Rockford Electricity Prices
For homeowners considering solar installation in Rockford, IL, electricity rates are an important part of the long-term cost picture.
Illinois residential electricity averaged 13.2¢ per kWh in 2021 and 15.9¢ in 2024—about a 20% increase. These are statewide figures, not Rockford-specific rates. In 2024, the Illinois average was below the national average of 16.5¢.
A home solar system can generate some of a household’s electricity, reducing how much power it needs to buy from the utility. That may help limit exposure to future rate increases, though results depend on usage, system size, and utility policies.
Over time, using solar power at home may help offset purchased electricity and make energy costs more predictable. Its financial value depends on installation costs, system output, electricity rates, and how long the system is used.
Price of Energy: Illinois vs National Average
Rockford Area Utility Providers
In Rockford, ComEd is the utility represented in the available electricity-price data. Its 2023 rate was 14.8¢ per kilowatt-hour (kWh); 2024 utility data is not yet available.
That was below Illinois’s 2023 average of 15.7¢/kWh and the national average of 16.0¢/kWh. These comparisons show ComEd’s lower rate, but the supplied data doesn’t explain why prices differ.
For Rockford households, solar may reduce the amount of electricity bought from the utility. Its value depends on household use and how much a system produces, so compare estimated production with your electricity needs.

Illinois Solar Incentives
Rockford residents may qualify for state and utility incentives that help offset solar costs. See the solar incentives in Illinois listed below.
Illinois Shines offers REC-contract value; Illinois Solar for All provides eligible households and organizations reduced or no upfront costs with bill-savings protections. ComEd and Ameren offer qualifying solar and battery rebates; Illinois also has an alternate solar property-tax valuation.
Program and utility rules determine eligibility; the property-tax process is not an automatic exemption. With a LightReach solar lease, Palmetto handles the commercial ITC and passes savings through as lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Illinois Shines (Adjustable Block Program) | Solar renewable energy credit (REC) incentive | Qualifying Illinois rooftop-solar and community-solar projects can earn REC-contract value, which may reduce a customer’s project cost or be passed through according to the customer’s contract. | Learn More |
| Illinois Solar for All (ILSFA) | Income-qualified solar incentive | Eligible households and certain nonprofits and public facilities can access qualifying solar or community solar with reduced or no upfront costs and required bill-savings protections. | Learn More |
| ComEd Distributed Generation Rebate | Utility solar rebate | Eligible ComEd residential and small-load customers may receive a rebate of $300 per kW for qualifying customer-owned renewable generation equipment. | Learn More |
| ComEd Residential Battery Storage Rebate | Utility battery storage rebate | Eligible ComEd residential customers may receive $300 per kWh of qualifying battery storage capacity, subject to utility program and tariff requirements. | Learn More |
| Illinois Solar Energy System Property-Tax Valuation | Property-tax valuation provision | Eligible Illinois solar-energy-system improvements may use an alternate property-tax valuation process, which can limit how the system’s value is reflected in an assessment but is not an automatic tax exemption. | Learn More |
Illinois Shines supports qualifying on-site solar and community-solar projects by contracting for the renewable energy credits (RECs) the systems are expected to produce. For 2026–27, the published REC prices for small distributed-generation projects up to 10 kW AC are $70.37 per REC in Group A and $80.77 per REC in Group B; eligible customer-owned small systems that do not receive a federal clean-energy credit may qualify for an additional $20 per REC. A REC represents 1 MWh of generation, so the total value depends on estimated production, location, project category, and program rules—not simply system size.
The REC payment is made to the Approved Vendor, not automatically as a household rebate. The customer’s purchase, lease, or power-purchase agreement determines whether and how much value reaches the customer; review the Illinois Shines disclosure and contract before signing. Capacity and waitlist status can change, and qualifying small-system contracts approved on or after June 1, 2026 pay 50% at energization with the remainder paid over the following six years.
Illinois Solar for All uses REC contracts with approved project vendors to make solar more affordable for eligible participants. For qualifying residential rooftop projects, the program is structured to offer no upfront cost for many 1–4-unit homes, while other eligible properties may receive low- or no-upfront-cost offers; community-solar subscriptions are also available. The customer benefit is the project pricing and required savings protections, not a standard cash payment to every household.
