Why DuPage County Homeowners Choose Solar
More DuPage County homeowners are looking into solar every year, not because it’s free (it isn’t), but because it reduces what you owe ComEd every month and builds equity instead of renting your power indefinitely. Here’s why solar makes sense in DuPage County right now.
Lower Your Monthly Bill
Generate your own power and reduce what you owe ComEd every month, with $0-down financing options available through our lease/PPA partner.
Built for Chicago-Area Weather
DuPage County sees real winter cold, wind-driven snow, and humid summers along the I-88/I-355/I-290 corridors. Panels are mounted and angled to shed snow and hold up to seasonal swings, not just perform on a mild-climate spec sheet.
A Real Illinois Track Record
61 completed installs across Illinois to date, including real projects on ComEd’s grid in the Chicago suburbs. 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 DuPage County
DuPage County homeowners see national call-center installers 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, including real ComEd-territory projects in the Chicago suburbs. 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 ComEd’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 ComEd delivers.
Utility Meter
Tracks power flowing to and from the grid under ComEd’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 ComEd 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 ComEd 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 ComEd 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 ComEd’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 ComEd Territory Near DuPage County
We’ll be straight with you: across all nine DuPage County city pages SolQ has built so far — Naperville, Wheaton, Downers Grove, Elmhurst, Lombard, Villa Park, Addison, Carol Stream, and Glendale Heights — SolQ doesn’t yet have a completed install on file inside DuPage County. What we do have is a verifiable track record elsewhere on ComEd’s grid in the Chicago area, a few real streets from our completed project records:
Street names shown, no addresses. Cluster-wide size range, not attributed to a specific address: roughly 2.2 kW to 51.0 kW. 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.
DuPage County Solar Installation, City by City
SolQ has built dedicated city pages for nine DuPage County communities so far. Each one covers that city’s specific utility account details, neighborhood character, and honest install-proof picture. This page is the county-wide directory and overview; click through to a city below for the local specifics.
Naperville
Illinois’s fourth-most populous city and DuPage County’s original county seat (1839–1867), spanning DuPage and Will counties. Affluent, high-owner-occupancy neighborhoods well suited to cash or loan purchase and premium equipment.
Wheaton
DuPage County’s current seat since 1867, with established, tree-lined single-family neighborhoods. Also serves Glen Ellyn, Winfield, West Chicago, Warrenville, and Carol Stream.
Downers Grove
DuPage County suburb along the I-88 corridor, home to corporate campuses including Dover Corporation. Also serves Woodridge, Westmont, Lisle, and Clarendon Hills.
Elmhurst
Affluent DuPage County suburb along the I-290/I-88 corridor. Also serves Villa Park, Lombard, Oak Brook, and Addison, with established single-family neighborhoods well suited to rooftop solar.
Lombard
DuPage County suburb along the I-88/I-355 corridor. Also serves Glen Ellyn, Villa Park, Elmhurst, Oak Brook, and Addison, with established single-family neighborhoods well suited to rooftop solar.
Villa Park
DuPage County suburb centered on the historic Ovaltine district and the Illinois Prairie Path trailhead. Also serves Oak Brook, Elmhurst, Lombard, and Addison, with a mix of early-20th-century bungalows and newer construction.
Addison
DuPage County suburb anchored by the Addison Industrial District and Salt Creek. Also serves Wood Dale, Itasca, Bensenville, Villa Park, and Elmhurst, with established mid-century subdivisions and newer infill construction.
Carol Stream
DuPage County suburb west of Wheaton, developed largely from the 1960s onward. Also serves Glendale Heights, West Chicago, and Bloomingdale, with established single-family subdivisions well suited to rooftop solar.
Glendale Heights
DuPage County suburb bordering Carol Stream and Bloomingdale, with a dense mix of townhomes and single-family subdivisions built mainly since the 1960s.
Naperville and Wheaton have each served as DuPage County’s seat at different points in the county’s history; Wheaton has held the role since 1867. Naperville’s SolQ service area extends into neighboring Will County; the other six cities above sit entirely within DuPage County.

