Peoria Electricity Prices
Electricity prices have climbed in recent years, making the bill an important part of understanding solar in Peoria.
For Peoria households, Illinois figures offer useful state-level context: the average price rose from 13.2¢ per kWh in 2021 to 15.9¢ in 2024. The U.S. average reached 16.5¢ in 2024.
A solar system can reduce the amount of grid electricity a household needs to buy. Its effect on bills depends on system design, energy use, utility rules, and the cost of installation.
Over the long term, generating some electricity at home may help a household manage exposure to changing grid rates. The overall value depends on upfront costs, system performance, and how much electricity the home uses.
Price of Energy: Illinois vs National Average
Peoria Area Utility Providers
In Peoria, Ameren Illinois is the utility represented in this comparison. The latest figures available are from 2023, when its electricity price was 17.0¢ per kilowatt-hour.
Ameren Illinois’ 2023 price was above the Illinois average of 15.70¢ per kWh and the national average of 16.0¢. These figures show the difference, but do not identify what caused it.
Solar panels can supply some of a household’s electricity, reducing how much it draws from the grid. The effect on a Peoria household’s bill depends on its electricity use and how much solar power the system produces.

Illinois Solar Incentives
Peoria homeowners may find state and utility programs that help offset eligible solar or battery costs. Explore solar incentives in Illinois.
Illinois Shines offers qualifying rooftop and community-solar projects REC-contract value, applied according to contract. Illinois Solar for All supports eligible households, nonprofits, and public facilities with reduced or no upfront costs and required bill-savings protections.
ComEd and Ameren offer eligible customers $300-per-kW solar rebates and $300-per-kWh battery rebates, subject to program rules. Illinois’ alternate solar property-tax valuation is not an automatic exemption. With LightReach leasing, Palmetto handles the commercial ITC and passes savings through 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 |
| Ameren Illinois Distributed Generation Rebate (DS-1 and DS-2) | Utility solar rebate | Eligible Ameren residential DS-1 and small-commercial DS-2 customers may receive $300 per kW-DC for qualifying customer-owned solar generation. | Learn More |
| Ameren Illinois Battery Storage Rebate (DS-1 and DS-2) | Utility battery storage rebate | Eligible Ameren residential DS-1 and small-commercial DS-2 customers may receive $300 per kWh for qualifying battery storage charged by an on-site renewable generator. | 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.
Ameren Illinois lists a $300-per-kW-DC rebate for qualifying distributed-generation systems for residential DS-1 and small-commercial DS-2 customers. The rebate can lower the upfront cost of eligible solar equipment; the amount is calculated using qualifying system capacity and is subject to the utility’s current program requirements.
Smart-inverter, equipment, interconnection, customer-class, and tariff rules apply. Ameren states that taking a generation rebate can affect delivery-service credits for customers with legacy net metering. Check your rate, interconnection date, and current tariff with Ameren before accepting the rebate, particularly if you have legacy full-retail net-metering service.
Ameren Illinois lists a $300-per-kWh rebate for eligible storage systems for residential DS-1 and small-commercial DS-2 customers. The rebate can offset part of the installed cost of a qualifying battery, based on its eligible capacity and the current utility program requirements.
Ameren requires storage included in a rebate application to be charged by an on-site renewable generator, and smart-inverter, equipment, interconnection, customer-class, and tariff requirements apply. Ameren indicates that a storage-only rebate does not trigger the specific legacy-net-metering consequence associated with a generation rebate, but customers should confirm their own tariff and billing treatment 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 Peoria
Verify the license
Illinois does not have a general state contractor license. Instead, Illinois Commerce Commission (ICC) certification is required before covered distributed-generation installation work—generally the electrical wiring and connections needed to interconnect a system with the utility distribution system. Planning or project management alone is not included, so ask what each contractor and subcontractor will do and who is responsible for the electrical work. Use the ICC’s installer lookup to check certification. Roofing work may separately require an IDFPR roofing-contractor license, depending on its scope; ask whether that applies to your project and who will perform that work.
Look for certified installers
Ask who will actually install the system, what credentials they hold, and whether those credentials apply to the people on your roof and doing the electrical work. NABCEP offers solar credentials; manufacturer certifications relate to particular manufacturers and products. Ask which credentials the installer has and what they cover. Treat certifications as useful comparison points, not guarantees of workmanship or production, and check references and contract details too.
Compare quotes the same way
Request written quotes with matching scope and compare each item side by side. A lower monthly payment may reflect different system size, financing terms, or equipment, so look beyond the headline price.
- System size in kilowatts (kW) and price per watt.
- Panel and inverter brands and models.
- Estimated production in kilowatt-hours per year (kWh/year), and the assumptions behind the estimate.
- Warranty terms for panel product and performance, inverter, workmanship, and roof penetrations.