Residential and community-solar household eligibility is generally based on gross income at or below 80% of Area Median Income, adjusted for household size and location. Program requirements, including savings, maintenance, and warranty protections, apply, and funding and application windows are limited. Confirm current eligibility and availability through the program before relying on an offer.
ComEd’s published rebate materials list a $300-per-kW rebate for qualifying residential and small-load customer-owned renewable generation. The rebate can lower the net upfront cost of an eligible solar installation, but the amount is based on qualifying system capacity and program rules; it is not a universal payment for every solar system.
Equipment, smart-inverter, interconnection, customer-class, and tariff requirements apply. If you are on legacy full-retail net metering, taking a generation rebate may affect your delivery-service credits or legacy billing status under the applicable utility rules. Confirm the current rebate terms and the effect on your specific net-metering arrangement with ComEd in writing before applying.
ComEd’s published program materials list a storage rebate of $300 per kWh for eligible residential and small-load customers. The rebate can reduce the cost of a qualifying battery, with the payment determined by eligible storage capacity and the program’s terms. ComEd’s materials specify hourly supply service (BESH) for the residential storage rebate.
Eligible equipment, smart-inverter, customer-class, and tariff requirements apply; verify whether the battery must be paired with or charged by an on-site renewable generator under the current terms. Storage receiving a rebate on or after June 1, 2026 may also be subject to scheduled-dispatch requirements, with ComEd’s filed rider indicating service may begin no later than March 1, 2027. Confirm the obligation and any compensation with ComEd before applying.
Illinois law provides an alternate valuation process for eligible solar-energy-system improvements. A property owner may file a claim with the county chief assessment officer; depending on the system, property, and applicable assessment rules, the process can affect the assessed value used to calculate property taxes and may reduce the tax impact compared with ordinary valuation.
This is not a blanket exemption from property taxes and does not guarantee a particular dollar savings. Eligibility and the valuation calculation depend on the property and system, and the owner must follow the applicable filing process. Contact the county assessor and review the Illinois Department of Revenue guidance to determine whether your installation qualifies.

How to Choose a Solar Installer in Rockford
Verify the license
Illinois does not have a general state contractor license. Instead, the Illinois Commerce Commission (ICC) requires certification before covered distributed-generation installation work—generally, completing the electrical wiring and connections needed to interconnect a system with the utility distribution system. Planning or project management alone is not covered, so ask what work the contractor and its crews will perform and who is responsible for the electrical connections. Check applicable certification through the ICC’s distributed-generation installer lookup. Roofing work may separately require an IDFPR roofing-contractor license, depending on scope; ask whether that applies to your project.
Look for certified installers
Ask whether the person designing or installing your system holds a relevant credential from the North American Board of Certified Energy Practitioners (NABCEP), and what the credential covers. NABCEP certification is a qualification to consider, not a substitute for any ICC certification required for covered work. Also ask whether the installer is certified by the manufacturers of the specific panels or inverters in your quote. Request the credential details and confirm that the equipment and scope match; compare what each credential actually establishes rather than treating a logo as a guarantee of quality.
Compare quotes the same way
Ask each installer to quote the same project assumptions and provide the details in writing. A lower total can reflect a smaller system, different equipment, or different warranty coverage. Compare:
- System size in kilowatts (kW) and total price; calculate price per watt using the quoted system size.
- Panel and inverter brands and models, plus estimated annual production in kilowatt-hours (kWh/year) and the assumptions behind it.
- Warranty terms for panel product and performance, inverter, workmanship, and roof penetrations; note who handles a claim.
- Who handles permits, inspections, and the utility interconnection application.
- Total cost or monthly payment, what that payment includes, and any escalator.
Permits, interconnection and your HOA
For privately funded residential work, the local government handles any required plan review, permits, and inspections; requirements vary by location. The homeowner or installer applies to the electric distribution company (EDC) serving the property. Confirm which utility serves your address: it may be Commonwealth Edison Co, Ameren Illinois Company, MidAmerican Energy Co, or City of Springfield – (IL). Ask who will submit the interconnection request and keep you updated. Illinois’ Homeowners’ Energy Policy Statement Act says an association may not prohibit or effectively prohibit a solar energy system. It can set design and configuration requirements within limits, including that they may not reduce estimated annual production by more than 10% (765 ILCS 165/15 and 165/20). Review HOA requirements early.