Is Your DuPage County Home a Good Fit for Solar?
Most DuPage 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 in DuPage County’s established, decades-old suburban neighborhoods 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 ComEd usage, not your roof size. Bigger homes, EVs, and heat pumps often need a larger array, part of why systems in our nearby ComEd project cluster range from around 2.2 kW up to 51.0 kW.
Your Home’s Roof Type
From established mid-century homes near Naperville, Wheaton, and Downers Grove’s downtowns to newer builds farther out, 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.
ComEd: What to Know in DuPage County
ComEd is the electric delivery utility for most of DuPage County, including Wheaton, Downers Grove, Elmhurst, and Lombard — the exception is Naperville, which has run its own municipal electric utility, Naperville Electric Utility, since 1899. Here’s the real breakdown, not a one-size-fits-all pitch.
ComEd
Northern IllinoisComEd serves essentially all of DuPage County. New solar customers choose whether to receive their net metering credit in kWh or as a monetary credit, a decision made at the time of application. New systems here are also eligible for a one-time Solar Generation Rebate of $300 per kilowatt of installed generating capacity (smart inverter required, capped at systems up to 5,000 kW), plus a separate Battery Storage Rebate of $300 per kilowatt-hour, which requires enrolling in ComEd’s Rate BESH and cannot combine with Community Solar. It’s not recurring, and it’s only available once per system; ComEd’s stated timeline is roughly 90 days after your system is energized and your application is complete.
Since January 1, 2025, new ComEd solar customers are placed on supply-only crediting rather than legacy full-retail net metering; the credit offsets only the Supply portion of your bill, not delivery charges and taxes. If your DuPage County system was installed and interconnected before December 31, 2024, you keep full legacy net metering for that system’s life, up to 30 years. We confirm exactly which terms apply 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 DuPage 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 ComEd, 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 DuPage County homeowners.
Supply-Only Net Billing, Since January 2025
Since January 1, 2025, new ComEd solar customers are automatically placed on supply-only net billing rather than legacy full-retail net metering. This applies to systems interconnected 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, up to 30 years.
A One-Time DG Rebate Is Available
ComEd offers a one-time Solar Generation Rebate of $300 per kilowatt of installed generating capacity, plus a separate $300 per kilowatt-hour rebate for battery storage (requires Rate BESH enrollment, cannot combine with Community Solar). Not a recurring credit.
Two Ways to Take the Credit
New ComEd customers pick kWh credits or a monetary credit at application; that choice sticks with your account. We explain both before you decide.
Illinois Solar Incentives, Straight Talk
No State Income Tax Credit
DuPage County solar economics run through Illinois Shines’ REC value and ComEd’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 DuPage County Supervisor of Assessments, the office that provides assessment data to local township assessors and the county Board of Review.
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.
Ask About Battery Storage Backup
ComEd’s grid sees real DuPage County storm activity, from summer thunderstorms to winter ice. If you’re already having us evaluate your property for solar, it costs nothing to also ask about a Tesla Powerwall 3 paired with your system. ComEd offers a separate one-time Battery Storage Rebate of $300 per kilowatt-hour (requires Rate BESH enrollment, can’t combine with Community Solar), and we’ll walk through whether it pencils out for your household — no pressure, no guaranteed-savings pitch, just the real numbers for your address.

Built Around Illinois’s Rules, Not a National Template
From ComEd’s net billing and rebate mechanics to Illinois Shines REC economics, every DuPage County proposal starts with your actual utility terms, not a copy-pasted estimate from a national call center.

