Why Lake County Homeowners Choose Solar
More Lake 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 Lake 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 Lake Michigan Weather
Lake County’s shoreline brings lake-effect snow, real winter cold, 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 projects on ComEd’s grid in the Chicago area. 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 Lake County
Lake 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 real ComEd-territory projects in the Chicago area. 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.
Every SolQ Lake County City Page
This page covers Lake County as a whole. For a page built specifically around your city’s permitting, streets, and local landmarks, use the directory below — every SolQ page confirmed to sit inside Lake County.
Waukegan, IL
Lake County’s seat and one of the largest cities on Illinois’s Lake Michigan shoreline. Covers Waukegan, North Chicago, Gurnee, and Park City.
Vernon Hills, IL
A village that sits entirely within Lake County along the Milwaukee Avenue (US-45) corridor. Covers Vernon Hills, Mundelein, Libertyville, and Lincolnshire.
Highland Park, IL
A North Shore city on a 100-foot bluff above Lake Michigan, about 25 miles north of downtown Chicago. Covers Highland Park, Highwood, and Deerfield.
Buffalo Grove, IL
A Chicago suburb split between two counties — about three-quarters of Buffalo Grove sits in Lake County, the rest in Cook County. Covers Buffalo Grove, Wheeling, and Long Grove.
Antioch, IL
A village on the Wisconsin state line, built around the Chain O’Lakes waterway system in northern Lake County. Covers Antioch, Lake Villa, Lindenhurst, and Old Mill Creek.
Gurnee, IL
Split by the Tri-State Tollway into an older east side and newer west side, home to Six Flags Great America and Gurnee Mills. Covers Gurnee.
Mundelein, IL
A Lake County suburb along the Milwaukee Avenue corridor, anchored by Mundelein Seminary and a Metra-served downtown. Covers Mundelein.
Round Lake Beach, IL
A village along Round Lake in western Lake County, part of the closely linked Round Lake Area communities. Covers Round Lake Beach.
Zion, IL
A Lake Michigan shoreline city near the Wisconsin state line, laid out on a distinctive planned street grid. Covers Zion.
Buffalo Grove is included because most of the city (roughly three-quarters, per its own page) sits in Lake County; its remainder is in Cook County. This directory reflects only SolQ pages actually built and live as of August 2026 — not every Lake County municipality has a dedicated page yet.
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’s Chicago-Area Territory Near Lake County
We’ll be straight with you: SolQ doesn’t yet have a completed install on file inside any Lake County city page — Waukegan, Vernon Hills, Highland Park, Buffalo Grove, Antioch, Gurnee, Mundelein, Round Lake Beach, or Zion. What we do have is a verifiable track record elsewhere on ComEd’s grid in the broader Chicago area, real streets from our completed project records:
Street names shown, no addresses. 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; zero of those are located inside Lake County to date. We’d rather tell you that honestly than pretend otherwise.

About Lake County, Illinois
Lake County sits in the northeastern corner of Illinois, bordered by Lake Michigan to the east and Wisconsin to the north. With roughly 714,000 residents (2020 U.S. Census), it’s one of the collar counties immediately north of Cook County within the Chicago metropolitan area, and its 444 square miles include more water area than land — a reflection of its long Lake Michigan shoreline. Waukegan, the county seat, sits on that shoreline about 36 miles north of downtown Chicago. Naval Station Great Lakes, headquartered in North Chicago, is the U.S. Navy’s only recruit training center and one of the county’s largest employers. The county spans a wide range of communities: dense, diverse lakefront cities like Waukegan and North Chicago; wealthier North Shore suburbs like Highland Park, Lake Forest, and Deerfield; corridor villages like Vernon Hills, Mundelein, and Libertyville along Milwaukee Avenue (US-45); and, in western Lake County, lower-density and agricultural townships stretching toward the McHenry County line. ComEd is the electric delivery utility for essentially all of Lake County. SolQ installs throughout ComEd’s Lake County territory; if ComEd powers your home or property here, we can likely put you on solar. For full ComEd rate, rebate, and net-metering details across the territory, visit our ComEd Illinois hub. For a broader look at Illinois utilities, Illinois Shines, and how the process works statewide, visit our Illinois solar hub.
Is Your Lake County Home a Good Fit for Solar?
Most Lake 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 North Shore and lakefront 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, heat pumps, and multi-unit properties often need a larger array.
Your Home’s Roof Type
From established lakefront homes to newer builds farther inland, 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 Lake County
ComEd is the electric delivery utility for essentially all of Lake County. Here’s the real breakdown, not a one-size-fits-all pitch.
ComEd
Northern Illinois
ComEd serves all or part of 25 counties across northern Illinois, including Cook, DuPage, Kane, Will, McHenry, Kendall, and Lake County. Within Lake County, ComEd delivers power to essentially every city and township we cover, from Waukegan on the lakefront to Vernon Hills along Milwaukee Avenue and the North Shore communities around Highland Park; as with any address, we confirm your exact utility and account details before designing or quoting anything. 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 Lake 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 Lake 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 Lake 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
Lake 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 Lake County Chief County Assessment Office.
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 Lake 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 western Lake County’s farmland. No guaranteed-savings pitch either way; we’ll walk through what actually applies to your property while we’re already evaluating it.
Premium Equipment We Install

Frequently Asked Questions
Is Lake County entirely served by ComEd?
Essentially all of Lake County is in ComEd’s service territory, which covers all or part of 25 northern Illinois counties. As with any address, we confirm your exact utility and account details before designing or quoting anything.
Which SolQ pages cover Lake County cities specifically?
SolQ has dedicated city pages for Waukegan (the county seat), Vernon Hills, Highland Park, Buffalo Grove, which sits mostly in Lake County with the rest in Cook County, Antioch, near the Chain O’Lakes on the Wisconsin state line, Gurnee, Mundelein, Round Lake Beach, and Zion. This page covers the county as a whole and links to each of those city pages.
Is Buffalo Grove really in Lake County?
Mostly. Buffalo Grove is a Chicago suburb split between two counties: about three-quarters of the city sits in Lake County, with the remainder in Cook County. We include it in this directory for that reason, but it’s worth knowing if you’re on the Cook County side.
Is solar really “free” in Lake 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 Lake County yet?
Not yet on file in Waukegan, Vernon Hills, Highland Park, Buffalo Grove, Antioch, Gurnee, Mundelein, Round Lake Beach, or Zion specifically. We do have a verifiable track record of completed installs elsewhere on ComEd’s grid in the Chicago area, plus 61 completed installs statewide 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 Lake 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.
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.
Who handles solar property-tax filings in Lake County?
Illinois’s alternate property-tax valuation for solar caps the assessment impact rather than exempting it, and requires a filing with the Lake County Chief County Assessment Office. 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 Lake 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.
Ready to Get Started?
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; confirm current eligibility with your tax advisor. SolQ does not yet have completed installs on file within Lake County (Waukegan, Vernon Hills, Highland Park, Buffalo Grove, Antioch, Gurnee, Mundelein, Round Lake Beach, or Zion); local proof shown above reflects real, completed ComEd-territory projects elsewhere in the Chicago area. Population, geography, and utility-territory figures cited above are sourced from the U.S. Census Bureau, Wikipedia, and ComEd’s own published service-territory description.