Red flags
- Pressure to sign the same day, before you can review the contract or compare quotes.
- Unlicensed or out-of-state crews without a clear explanation of who is doing the work and who is responsible for required credentials.
- Vague production estimates, or no written explanation of the equipment, assumptions, and warranties.
- A large upfront deposit without a clear payment schedule and written scope of work.
- Promises of federal homeowner tax credits for purchases in 2026; homeowner credits ended December 31, 2025.
For concerns about home-improvement work, contractor conduct, or solar sales, contact the Illinois Attorney General’s Consumer Protection Division; for complaints specifically about ICC Part 468 certification or compliance, use the ICC complaint procedure.
Leasing Solar Panels
In Rockford, Palmetto offers a solar power purchase agreement (PPA) to eligible customers served by ComEd. With a PPA, you pay for the electricity your panels produce at an agreed price per kilowatt-hour, rather than buying the system upfront.
A PPA differs from a solar lease, which usually has a fixed monthly payment. PPA payments can vary with seasonal production—often higher in sunnier months and lower in winter—while costs averaged over the year may be similar. Learn more about buying or leasing solar.
Compared with paying cash and arranging maintenance yourself, a PPA can avoid a large upfront purchase and can include system maintenance through the provider. Terms and availability depend on your utility and agreement; explore Palmetto LightReach for details.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes. Rockford homes served by ComEd can receive credits for excess solar electricity sent to the grid, but the credit depends on when the system received permission to operate (PTO).
Systems with PTO before January 1, 2025 generally receive full-retail net-metering credits. For systems approved on or after that date, exports are credited at ComEd’s supply-and-transmission rate, not delivery charges; credits can offset those charges and roll over until used.
Yes—owned solar panels may increase a Rockford home’s resale value. Zillow found homes with solar sold for about 4.1% more on average. This national finding is not a guarantee; a home’s value can depend on the system’s condition, energy output, and buyer demand.
This potential value applies to purchased or otherwise homeowner-owned systems, not leased or third-party-owned (TPO) systems. A leased system may affect resale differently because the buyer may need to assume the lease agreement.
Rockford homeowners can choose the LightReach lease option with no upfront cost and a low fixed monthly payment. The calculator estimates $79 per month for a typical 2,000–3,000-square-foot home; payment estimates vary by home size.
Cash purchase is another option: the calculator estimates $28,095 for a typical 9.84-kW system, with smaller and larger home examples ranging from $21,257 to $37,648. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for specific pricing.
Leasing lets Rockford homeowners use solar panels without buying the system upfront. With Palmetto’s LightReach lease, one monthly payment covers the panels, installation, monitoring, maintenance, and protection program, including a 90% Production Guarantee.
A typical 9.84 kW system is estimated at about $79 per month, based on Illinois production of 1,134 kWh per kW annually and a rate of $0.085/kWh. Actual terms vary; savings can begin from day one when the lease payment is lower than your current electricity bill.
Solar can make sense in Rockford, IL if your roof gets good sun and your system is sized for your household’s electricity use. Long summer days support production, while snow, clouds, and shorter winter days can lower output.
The article estimates about $61,000 in 25-year savings for a typical system, based on stated assumptions; actual results vary with roof, usage, rates, and utility rules. LightReach, Palmetto’s solar lease program, removes the upfront cost barrier entirely: homeowners can go solar with no money down and start saving from day one.
Solar can be worth it financially in Rockford when the system’s cost is lower than the electricity expenses it offsets. With a LightReach lease, homeowners need no upfront investment and can start saving from day one because the monthly lease payment is typically less than their current electricity bill.
Your actual savings depend on your home’s energy use, roof, seasonal solar production, utility rates, and lease terms. You may still receive a ComEd bill for electricity you use when your panels aren’t producing enough.
Rockford residents may qualify for Illinois Shines REC-contract value, depending on the contract, or Illinois Solar for All, which offers eligible households reduced or no upfront costs and bill-savings protections. ComEd lists rebates of $300/kW for qualifying customer-owned solar and $300/kWh for eligible batteries.
Illinois allows alternate property-tax valuation for eligible solar; it is not an automatic exemption. The 2025 law ended the 30% federal residential tax credit for cash purchases. With LightReach leasing, Palmetto claims the commercial ITC and passes savings through.