About DuPage County
DuPage County is Illinois’s second-most populous county, with 932,877 residents recorded in the 2020 census and more than 930,000 today, spread across Naperville, Wheaton (the county seat since 1867), Downers Grove, Elmhurst, Lombard, Glen Ellyn, Hinsdale, Oak Brook, and dozens of other communities. Argonne National Laboratory, one of the U.S. government’s oldest and largest science and engineering research labs, sits in unincorporated southeast DuPage County. The county is also home to Fortune 500 and Fortune 1000 employers including BP America (Warrenville), Dover Corporation and Sara Lee Corporation (Downers Grove), and Navistar International (Lisle), alongside prosperous downtown business districts across its suburbs.
ComEd delivers electricity to most of DuPage County — Naperville is the notable exception, served by its own municipal electric utility rather than ComEd. SolQ installs throughout DuPage County regardless of which utility serves your address; if you’re in DuPage County, we can likely put you on solar.

Get My Free Solar DesignFrequently Asked Questions
Why is this a county page instead of a city page?
DuPage County covers dozens of separate cities and villages with their own permitting offices, HOAs, and neighborhood character. This page gives you the honest county-wide picture, ComEd and Illinois Shines mechanics that apply across all of DuPage County, and a directory linking to the specific city pages SolQ has built so far: Naperville, Wheaton, Downers Grove, Elmhurst, Lombard, Villa Park, Addison, Carol Stream, and Glendale Heights.
Is solar really “free” in DuPage 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 ComEd, and we don’t set program rules, REC pricing, or rebate terms.
Does SolQ have completed solar installs in DuPage County yet?
Not yet on file, across any of the nine DuPage County city pages we’ve built (Naperville, Wheaton, Downers Grove, Elmhurst, Lombard, Villa Park, Addison, Carol Stream, Glendale Heights). We do have a verifiable track record of completed installs elsewhere on ComEd’s grid in the Chicago area, plus 61 completed installs statewide across Illinois and more than 2,000 company-wide. We’d rather tell you that honestly than pretend otherwise.
Is the federal solar tax credit still available in DuPage 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 ComEd now. We’ll walk through what applies before you sign anything.
Do I keep the RECs from my DuPage County solar system, or does SolQ?
Depends on financing. Own your system (cash or loan) and you own the RECs, free to sell them into Illinois Shines. Finance through a Lease or PPA and the financing company typically owns the system and its RECs unless your contract says otherwise.
How does ComEd credit my solar production?
New customers choose kWh credits or a monetary credit, offsetting only the Supply portion of the bill. Systems interconnected before December 31, 2024 keep legacy full-retail net metering for up to 30 years. We walk through both before you decide.
How does DuPage County handle property tax on solar systems?
Illinois law caps the assessed value impact of a solar installation rather than exempting it outright: your home is assessed as if it had a conventional heating/cooling system, and whichever value is lower applies. It isn’t automatic; an application goes to the DuPage County Supervisor of Assessments, the office that supplies assessment data to your township assessor and the county Board of Review. We can walk you through the filing.
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.
Does permitting work the same way across all of DuPage County?
No. DuPage County has dozens of home-rule municipalities, each with its own permitting office, and some neighborhoods carry additional HOA or historic-district review. We confirm the specific requirements for your address alongside the ComEd interconnection filing rather than assuming one county-wide process.
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 DuPage County solar installation take, start to finish?
Many projects install within 30 to 60 days of signing, though Illinois Shines processing and ComEd interconnection review can extend timelines. Installation itself is usually a day or two.

SolQ is an independent solar provider and is a registered Designee under multiple Approved Vendors participating in Illinois Shines. SolQ is not affiliated with, endorsed by, or acting on behalf of the State of Illinois, the Illinois Power Agency, the Illinois Commerce Commission, ComEd, or any government agency. “Illinois Shines” and the Adjustable Block Program are administered by the Illinois Power Agency and its program administrator, not by SolQ. 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 (the DuPage County Supervisor of Assessments); confirm current eligibility with your tax advisor. SolQ does not yet have completed installs on file within DuPage County; local proof shown above reflects real, completed ComEd-territory projects elsewhere in the Chicago area.
