Why Tazewell County Homeowners Choose Solar
More Tazewell County homeowners are looking into solar every year, not because it’s free (it isn’t), but because it reduces what you owe Ameren Illinois every month and builds equity instead of renting your power indefinitely. Here’s why solar makes sense in Tazewell County right now.
Lower Your Monthly Bill
Generate your own power and reduce what you owe Ameren Illinois every month, with $0-down financing options available through our lease/PPA partner.
Built for Central Illinois Weather
Tazewell County sees hot, humid summers and real winter cold along the Illinois River. Panels are mounted and angled to shed snow and hold up to seasonal swings, not just perform on a mild-climate spec sheet.
An Honest Illinois Track Record
One documented completed install in Tazewell County to date, in Washington, plus 61 completed installs statewide across Illinois and more than 2,000 company-wide. See the honest picture below, not stock photos.
You’re Already Paying for Power. Why Not Own It?
Every month, a payment leaves your account for electricity, and that money buys you nothing you keep. Here’s the real difference between renting your power and owning it.
What Makes SolQ Different in Tazewell County
Tazewell County homeowners see national call-center installers and door-to-door sales teams pitching Illinois Shines like a coupon. Here’s what sets SolQ apart.
A Real Track Record, Not a Startup Pitch
More than 2,000 completed installations to date company-wide, including a documented Ameren Illinois-territory project right here in Tazewell County. A verifiable operating history, not a new logo and a sales script.
Verified Credentials, Not Just Claims
NABCEP-certified installation, an A+ BBB rating, and EnergySage’s 2026 Local Installer of the Year award. All independently verifiable, not self-reported.
We Explain Illinois Shines Instead of Overselling It
RECs, program capacity, and Ameren Illinois’s rebate eligibility explained honestly for your address, not a generic “go solar for free” pitch.
A Financing Fit, Not a Sales Quota
$0-down Lease or PPA through LightReach, or ownership through a Salal Credit Union loan or cash purchase. We walk through both so you choose what fits.

How Home Solar Actually Works
Understanding how a residential solar system works helps you ask the right questions before you sign anything. Here’s the short version.
Solar Panels
Mounted on your roof, panels convert sunlight into DC electricity. We size the array to your household’s actual usage, not a generic package.
Inverter
Converts DC power from the panels into the AC electricity your home actually runs on, the same current Ameren Illinois delivers.
Utility Meter
Tracks power flowing to and from the grid under Ameren Illinois’s tariff, so your system’s production is measured and credited accurately.
Monitoring
Track production from your phone, so you always know exactly what your system is generating.
What to Expect: Your Solar Installation Timeline
Illinois timelines run longer than some states because Illinois Shines processing and Ameren Illinois interconnection review add steps beyond installation itself. Many projects finish within 30 to 60 days of signing; we’ll give a project-specific timeline before you sign anything.
Free Consultation & Usage Review
We review your last 12 months of Ameren Illinois usage and use Aurora Solar’s industry-leading design software to precisely model your roof’s sun exposure and shading.
Custom System Design & Financing
We size your system to your actual usage, and you choose the financing route (Lease/PPA or cash/loan purchase) that fits your goals.
Illinois Shines Application & Interconnection
We handle the Illinois Shines project application through our Approved Vendor and file the interconnection application with Ameren Illinois on your behalf. This step is often the biggest factor in overall timeline.
Installation Day
Our NABCEP-certified crew installs your system. Most residential jobs are completed in a day or two, depending on system size.
Inspection & Permission to Operate
Local inspection and Ameren Illinois’s permission-to-operate sign-off happen before your system is switched on.
Monitoring & Ongoing Support
You get app access to track production in real time, and SolQ stays available if you ever have questions about your system.
