Why Cook County Homeowners Choose Solar
More Cook 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 across the 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
Cook County sees real winter cold, wind-driven and lake-effect snow near the lakefront, and humid summers. 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 completed projects on file inside Cook County itself. 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.
Cook County, Illinois: The Real Picture
Cook County is Illinois’s largest and most populous county, with roughly 5.2 million residents — more than 40% of the entire state’s population, spread across Chicago and 135 suburban and city municipalities (23 cities, 1 town, and 111 villages, per Cook County’s own count). Chicago itself is the county seat. The county’s land area spans roughly 945 square miles, from Chicago’s lakefront through dense inner-ring suburbs, North Shore communities along Lake Michigan, northwest suburbs near O’Hare International Airport, and south suburbs along the Illinois Central and Rock Island rail lines. Property assessments for Cook County homeowners, including the alternate valuation available for solar energy systems, are handled by the Cook County Assessor’s Office; a handful of Cook County municipalities extend into neighboring DuPage, Will, Kane, or Lake counties, and homeowners in those areas may file with that county’s assessor or supervisor of assessments instead, depending on which side of the line their parcel sits. Cook County is served almost entirely by ComEd, with Chicago and its suburbs making up the largest concentration of ComEd customers anywhere in its 25-county northern Illinois territory.

What Makes SolQ Different in Cook County
Cook 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 completed ComEd-territory projects on file inside Cook 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 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 Across Cook County
We’ll be straight with you: as of this writing, SolQ has 3 completed installs on file inside Cook County itself — all three on our Mount Prospect, Palatine & Prospect Heights page. Real streets from our completed project records:
Street names shown, no addresses. The Mount Prospect system on West Bunting Lane is a confirmed ComEd account at 7.9 kW; the Prospect Heights system on North Stratford Road measures 2.2 kW. The Palatine system on West Wood Street is a completed install on record; we’re not stating a specific size for it here, since the recorded figure is unusually small and appears to reflect a partial or monitoring-only data entry rather than the full system. Beyond these three, SolQ has 61 completed installs statewide across Illinois and more than 2,000 company-wide, including other ComEd-territory projects in northern Illinois outside Cook County. From our completed project records, current as of August 2026.

Every Cook County City Page We’ve Built
This is the actual directory: 28 Cook County city pages SolQ has built and published, each with its own local context, honest install proof, and utility-specific FAQ. A few of these municipalities straddle Cook County’s border with a neighboring county; we say so on the page itself rather than quietly claiming the whole town. This page runs longer than a typical single-city page, on purpose, since a genuine county-wide directory of 28 real links needs the room. Start with your city below, or use this page as the county-wide reference.

Is Your Cook County Home a Good Fit for Solar?
Most Cook 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 parkway trees are common in Cook County’s older inner-ring suburbs. 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, heat pumps, and multi-unit properties often need a larger array.
Your Home’s Roof Type
From classic Chicago-style bungalows in the inner-ring suburbs to newer builds farther out in the county, 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 Cook County
ComEd is the electric delivery utility for Chicago and effectively all of Cook County. Here’s the real breakdown, not a one-size-fits-all pitch.
ComEd
Cook County & Northern IllinoisCommonwealth Edison — ComEd, an Exelon company — serves Chicago and effectively all of Cook County, alongside a broader 25-county northern Illinois footprint. 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 Cook 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 Cook 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.
Illinois Solar Incentives, Straight Talk
No State Income Tax Credit
Cook 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 Cook County Assessor’s Office, or the relevant neighboring county assessor if your municipality straddles the border.
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 Considering Battery Storage?
Cook County’s ComEd territory qualifies for a separate Battery Storage Rebate of $300 per kilowatt-hour (Rate BESH enrollment required), and outages do happen. Ask about pairing your solar system with battery backup while we’re evaluating your property; it’s not required, and we’ll walk through the real cost and tradeoffs, not a guaranteed-savings pitch.

Get My Free Solar DesignFrequently Asked Questions
Is solar really “free” in Cook 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.
How many completed solar installs does SolQ have in Cook County?
Three, as of this writing: real completed installs on West Bunting Lane in Mount Prospect (7.9 kW), West Wood Street in Palatine, and North Stratford Road in Prospect Heights (2.2 kW). We also have 61 completed installs statewide across Illinois and more than 2,000 company-wide, including other ComEd-territory projects in northern Illinois outside Cook County. We’d rather tell you the real number than round up.
Which Cook County cities does SolQ actually serve?
We’ve built 28 dedicated pages spanning 30 Cook County communities: Chicago, Cicero, Berwyn, Oak Park, Evanston, Skokie, Arlington Heights, Mount Prospect, Palatine, Prospect Heights, Orland Park, Tinley Park, Oak Lawn, Elk Grove Village, Park Ridge, Des Plaines, Homewood, Northbrook, Glenview, Schaumburg, Hoffman Estates, Bartlett, Wheeling, Hanover Park, Calumet City, Burbank, Lansing, Wilmette, Streamwood, and Barrington — listed with links in the directory above. If your Cook County address isn’t on that list yet, we still likely serve it; contact us to confirm.
My town straddles Cook County and a neighboring county. Does that affect permitting or property taxes?
It can. Towns like Orland Park, Tinley Park, Elk Grove Village, and Hoffman Estates each have a portion that sits in a neighboring county (Will, DuPage, or Kane). ComEd service and Illinois Shines eligibility don’t change based on county line, but your property-tax filing for solar’s alternate valuation goes to the Cook County Assessor’s Office or the relevant neighboring county assessor, depending on which side of the line your parcel sits, and permitting is handled by your municipality either way. We confirm specifics for your address before you sign anything.
Is the federal solar tax credit still available in Cook 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 Cook 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 much does a solar system cost for an average Cook County home?
Depends on system size, roof condition, and financing choice (Lease/PPA vs. cash/loan). SolQ provides a written estimate, not a guaranteed savings figure, after reviewing your ComEd usage.
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 the City of Chicago or my Cook County suburb have city-specific permitting requirements?
Permitting varies by municipality across Cook County’s 135 towns and cities; Chicago itself has its own permitting process, distinct from a suburb like Evanston or Oak Park. SolQ confirms specifics for your address alongside the ComEd interconnection filing.
Does SolQ offer battery storage in Cook County?
Yes, as an add-on alongside a solar system, most commonly the Tesla Powerwall 3. Cook County’s ComEd territory also qualifies for a separate Battery Storage Rebate ($300/kWh, Rate BESH enrollment required). We’ll walk through cost and tradeoffs during your consultation; it’s never required to go solar.
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 Cook 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.
