downside, $0 upfront and immediate savings .
When Waiting Might Make Sense
Waiting could be the right choice if:
- Your roof needs replacement: Installing solar on a roof with less than 10-15 years of life left means you’ll eventually pay to remove and reinstall panels. Address roof replacement first.
- You have significant shade issues: Trees or buildings blocking sun might make solar uneconomical until you address the shading.
- You’re planning to move within 2-3 years: You may not recoup your investment before selling, though solar can increase home value.
- You’re not ready financially: Even with $0-down options, some homeowners prefer to wait until their situation feels right.
What to Ask Before You Decide
Before making any decision, ask yourself and potential installers:
- What are the current SREC prices, and how do they compare to last year?
- Does my roof get enough sun for good production?
- How much battery capacity makes sense for my usage patterns?
- What happens to my incentives if I sell my home?
- Can you show me projections with and without battery storage?