Real Proof From Tazewell County’s Ameren Illinois Territory
SolQ has one documented completed install in Tazewell County to date — in Washington. We’d rather tell you that honestly than pad the number. Pekin, East Peoria, Morton, Creve Coeur, Marquette Heights, and Tremont don’t have a completed install on file yet. Here’s the real project, shown below with no house numbers:
Street name shown, no address. From our completed project records, current as of July 2026. SolQ has 61 completed installs statewide across Illinois and more than 2,000 company-wide.
About Tazewell County, Illinois
Tazewell County sits on the east side of the Peoria metropolitan area in central Illinois, with roughly 131,343 residents as of the 2020 U.S. Census. Its county seat and largest city is Pekin, situated along the Illinois River. Directly across the river from downtown Peoria is East Peoria, home to major Caterpillar Inc. facilities and the Levee District. Just south of East Peoria sit Morton — the self-described “Pumpkin Capital of the World” and home to Libby’s pumpkin cannery — and Washington, a fast-growing city along U.S. Route 24 rebuilt in the years after the 2013 EF4 tornado. Smaller communities Creve Coeur, Marquette Heights, and Tremont — Tazewell County’s original 1836 county seat, before it moved to Pekin in 1849 — round out our current coverage. Ameren Illinois is the electric delivery utility across all of Tazewell County, including every community listed above.

Check Coverage for My AddressIs Your Tazewell County Home a Good Fit for Solar?
Most Tazewell County homes are strong solar candidates. Here’s what we actually check before we design your system.
Roof Direction
South- and west-facing sections get the most consistent sun. East-facing roofs still perform well; production just shifts to a morning peak.
Shading
Mature trees near established neighborhoods in Pekin and East Peoria may need trimming. We use Aurora Solar’s precision modeling plus an on-site check, not a guess from a satellite photo.
System Sizing
Sized to your last 12 months of Ameren Illinois usage, not your roof size. Bigger homes, EVs, heat pumps, and multi-unit properties often need a larger array.
Your Home’s Roof Type
From established riverside homes in Pekin to newer builds in Washington and Morton, roof type matters less than available sun-facing space and usage.
Financing Options
Lease or PPA $0 DOWN
A multi-year lease or power-purchase agreement with no upfront cost, through our financing partner LightReach. You pay either a fixed monthly lease payment or a per-kWh rate for the power your system produces, not ownership of the equipment.
Cash or Loan Purchase
Own your system outright with no ongoing lease or PPA payment. Loan options available through Salal Credit Union, with specific term and rate disclosed as part of your written proposal.
Ameren Illinois: What to Know in Tazewell County
Ameren Illinois is the electric delivery utility across all of Tazewell County — Pekin, East Peoria, Morton, Washington, Creve Coeur, Marquette Heights, and Tremont all sit in its territory. Here’s the real breakdown, not a one-size-fits-all pitch.
Ameren Illinois
Central & Southern IllinoisAmeren Illinois, headquartered in Collinsville, serves Pekin, East Peoria, Morton, Washington, and the rest of Tazewell County alongside the rest of central and southern Illinois. Ameren customers choose between two export-crediting methods (kWh usage netting or monetary value netting) at the time of application, a decision that’s permanent once made. New systems in Tazewell County are also eligible for a one-time Distributed Generation rebate of $300 per kilowatt of installed generating capacity, plus a separate $300 per kilowatt-hour rebate for battery storage. It’s not a recurring credit, and it’s only available once per system.
Since January 1, 2025, new Ameren Illinois solar customers are automatically placed on Smart Solar Billing rather than legacy full-retail net metering. If your Tazewell County system was installed and interconnected before December 31, 2024, you keep full legacy net metering for that system’s life. We confirm exactly which terms apply to your account before you sign anything.
