Why Will County Homeowners Choose Solar
Will County is Illinois’s fourth-most-populous county, and more homeowners here 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 Will 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 Northern Illinois Weather
Will County stretches from dense Chicago-suburb development in the north to open farmland in the south and west, with real winter cold and humid summers throughout. 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 northern Illinois. See the honest picture below, not stock photos.
About Will County
Will County is Illinois’s fourth-most-populous county, with an estimated 2026 population of roughly 715,500, up from 696,355 at the 2020 census. Joliet, the county seat, is Illinois’s third-largest city, anchored by the historic Rialto Square Theatre and Joliet Junior College, the first public community college founded in the United States. ComEd is the electric delivery utility for Joliet and essentially all of Will County, and the company maintains a regional headquarters in Joliet itself.
Four interstates cross the county, including I-55 and I-80, and that position has made Will County one of the busiest inland logistics hubs in North America. The CenterPoint Intermodal Center in Joliet and Elwood, built on the former Joliet Army Ammunition Plant site, pairs Union Pacific and BNSF Railway rail yards across roughly 6,400 acres and is often described as the largest inland port in North America, with major tenants including J.B. Hunt, Schneider National, and C.R. England. That density of large, flat commercial and warehouse roofs, alongside the open farmland that still covers much of southern and western Will County, means solar here isn’t just a residential story; it’s a commercial and agricultural one too.
Illinois’s solar property-tax treatment is an alternate valuation, not a full exemption, and it isn’t automatic: it’s filed at the county level with the Will County Supervisor of Assessments. SolQ walks Will County customers through that filing alongside the Illinois Shines REC application and the ComEd interconnection process, rather than leaving it as a surprise after installation. For full ComEd rate, rebate, and net-metering details, visit our ComEd Illinois hub.

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.
Real Proof From ComEd Territory in Northern Illinois
We’ll be straight with you: SolQ doesn’t yet have a completed install on file specifically within Will County. What we do have is a real, verifiable footprint on ComEd’s grid across northern Illinois, from our completed project records:
Street names shown, no addresses. ComEd-territory size range from these completed projects: roughly 5.5 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.
Will County Solar Installer Directory, by City
SolQ has built dedicated solar pages for the following Will County communities, each with its own local detail on permitting, proof, and property-tax filing. This directory links to every one of them.
Joliet
The Will County seat and Illinois’s third-largest city, home to the Rialto Square Theatre, Joliet Junior College, and the CenterPoint Intermodal Center just outside town.
Bolingbrook
Along the I-55 corridor and Historic Route 66, mostly in Will County with a small slice reaching into DuPage County; home to Ulta Beauty and WeatherTech headquarters.
Plainfield
A historic Route 66 downtown along Lockport Street, served by Plainfield CCSD 202, the county’s largest school district, with I-55 running along the village’s eastern edge.
Romeoville
Known as “Stone City” for its limestone-quarrying heritage, along the I-55 corridor between Bolingbrook and Joliet, and home to Lewis University.
New Lenox
Along U.S. Route 30 with I-80 on its southern edge and I-355 reaching in from the north, anchored by the $400 million Silver Cross Hospital campus.
Lockport
A historic Route 66 and I&M Canal town along the Des Plaines River, with a walkable limestone-block downtown and easy access to I-355 and I-55.
Homer Glen
About 32 miles southwest of the Loop, a low-density village of large wooded lots incorporated in 2001, bordering Lockport and Homer Township.
Elsewhere in Will County
SolQ installs throughout ComEd’s Will County territory, including Shorewood, Crest Hill, Mokena, Frankfort, and Manhattan, even where a dedicated city page doesn’t exist yet. If ComEd powers your address in Will County, we can likely put you on solar.
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 Customers, Real Stories
Hear directly from homeowners who made the switch with SolQ.
Commercial, Agricultural & Battery Storage in Will County
Will County isn’t only rooftops on single-family homes. The county’s warehouse and distribution corridor around the CenterPoint Intermodal Center means large, flat commercial roofs are common, and the farmland across southern and western Will County means agricultural operations are a real part of who asks us about solar here too. If you own a commercial building or working farmland in Will County, ask SolQ about a commercial or agricultural solar evaluation alongside your residential quote. ComEd also offers a separate Battery Storage Rebate of $300 per kilowatt-hour for systems enrolled in Rate BESH, on top of its Solar Generation Rebate; ask us about adding battery backup while we’re evaluating your property. Both are informational starting points, not guarantees of savings or eligibility, since commercial, agricultural, and battery-storage economics vary by site.
Frequently Asked Questions
Is solar really “free” in Will 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 Will County yet?
Not yet on file. We do have a verifiable track record of completed installs elsewhere on ComEd’s grid in northern Illinois, plus 61 completed installs statewide and more than 2,000 company-wide. We’d rather tell you that honestly than pretend otherwise.
What’s the difference between this page and SolQ’s individual Will County city pages?
This page is a county-wide overview and directory: general Will County facts, ComEd territory information that applies countywide, and links to every city-specific page SolQ has built so far (Joliet, Bolingbrook, Plainfield, Romeoville, New Lenox, Lockport, and Homer Glen). Each city page then covers that community’s specific local landmarks, permitting notes, and nearby proof in more depth.
Is the federal solar tax credit still available in Will 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 homeowners keep the RECs from their Will 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 in Will County?
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 the property-tax filing work for solar in Will County?
Illinois uses an alternate valuation that assesses your home as if it had a conventional heating/cooling system instead of solar, applying whichever value is lower. It caps the tax impact rather than fully exempting it, and it isn’t automatic: it’s filed with the Will County Supervisor of Assessments. SolQ walks you through the filing alongside your Illinois Shines application.
Do permitting requirements vary by city within Will County?
Yes. Will County includes dozens of municipalities, each with its own building department, so permitting details can differ between, for example, Joliet, Plainfield, and New Lenox. SolQ confirms the specific requirements for your address alongside the ComEd interconnection filing.
How much does a solar system cost for an average Will 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.
How long does a Will 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.

Free, no-obligation estimate. No “free solar” pitch, no pressure.
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 Will County Supervisor of Assessments); confirm current eligibility with your tax advisor. SolQ does not yet have completed installs on file within Will County; local proof shown above reflects real, completed ComEd-territory projects elsewhere in northern Illinois. Population and county figures cited above are drawn from publicly available U.S. Census Bureau estimates and are general reference information, not SolQ data. This page is a county-wide directory and overview; it runs longer than a typical single-city page because it summarizes multiple communities in one place. Content verified as of August 2026.