- Who handles permits, inspections, and utility interconnection.
- Total cost or monthly payment, plus any payment escalator and the terms that apply.
For context only, Palmetto reports a median installed system size of 9.8 kW and about 94 days from signing to installation. Those are Palmetto figures, not a required system size or a timeline to expect from every installer.
Permits, interconnection and your HOA
For privately funded residential work, the local unit of 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. Depending on your address, that may be Commonwealth Edison Co, Ameren Illinois Company, MidAmerican Energy Co, or City of Springfield – (IL). Confirm who submits the interconnection request and tracks approval. Illinois law limits HOA restrictions: an association may not prohibit or effectively prohibit a solar energy system. Design and configuration rules are allowed within limits, including that they may not reduce estimated annual production by more than 10%. Ask the installer to review your HOA process and proposed design.
Red flags
- Pressure to sign the same day or before you can review the full agreement.
- Unlicensed or out-of-state crews, or unclear answers about who will perform the work and how to verify required Illinois credentials.
- Vague production estimates, or reluctance to explain what the estimate is based on.
- A large upfront deposit without clear written terms for what it covers and when it is due.
- Promises of federal homeowner tax credits for purchases made in 2026; homeowner credits ended December 31, 2025.
If a concern arises, the Illinois Attorney General’s Consumer Protection Division is a state contact for home-improvement and solar-sales complaints. For complaints specifically about an installer’s Part 468 certification or compliance, contact the ICC. Illinois Attorney General home-repair information.
Leasing Solar Panels
Solar financing options depend on your utility. In Peoria, a Palmetto Power Purchase Agreement (PPA) is available to eligible Ameren customers. PPA availability is also listed for ComEd customers elsewhere in Illinois; check your utility and address for current options.
With a PPA, you pay for the electricity the panels produce at an agreed price per kilowatt-hour, rather than a fixed monthly lease payment. Bills can vary by season as solar production changes. Learn more about the differences between buying and leasing solar.
A PPA can let you go solar without paying the full system cost upfront. Palmetto’s LightReach agreement includes system maintenance, so you don’t take on the same upkeep responsibilities as a cash owner. Review LightReach details and agreement terms.
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. Peoria residents served by Ameren Illinois can receive credits for excess solar electricity sent to the grid, but the rules depend on when the system received permission to operate.
Systems approved before Jan. 1, 2025 generally receive retail-rate net-metering credits; excess credits may expire in April or October. For systems approved on or after that date, exported power earns credits for supply and transmission charges, not delivery charges, taxes, or customer charges. Remaining credits roll over indefinitely toward eligible charges.
Yes, an owned solar system may increase a home’s value in Peoria, IL. Zillow’s study found homes with solar panels sold for about 4.1% more on average, though local sale prices vary and this is not a guaranteed increase.
This potential value increase applies to systems the homeowner owns, not leased or third-party-owned (TPO) systems. With a leased system, a buyer may need to assume the lease agreement, which can affect resale differently.
Peoria homeowners can go solar with a LightReach lease for no upfront cost and a low, fixed monthly payment. The calculator above estimates about $58/month for a small home, $79 for a medium home, and $108 for a large home.
A cash purchase is another option: estimated system costs range from $21,257 to $37,648, with a typical medium-home system around $28,095. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for details.
In Peoria, leasing lets you use provider-owned solar panels for a monthly payment, with no upfront cost. A typical 9.84-kW system is estimated at $79/month, based on Illinois’ 1,134 kWh/kW/year production ratio and $0.085/kWh rate.
LightReach covers panels, installation, monitoring, maintenance, and protection, including a 90% Production Guarantee. Palmetto owns the system, claims the commercial 30% ITC, and passes savings through lower payments. The lease payment is typically below the current electricity bill, so savings may begin when the system operates.
Illinois incentives for Peoria include Illinois Shines REC-contract value; income-qualified Illinois Solar for All, with reduced or no upfront costs and bill-savings protections; and Ameren rebates of $300 per kW for eligible solar and $300 per kWh for qualifying batteries. Eligible systems may use Illinois’ alternate property-tax valuation, which is not an automatic exemption.
After the 2025 federal law change, cash purchases no longer qualify for the 30% residential tax credit. With LightReach leasing, Palmetto claims the commercial ITC and passes savings through as lower monthly payments.
Yes. Solar panels work in Peoria, where the article reports an average of 4.7 peak sun hours per day. Panels can still generate electricity on cloudy days because they use daylight, though output is lower than in direct sun.
Production changes by season: Peoria’s longer, sunnier summer days generally bring higher output, while shorter, cloudier winter days bring less. A system can still produce useful energy year-round.
Solar panels are generally low-maintenance. Peoria homeowners can monitor system output and arrange an inspection if production drops unexpectedly or visible damage appears.