Illinois Shines: How the Incentive Actually Works
Illinois Shines is the state’s Adjustable Block Program, administered on behalf of the Illinois Power Agency to help the state meet its renewable energy goals. Here’s how it works for a Tazewell County system: your solar array creates Renewable Energy Certificates (RECs), the tradable proof that clean energy was produced. Through Illinois Shines, an Approved Vendor can sell those RECs into the program in exchange for payment, typically used to help offset your system cost. SolQ is a registered Designee under multiple Approved Vendors participating in Illinois Shines. We are not the State of Illinois, the Illinois Power Agency, the Illinois Commerce Commission, or Ameren Illinois, and we don’t control REC pricing or program capacity.
A few things worth knowing upfront: REC value depends on current program pricing and available block capacity, both set by the program administrator, not SolQ. This is factored into your financing rather than paid to you directly in most cases. If your system’s RECs are sold into Illinois Shines, you’re being compensated for that environmental attribute; you aren’t separately claiming the system was “free,” and we won’t tell you it is. We’ll show you the current program mechanics that apply to your specific proposal, not a number pulled from an old rate card.
Net Metering in Illinois: What Changed
If you’ve heard Illinois solar rules “changed” and weren’t sure what that meant, here’s the straight version for Tazewell County homeowners.
Smart Solar Billing, Since January 2025
Since January 1, 2025, new Ameren Illinois solar customers are automatically placed on Smart Solar Billing rather than legacy full-retail net metering. This applies to systems installed from that date forward.
Existing Solar Is Grandfathered
If your system was installed and interconnected before December 31, 2024, you keep full legacy net metering benefits for the life of that system.
A One-Time DG Rebate Is Available
Ameren offers a one-time Distributed Generation rebate of $300 per kilowatt of installed generating capacity, plus a separate $300 per kilowatt-hour rebate for battery storage. Not a recurring credit.
Expanding an Existing System
Ameren customers with legacy net metering can generally expand system capacity by up to 100% and keep full legacy benefit on the expansion. We walk through exactly what applies to your account before you decide.
Illinois Solar Incentives, Straight Talk
No State Income Tax Credit
Tazewell County solar economics run through Illinois Shines’ REC value and Ameren Illinois’s DG Rebate, not a state income tax credit, which Illinois doesn’t offer. Be wary of anyone pitching one.
Property Tax: Capped, Not Exempt
Illinois assesses your home as if it had a conventional heating/cooling system instead of solar, and applies whichever value is lower. It caps the tax impact rather than exempting it, and isn’t automatic; you (or SolQ) file with the Tazewell County Assessment Office (Supervisor of Assessments).
Federal Credit: Financing-Dependent Now
The 30% federal residential credit (Section 25D) ended for cash and loan purchases not completed by December 31, 2025. Lease/PPA agreements can still pass through a federal credit through 2027. See our FAQ for the breakdown.
Also Evaluating a Tazewell County Business or Farm Property?
If you’re weighing solar for more than one property, ask us about battery storage backup alongside your residential system, or about commercial and agricultural solar for a business, warehouse, or farm property elsewhere in the county — including Tazewell County’s surrounding farmland. No guaranteed-savings pitch either way; we’ll walk through what actually applies to your property while we’re already evaluating it.
Ask About Battery Storage & Commercial SolarPremium Equipment We Install
NABCEP-certified installation using trusted equipment, sourced through distributor CED Greentech. Panels shown below reflect what we’ve actually installed on Ameren Illinois’s grid, alongside our Qcells partnership for panels and battery storage.
SolQ also installs Qcells Q.PEAK solar panels, including Qcells’ AC module line (module-level power electronics built into the panel), and offers Qcells Q.HOME battery storage for backup power. Qcells is one of our panel and battery-storage manufacturer partners, alongside the brands shown here.

Get My Free Solar DesignFrequently Asked Questions
Is Tazewell County entirely served by Ameren Illinois?
Yes. Ameren Illinois is the electric delivery utility across all of Tazewell County, including Pekin, East Peoria, Morton, Washington, Creve Coeur, Marquette Heights, and Tremont. As with any address, we confirm your exact utility and account details before designing or quoting anything.
Which SolQ pages cover Tazewell County cities specifically?
