Solar Incentives for Rock Falls

Every dollar you can save on your solar installation — updated for 2026.

Last updated: March 2026

⚠

Federal ITC: Expired for Homeowners

The 30% residential ITC (Section 25D) expired December 31, 2025 via the One Big Beautiful Bill. Systems installed in 2026+ receive zero federal tax credit if homeowner-owned.

However, if you lease your system, the installer can still claim the business ITC through 2027 — and pass savings to you through lower lease payments. Contact us to see how much you can save with a lease.

Available Incentives

Even without the federal credit, Illinois has some of the best solar incentives in the country.

Best Incentive

Illinois Shines RECs (ComEd)

~$6,263*

Avg. est. lump sum (~18 months)

The Illinois Shines program pays you for the Renewable Energy Credits (RECs) your solar panels generate. You sign a 15-year production contract, and the estimated REC value of approximately $6,263 (based on average system size in Rock Falls) is paid as a lump sum within ~18 months of installation. Actual value varies based on your system size and production. The customer receives approximately 85% of the gross value — the remainder covers the approved vendor's fee and a 5% collateral held against underproduction. Cash/finance buyers receive this payment directly. Lease customers benefit through lower payments — the installer carries the 15-year contract liability.

REC Price: ~$75.48/REC
Contract: 15 years
Eligibility: 0-10 kW residential

DG Rebate (Solar)

~$1,650

$300/kW × ~5.5 kW avg.

Distributed Generation rebate from your utility under the Clean and Reliable Grid Affordability Act (CRGA). Received from your utility approximately 90 days after installation.

Property Tax Exemption

100%

Solar adds value to your home, but Illinois exempts 100% of that added value from property taxes. This is a permanent exemption with no sunset date. File PTAX-330 with your county assessor.

Solar for All (ILSFA)

No Payments

Official state program for income-eligible households. No solar payments, no upfront costs, no credit check. Guaranteed savings on your electricity bill. You may qualify if your household income is at or below 80% of your Area Median Income (AMI).

Net Metering

~6-8¢/kWh

Post-January 2025 installations receive credits at the supply rate only (~6-8¢/kWh), not full retail. Credits never expire and roll forward month to month. Pre-2025 systems are grandfathered at full retail for 30 years.

Battery Storage Rebate

$300/kWh

Add battery storage and receive $300 per kWh rebate. A 10 kWh battery gets $3,000. Stackable with solar DG rebate. The upcoming Virtual Power Plant program (launching mid-2026) will let you earn additional revenue from your stored energy.

Incentive Questions

Yes, for homeowner-owned systems. The 30% residential ITC (Section 25D) expired December 31, 2025. However, the business ITC still exists through 2027, which benefits lease/PPA customers — the installer claims the credit and passes savings to you.
Your solar installer handles the IL Shines application. They must be an Approved Vendor in the program. You sign a 15-year production contract, and the full REC value is paid as a lump sum within approximately 18 months of activation — not spread over the contract period.
Yes! The DG rebate, IL Shines RECs, property tax exemption, and net metering all stack together. Solar for All is a separate state program for income-eligible households — participants enjoy no solar payments and guaranteed savings.
The full REC lump sum is typically received within 14-18 months of system activation and IL Shines contract execution. It is a single payment, not installments over the 15-year contract period. Cash/finance buyers receive the check directly.
Yes, file form PTAX-330 with your county assessor's office after installation. This ensures the added home value from solar is exempt from property tax assessment.