SolQ has dedicated pages for Pekin (the county seat), East Peoria, Morton, Washington, Creve Coeur, Marquette Heights, and Tremont. This page covers the county as a whole and links to each of those pages.
Is solar really “free” in Tazewell County?
No, and we’ll never tell you it is. Illinois Shines pays for the RECs your system produces, which can meaningfully offset cost, but it isn’t free equipment or installation. A $0-down Lease or PPA means no upfront cash from you, not that the system has no cost; you’re paying for its power over the contract term instead.
Is SolQ affiliated with the State of Illinois, the Illinois Power Agency, or my utility?
No. SolQ is an independent installer and a registered Designee under multiple Approved Vendors participating in Illinois Shines. We are not the State of Illinois, the Illinois Power Agency, the Illinois Commerce Commission, or Ameren Illinois, and we don’t set program rules, REC pricing, or rebate terms.
Does SolQ have completed solar installs in Tazewell County?
Yes, one so far — a 12.5 kW system on Washington Road in Washington, IL, on Ameren’s grid. Pekin, East Peoria, Morton, Creve Coeur, Marquette Heights, and Tremont don’t have a completed install on file yet. We’d rather tell you that honestly than pretend otherwise; we also have 61 completed installs statewide across Illinois and more than 2,000 company-wide.
Is the federal solar tax credit still available in Tazewell County?
For cash and loan purchases, no. The 30% federal residential credit (Section 25D) ended for systems not completed by December 31, 2025. Lease/PPA customers still benefit indirectly: our financing partner owns the system and claims a separate federal credit for commercial-owned solar (Section 48E, active through 2027), part of how they offer $0-down payments below what you pay Ameren Illinois now. We’ll walk through what applies before you sign anything.
How does Ameren Illinois credit my solar production?
New customers choose kWh usage netting or monetary value netting at the time of application, a decision that’s permanent once made. Systems installed and interconnected before December 31, 2024 keep legacy full-retail net metering for the life of the system. We walk through both before you decide.
Who handles solar property-tax filings in Tazewell County?
Illinois’s alternate property-tax valuation for solar caps the assessment impact rather than exempting it, and requires a filing with the Tazewell County Assessment Office (Supervisor of Assessments). SolQ can help with that filing; confirm current eligibility with your tax advisor.
Who are SolQ’s financing partners?
For Illinois homeowners, SolQ offers $0-down Lease and PPA options through LightReach, and loan financing through Salal Credit Union for those who want to own their system outright.
What kind of warranty comes with my system?
Most panels carry a 25-30 year manufacturer warranty (varies by brand), most batteries carry 10 years, and inverters typically range 10-25 years. Lease/PPA agreements through LightReach typically include a bumper-to-bumper warranty with a production guarantee for the full term.
How long does a Tazewell County solar installation take, start to finish?
Many projects install within 30 to 60 days of signing, though Illinois Shines processing and Ameren Illinois interconnection review can extend timelines. Installation itself is usually a day or two.

Renewable Energy Certificate (REC) pricing and Illinois Shines block capacity are set by the program administrator and change over time; figures on this page are general program information, not a quote or guarantee for your system. Solar RECs are a form of compensation for your system’s environmental attributes, not a rebate on the equipment itself, and selling them does not make a system “free.” Savings, rebate, and incentive figures shown are general information and estimates, not guarantees. Actual results vary by system, usage, and current program terms. The federal residential solar tax credit (Section 25D) ended for cash/loan purchases completed after December 31, 2025; a separate credit may apply to third-party-owned Lease/PPA systems through 2027. Financing offered through third-party partners (LightReach for Lease/PPA, Salal Credit Union for loans); terms, including contract length and payment structure, are disclosed in your specific agreement and subject to partner approval. Illinois’s property tax treatment of solar is an alternate assessment method, not a full exemption, and requires an application to your county assessor; confirm current eligibility with your tax advisor.
